This is a continuation of my last thread but with a twist.
I can print 1 part (the same one from the other thread) at a time well but when I try and print multiples of the part cura slices several horizontal lines of filaments between the parts. I have printed multiple parts before with out any trouble, this one is new. It doesn’t matter if it is two or ten parts. This increases the print time by 5. Considering the bridging distances it wouldn’t print well like that.
I haven’t tried printing it yet, it’s not stringing… The lines show up in Cura and it shows them as part of the model which are not there in the CAD program.
Is there a way to export a jpeg out of Cura so I can post a picture of it?
The first one is a close up and shows the lines that Cura puts on
The second is a wide shot of the lines under the “print at once” function
The third is with “Print one at a time” function.
Individually it takes 14 Min. to print one. 2Hr and 10 Min to print them individually and over ten hr to print them with the lines, according to the Cura estimate. I haven’t printed any yet.
I tried opening it in Prusa but it wouldn’t accept STL files.
Back again and I did get it open in Prusa. The problem wasn’t there but the preview shows all kinds off holes in the part. I’m not familiar with Prusa is this normal.
It prints perfectly fine in Cura as an individual print but in Prusa it shows holes in the preview??? I’m not familiar with Prusa, maybe that is just the way it is?
Print time when 9 are printed individually is 2 hr 10 min. but printed as a batch of 9 it increase 5 fold, over 10 hrs, so the slicer is interpolating those lines as part of the print.
I have just started printing the 9 piece batch to see what happens so I will get back here when I have some results.
One suggestion, seeing as how it shows up in Prusa with holes and you see unexpected behavior overall. Import the file to PrusaSlicer, then see if there is a bang icon next to the file name in the settings window to the right. If so, the file needs repair. Click the bang icon, and Prusa will send it to the NetFab repair service online. I do this with every file that’s not already perfect and totally manifold. Once it’s repaired, export the plate as an STL and you should have a clean file to work with as normal in any slicer.
I don’t know what a bang icon is but I can’t see any kind of extra icon on Prusa.
As shown by the photo the lines are printed out not just travel lines. Printing them in the “one at a time” mode doesn’t do this.!!!
Might have to chalk this one up to Ripleys Believe it or not.
This is what it looks like in Cura here with travels turned off. it came up as a not watertight model but seemed to not be an issue I needed to fix.
did you duplicate the part in your cad program? you could have just brought on into Cura and had Cura duplicate it and arrange them on the build plate, it would save some time printing.
Looks to me like you’ve found an obscure bug in Cura - that happens only if you have some specific problem in the .stl file AND are printing in “all-at-once” mode (likely AND some other combination of parmeters). It should be fairly easy to find the travel motions in the gcode & observe that it’s running the extruder.
