I am using m5 bonded to m3 as a second Z stepper driver. I removed the lines for the second extruder in the config file as directed by smoothie
#extruder.hotend2.step_pin 2.8 # Pin for extruder step signal
#extruder.hotend2.dir_pin 2.13 # Pin for extruder dir signal
#extruder.hotend2.en_pin 4.29 # Pin for extruder enable signal
I have made the jumper to connect the 2 driver circuits on the board. It worked when I tested it a while ago. I left it alone while I worked on the printer then came back to it and now it does not work. I installed default config file and entered this code ……
G1 E100 F1000
to operate the m5 alone without the jumper and now it does not work. I dont know if I have blown the driver or how to proceed as this printer is designed for dual z steppers.
The Epsilon or M5 stepper motor does have some power to it as it is locked up when the board is powered up and then the motor loosens when I turn off motors in the smoothie web control app.
