My mini seems to be ignoring both of the Y-axis end stops and one of the Z-axis end stops. I have verified with a multimeter that all switches are functioning correctly, and have verified that the switches are engaged when at the appropriate end of the axis.
The most obvious example is the Y axis. When sending the “home” command, the bed moves back, eventually hitting the end stop switch, yet it continues moving. At this point the printer starts to make a loud noise like the motor is skipping or grinding.
I’m not sure what to do about this since the switches are fine and are being engaged. It’s like the firmware is ignoring the switches or somehow a set of wires has been cut or unplugged.
What are my next steps?
