Firmware Retraction Tuning with Macros

fma

Thanks for sharing! Very usefull.

But you used the wrong param in the un-retract speed macros (F instead of T).

Phaedrux

@fma aww shoot! I was worried I'd make a mistake like that. That was a lot of files to create. I'll fix that up and replace the zip file.

Thanks for catching that.

EDIT: Fixed!

Thanks

4d. Warning Be careful with retraction distance. Using Bowden distances in a direct drive system will quickly pull your filament right out and possibly lead to a jam.

That will make my MK8 direct drive (extruder and hotend) into a bowden system according to your distinction. I have to use 3.5-5mm depending on the material to print.

Anyway also thanks from me for providing these!

Only one little thing: your zip file contains a lot of MacOS X specific files and directories. You might want to remove them. This will effectively half the number of files and size of all files.

@wilriker thanks for the catch on the Mac system files. They are of course not visible on my system. I just used the built in compressor. I'll use a tool with more options and update the file.

Do you think there are a lot more direct drive extruders with distances larger than those I provided? Would it be worthwhile to add more or would the average person know they needed longer? I'm always trying to keep the mind set of a beginner. Maybe a file named "if you need longer look in Bowden folder"

That's what I thought, so I also thought I just tell you.

Hard to tell. I would assume that most modern direct drive extruders would either use a V6 style hotend that cannot handle such long retractions very well. Also if someone uses an older model like a MK8 then they either have bought a super cheap Anet A8 (like me) or already know what they are doing for a long time.
I bought my printer based on an article in the Make Magazine where they also provided a list of things that definitely need to be replaced for safety reasons as well as some helpful upgrades. They also provided profile files for Cura that had 7mm retraction length with which I started.

Anyway, I think your idea about the file that tells people to look in the bowden directory in case they need longer retractions is a good middle ground.

@Phaedrux These are excellent! Well done and thank you for taking the time to share them!

I've updated the download link to include macros for tuning extruder acceleration, jerk, and travel acceleration.

Next up, macros for tuning XYZ acceleration and jerk.

Waiting for that

brunofporto

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

Phaedrux

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

@brunofporto Here you go.

@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/

kilop

@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

Phaedrux

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

kilop

@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 ...
