Sequence of Printing Multiple Parts

Sequence of Printing Multiple Parts

Postby inventabuild » 13 Feb 2016, 01:24

If I have three separate parts on the build platform is there a way to tell KISSlicer the order in which to print the parts? I'm working with the e3d cyclops hot end and would like to make my own extruder purge pillar so I can purge out the old color from the the hot end before printing the new color; hence I would like to tell KISSlicer to print the extruder purge pillar before going to print the part. How do I tell Kisslicer to print the purge pillar first?

Doesn't it print the parts in the order that they are loaded? I believe that when I have done a sequential print of multiple parts that it prints them in the order you loaded them - and sometimes I have not been able to get the parts printed in the order I want them to print no matter how much I spin parts and allow them to reposition. I wish it allowed drag and drop of individual models. But that is what I have seen from order.

Hi
If you want pillar for each part (whatever they are), manually add your own-designed-pillar to the 3D model, then export to stl, then in KS/Extruder Map : Set "Priority" by mesh

In KS, you could try or combine the following feature :
- Sequential print
- Extruder Map : Set "Priority" by mesh
- Add part one by one + Extruder Map +/- sequential : choose mesh you want or not to be printed

Thanks I'll try this and see how it goes.

Be aware, what i suggest are "ways to explore"...the Set Priority by mesh seems not to be "mature"

Hope Jonathan will fix it in next version.

Keep us inform of what you choose to do. (or by MP)

If you are interested, I have written a KISS Post-Processor for the Prusa i3 "original Mk2 with MM (4 filament) upgrade.

The PP supplied by PR has not worked with KISS, so I wrote my own which is currently working well.

Basically, it creates a "wipe tower" for filament changes, the width of which can be changed to vary the purge quantity.

Hello Peter, yes please post your Post Processor and let me know how to use it.

Also, I do a fair amount of dual extrusion prints and I like the e3d Cyclops hotend because it's a single nozzle dual extruder; hence no need to level two nozzles against each other.

The only big downside to the Cyclops is that if one side of the extruder is not used for a period of time while the model is being printed the idle side can start cooking the PLA filament that's sitting in the hot zone.

Is there a way to tell your wipe tower to wipe both colors in between layers so the idle side of the Cyclops will always extrude filament periodically to avoid cooking the PLA? In this scenario, the extruder that's not going to be used next on a layer is the one that needs to be wiped first.

Thanks,

Mitch

Hi Mitch

Apologies, I don't come here too often; spend most of my time on the Prusa forums...

First a picture of the Prusa with quad upgrade and the wipe tower during a print:

Note the single nozzle arrangement with filament multiplexer above the extruder. The motors are sitting on top of the frame.

The post processor will create the G-Code to unload the filament into cooling tubes. On reflection, I don't know if it will work for you, because the unload is 92mm and the filament tips need to be properly formed by the cooling tubes to be able to reload. It may be possible to change the PP code for you, but the problem is that I don't have that extruder to test it with.

Exactly why the Prusa system is so good; also that you don't lose build volume...

As mentioned the Prusa method withdraws the filament so there is no possibility of this happening.

Without a tool change, that is currently not going to happen; unfortunately it would require 2 additional tool changes per layer and would waste an awful lot of filament.

With the Prusa method, there are 2 downsides; the time taken to change filaments and the filament waste. I did a 4C print of Adalinda; the wipe tower weighed 6 times more than the model.

Let me have a look at the Cyclops and how it works; I will then see if I can amend the PP to work with it and to meet your requirements.

Hi Peter, thanks for offering to tackle the Cyclops with your Post Processor; however after plenty of trials and tribulations I believe that, with what we have in-house, the Chimeral two nozzle dual extruder is the way to go now. I can level the two nozzles of the Chimera against each other pretty good and w/ the Chimera there is no filament wasted purging out the old color. The Cyclops sometimes deposits a speck of the previous color on the print where it shouldn't be even after the previous color is supposedly purged out plus I need to worry about cooking the filament on the idle side if it's not used frequently enough.

I am also very interested in your Prusa filament multiplexer and will see if I can mod it to work w/ my TAZ 6's. Are the colors all clean on the print or do you sometimes get a speck of a previous color in the print where it shouldn't be? I realize there is a lot of material wasted w/ the mulitplexer when your post processor is driving it during the color change, but if I want more than two colors it sounds like it's a price I'll have to pay. I do not want to try to level more than two heads against each other like w/ a 3 or 4 head hot end.

Please post your post processor so I can try it with the Chimera.

Thank you

Mitch

...by the way what is the name of the print you're making in the picture? It looks interesting.
