Thank you for answering, sorry for putting you through this headache, I looked at the "Jog Controller" and it is set at 100, in fact I changed it to 200 to see if it makes a difference , it didn't. I am stumped... I am using KL 6050 stepper drivers and steppers are Nema 23 torque of 570 oz in 36 volt power supply ...
I do use the "Shift plus the arrows to rapid, it is not anywhere the speed that you have on your lathe, I do use 36 volts and the repeat ability is very accurate, I have the steppers reduced 2 to one twice, before it turns the Ball Screw, maybe that slowed it down ? I set the MDI feed rate to 20 IMP and it doesn"t seem to go any faster, I have the acceleration and speed set to max before it goes wild.
+John Minasian Hi John that sounds about right 3 amps. I have them set for half current at idle. As a rule I power them off if it's going to be idle for more than a few min. They will get hot this is normal. Be safe Sam
I don't understand, the only thing different is my drivers, so I am ordering some exactly like yours. I can't get anything to happen. Everything comes on but no movement, looks so easy!!!
+CNC4XR7 I may have too much voltage to the drivers, I think these are only good to 24 volts, they don't say that anywhere but seems I saw it somewhere. I have 36 volts to them, I think they are kicking out due to overvoltage. That being the only obvious reason I think I will just get some better drivers and then see what happens.
+James Hopkins Ok Well Let me know if I can be of any help, Are you getting a red Fault led? if you send me a private message we can exchange emails Be Safe Sam
Well, since I last posted here I have found several issues with my system. be careful when you buy cables for your cnc control boards. Turns out my cable is bad, well, I say bad no signal on some of the pins. This could be correct for some functions but when you are working with these boards you need all the pins functioning. I knew it had to be something on my end. I am still going to change out the drivers with better ones like you used.
+CNC4XR7 still waiting on a new cable, and I am going to install the better drivers as well should know something more by the weekend, and new mill is on it way, shipped today! I'm excited!!
Hi Sam, I finally got my Hardinge lathe converted to CNC, everything works fine except the rapid is very slow, I have the speed set at maximum in " motor settings" is there a solution for this problem? I am using nema 23 steppers on the Z and X . would a larger stepper help ? say a nema 35?
+John Minasian Well what voltage ? 36. How are you checking hold shift and arrow. Key. That should give you rapid speed. Also check your jog speed. Tab button
+Ozy Ozy Hard to say my dial indicator only goes to .001 There is some deflection I would say maybe .0003 to .0005 The spec sheet from the Factory listed it at .01mm which I would confirm to be about right. For the stuff I do its fine.
+CNC4XR7 you did great job on this one! I love your CNC, I am soon will convert to CNC ! I am just thinking of getting the G4003 and then convert it next year to CNC but the PM 1236 is looks more quality but really don't matter since you convert to CNC any lathe will do all threads cutting and turning if it got the encoder and the right software!! thank you again for your quick replay! and please post more vidoes Oz
Thank you Oz I also looked at both of those lathes it's all about capacity the 4003 has the d1 spindle which I really liked. To be honest I didn't need the 12 inch and stripping all the things that made those manual lathes nice just seamed like a waste so I went with the 10 inch. Quick change gearbox not needed clutch spindle brake not needed etc. if I can be of help let me know.
Tippo jee set up a dial indicator and move the axis in one direction a measured distance then back say 1 " the indicator should read 1 " if not the difference is your back lash. Check my videos I measure my machine back lash so younger a idea
+CncObsession No This is a kit I made But it does take some of the Cleaver Ideas Billy came up with in his kit. If your interested in one of Billy's Kits you can find it Here: www.ebay.com/itm/Grizzly-G0602-G0752-10-X-22-LATHE-CNC-BALLSCREW-CONVERSION-KIT-/271966028312?hash=item3f52704218
I realized it was your own after watching a few more videos. I did see the similarities in Billy's kit as I have his G0704 kit ;-) Good job on your conversions.
+Radoslaw Jocz Thanks, Yeah I really could not understand why you would want radius mode but I figured it was a old school CNC thing since the G code runs from a Radi point of view. Not being a trained CNC machinist I do not know.
There are some fairly modern CNCs for example (Sinumerik840) that you can use X axis in radial mode or diameter mode depending on the code in the program but default should be always diameter mode on 2 axis lathes to avoid mistakes. Most of round parts are measured in this way that you get a diameter on cylindrical surfaces and most of the drawings are done in this way also. However sometimes on the drawings are seen radial incremental sizes (for example shoulder of flanges etc.) but it is easy to calculate diameter by given radius and it is better way to do so instead of mixing approaches in the program. I can say this, it is based on my experience. But the main reason to use radial measurements on the lathe is when you are using multi axis lathe with life tooling then you can for example mill and drill on the face of previously turned workpiece in the same way as on the vertical 3 axis milling machine so then radial axes are usually preferred. In this case XY axes are available (both radial) because tool can go also above and below center line by calling Y axis (and Z is depth as usual), otherwise there might be XC axes configuration in simpler machines. C axis is rotary axis of main spindle (lathe chuck) then you can do positioning of the spindle in 360 degrees or define XC (Cartesian) plane. It can be used for some simple milling and it is often used for drilling and tapping on particular PCDs or making flats or hex for bolts heads. On some more rigid lathes you can do also keyway slots it saves the time. So the principle is to use X as diameter when turning, but when milling on the lathe X should be usually radial.
+Radoslaw Jocz Well it does make sense the part will be the Diameter not radius and why do you want to have to do the math all the time. Thanks Be Safe, Sam
Great video! Thanks a lot for going over the electronics & Mach3 configuration in such great detail!!
Thanks I hope I didn't miss anything.
Another great tutorial. Now, make some chips. Can't wait to see you turn your first project.

Hi John, when you hit tab and pull up the jog controller is the jog speed set to 100%
Sam thanks for the good info, I wanted to know how many amps are you applying on your steppers, mine are getting warm at 3 amps.

hey James Yea those cables need to be Straight through cables You may have two way Ohm the pins and see. I have seen this before.

Hi, what font did you use for the G0602 CNC decal?
Sorry I have no Idea I purchased them off Ebay the listing had Fonts you could choose from.

How to input the backlash values in mach 3 turn?
Top Left Config? Backlash input values in here.
backlash distance in units. whats mean?
Tippo jee
Yes input your measured backlash there in mm or inch.
I run mach 3 in inch so I would enter a decimal value .0001 etc.
Ok sir. But how to find my backlash distance in units?
Tippo jee
set up a dial indicator and move the axis in one direction a measured distance then back say 1 " the indicator should read 1 " if not the difference is your back lash. Check my videos I measure my machine back lash so younger a idea

On 2 axis lathes defult X axis mode should be always diameter and usually there is no any reason to change it at any time.

Thanks for clearing that up, I don't want to pass on bad information. I'm a little more familiar now with the cnc lathe and Mach 3 lathe.
+CNC4XR7 I do not know much about Mach 3 system. I was saying only about general principles used in CNC and engineering industry.
+Radoslaw Jocz Well it does make sense the part will be the Diameter not radius and why do you want to have to do the math all the time. Thanks

What is inches?
Mach 3 is run in inches. But I can switch to mm but I prefer inches.
Hi sir,
I need mach3 turn ,8 station motorized turret configuration and wiring circuits then VB script . kinldy send to me sir..
Please wait
