After resolving my eeprom vs firmware issue yesterday I wasn’t able to much testing aside from jogging around the router. All axis’s home fine and I can jog each axis around without issue. I can run Z up to 130mm and they stay in sync. I kick off a carve (that same cribbage board generated in Estlcam) from octoprint and the Z axis’s get out of sync. I can watch Z2 begin the drop for the drill operation and a second or two later Z1 starts to drop. This continues until Z 0 seems to have shifted down -5 or more. I end up killing it before it gets too whacked out.
What I’ve checked:
Verified all wiring correct
Checked couplers and verified threaded Z rods and motor shafts were well seated and the grub screws tight.
Thinking it might be a voltage issue increased from 800 to 900
Disconnected the USB to Pi/OctoPi and tried to cut from SD - same results.
Drivers do not get hot nor do the motors.
Ran the job with out the router attached and still had the same issue. I could see the Dewalt plate hitting the surface and lifting the Y carriages as the job ran on.
