Dumb question, how do I get rid of retraction all together its screwing with my prints hardcore… I’ve tried to get rid of it in slicer and repetier firmware (the newest) and it still wants to retract while printing. My nozzle dosnt ooze, so I don’t need it.
On the Printer tab, pick Extruder and set retraction to 0. Are you sure it is retraction bothering you or Z lift? Z lift is on the same screen. Retraction sucks up a little filament and is generally a good thing. It then extrudes the same amount after the move. Z lift picks up the extruder a little (tough on your Z system and should not be necessary unless you are not calibrated well or overextruding).
Ya no its the retract. in small infill areas it retracts and extrudes so fast that nothing comes out and your left with very little to no infill. Repetier host only lets me go to 1 on the retract setting I’ll try it again here in a min.
in slic3r it’s under Printer settings tab, -> Extruder 1 (or whatever number for multiple extruders)
note that there’s two retraction settings, one for normal printing(which is what you want here), and one for when the tool is disabled in multi extruder setups.
you want to set the length of the retraction to zero.
Try setting minimum travel after retract (mine is set for 2mm). If a move is less than this number retraction doesn’t occur. These are all on the same screen for Slic3r and Repetier should be just showing you the Slic3r settings. Mine takes 0.5 with no problem.
Ah thank you I knew it was in there somewhere.
If you’re retracting in infill areas, you need to probably check the option to not retract over infill. It’s less wear and tear on your extruder mechanism anyhow… It’s in the print settings, infill, “only retract when crossing perimeters”
A nozzle that doesnt ooze sounds like a hotend that hasnt been turned on.
@ThantiK thanks @Brian_Evans let me rephrase that, a very little bit not enough to cause strings or anything.
One more quick question, is it just me or does the new slicer process the perimiters of small holes differently now out side in instead of in to the outside? Or am I seeing things?
@Jeremy_G_WeisTek_Eng from the Slic3r changelog ( http://slic3r.org/releases/0.9.10b ): Concentric infill order was reversed so that smaller loops are printed at the end
The actual perimeters can be reversed with a single option.
@Thomas_Sanladerer thanks that explains it, its screwing with my circles. You know ware the option is?.
@Jeremy_G_WeisTek_Eng It’s in print settings > Layers and perimenters > External perimeters first ( in the bottom group). I don’t think the default behavior had changed, though…
@Thomas_Sanladerer found it just as you posted. Thanks you I’m going to try it and see.
