Brilliant video, thank you. Now I understand why the various power buses are the way they are, flexibility.

Lots of people don't realize how useful 3D printers are. I can't wait to get my mill conversion done. I know the 3D printer will help me out as well. I have made so many useful things with my 3D printer.

i wish i was smart

@11:10 is just voodoo to me and i know a thing or two about pull-up & Pull-down. looks great!!

A few good ideas, but the case is to small in my opinion. The power supplies and CL-Stepper-Drivers are to near together. Also a plastic box is not really the best for handling high temperature of all aktiv components. And the most people I know about CNC are making the box to small, me too. One guy told me: make a plan what you need. Arrange all parts you need. Double the space and now you have the minimum.

This is truly amazing. I can only hope that I can build something like this one day. As a beginner in electronics, I wasn't able to understand why would you want a relay turning the contactor on? Using two push buttons can turn on the 120v contactor coil directly, isnt it? Or maybe I am wrong somewhere?

I like your 3d printed mount. It keeps things clean.

Very interesting. Nice work

Hello. Can you make the electrical project available?

What is the code for the Arizona CNC kit?

I don’t know of another drier video that is so packed full of useful information. Thank you for making this. Reminds me of the old UA-cam. You’re a legend

Wow.... my head is spinning. Nice job!😊

What size screw did you use for the axles?

Did you share your files anywhere on like Thingiverse or Grabcad? Very clever designs

I have same motors and mill as you. 12nm on the n34. Working on a similar 4th axis to 'practical renaissance' youtuber's setup. Seig lathe haleadstock. Subscribed.

Damnnn what happened? Was hoping too see it millong some parts.

What size allen wrench does that damn set screw take. I have millions of them but can't seem to find one that fits down in it. M5 or M6?

Quality stuff! Would you be willing to print off some more for your power supply mounting solution? I just got my G0704 and am sourcing the conversion parts.

Nice job, thanks for sharing! A concern I see is the estop shuts power to the stepper motor power supplies, my z axis would fall down perhaps onto the work in that case. Thanks again for sharing your videos.

I have the King Canada version of this machine, and this video was very helpful when I needed to remove the table from the base, so that I could break the machine down into smaller parts that I could carry down to my basement workshop. The two leadscrew brackets were definitely hard to remove. I used a mallet to strike a piece of wood, which I placed against the bracket. It took many hits, and some prying, but eventually got them off. I also ended up bending one of the locating pins, which I had to straighten before re-assembly. I don't know if the G0704 is the same, but the 4 locating pins for the brackets have threaded holes in the end, threaded M4.0x0.7. I was wondering if those threaded holes are intended to insert some kind of pin puller? Also, the locating pins seem to have a very slight taper, unless I was measuring wrong.

I watched the complete series. Great job (also the videos)! You should have way more views. One question; I wonder about the sizing of the power supplies. You use a separate PS for each motor. I was surprised about the low readings on the displays (max 2 amp I guess). Do you think the peak power is much higher? What is the rating of these power supplies and motors? And did you ever considered a shared PS? Again, thank you for taking the time to create this quality content.

If you have a lathe I bet you could mount the Y axis where the tool post goes then put an end mill in the chuck and hog out the material that way.

Do you happen to have the 3d print files or where to find them for some of the build? Anything would help!! Great work!

I recently purchased a "cousin" of the Grizzly G0704, the KIng Canada KC-20VS-2. The crate is still in my garage, and I will be partially dismantling it so that I can safely transport it down to my basement by myself. Your detailed disassembly videos are exactly what I need to separate the 265 lb machine into 3 or 4 manageable chunks. I was thinking the table, the headstock, and the column+base. Anyway, your photos and your explanation are really excellent. Thanks so much!

Just found your channel and Subscribed. Very nice machine.

Absolutely fantastic video, and one I am recommending to students. I have to ask, what was the holding torque (approx) for the test motors when you demonstrated losing steps? I am surprised that you could cause the larger closed loop motors to lose steps by hand!

Great hack! Thanks 🎉

Hello sir, thank you very much for sharing your videos, very well explained. Could you tell me where did you source your stepper motors? if you care to share a link , that'll be great

What die you do with the parts you remover i would like to purchase the three screws and nuts for x-y anes

Nylon would have been a good material for the gib.

Thank you SO MUCH for all the work you put into this very detailed explanation. God bless you.

Very nice. With the closed loop stepper motors, no dro scales required? Readouts are provided by the stepper encoder and step caloibrations?

This is SUPER helpful, thank you for the clear explanation!

hi, you made a really usefull video. Thanks, it helped me a lot

Is it necessary for the power supply to the motor drivers to be switched via contactor? Wouldn't the alarm input to the mesa card already tell the drivers to stop?

I had the same issue finding the driver for the chip to enavle the adapter. This helped me out a lot to do that search! Thanks for the advice!

Great video. Got you a new subscriber.

Update: My total USABLE cross travel is 7.25 inches. It would probably go to close to 7.5 if it weren't for the rear way-cover taking up space.

super useful information,thanks a lot for sharing 👍🙏

Bravo!

What is the model number and brand of those quick connectors between your base and the door?

Would you by chance have a link of the build setup you are using. A lot of folks I have seen do serial builds vs arduino. I think yours is a much more updated build.

Dear Jack of all trades, my name is Rohan and I'm copying your electronics enclsure for your CNC machine. I have the Australian equivalent to the G0704, which Iis called an Optimum BL20. I'm about ready to start wiring but I was hoping you might be willing to share your 3d print files for the db25 sub connector, two-storey relay board mount and stepper driver mount which is fantastic. I have a friend down the road who has solidworks if that is the format or just a 3d print file foe cura would suffice. Would you be willing, pretty please? Having the wiring panel easily removed is a great idea for future updates. Well done mate. Kind regards, Rohan

I use a bit of hot glue in such case. Comes off if needed with a drop of IPA

Great video, it helps a lot in understanding the 7i76e. This is the best resource for the 7i76e! Thank you

All of your videos are by far the best I’ve seen for G0704 conversion. Excellent content and video quality. Looking fwd to your next ‘lesson’! Ps: I’ve been building my conversion for almost 4 years with DMM servos and the acorn board. I fried the Z drive when I sent 48v to the 5v cable by not remembering I inverted the location of the plugs on the cabinet. Project is on hold for now, but I’m really interested in getting away from Windows computers and learning Linux system one day. Your control cabinet is a work of art...thanks for sharing your expertise!

Just wanted to see the mill run some G-Code. I'll be working on the limit switches and homing switches now. I want to get them installed before I make chips.

The next video with the G-Code running should be out in less than a week. No chips yet though. I want to put on limit switches before I make chips.

This reminds me of a funny and scary incident I heard regarding a hobbyist and his new CNC mill. He never installed the limit switches on his Z axis because he lost the mounting screws during assembly. He was anxious to take it for a spin, so he bypassed the missing switches. He started testing each axis and didn't realize he inadvertently set the machine for rapids just before testing the Z axis. In a split second, the milling head with the lead screw flew up from the column and punch a hole through his garage ceiling and fell back down on the mill. He was so traumatized he returned the machine at his expense and gave up on machining.

love the 3d printed gib idea!
