Just a little lost re: upgrading to 3.0 firmware.

OK, thanks.. I was trying to use M42, as specified in the documentation. I got everything else working now. Thanks a lot! This new system is a lot easier to wrap my head around

You can either use M950 Fn to create a fan port, then M106 Pn Sn to control it; or you can use M950 Pn to create a GpOut port, then use M42 Pn Sn to control it.

Using a fan port gives you a slider to control it in DWC, and options for direct thermostatic control. Using a GpOut port gives you neither of these, however you can still use the daemon.g file to have the LEDs change automatically in response to e.g. temperature or printer state.

Excellent info! Thanks! I've worked my way up to 3.1.1, and actually got 2 other people upgraded and configured now as well. Thanks for all of the help!

I realize it can be frustrating, when people like me who don't really have a solid grasp of the language are trying to learn. But I am learning, and I'm always willing to help others when I can, so I will pass the knowledge on to others at every opportunity..

And again, I understand this new naming convention a lot better. i like what you did. It was a bit confusing at first, but the more I read, the more it makes sense! Kudos!

I do have one small issue left, and I've put a day into it myself, without trying to bother you... I'm just stumped though.

My bed heater keeps erroring out.... I've pid tuned several times... It's just not liking it.. It reaches about 50 degrees, and then errors...

Here are My 2.5 values, which work fine in 2.5....

; Thermistors
M305 P0 T100000 B3950 R4700 H0 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
M305 P1 T100000 B4725 R4700 H0 L0 C7.06e-8 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction

M307 H0 A240.3 C608.7 D8.2 S1.00 V24.1 B0 ; Bed Heater
M307 H1 A270.7 C90.4 D6.7 B0 S1.0 ;Heater 1 model
M570 S360 ; Hot end may be a little slow to heat up so allow it 180 seconds
M143 S285

Here are My 3.1.1 values. Do you see any problem?
; Heaters
M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
;M307 H0 B0 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B4725 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
;M307 H1 B0 S1.00 ;Temp Comment out for experimentation ; disable bang-bang mode for heater and set PWM limit

M307 H0 A340.0 C140.0 D8.2 S1.00 V0.0 B0
M307 H1 A622.1 C260.5 D3.1 S1.00 V24.0 B0

Also, should bed be in PID mode? I've not used Bang Bang before.. Pid seems safer..

Thanks!

@Steve-Lynch No bother at all.

Yes PID for bed. Just say no to bang-bang.

What error message are you getting?

When you do the PID tune for the bed, are you saving the values to config-override with M500? Do you have M501 in config.g to load them? Or are you transferring them over to config.g?

[dc42]

Have you tried using the same M307 H0 command for RRF 3.1.1 that you used for RRF 2.05? The values shouldn't have changed significantly.

[Steve Lynch]

Trying now!

[Steve Lynch]

@Phaedrux

It's telling me that it's heating slower than expected... Trying my 2.5 variables now.

[Steve Lynch]

Well, son of a gun! The 2.5 variables work...

I wonder why the pid tune numbers are so different?

Is there any particular Pid tune regimen you recommend?

Preheat heaters? Nozzle to the bed? fans full on?

I try to do it with the "real world" environment it will be printing in. (e.g. fans on) is that the wrong train of thought?

That's how I do it too. Not sure why the values would be so different.

What are your 2.5 values?
