Doubt due to passage from 2.05.1 to 3.1.1

luc

@Phaedrux Hi, I loaded 3.1.1 and then the new config, home, etc ...... everything worked right at the first try! This is a satisfaction both for me and for you who have patiently supported me. Thank you again!

The PIDs remain to do and move the 3 Z motors but I will do it later when I have some free time.

In the meantime I ask what "Mode: FFF" means in DWC (top right)

I don't know if it was there before but I hadn't noticed.

FFF = fused filament fabrication, AKA filament 3D printing mode.

@luc, if you still have your config file (or config-override.g file if you were using it) from RRF2, then you can use the M307 parameters from that, instead of doing a new PID tune.

Unfortunately I agree that I have the following errors:

5/10/2020, 08:48:48 M98 Pconfig.g
HTTP is enabled on port 80
FTP is enabled on port 21
TELNET is disabled
Warning: Heater 0 appears to be over-powered. If left on at full power, its temperature is predicted to reach 365C
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 790C
Error: Heater 2 not found
Error: Heater 4 not found
Error: Heater 5 not found
Error: Heater 6 not found

On Heater 0 and 1 I think I understand what it is (maybe even PID to be redone) but for Heater 2-4-5 and 6 what should I check?

luc

ok ... i solved. It was because of the config.override. I sent an M500, the file updated and the "Heaters x not found" errors disappeared. It remains the "warnig Heater 1 but I should resolve with a new pid.

Here's what those warnings means.

@Phaedrux Hi, maybe I say something not exact but I'm always looking for a solution by character. There is a value in the PID M307 which indicates the power of the heating phase which by default is 100%. If you decrease example to 80%, could it no longer give the warning? It might take a little longer to heat up but would you have other problems?

Phaedrux

@luc You may not get the warning, but the warning is indicating what the temperature is predicted to reach during a failure condition where the heater is stuck at 100% power on with no control. So limiting the PWM value to 80% won't help in that failure case.

@Phaedrux Ok..... Only during a failure condition....
