Hey, took a look around, but I can't seem to find it. If it pops up I'll pass it your way. Sorry!

Was searching the forums for this same problem, solved mine, so maybe this will work for you too. Keling schematic says 5V to PUL+ and DIR+, and control wires to PUL- and DIR- (from breakout or...

Juuussst had a similar problem, turns out their schematics are crap. If you think about the optoisolating circuit, it's pretty much an LED, so the inputs operate like an LED. You supply the 5V, and...

Well.. Their attitude seemed to change the day after I posted here, so who knows.. Looks to me like another company manufactures some of their product, and they just rebrand it; which would explain...

Ok, just a follow up. They sent out a replacement driver and my missing 5VDC power source free of charge, they didn't even ask me to return the broken one. Satisfied enough to continue shopping...

Well, they must have found this thread. All of a sudden they're willing to replace the faulty driver. We'll see how it goes. I didn't want any future dealings with them, but I'm not going to crap...

Quick background, engineer, machine designer, hobby CNC guy. Had a problem with a stepper driver not working. Swapped out the driver with a working one I had to confirm wiring. When I asked them...

Ah, cool stuff. I ended up just making all the parts on another small mill I own (Dore Westbury), and my Taig lathe. I haven't bothered upgrading the motor or spindle bearings yet. I have some...

Hey, just finished an X1 conversion a few weeks back for running aluminum widgets and junk. Actually getting around 0.002" repeatability from the original acme leadscrews. Have you had any luck...

Hey, hate to give the whole "have you plugged it in" speech, but I know a lot of these MIC lasers are 220VAC, not 120VAC... Just a heads up, cheers :cheers:

Do you keep the ballscrew and guides greased? Honestly, I usually look for stuff on e-bay, haha. Most recirculating ball bearings allow for some degree of angular variance, I don't imagine those...

Yeah, if you're binding you're probably not parallel. Have a similar problem with an old Dore Westbury mill I converted to CNC, lost about half an inch on the Z axis because the leadscrew seems to...

Hey, were you still looking for linear bearings? I have 20(ish) Thompson 1" ID linear ball bearings. I have 1" shafting from NB as well; honestly just never got around to using it. Bought it, then...

Hey, day late and a dollar short, but I just finished converting my Dore Westbury Mk I to a CNC. You can use Kcam or Mach 3 for backlash compensation. I haven't cut anything yet, still calibrating,...

Hey, I was looking everywhere for these Vexta (Oriental Motor) stepper controller documents and couldn't find them. Now that I have them, I figure I'd share. Unfortunately the UD2115 PDF is over 3...
