So I have worked through the ATC setup, I have the drawbar working (cncdepot 40c) but I cannot get the tool rack to move, it stays extended. I have tightened and loosened the needle valves to no effect. Any ideas to troubleshoot this?
I had a similar issue and thanks to Eric I found that the ribbon wire connecting the air solenoid bank to the control board was a little loose at the control board. I just gave it a push with my thumb and all worked well since.
ok I figured it out I had to adjust the needle valves .
