So like many other I come here out of frustration. My A1 has been down for weeks as I have been going back and forth with tech support, and to their credit they appear to be trying to help. Any time I run the auto bed leveling I have the extrusion force sensor error, HMS 0300 1800 0001 0003. I have also gotten a pop up window with error 0300-400c 153621.
The strange thing was that when I ran the calibration from the printer itself it ran all the way through. If I run a print without the bed leveling the print fails or looks terrible.
So far support has had me change the TH board, check the usb-c cable several times, and change the extruder unit all together. Still the problem persists. I don’t imagine this is a common occurrence but any help would be appreciated.
