Firmware Retraction Tuning with Macros

brunofporto

Just using it now to tune.Thank you for this! Much easier!

@brunofporto I've got the other files mostly done. Will upload them after some testing.

@Phaedrux hi have a small question. should the g10 / 11 in the start script of simply3d or not. I'm now ready to fine-tune, and jpu marcos will certainly come in handy.

Phaedrux

@gideon I don't understand your question.

Have you configured Simplify3D to use firmware retraction? Perhaps using this method? http://thrinter.com/using-firmware-retraction-with-simplify3d/

@phaedrux I done this today but you need to add extra post processing to simplify 3d very important is to not to put 4.5mm (like in that tutorial ) but 4.5000

{REPLACE "G1 E-4.5000 F4800\n" "G10\n"}
{REPLACE "G1 E-0.0500 F4800\n" "G11\n"}
{REPLACE "G1 E-0.0500 F1440\n" "G11\n"}
{REPLACE "; inner perimeter" "; inner perimeter\nM204 S1500\nM205 X20 Y20"}
{REPLACE "; outer perimeter" "; outer perimeter\nM204 S500\nM205 X7 Y7"}
{REPLACE "; solid layer" "; solid layer\nM204 S700\nM205 X10 Y10"}
{REPLACE "; infill" "; infill\nM204 S1500\nM205 X15 Y15"}
{REPLACE "; support" "; support\nM204 S1500\nM205 X20 Y20"}

{STRIP "; postProcessing"}

and i also added some settings to start script for M207

M207 S4.5 F4800 Z0 ; set retraction length / speed

I'm just not sure why here is also M208 in this tutorial

M208 S0 F480 ; set retraction recover speed / adjustments

because for unretract speed is M207 Txxx

and then run some test prints with 4 small objects

and after using this scripts i ended up with
M207 S4.50 R-0.10 F6000 T4800 Z0.1 for Ziro White PLA

@kilop M208 sets unretract length in smoothie and Marlin apparently. Good catch.

@phaedrux

probably there could be also other option to change retraction generated by simplify 3d

in g-code tab tick m101 m102 m103 option
and in post process put this

{REPLACE "M101" "G11"}
{REPLACE "M103" "G10"}
{STRIP "M102"}

I will check this tomorrow at work

with that option will be easier to just copy and paste script to another profile

@phaedrux Can you point me to a thread or an article about how to set up firmware retraction ?

Phaedrux

@dakingofhearts2003 Well you need to enable it in your slicer and then have a command in your config.g to configure your retraction settings.

dakingofhearts2003

@phaedrux I understand that part. Understanding those macros and how to alter them is what im looking for ...

Phaedrux

@dakingofhearts2003 Retraction settings are configured with M207

dakingofhearts2003

@phaedrux I am having some serious issues that i don't think the retraction will help but i was going to do the retraction tuning anyway. Am i supposed to enable relative extrusion distances in the slicer ? And where do i start to deal with the issue of parts coming out smaller than they are supposed to. I can get them to print well but not dimensionally accurate...

Phaedrux

@dakingofhearts2003 Probably best to start a new thread to address your issues.

Is there are wipe while retracting function in firmware retraction aswell?

Phaedrux

@d0minik96 No there is no wipe function. Usually you'd be using pressure advance anyway and wipe/coast is not recommended when using pressure advance.
