Preheat error with ABS material


With ABS I can't heat at 100°C the heatbed, an error come before it's hot at around 95° after 5-10mn...

I tried to stick better the thermistor under the heatbed and it pass from 92° max to 95° max before error.

What's the problem ? the room temperature is around 20-21°C

Answer this question I have this problem too

Is this a good question?
