I like the way you are approaching this series, especially knowing that it's done and working already. I'll be following along closely. My mini mill conversion didn't go as smoothly as planned but I am making progress. A lathe will definitely be next though so this is great! Thanks, Tom Z
Just downloaded your Excels! Fantastic work Russ. Myself and many others appreciate your videos. We know you do them free of charge to us and I want you to know that we use your material to better our lives. Hopefully that's a small reward for the work you put in to make this content. Best Matt
+Matthew Dom Thanks Matt! My whole goal is to share with the community, and although it can be time consuming I actually enjoy it. I wish I had more time to make videos, I'm behind quite a bit right now.
It always seems to happen like that. There's more work than time or money. You doing a good job. I and others will wait patiently for your videos. Have fun! And I'll message you when I complete my conversion to let you know how it went.
I want to build both f your CNC conversions, but for the moment I don't have room for them. I'll watch anyway, as it's fascinating and the info is adaptable to something I do gave room for (almost!)...a mini mill CNC. When I can arrange for more ship space, I'll be watching again! Thanks! -- Mike
+russtuff You are a generous man! Thank you for the offer. Don't hold your breath though...it could be a while. Or not...we'll see. I'm reconsidering the plans all the time...I'd *like* the larger mill, I just have to figure a way to fit it in. The cost difference is negligible enough that space needed is the main decision factor.
+BigMjolnir I understand that. If I were in the mood to do another conversion I'd go with the Bolton 45 this time. Much larger and heavier, but not quite as much detailed info online. That's why I went with my mill. Hoss' plans were super helpful.
+russtuff I saw the CharterOak Automation mill at a model show last spring. Definitely larger, and surprisingly inexpensive for the manual version. It's on sale at the moment since they are moving to larger quarters. I'm definitely going to get Hoss' plans if I go the G0704 route. -- Mike
I'm loving this G0602 CNC conversion series. Thanks! Looking forward to the next one! I've ordered stuff from Automation Technologies, and they're good, but when I do a LinuxCNC conversion I order the stepper motors and drivers and the parallel I/O card as a bundle on eBay, usually from Longs Motor or Wantai. I like the low prices and the one stop shopping, and the quality is actually quite good. I believe it's comparable to Automation Technologies. Many people get combo driver cards, but I prefer one driver per motor. If I blow up a driver (hasn't happened yet), it's easy and cheap to replace a single driver. I usually have a spare ready to go, just in case. That's a good price on a real electrical enclosure. I've been using powder coated steel shop cabinets with stainless doors from Seville Classics. They were available at Sam's Club, but they stopped carrying the one I used and I had to buy the last two from the manufacturer's website. I LOL'd when you said you were originally considering upgrading from LinuxCNC to Mach. Bwa ha ha ha ha. Check out some of the conversational programming wizard add-ins for LinuxCNC. Not as pretty as the PathPilot extension of LinuxCNC from Tormach, but they generally get the job done. Hopefully, PathPilot threw down the gauntlet and the open source programmers working on LinuxCNC will pick up the gauntlet. Even if not, there are plenty of other ways to get G code into LinuxCNC. PyCam is one, although more for mills than lathes. For one off jobs, I like being able to have conversational programming on the machine. Barring that, a lot can be done with a little understanding of G code at the MDI screen. There are a few other LinuxCNC installation videos on UA-cam, but they're mostly out of date, and I'm sure yours will be more thorough. I think most people will be shocked to see how easy it is on a simple mill, lathe, gantry router, etc. I bought a tiny Sherline lathe so I could immediately convert it to my CNC Mini Lathe. It's been a lot of fun, and it didn't take that long to do. Most of the job was the electrical panel, because I'm an electrical engineer and even when I'm building a machine for my own use, I want to wire the panel properly. I took 60:1 video and the 20 hour build made a 20 minute video. I edited the video and added the narration, and then my iPod Touch died. I should send it off to recover my files. If so, I'll upload the video. If not, I'll be posting my CNC conversion videos for my Grizzly G1006 mill and my Clausing 4900 lathe.
+Liberty4Ever Thanks! I've never used that eBay vendor, but I'll check them out right now. I agree about the single drivers. I've been using a lot of the LinuxCNC scripts for my mill, but haven't used any for my lathe (or found any yet). Some of the mill ones are really good. I'm terrible with electronics, as you'll see in my upcoming video on the subject. It's taken me a lot of muddling through to get this done. Luckily one of my friends is an engineer and this crap comes naturally to him :)
Very awesome stuff brotha :) im starting to buy parts now i have a G0602 and a g0704 im interested in cncing them both! Very excited to see the content you have saved up thanks for sharing!
Your videos are GREAT for us beginners - please don't stop! I am about to take the big plunge and purchase machines same/comparable to the G0602 and G0704 or maybe slightly more expensive if greatly advantageous. If you were starting over today, would you still choose the same machines or would you go with something slightly different?
+Wayne Causey Thanks for saying :) I'm torn. I really like both of my machines, but like always, I have bigger machine envy. I really like the look of the ZX45 (also called an RF45) like the Bolton. They are quite a bit larger than the G0704 and not a lot of money more. The reason why I didn't go with the 45 is because I was nervous about tackling the CNC conversion. I bought Hoss' G0704 conversion DVD and it made the whole project really easy. That said, now that I know what I'm doing (and once I realized it's not that hard) I do sorta wish I had gone with the 45. The G0602 is still a great lathe, and I like it. If possible, I would buy the variable speed version right out of the box (it's a different G# and they didn't offer it when I bought my lathe). Again, however, if I could have afforded larger at the time, I probably would have gone larger.
A bit thrown off on the intro spread sheet, says milling machine, you can get stronger steppers by going to nema 24, most have the same hole pattern as the nema 23 ie 47.1mm you can get the closed loop version up to 5nm
Looking forward to hear your thoughts and opinions of LinuxCNC. I use Mach and It's never really given me problems, but was always curious about LinuxCNC.
+JamesPVill Once you figure it out, it's pretty solid. I think the LinuxCNC series I've already filmed (but not posted) is about 7 videos, so it should answer some questions :)
Love your videos Russ. I am working on converting a PM-1127VF I picked up. I am slowly getting all the parts in, just got the ball screws from China yesterday. I ordered them with the double ball nuts and got an insane deal. I was wondering if you have an encoder on you spindle? If not is it in the works?
+acartier1981 Cool! That looks like a great machine. I do have a spindle encoder ring, and I'll be discussing it in my next lathe video (hopefully out in the next week or two).
hi russtuff I was wondering if you have the part numbers for the 22 tooth pully because i went to sdp and looked up the part numbers listed and both part numbers are the same. i guess i could just find a pully that looks the same but i was worried about belt length being correct and wanted to follow your build. thank you.
The part number I have here still works: ua-cam.com/video/lvK7TDFJZhY/v-deo.html shop.sdp-si.com/catalog/product/?id=A_6A55-024DF1512 I'm no longer using this belt drive as I couldn't get it to run quietly for some reason. Now I'm using a ribbed belt setup... and it looks like I never made a video about it (hmmmm). You can see some of it here though: ua-cam.com/video/rH0dEqflykk/v-deo.html
hello, I really like your both Sam and your videos, you both doing very high tech videos, I have asked Sam question about his steppers motor and I was confusing if his setup using small nema 270 and 425 will under power the machine? but he confirmed that it will be fine, Now I see you are using way bigger motors than his once, and you was right when you said (you need power for drilling) and I am with you with that part. can you please tell which is the ideal setup (small motors) vs (big motors) Thank you very much keep up the great work! Oz
+Ozy Ozy The reason I went with bigger motors is because back in the day when John Grimsmo did his G0602 CNC conversion he went with 270oz motors on both axis. He told me he couldn't drill with them, and suggested going with something bigger. Mine might be overkill, but the exact reason I went with them is because they are the same steppers I use on my mill. Since my electronics enclosure is for both my mill and my lathe, I wanted the motors to match on both machines so that I wouldn't have to change settings on my stepper drivers. If Sam says what he has is working, then I see no problem going with the same setup he has. One thing to consider, is that while larger steppers will provide more torque, they have slower accelerations. The big NEMA34 I'm using on my Z-Axis takes a bit more time to reach top RPM than a NEMA23 would, due to its mass. I haven't really tested it's drilling capabilities yet though, so I can't say for sure if the NEMA34 is really going to be overkill or not.
+russtuff thank you very much to clear that out in a detailed way.. I will go ahead and get same what you use. I just contacted Duncan at cnc4pc and he recommend the new board c11gs he also suggest to use the most advanced cards that will cost around $300 to have complete cnc futures, But I will just get the C11gs and save $$$ I think c11gs can get me threading, coolant, and spindle control! So that is enough for that little project I appreciate your replay sir Oz
+Ozy Ozy Awesome. Duncan has always been good to help me when I needed it. Out of curiosity, what else did he recommend that was going to cost so much?
+russtuff sorry for my delay of my subscribing, Sam just reminded me and l thought I had done that early, my bad.. I just called Duncan today and left him a voice message asking him to give me the cards sku number and the name, just don't remember the name of the cards but he said they are updated versions with many input and output channels that can give complete cnc setup that the c11 can't he should call me back tomorrow and l will get back to you with the info. l am going to slow with my build.. is it possible that you make a drawing digram showing the wiring :) l love your setup but scare to wire anything wrong ! thank you for all of the great info Oz
+Ozy Ozy Oh sorry, I didn't mean to make more work for you. I figure he has more cards that will allow or many more inputs, maybe like a smooth stepper that is USB or LAN. Don't worry about it taking a long time, I think my mill conversion took something like 8 months :/
What's your opinion on the ballscrews and ballnuts you purchased? I've CAD'd up the CNC conversion of a different similar size lathe and used parts from Misumi in the design. The cost difference between those and the ones you used is pretty substantial.
+Kent A. Vander Velden My source for ballscrews was the same for my mill, which is why I went with them again. C7 are pretty decent, and if you can get rid of all your backlash on the rest of the machine I think you can reasonably assume .002 and better results. The last test I did on my mill was only out .002" over a 4" diameter circle, so I was pretty pleased. What's the price of the Misumi's?
+russtuff Roughly from Misumi, $500 for the ballnut-ballscrew set (machined to spec.) and then another $200 for the end supports, so $700 per axis! The crossfeed is a much smaller ballscrew, but it's the same price as the much larger longitudinal ballscrew. I was very intrigued that your source will machine the ballscrew to spec. I'll investigate your source more as my conversation is for education more than anything else. Was the 4" circle test a cutting test? If so, perhaps the .002" error could mostly be attributed to flexing in the tool and machine?
+Kent A. Vander Velden Whoa, that's way more than I would be willing to spend on a machine of this size. If this were some high-end lathe, maybe. I think my custom made 1204 screw was $70 shipped from China, with bearing blocks and the coupler included. No it was a light engraving test, and honestly I was shocked at the result. Maybe it was .004" over 4"..... i can't remember, but either way it was well within what I expected for a machine of this caliber (aka: hobby grade).
Hey Russ - I'm curious about the stepper drivers. Do the drivers build up significant heat, or do they run fairly cool? I'm thinking about an enclosure for my mill electronics, and I'm wondering if I'm going to need active cooling.
+Paul Frieden No I have never really noticed mine getting warm at all, probably due to the large heatsink over the whole back of the driver. That said, I have always run an exhaust fan (dual 80mm). On my new enclosure I switched those to 80mm intake and 80mm exhaust (same fans actually), and I expect it's going to be more than enough for the whole box.
Is a 3 Phase motor necessary, the Grizzly model G0752 comes with a variable speed (1hp) at a purchase price of $2000+, or is it still better in the long run to get the g0602 and change to a 3 phase variable speed. Currently, the G0602 is $1500+ and after purchasing a Leeson 1hp 3phase ($240) and a VFD ($140) you are close to the price point of the G0752. Any comment, please?
Do you know of an alternative to the "Speed Measure Sensor Module" that will work with your conversion design? Amazon is out of stock with no restocking date.
+George Gibeau Also - the Relay Board link in your BOM is dead. Thanks for the great videos - looking forward to doing my conversion (plus this lathe is on sale at Grizzly for $1,150)
+George Gibeau I had a feeling that was going to be a problem. The cnc4pc c3 index pulse cards will work fine, and that is the only one I am actually using right now. Since LinuxCNC actually prefers 2-3 sensors, I intend to try doing it all on an Arduino at some point, I just haven't gotten to it yet.
eehaww just seconds a go paid for the motors, the drivers and the 48v power supply!! don't know what to do with my previous 36 v power supply that I ordered A week ago:( ouch was $35 maybe returned to china -#####%$#@!& hmmmmm my c10 and the c6 will go back tomorrow for the upgrade to c11gs waiting for duncan to call me and give me the name of the new expensive boards that he was talking about last time, my bad; l didn't write them down, l was driving to frys food store when he called me(: Without your videos we will never get into that step sir thank you! Oz
+russtuff good morning, just wanted to ask you if you don't mind send me your bellscrews drawings for both axis, I know you don't want to give your drawings in case if they are different, but I just want to compare my drawing with your drawing to make sure I am on the right path :) Sorry for my so many questions, but hey without your guys I will never get my machine running! my email : sumer_art@yahoo.com my C11gs is on its way :) but don't know where to buy the c3 pules index card sounds like hard to find? now the speed measure module not in the amazon ! is there any other vendor to buy it from? again thank you for all the videos! Oz
I think I only have drawings for the X, but I may have the total dimension written down for the Z. I'll have to check. The X drawing is on my grabcad account too I believe. The C3 is also available from CNC4PC, and that other card does seem to have disappeared. I'm actually about to do some tests to find out if the C3 is actually even needed. It seems to just pass the signal to the BOB so I'm not sure why we all use it. With any luck I'll have that much sorted out before the weekend is over.
I like the way you are approaching this series, especially knowing that it's done and working already. I'll be following along closely. My mini mill conversion didn't go as smoothly as planned but I am making progress. A lathe will definitely be next though so this is great!
Thanks,

+Tom Zelickman (Inspiration Metalworks) Thanks Tom. This conversion wasn't the smoothest easy, but it's finally done (whew).

I want to build both f your CNC conversions, but for the moment I don't have room for them. I'll watch anyway, as it's fascinating and the info is adaptable to something I do gave room for (almost!)...a mini mill CNC. When I can arrange for more ship space, I'll be watching again!
Thanks!

+BigMjolnir Cool! Let me know when you get there and I am happy to help with any questions you have come up.
+russtuff You are a generous man! Thank you for the offer. Don't hold your breath though...it could be a while. Or not...we'll see. I'm reconsidering the plans all the time...I'd *like* the larger mill, I just have to figure a way to fit it in. The cost difference is negligible enough that space needed is the main decision factor.
+BigMjolnir I understand that. If I were in the mood to do another conversion I'd go with the Bolton 45 this time. Much larger and heavier, but not quite as much detailed info online. That's why I went with my mill. Hoss' plans were super helpful.
+russtuff I saw the CharterOak Automation mill at a model show last spring. Definitely larger, and surprisingly inexpensive for the manual version. It's on sale at the moment since they are moving to larger quarters.
I'm definitely going to get Hoss' plans if I go the G0704 route.

I've ordered stuff from Automation Technologies, and they're good, but when I do a LinuxCNC conversion I order the stepper motors and drivers and the parallel I/O card as a bundle on eBay, usually from Longs Motor or Wantai. I like the low prices and the one stop shopping, and the quality is actually quite good. I believe it's comparable to Automation Technologies. Many people get combo driver cards, but I prefer one driver per motor. If I blow up a driver (hasn't happened yet), it's easy and cheap to replace a single driver. I usually have a spare ready to go, just in case.
That's a good price on a real electrical enclosure. I've been using powder coated steel shop cabinets with stainless doors from Seville Classics. They were available at Sam's Club, but they stopped carrying the one I used and I had to buy the last two from the manufacturer's website.
I LOL'd when you said you were originally considering upgrading from LinuxCNC to Mach. Bwa ha ha ha ha. Check out some of the conversational programming wizard add-ins for LinuxCNC. Not as pretty as the PathPilot extension of LinuxCNC from Tormach, but they generally get the job done. Hopefully, PathPilot threw down the gauntlet and the open source programmers working on LinuxCNC will pick up the gauntlet. Even if not, there are plenty of other ways to get G code into LinuxCNC. PyCam is one, although more for mills than lathes. For one off jobs, I like being able to have conversational programming on the machine. Barring that, a lot can be done with a little understanding of G code at the MDI screen.
There are a few other LinuxCNC installation videos on UA-cam, but they're mostly out of date, and I'm sure yours will be more thorough.

Is a 3 Phase motor necessary, the Grizzly model G0752 comes with a variable speed (1hp) at a purchase price of $2000+, or is it still better in the long run to get the g0602 and change to a 3 phase variable speed. Currently, the G0602 is $1500+ and after purchasing a Leeson 1hp 3phase ($240) and a VFD ($140) you are close to the price point of the G0752. Any comment, please?
No it isn't. If I were buying today, I would get the one that already has variable speed and save myself the extra hassle.
Do you know of an alternative to the "Speed Measure Sensor Module" that will work with your conversion design? Amazon is out of stock with no restocking date.
+George Gibeau Also - the Relay Board link in your BOM is dead.
Thanks for the great videos - looking forward to doing my conversion (plus this lathe is on sale at Grizzly for $1,150)
+George Gibeau I had a feeling that was going to be a problem. The cnc4pc c3 index pulse cards will work fine, and that is the only one I am actually using right now. Since LinuxCNC actually prefers 2-3 sensors, I intend to try doing it all on an Arduino at some point, I just haven't gotten to it yet.
+George Gibeau Thanks for letting me know.
eehaww
just seconds a go paid for the motors, the drivers and the 48v power supply!! don't know what to do with my previous 36 v power supply that I ordered A week ago:( ouch
was $35 maybe returned to china -#####%$#@!& hmmmmm
my c10 and the c6 will go back tomorrow for the upgrade to c11gs
waiting for duncan to call me and give me the name of the new expensive boards that he was talking about last time,
my bad; l didn't write them down, l was driving to frys food store when he called me(:
Without your videos we will never get into that step sir
thank you!

+Ozy Ozy Very cool. No worries at all :)

good morning,
just wanted to ask you if you don't mind send me your bellscrews drawings for both axis, I know you don't want to give your drawings in case if they are different, but I just want to compare my drawing with your drawing to make sure I am on the right path :)
Sorry for my so many questions, but hey without your guys I will never get my machine running!
my email : sumer_art@yahoo.com
my C11gs is on its way :) but don't know where to buy the c3 pules index card sounds like hard to find?
now the speed measure module not in the amazon ! is there any other vendor to buy it from?
again thank you for all the videos!
Oz
I think I only have drawings for the X, but I may have the total dimension written down for the Z. I'll have to check. The X drawing is on my grabcad account too I believe.
The C3 is also available from CNC4PC, and that other card does seem to have disappeared. I'm actually about to do some tests to find out if the C3 is actually even needed. It seems to just pass the signal to the BOB so I'm not sure why we all use it. With any luck I'll have that much sorted out before the weekend is over.
