heatbed rebel FRW 3.2

[Pillccia]

Hello
I have a problem with the heatbed. after several autopid (m303) and data readings, save and reset.
insists on not functioning normally.
I went from megatronic where it worked, with duet I have a time / c ° error.
the plate is 8mm aluminum + 5mm glass.
My config.g is:

@Pillccia said in heatbed rebel FRW 3.2:

M500 ; salva eprom

Don't put M500 in config.g. It's only used immediately after tuning is finished to save the results. Send it from the console.

Only put M501 in config.g once.

@Phaedrux
i uploaded frw 2.05.
now the bed, and the rest, works, done autotuning of all the heaters, and the next step is to do the first test pieces, to see the last calibrations.

[deckingman]

@Pillccia There are no PID parameters anywhere in either your config.g or your config_overide.g files. You've got M307 B0 to disable bang-bang mode but you haven't put the result of the M303 tuning parameters in your config.g file, nor have you saved the result to config_overide (according to the information that you've posted).

[Pillccia]

Hello and thanks
But I didn't understand which line I have to write in config.g, M307 vp13,4 10950 d51,5?
Exact

[Phaedrux]

No.

In the console send M303 H0 S60 to tune the bed.
Wait for it to finish.
Then send M303 H1 S200 to tune the hotend.
Wait for it to finish.
Then send M500 to save the results.
Then add M501 to the end of config.g.

That's it.
