    The video shows that when I rotate the y axis both Z and Y move, but then I send a command to Z alone nothing moves but all of the steppers lock into place. I assume there is some sort of motor mapping (initial setup/configuration) that defines motor 1,2,3, and 4 as individual motors. I set one of these up before and I didnt run into this problem so I am scratching my head here.

    I made 3 posts and it says duplicate but nothing is showing up?

    Ok. I got everything wired up and I camnuaing Coolterm to test it out. X and y move as they should, z however does not rotate, but it does look like the brakes are on. Also the X axis locks but Y does not lock into place. Also when I send code to y it sounds like a small air leak (best I can describe) in the x and y axis steppers. To me that’s crazy. I tripped checked the wiring but it’s almost 3am and I’m super tired, I’ll.check again in the morning. Also z got hot.so I tired down the current. Z is half the size of z&y steppers

    That new board looks amazing. I guess ill have to build another project, one with 5axis to see what tje board cam do.

    So what should I do with the V9 board?

    Im all updated and want to confirm that my steppers are good to go. They are Dc5.5v 1.25a. I know there os a current adjustment for each stepper, but I didnt see the actual voltage window/recommendations. I have to assume that 5.5V is all good

    Lastly, whatever happened to the V9 project?

    Al right, I have my leadscrew installed and I have identified the center taps on each stepper motor. I verified the taps by measuring the resistance of the full coil 8.4 ohms and when intest the center tap I hey 1/2 the resistance. Whoo hoo, this project is moving forward at a snails pace. It took forever to find this unicorn of a lead screw and it was EXPENSIVE!

    Anyways, my tinyG has been sitting for years, should I FW update it before I get started or just give it a rip.

    Thanks, I did read about wiring them in such a way to only use 4 wires. I would already be testing everything, but I need to ID a lead screw and buy a new one as the one in this machine is worn out, the threats are sharp in the middle section of the lead screw. So I need to replace it and an anti backlash nut with triangle mounting face

    The controller in the link is exactly the controller that’s on the OX I am building. I don’t think I have configured the tinyG to work with the PWM controller correctly. I tried to load Ll of the settings art one time instead of a line at a time. Thanks for the link,, T

    Well I spoke to John Lauer (the ChiliPeppr originator) and he said you have to UAE trial and error to set up the steps correctly. Had said to peek at the Shapeoko setup and use that as a starting point.

    I am helping a friend finish us OX build with TinyG using Chilipeppr
