Thanks, I have the Baldor Small drive, after looking at the document you linked. I think it is the encoder on the motor. I got up there and just played with the wiring, disconnecting and...

I purchased a 1997 VMC15XT. It was under power, everything worked, and all was well. Then I had it loaded up and moved it a few hundred miles and now having some spindle issues. The first few...
I would sure love some details on how that spindle worked out. I have a jian-ken iso30 spindle but once I realized the JGL-80 would slide into the PCNC1100 I've been eyeing it and considering that...
I have everything that bolts to the Z axis carriage. The motor, controller, spindle, etc. I have all of the original pulleys and belts and motor mounts as well as (currently installed) a 4700 RPM...
Did you wire you drivers directly to the mains? I've seen some people say that this should still go through a transformer, but I don't see what that should be the case.
Thanks for feedback, guys! I'm sold. Since the current limit goes all the way down to 2.X amps, I'm probably going to do all my machines this way in the future.
When I first started messing with this stuff and made my own CNC conversion for the HF mini mill I quickly learned that higher voltage would allow higher stepping speeds. When I later upgraded a...
No sir, just designed my system to allow a much larger pulley (and longer belt) and everything else in the spindle is stock.
Yeah, I was intentionally driving it hard to see how it handled it. Motor got warm but not hot.
Most of the time I'll be doing closer to 3mm depth of cut instead of 9, and on anything below...
Timelapse of the pulley machining. First, I turned this blank manually in the lathe. Bored the center to 12mm, then turned down an 8mm length to an OD of 19mm. The 19mm part of the blank was then...
And here is another youtube video that shows me validating the design with plastic printed parts. The lower half of the mount has been machined from aluminum but I printed the rest just to test it. ...
FWIW, here's a quick upload to YouTube. I was testing it with 6061T6 aluminum. SpeedTiger 6mm end mill, 9mm depth of cut and 500mm/min feed rate. It eats aluminum now. I was stuck with about...
I searched all over for how to get more RPMs from the PM-25. Lots of options, but I took the simple approach (Maybe simple should be in air quotes?) and made a larger pulley for the motor, a new...
