Geeetech a20m problems??

Post by DavidMalan » Fri Jul 16, 2021 4:34 pm

2 months or so ago I purchased a geeetech a20m with a bltouch sensor and I built the printer and installed the sensor. After I got it all assembled correctly I couldn't get the printer to work. I correctly installed to sensor and correctly flashed the firmware of my printer to enable the sensor. When I started my first print the printing head would just jam into the buildplate and won't stop doing that so I guessed there would be something wrong with the offset, I tried to fix that and I got it to stop only going down and putting A LOT of pressure onto the head into the buildplate. but now if I start a print the printer tries to level itself with the sensor and just keeps going up and up and never reach the buildplate. I HAVE NOT GOT THIS PRINTER TO WORK IN OVER 2 MONTHS and I couldn't get a refund, what am I supposed to do? Could anyone please suggest a fix? Even if I remove the sensor could I downgrade again and get the correct offset? Or is there something else wrong with this machine?omegle xender

check the wiring on the BL Touch, the wires should be like what are shown in this video:

you also need to make sure that the touch is lit up when the printer turns on.

From my experience, when the printer raises the z axis when trying to level the bed, it means the touch sensor has come unplugged or is wired incorrectly.
