After Micro swiss DD upgrade,Extruder skips steps

@Phaedrux ok now i have downloaded the retract model stl
i have install the macros

how i start now for firmware retraction ?

Phaedrux

Well you'll need to tell the slicer to use firmware retraction. That will insert a G10 or G11 command into the code file when a retraction is needed.

Then you'll need to configure your retraction settings with an M207 command. https://duet3d.dozuki.com/Wiki/Gcode#Section_M207_Set_retract_length

Use that to set the speed and distance of retraction and unretraction.

Then during the print you can send an M207 command to modify one of those parameters every few layers to see how it behaves.

@Phaedrux ok i will try it

do i need to uncheck retraction on prusaslicer ?

Phaedrux

In Prusa Slicer go to Printer Settings, general tab, and near the bottom check "use firmware retraction". Then slice your file.

Then you'll need to have a M207 command in your config.g to set the starting values.

This set of macros may help make the tuning easier, especially if you have a PanelDue.

i allready check use firmware retraction.

what is a good starting value for DD M207 ?

Macros are allready installed and i have PanelDue

Start with what you have set in the slicer

@Phaedrux

in the slicer i have 1.5 at 40mm

M207 S1.5 F2400 Z0.075 do i need Z ?

Phaedrux

Z is for Z hop. Leave it at 0 for starters. But if you ever want to use Z hop that's where you set the distance.

@Phaedrux ok thanks a lot

i still printing the retraction stl

lui2004

@Phaedrux @Veti printing the two towers for retraction test no filament comes ot the nozzle

Veti

what changes did you make since the last print where it worked

This post is deleted!

@Veti nothing special, finetuning temptower,retract settings
all seems fine but with the M207 i have problems

Veti

so without m207 its extruding again?

lui2004

@Veti yes with normal retractin from slicer all fine

with M207 no extrusion , it will print only the base and not the 2 towers for retracting test

Edit:

now i have see what cause that no filament come out.
after retract its during to much time to reload the filament
i dont know which parameter can set to solve it

@Phaedrux @Veti

i forgot to check '' use realtive E distances '' in the printer Settings, now it works.

do i need to go higher with my retract settings ?

at this moment i got this settings for firmware retractions:

M207 P0 S1.5 R0 F2100 T2100 Z0 ; Firmware Retraction

or i need to print the retractions stl and post pictures ?

thanks

Veti

start the print. if its stringing increase the retraction setting in the console while printing.

lui2004

@Veti ok

with which one i begin ? retraction Speed,distance ... ?

Veti

distance

lui2004

@Veti ok

right now i am at:

M98 P"0:/macros/Tuning/Report Current Retraction Settings.g"
Tool 0 retract/reprime: length 0.25/0.25mm, speed 35.0/35.0mm/sec, Z hop 0.00m

without stringing,is it good ?
