HMS_0300_0A00_0001_0005: Force sensor 1 detected unexpected continuous force. The heatbed may be stuck, or the analog front end may be broken.
These error code below shows the same issue of different force sensor:
0300 0A00 0001 0005
0300 0B00 0001 0005
0300 0C00 0001 0005
When the hotbed is not moving and there is no force applied on the hotbed , the voltage signal from the force sensor should be 0 volt. If the voltage is not 0, then there must be something wrong. in our test , below are the reasons we have met:
remove stuffs in the bottom of the printer
lift the hotbed until it's height is near the same as the excess chute, and check if the build plate has touch the surface of the excess chute:
Check the rear edge of the build plate, to see if it is too close to the inner liner the the printer:
Clean the bottom of the printer, if the hotbed is near the bottom of the printer and has contact with the stuffs in the bottom initially, the homing process may get disrupted:
Retry the "Home" function and see if it can succeed, and see if this HMS error message disappears.
If not, then there might be some real hardware issues.
