I've been playing with the PandaPi for a few months now. Finally received my Trianglelab Prusa MK3s BEAR kit and have been assembling it. Found some issues like 5V fans connected to 24V, not good. As well as I killed the bed thermistor input by connecting the power supply power fail singal by mistake. Fans are on order and I bet I can map another thermistor input to the bed.
My main issue now is I can't sensorless home. I can control the motors slightly, but when commanded to home, the motors just whine. If I use the "Easy" method, the motors will slam into the endstops. If I use my custom Configuration.h and Configuration_adv.h, which are built around Chris Warkocki's Prusa BEAR setup, but keeping PandaPi required settings, the motors whine and don't move then the printer errors with "Changing monitoring state from "Error: Printer halted. kill() called!" to "Offline (Error: Printer halted. kill() called!)""
So if someone can look at these configs and find any obvious errors, I'd appreciate it.
I think i had set mine to 700 for all steppers except the E which was set to 850. (on my MK2X)
Send: M906 Recv: X driver current: 500 Recv: Y driver current: 600 Recv: Z driver current: 700 Recv: E driver current: 800
Didn't see an Mcode for HOME Current:
Z_CURRENT_HOME (Z_CURRENT / 2 )
which current did you set?
It is probably too high or to low.
Start on the lower side and rise the current until it works
check your wiring (right selection of the coils)
