Setting firmware retraction with Simplify3D slicer

This is the method I use, works great!

There is also the Retraction Script but I don't know what it does?

For $150 they really need to add native G10/G11 support.

Just hovering over the pane beneath "Retraction script" I get a pop up message which says "Custom G-Code that is included right before a retraction takes place". I only get this pop-up once, when I select that tab, then hover over the pane. Not sure what additional thing you would want to do before a retraction - there doesn't seem to be a way to undo it after an unretract.

Tell me about it - with the £GB falling off a cliff as it has done these last few weeks, $150 is no small amount of money.

Could you put the M207 line in there to allow for fine tuning for different material's without having to modify the Config files?
Doug.
p.s. need to construct a M207 for myself now so any tips gratefully received.

I constructed this M207 S2.2 R-0.1 F3600 T1200 Z0.075 done one test and second one is running and I can't believe the difference it has made more info and photo to follow of the current print (40x40x20 box 2mm floor 30mm diam hole with a 20mm pillar in the middle.)

Hi Doug,
I guess you could but it would be acted on before every retraction with no way to edit it if it's embedded in the gcode file. I'd have thought a better way might be just to run a test print or two with the material you want to tune, enter M207 through the DWC and observe the result - so you can do it "on the fly". That's how I set up retraction in any case. Once you have good values for that material, enter them into the start gcode and/or maybe create a process that uses that start script (haven't yet played around enough with S3D to know what's possible).
My M207 (for PLA at 195 deg C and with 250mm or so Bowden tubes) is M207 S1.5 F3000 where S is the retraction amount in mm and F is the feedrate in mm/min. You can also add an R parameter which is extra length on restart and a Z parameter which will give you Z lift. There is another thread on here somewhere about firmware retraction and I believe David has just added the ability to have a slower unretract speed and also a negative "R" value.

Yes He has and I have those params in my Start Script now and yes you can set up Processes for each Material in your Machine Profile so I have one for PLA (Which I haven't used for ages) ABS, PETG and HIPS so far must admit I am now starting to love PETG uses similar bad temps to PLA but higher hotend temps much closer to ABS so I think is a better material than PLA especially for parts that may need to have some protection against Heat such as those inside a heated enclosure or those that are in contach with parts that may get warm (such as effectors)
Doug
PETG is printed with bed at 70 hotend at 230?

Looks like setting a Z Lift in the M207 over rides the S3D Setting so have tweaked mine up to 0.75.
