Sorry, just re-read this.

I am assuming that this is regardless of the polarity I use with the voltage source on the complimentary coil. If the deflection of the needle goes negative, the...

Gerry, my bad, it was late! I meant the A+ A- B+ B- terminals on the drivers.

BBMNet, Thank you for the info! I do have an analog meter around here somewhere and I will certainly give it a try. ...

Ok great. Going to go with a 70v power supply and either the dm860t or am882 drivers that Gerry suggested. Can't seem to bring myself to rip parts off of my last build to try on this one now that I...

Thanks Craig! The d57cm31's are on my DIY machine that I just finished building. I believe you had actually suggested I use them in a different thread back when I was putting it together and they...

Thanks for the replies guys. Gerry, I do plan on running the current steppers for now as I am undecided if I want to keep this machine or flip it. I agree there is definitely no need for a 1600oz...

A couple pictures of the machine for reference

Hi guys,
After finally finishing a DIY build that has been running very well, I have been given an older vytek rebel 4'x8' machine and am going to start refurbishing it. The machine is a really...

@chrisinestes, I know this is an old thread, but I just picked a rebel up myself and was wondering if you have a source for the 75mm belts? Before I begin refurbishing this machine, I just want to...

Hi guys,
After finally finishing my DIY 54"x 65" router, I have now been offered what looks to be an old Vytek 4x8 rebel router for free! I wish I had this opportunity about 3 months ago before I...

Awesome, as always, thank you Craig.

So i have my wiring pretty much buttoned up and am about ready to test run but i have a bit of a problem. I need to get the machine up and running hopefully...

Also here is a picture of the machine coming along. Figured I ought to share it as a thanks for the help

Craig, thank you for the help as always. I decided to go with UCCNC software and the UC100 controller with a C11G all from cncforpc.

I have a quick question on my dm860t stepper drivers though....

As far as features, I guess the standard suite of software features with the ability to home my 2 y axis steppers to square my gantry. outputs for PWM spindle control would be nice, inputs for limit...

Hi guys,
I am trying to decide on a motion controller/BOB/software combination but the analysis paralysis got a hold on me! I am halfway through a 4'x6' build and I need to get my control stuff...

Also, I wanted to make sure this big steel top was flat and level, so I just dumped a gallon and a half of self leveling tabletop epoxy on it.....had to share a picture because it would make a sweet...

Sorry guys, i was away and left this thread hanging for a few days!

Thanks for the encouraging words Pete! Funny story, I chucked the lead screws in my drill and ran them up on my bench again. I...

Pete I didn't see your second to last post. I can certainly add to the gantry, I was just concerned about weight. But if you think that I should have more than enough torque to throw it around, I...

Pete,
It is this one that Craig had suggested.

Object reference not set to an instance of an object.

Also the 3060 t-slot I went with is 3"x6", not 30mm x 60mm.....I wasn't very clear. ...

Pete, you are absolutely right, I had pulled the trigger on ordering parts far too early. Being a personal machine that I am running for a hobby and some side jobs, I was making an attempt to keep...

So I am making progress on the build and figured I would at least share a few pics of the gantry coming together. It is probably going to be pushing 100 lbs, as I am at 70 lbs the way it is now with...

Ok I propose a compromise. The DM860T drivers with a 77v 1000watt Antek power supply

And to update to Gecko...

That is probably a good point Gerry. I was a little hesitant about maxing out the voltage of a driver. I will order the 72v instead.

Also having a bit of analysis paralysis over the drivers. Is...

Thank you for the explanation Craig! I will order the Antek power supply that Gerry is using today.

Peteeng, I ran the ballscrews laying horizontally on my workbench using the bearing blocks...

Also, how many amps of power should I shoot for? These are 6 amp steppers, I assume I do not need 24 amp worth of power supplies...but I am not sure what voltage the 6 amps is rated at.

@joeaverage thank you for all of your help! You guys are an incredible resource! I was able to get through to leadshine today and have ordered the D57cm31 steppers you had suggested.

Object...

Joeaverage. I can't seem to get pricing from that company, they have not emailed me back. What are the chances I can get a motor like this to run around 1200rpm?
...

Thanks Ger21, I am going to look into the leadshine drivers. I am try to find some low inductance steppers and probably move up to nema 34 in case I need the torque when changing ballscrews to...

Thank you for the reply! I was concerned that the setup was going to be slow after a bit of research and you have confirmed that for me. Any suggestions for a faster stepper/driver combination? Or...

Hi guys,
Currently building my second CNC router and was wondering if anyone could give me some input on this combination of stepper/driver kit and ballscrews.

My current build is going to be a...
