Question - Does the V6 board hardware support Bed PID setup, or will it cause overheating components?

[Trellian]

Hello, does anyone know if the V6 board hardware support Bed PID setup, or will it cause overheating components? I see this note in configuration.h:

    /**
     * PID Bed Heating
     *
     * If this option is enabled set PID constants below.
     * If this option is disabled, bang-bang will be used and BED_LIMIT_SWITCHING will enable hysteresis.
     *
     * The PID frequency will be the same as the extruder PWM.
     * If PID_dT is the default, and correct for the hardware/configuration, that means 7.689Hz,
     * which is fine for driving a square wave into a resistive load and does not significantly
     * impact FET heating. This also works fine on a Fotek SSR-10DA Solid State Relay into a 250W
     * heater. If your configuration is significantly different than this and you don't understand
     * the issues involved, don't use bed PID until someone else verifies that your hardware works.

I too have a Tronxy with the stock Chitu V6 Mobo. PID is all I use. I'm thankful I was told what it was, and how to calibrate. It does offer a more stable temperature setting. No issues with PID to date, I'm happy to report. I hope this helps! Cheers😁

Thank you! Can you confirm that you are using PID on the Bed, and not just the Hot-end?

I have three (3) XY-2 Pro Titan with V6 boards, running Marlin from this fork, and all three are using PID Bed. They all work fine and are run almost constantly at 80c.

@makmillion @lenigma1 thank you both!

I'll go one step further, and state that although it was some trial and error to find the needed pins, before a upgraded to a Duet 3 mini 5+ last week(night and day better than ChiTu boards!), I had a perfectly working PID for Bed, HotEnd, AND chamber via a 3rd thermocouple(wanted to add 2, one on either side of chamber... but couldnt find a 4th pin for thermo's...) and a 500 watt, high accuracy PTC heater and a couple 120mm x 25 Noctua's.

@lenigma1 Wow, well done! That sounds like an excellent setup :)

And I got my bed PID working great, thank you!
