Today, while doing some maintenance on the nozzle of my Mini the USB connection with Octoprint went down so I restarted the printer to make it reconnect. This happened before so I didn’t think anything of it. But now, my printer seems broken. G29 makes some effort, but never actually probes the washers. It turns out something is wrong with my Y-min and Z-min endstop sensors. When I move the extruder so that none of the switches should trigger, M119 gives me:
> M119 < Reporting endstop status < x_min: open < x_max: open < y_min: TRIGGERED < y_max: open < z_min: TRIGGERED < z_max: open
What I did so far:
- Tried reflashing firmware
- Opened electrical chassis to check end-stop connectors, all are tightly connected.
- Disconnected Y-min end-stop to see if I could force an open on Y-min
- Disconnected Z-min and Y-min connectors on RAMBo to see if I could trigger an open status
I can move Y only forward untill endstop hits Y-max and then won’t budge anymore. Y will move back and forth while homing Y (it moves a bit back on G28 Y0 in order to re-approach Y-max and then backs off again).
Have I fried my Z-min and Y-min RAMBo end-stop sensor logic?
