Heaters Unresponsive, no Errors

CCS86

Running 3.4.0.B7 on my Maestro, it is getting stuck where the heaters (bed and nozzle) will not respond to temp commands given through DWC or gcode. No errors shown, they just stay off.

I have tried cycling through active/standby/off

The behavior only seems to clear after power cycling the board.

I think this started after I ran the latest PID tuning. So, here are the before/after values in case it is related:

Bed:
Old:   M307 H0 R0.194 C896.8 D2.07 S1.00 V24.3
New: M307 H0 R0.190 K0.196:0.000 D2.03 E1.35 S1.00 B0 V24.3

Hotend:
Old:   M307 H1 R2.523 C231.0:134.5 D5.90 S1.00 V24.3
New: M307 H1 R2.324 K0.389:0.146 D3.76 E1.35 S1.00 B0 V24.3

Can you try with this beta release and retune the heaters?

@phaedrux Thanks!

Installed and run on the hotend

New values very similar: M307 H1 R2.459 K0.398:0.160 D3.91 E1.35 S1.00 B0 V24.3

I'll run the bed now, but that takes forever.

CCS86

Okay, bed finally done. Sheesh that takes a long time! 1 hour 13 minutes.

Warning: heater behaviour was not consistent during tuning
Auto tuning heater 0 completed after 3 idle and 25 tuning cycles in 4420 seconds. This heater needs the following M307 command:
 M307 H0 R0.190 K0.174:0.000 D1.95 E1.35 S1.00 B0
Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.

Old: M307 H0 R0.190 K0.196:0.000 D2.03 E1.35 S1.00 B0
New: M307 H0 R0.190 K0.174:0.000 D1.95 E1.35 S1.00 B0

Also, I noticed the hotend tuning produces a V parameter, but the bed tuning does not. Should I add it?

From the wiki - quote.........

"Vnnn VIN supply voltage at which the A parameter was calibrated (RepRapFirmware 1.20 and later). This allows the PID controller to compensate for changes in supply voltage. A value of zero disables compensation for changes in VIN voltage. Supply voltage compensation is applied to hot end heaters only, not to bed or chamber heaters."

That explains it!

Did it help the original problem?

We shall see. I'll report back after I get some time on it.

@phaedrux So far, so good. Thanks!
