Heatbed temperature not constant
Hi I just found out the middle part of my heatbed temperature is 5-8 degree less than other area. Is this normal ? I have deep hole cased by the nozzle pushing down the heatbed one time and not sure if it breaks any track of the PCB heatbed.

Re: Heatbed temperature not constant
i don't think it will have broken the tracks - it may have delaminated, or pushed them apart, when hot
can you place a thin layer of aluminium on top of the pcb to spread the heat?
ok you will lose a little of your z height but it will allow better conduction across the whole area.
