Temperature/Heating issue #54

Closed 3dGriff closed 7 years ago

3dGriff commented 7 years ago

We are noticing an issue with the PID remaining stable as it approaches and reaches it's target temperature.

In some cases this fluctuation prevents the HYSTERESIS function in marlin from beginning the print, or in other words the printer is not able to verify a stable temperature during the thermal check, thus it does not begin.

My replication of this issue has not been able to connect it to anything within the firmware itself, I will be doing some repeatability testes to verify a few things.

I would like to see results from the Mentos_RC branch for the following.

I want to see if we generate a constant result, I'm trying to link this to a root issue, I'm leaning in the direction of hardware, however, I'm still not certain.

I will report my findings and results as they come in.

Closing issue due to inactivity. Issue resolved by adjusting both hysteresis and thermistor settings. A hardware issue was found on only one machine. Will reopen if it becomes an issue in the future.
