I’m experiencing some strange behavior after installing version 5.0.0 (BLTouch) that I didn’t with the stock firmware on my Duplicator i3 Plus V1 (monoprice maker select).
Description of behavior:
- I flashed ADVi3++ from the prebuilt binary (5.1)
- change bltouch offset to match the indiego mount (which I have)
- complete the sensor debugging process, and get OK for all wires.
- select ‘auto bed level’ and the X/Y homing completes as expected, but then the system remains motionless when Z axis homing would take place. After 10 seconds without any Z axis movement, the LCD displays a “Homing Error” message.
Things I’ve tried:
- Going to ‘Move’, where I can move the X/Y axes as expected, but am unable to move the Z axis.
- Inverting the white/black wires on the BLTouch
- removed the JST-XH I originally installed on the ZProbe for the BLTouch connector, and replaced it with direct solders
- Reflashing the mainboard firmware to the ADVi3++ non-BLT version, and reinstalling the Z-min switch to see if movement is restored (it isn’t)
- removing the Z axis motors from the couplers to see if there is any movement in the motors at all when selecting “move” (there isn’t)
- With the couplers removed, the Z axis motors resist any manual movement when plugged in, but are less resistant when “disable movement” has been selected, indicating that there is a connection.
- There is no visible damage or obviously blown resistors on the mainboard. The last print I made was two days ago, which was successful (before switching firmware from stock).
- I also installed “flexible” couplers at the same time that I upgraded to the ADVi3++ firmware, but as there isn’t any movement of the motors with the couplers removed, I don’t think that is what is causing this.
Any help in debugging this would be greatly appreciated!
