It will home but Y will not move
Quote from Hegemone on September 19, 2018, 3:03 pmI just installed everything and once I power on and connect to lightburn I cannot issue Y movements. It just stutters and sounds blocked. If I hit the home button it homes just fine so the Y is functioning. I had to reverse the y stepper motor connection for proper homing but it did the same stutter in both orientations.
I am in the process of downloading CNCjs but was hoping I was just missing something simple.
Thanks for the help.

Doesnt explain while it will move smoothy when issued a home command? Could it be the stepper voltage is not set correctly and isnt enough to start the stepper correctly when a jogg command is issued?
I tried reseating the stepper driver. I did notice that the connector wiring is different on both my steppers? The X is wired red, blue, yellow, white while the y stepper is wired red, blue, white, yellow.
Thougths?

In one direction the Y moves just fine even with quick jogs but in Y- if i jog too quickly it grinds near the home point. I have checked the belt and its clear. Since it is better with the swapped driver I am thinking the voltage needs adjusted to drive the stepper correctly.
I loosend the y belt to reduce tension and that seemed to fix it. Yay for systematic troubleshooting. The old board must have been running a higher stepper voltage to overcome the higher tension.
Well I guess I am getting closer. But still not where I wanted to be. I really wanted this to
