Heatbed resistance 4 ohms - problem?
Hi,
I accidentally scratched the heatbed and was instructed by the support to touch it with acrylic paint. After first calibration the heatbed did not heated properly and I found the instructions to check the resistance. When I disassebled the cable holder I found out that one of the screws holding VCC or GND (I don't remember which) got loose and there was no contact).
I fixed the contact but while I was there I measured the resistance. It was 4 ohm between screws not 3.4. The prints come out fine but will the extra 0.6 of resistance cause any problems or is it within expected boundaries?

Hi Flying cog,
when measuring very low resistances meter leads often affect the value. this may be one of those instances.
