My LR2 when homing Z goes down, not up, which is bad since the endstops are installed for Zmax. Using cncjs, and manually instructing Z +5mm, causes the LR2 to go up. Z -5mm causes it to go down. X and Y move and home properly. I believe what I have set up is Ymin and Zmax endstops, with a single X endstop, and the Z touch plate hooked up to Zmin (not currently connected). So what am I missing? Do I need to rebuild the firmware with different configuration.h values?
Endstops are wired NC. M119 shows all endstops open:
> M119 Reporting endstop status x_min: open y_min: open y2_min: open z_max: open z2_max: open z_probe: open ok
I believe the steppers are wired as per the documentation:
|Motor |Driver |Endstop| |---|---|---| |X |X |Xmin| |Y1 |Y |Ymin| |Y2 |E0 |Ymax| |Z1 |Z |Zmax| |Z2 |E1 |Xmax|
Not sure how much this picture will help, but here is my cardboard :):
The LCD was working with this setup, but for some reason, it just started showing a blank blue screen. It has a number of always on white pixels. Maybe it went belly up. I bought it from Ryan over 5 years ago, and haven’t used it much.
