The print head on my Lulzbot mini will not go down. The printer does not seem to realize this and keeps printing int he top position.
I had a bad filament jam and had to remove the print head and pull out the filament. Then I ran through several inches of cleaning filament. Everything seemed ok until I started to print and the print head would not go down.
Did you disconnect the Z endstops and if so, reconnect them properly?
If you open up the printer control window in cura (load an object, press print), when you press a Z down button, does it tell you anything in the side window where text appears (right side)?
I shorted out the Y endstop controller for the forward motion on my board cleaning the nozzle with metal and it required replacing the controller board. In my case, I would press the Y forward button and immediately see “Y endstop hit” followed by some number. Hopefully, it isn’t the same problem I had.
Hi I had same problem after maintained my extruder. I wonder how will thermistor and resistor shorted to heater block? My thermistor is working properly after I reassemble it.
