Simplify 3D settings Mk2/S MMU  

Re: Simplify 3D settings Mk2/S MMU

I have rewritten my starting script (Process/Scripts/Starting Script) for the MMU and it prints fine now:

M115 U3.0.12-RC1 ; tell printer latest fw version
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G1 Y-3.0 Z0.5 F1000.0 ; go outside printing area to Z 0.50mm
G1 X50.0 E80.0 F1000.0 ; extrude 80mm
G1 X160.0 E20.0 F1000.0 ; extrude 20mm
G1 Z0.200 F7200.000 ; go to Z 0.20
G1 X220.0 E13 F1000.0 ; extrude 13mm
G1 X240.0 E0 F1000.0 ; wipe
G1 E-2 F1000.0 ; retract 2mm

Before printing a file though, preheat using the Mk2/S menu, then select load filament using the menu.

Ending Script:

M104 S160 T0; set extruder to 160 deg
G1 X0 Y200; home X axis
M117 Please wait...; display text
M109 S160 T0; wait for 160 deg
G1 E-100; Retract filament 100 mm
M104 S0 ; turn off temperature
M140 S0 ; turn off heatbed
M107 ; turn off fan
M84 ; disable motors

Once I have found the right settings, I will upload some S3D print settings.
For now the only thing I changed is the retract settings: 2.00mm at 20mm/s.

Feel free to post your findings and successful settings for S3D!

Re: Simplify 3D settings Mk2/S MMU

This is very helpful. I am curious, though - why not set the temp in the starting gcode?

You can. And also the end GCode may need to be tweaked to unload cleanly.

Does the PR Post Processor now work with S3D?

You should be able to modify this as necessary for most slicers.

EDIT: I understand that S3D is not as yet supported by the post processor, so any S3D prints will be single-filament only.

Re: Simplify 3D settings Mk2/S MMU

Thanks for sharing your script edit guys....

I'm curious if anyone would be able to let me know how to setup the print in Simplify3D for a multi-material print if possible. I've gone through the slicer version, and it works pretty well.... But I am a simplify 3D guy, and ideally would like to get this running properly.

When I load the STL's in simplify 3d I can assign extruders by adding extruders, but the STL's do not snap together nicely like in slicer... Am I missing something? Or is this just not possible as of yet? The STL's look all separated when importing to Simplify 3D.

Any help would be greatly appreciated!

Re: Simplify 3D settings Mk2/S MMU

Oh I do hate repeating myself. You cannot do this at the moment as the post processor does not currently support S3d.

You have the choice of using Slic3r (which is actually a much better slicer than S3D) or wait until the post processor supports S3D.

There is one more choice (which I cannot really recommend at the moment and that is KISS with a third party post processor.

As for S3D, yes it does handle multiple STLs correctly when set up properly - and I have no idea how to do that.

Re: Simplify 3D settings Mk2/S MMU

Peter,

Would you mind explaining to me/us what exactly the post processor is? What is the issue with S3D at this time, if you know!! Just looking for some insight!! Thanks.

Peter,

Yeah, it's actually quite simple. You generate your GCode with the relevant tool changes etc and then pass that GCode through a post processor which adds the necessary GCode for the unload and load, including the wipe tower.

This is something that only PR Slic3r can do internally at the moment simply because that GCode is specific to this printer.

I have written a post-processor which works with KISS (has been working with KISS for nearly 6 months) and is currently undergoing further development to enable many more features including more filament types, preload compensation and variable height prints.

At this moment, anyone wanting to print multi-filament with the Mk2 has the option of using Slic3r or writing their own post-processor for their preferred slicer. I may make my post-processor available when the latest version of KISS is released.

Peter

P.S. I did post the GCode for a MM print on the Blockage Troubleshooting thread; you could download that and search for "MMPP" to see what code is added.

Re: Simplify 3D settings Mk2/S MMU

Perfect! Clear as the sky on a sunny day in the south!

Thanks for taking the time to explain. This is kind of what I thought but wanted to make sure I understood since I am getting asked about this in some of my groups.

Hans,

In the above gcode, where is the tool selection done? I'm now starting to look into understanding gcode better but I am trying to get multiple extruder selection working correctly primarily on the purge line.

Thanks,

Re: Simplify 3D settings Mk2/S MMU

Settings work great.

Still have some stringing going on even after changing retraction settings but overall getting better than what it was with Slic3r PE.

Re: Simplify 3D settings Mk2/S MMU

Can you please share some setting for Simplify for a single extruder mode?

Re: Simplify 3D settings Mk2/S MMU

Hi to all of you

I still struggle get that script to run. So when a print finishes the filament will be retracted at 160 °C by 100mm but in the starting script the 100mm are not being incl.
So just for my understanding do I have to feed/load the filament manually in addition to the "pre-configured" loading procedure?
I tried to set it up automatically but I failed.
Can anyone of you help?

Best Wishes
Dan

Re: Simplify 3D settings Mk2/S MMU

Sorry to bump an old thread, but I reckon it's better than creating a duplicate one.

Did anyone have success creating a profile for S3D to print Single Extruder mode for the ones that did the MMU?

Thanks in advance!

Cheers,

Pedro

Re: Simplify 3D settings Mk2/S MMU

Sorry for neglecting this thread for a while, I had to build my Mk2 back to original specs.
Right now I have it set up as MMU again, and will continue to improve the S3D profile.

I still cannot get the PVA support to work reliably on the MMU, so I have to use single material print and support for now, and for complex objects, the automated supports of Slic3r are sometimes impossible to remove. Thus the need for S3D and its custom support generation is still required.

I will update the start/end scripts soon.

Re: Simplify 3D settings Mk2/S MMU

😮 i must have altered some thing and now its not working properly (work in progress)

UPDATE Profile Simplify 3D settings Mk2/S MMU

Dear fellow Prusa MK2/S MultiMaterial users,

Here is my tried and tested FFF profile version 003 for using Simplify3D with the Prusa Mk2/S MMU.

Download the file via my Facebook page:

https://www.facebook.com/HJ3Dprints/

Please like my page if you found it useful!

Installation:
Please download, change extension to .fff, in Simplify3D go to File/Import FFF profile and select the file.

User manual:
Before printing, use the Prusa menu to Load filament for Extruder number 1 (left one).

Note:
Only the PLA profile is tested so far, will update when new materials are added.

Please try it and report your findings!

Note it still is a work in progress.
The resulting prints using Real PLA filament are beautiful using my Prusa, and the supports for the 0.20mm layer height are super easy to remove.

Happy printing, HJ3D
