hi there! , ive been having a lot of prime tower failure since i have my a1( december )
So ive decided to do a fist layer check print ( created a cube and morphed it into a 1 layer print over the whole bed )
Ive noticed a wierd area on the bed ( exactly where slicers put most of the prime tower )
its like if this spot was either to low or different heat? it always have the same discolored area also …
i always clean my plates with isopropyl 90% and also cleaned them with soap and water + isopropyl for these test …
It looks like you might have a bad heater unit in the bed or a bad thermistor. When I had my heatbed go bad, the actual bed temperature would go way higher than what it was set for.
Does your bed temperature reading fluctuate more than 1 degree while printing? Set the bed temp to 65C on the control panel and then watch what it does over time. If you have a thermal thermometer, look at what it reads in different parts of the bed. The heater unit is two U shaped coils, so heating will not be totally even.
now look clowsly at the test print where its circleed not so bad and by the box it so bad with flaws all over. i made a support tiket and waiting to get an answer
