  1. Re: Stepper Motor always over-stepping even with low accel and speed

    For future reference for anyone that stumbles on this:
    Chinese TB6600 are total trash. Upgraded to $50 DQ542MA drivers and all my problems are solved. The TB6600 provides enough current (based on...
  2. Re: Stepper Motor always over-stepping even with low accel and speed

    I've found a few sources claiming GRBL does not support H-Bridge drivers. Bottom of this page:
    https://github.com/grbl/grbl/wiki/Connecting-Grbl#not-supported-h-bridge-drivers

    "NOT SUPPORTED:...

    The ticking sounds is coming from the motor as there is nothing connected other than a motor coupling that ways like 50 grams, and I've tried all 3 motors with the same effect. It's adding steps...
  4. Re: Stepper Motor always over-stepping even with low accel and speed

    I hope that's it. I guess I'll have to bite the bullet and get some of those. I just don't want to dish out another $150 before I know that is actually it.
  5. Stepper Motor always over-stepping even with low accel and speed

    I’m in the middle of building my CNC router. My electronics are just sitting on a desk here and I’ve been trying to get this to work for a few days. Even with no added resistance my motors seems to...
  6. Re: New build. Can't get Stepper Motor to Work with G-code Sender

    Figured it out. Arduino Mega 2560 does not use 2-4 and 5-7 pin for the axes. uses 24-26 and 30-32. Also, the Chinese drivers I got seemed to have the right color wires (blue, yellow, green, red) and...
  7. Re: New build. Can't get Stepper Motor to Work with G-code Sender

    I got it to do something by directing +5v from the Arduino to the DIR and PUL +5v terminals on the driver and the negatives from the driver to D6 and D7. There seems to be multiple ways to wire this...

  9. Re: First Build-Steel Frame-Cutting Area 2'3"x2'3"

    Hey, how did this turn out? You used cheap chinese drivers, right? Were those good enough to run those massive motors? I just got the drivers and will get the motors in a week. 270oz-in, though. Some...

    Re: Micro slot

    Hey, did you ever figure this out? I'm trying to cut micro fins for an aluminum heat sink and am considering the same thing.
  11. Optimal RPM and Leadscrew to run on Nema 23

    I'm planning to buy cheap Aliexpress crap, but is it really that bad? I'm planning to get:

    DC 36V 16.7A 600W psu (I...
  12. Re: Mods, Upgrades and Fixes Thread for 3020 and 3040 Desktop Mill/Router

    I have no idea if i should get one of these and heavily mod it or get a MillRight Carve King or even a MillRight M3 with some rigidity upgrades. I really just need something relatively fast and...
