After Micro swiss DD upgrade,Extruder skips steps

lui2004

@Veti i think i have solved it !
i have a all Metal hotend from micro swiss and it was recommended to increase temperatur 5-10°C so i have tested it with 222°C and i have no stringing just a little bit but its ok.

what i can print now to check if its all ok with my setup ?

Edit:

I have a 0.4 Nozzle which Extrusion Widht did i take ? in some how to and youtube Videos they say take EW: 0.45 another Video says take 0.48 Etrusion Widht, its a little bit confusing

@Veti thats the benchy

Can i make somrhing better ? This was printer with prusaslucer 2.3.0 alpha 2
If you need slicer config

i got this error with prusaslicer and duet wifi

Attempting to extrude with no tool selected
or
Setting temperature: no tool selected

i must heating up manual is there a fix ?

It's not super critical. Generally it's recommended to use a value somewhat larger than the nozzle orifice. You can let PrusaSlicer handle it entirely by setting the width to 0. It will likely end up around .48. You can adjust it manually as well. Smaller to get better detail or to fit 2 perimeters evenly into a thin wall. Going below nozzle width can help make supports easier to break apart.

Hi
I have made some modifications i want your opinion what i can make better

Your extrusion multiplier as configured in that screen shot is set to 0.4 for all move types (read the hover text to see how it's calculated) to let the slicer use it's default set the first number to 0 as well. Nothing wrong with 0.4 per se, especially on small detailed models, but going a bit above nozzle size as the default does (25% above I believe) will allow for stronger parts and maybe some reduced print times.

Your print speeds are also very conservative. You could likely double those speeds and have adequate quality.

The benchy appears slightly over extruded with some strings. Dropping your extrusion multiplier form 98% to 95% would likely help with that.

Look into enabling firmware retraction in the printer tab. Then you can more easily fine tune it with M207.

@Phaedrux inwill test tommorow

But can you help me with firmware retract? Is it not the same with setting in my slicer ? If i enable firmware retract do i need retraction in my slicer ?

Thanks

Phaedrux

For firmware retraction you tell the slicer you want to use firmware retraction. There's a check box in the printer tab. Then you configure how much retraction and how fast etc using the m207 command. That lets you modify the various parameters on the fly during a print to more easily test what works best. Then you can put that commabd in config.g to make it permanent. It also means you can modify it more easily for different filaments or if you find that you have too much or not enough in the middle of a print.

lui2004

@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.

lui2004

@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.

lui2004

i allready check use firmware retraction.

what is a good starting value for DD M207 ?

Macros are allready installed and i have PanelDue

@lui2004 said in After Micro swiss DD upgrade,Extruder skips steps:

Start with what you have set in the slicer

lui2004

@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.

lui2004

@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
