Entering PID Tuning to Slic3r
Ok, so.
Entering a set of values to the start G-code in Slic3r.
Say I run a first layer at 210c, and the rest at 205c - will the tuning results be added for 205 or 210?
M301 P15.63 I1.18 D51.86 <--- My result of autotuning @ 210
And finally, where in the start code should it go?
M115 U3.0.9 ; tell printer latest fw version
M83 ; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G1 Y-3.0 F1000.0 ; go outside pritn area
Thanks guys...

Re: Entering PID Tuning to Slic3r
Set it as first command. It will work regardless of temperature as long as you used reasonable temperature for tuning.

Wow. Night and day after using this.

Re: Entering PID Tuning to Slic3r
missed something...what PID tuning are you doing and how?
Re: Entering PID Tuning to Slic3r
Temperature calibration for the hotend and heatbed. Mine wasnt giving me much grief, usually a slight 1-3 degree offset during prints (up and down fluctuation) but I decided to use the autotune feature and its working quite well. No more fluctuation and Ive confirmed this with heat sensors. My line of thinking a better tuned system creates less work and stress on it.
Best thing to do is watch Tom's video on it.

Re: Entering PID Tuning to Slic3r
PID tuning should be placed immediately following the Tool selection (T0 in the single filament model).

Re: Entering PID Tuning to Slic3r
I'm assuming you mean that if you are adding it to the firmware Peter? The code I listed is stock in the Prusa edition of Slic3r.
I'm content with it in the startcode until I get printer #2 and #3 so I have a working printer(s) in case of a mishap with flashing.

Re: Entering PID Tuning to Slic3r
Yeah, apologies, wrong again. You can specify the extruder in the M301 command. It's M92 (steps/mm) you have to specify after tool selection.
Just realised that M301 without an extruder value applies to all extruders. So you can put it anywhere in the start GCode.

Re: Entering PID Tuning to Slic3r
How much more stable are we talking for this. I have my printer in an enclosure now and the bed is rock solid, but the Hotend goes up and down by 3c in either direction. Not sure what affect that has on the print, but always like to know I am doing the best I can.
Re: Entering PID Tuning to Slic3r
without tuning, I would see +- 3* swings on the LCD during printing, there was constant oscillation.
with tuning I now see an occasional +-1* swing on the LCD during printing, generally when there is a switch from printing infill to printing full layers.
If I adjust hot-end temp during a print, say after the first layer, it now only drops 7* vs the 10*-12* I was seeing before.

Now running with a sock. Before PID tuning, the temps varied +- 6 degrees; not is is 10% of that.
