Auto Tune Heated Bed Pid

Jun 09, 2016 I finally got it to work, you have to heat your bed withing 10 degrees of your target temperature then run the pid autotune, then it will work, as long as you have the pid autotune enabled in your marlin code and that other option below it commented out you are good to go, try that and let me know if it worked for you, if you haven't already figured it out. Re: PID tuning heatbed fail, 'timeout'. When using a high infill I wait til the second layer and spritz some acetone with a needle just around the inside brim. That causes the print to anchor to the glass.

Since the board is set up from the factory for bang-bang control for the heatbed and not PWM/PID control, I don't think there is any tuning you can do for the bed without reflashing the firmware with settings for PID/PWM. PWM/PID cannot be used with an external mechanical relay, only a FET or some solid-state relays. If using the on-board FET, it should be possible to use PWM/PID but only with reflashed firmware.

If while heating up, there is massive temperature overshoot and/or a bad oscillation of temperature above and below the target temp, then yes, there is a problem that will need some tuning or redesign ( the bed thermistor may not be thermally connected to the bed well enough). Otherwise, don't worry about it.

I haven't had any issues with wild temperature swings. I have my bed set up so I can use it with 12v through the FET for lower temperatures or with a flip of a switch, powered by a 20V power supply through a relay.
