Topic: slic3r retraction

what do you use for retraction settings on SD3? Still trying to get the problem with my top solid fills not being solid and having holes. I wonder if retraction could cause.

The SD3 default profile from Solidoodle team is 1.5mm retraction @150mm/s

I tried lowering to 1mm and 30mm/s (slic3r default) dont see much difference

My SD3:  Clear plexiglass case, case heater, X axis stabilizer, Z axis stabilizer, thumb screws, filament guide, heatsinks on all motors, extruder fan, controller fan, heatsinks on motherboard, Y rod pillow block, USB and Power on/off switch, fully calibrated including trimpot tuning. Am I missing anything?

Re: slic3r retraction

i have .40 nozzle on new SD3 i wonder if I set it to .35mm nozzle the top solid layers will not have holes in them

Re: slic3r retraction

Have you calibrated your extruder?

Re: slic3r retraction

Since retraction only occurs at the end of an extrusion session I doubt this would have any thing to do with solid layers having holes, the main settings affecting solids will be extrusion rates and flow multipliers.

Re: slic3r retraction

Yep everything is calibrated and lubed up. The only thing I haven't calibrated is the voltages on the chip.

The only reason I thought retraction might play a role Is because I'm also getting gaps between perimeters and infill especially around circles (yes did y belt calibration)

But can someone post their retraction settings with Slic3r and solidoodle anyway for me just to play it safe. Because the solidoodle profile settings were way different from slic3r defaults for retraction but I lost that profile.

Also just want to see what people are thinking works best for retraction. Using ABS by the way. Want community consensus..

It's definitely not retraction then... sounds more like temp being a fraction too low, and your multiplier needing to go up fractionally.

Can't even remember the default retraction... 75mm/s and 3mm's ? anyway - its not this based on your description... do a print, increase flowrate to 105% and pretty certain the issue will resolve itself...

Tried with that flow rate also tried up to 110. Does help with holes on solid layers but not the problem with infill touching perimeters. But only thing is, with flow at 100 I am getting Those nice .42mm single walls on the cube tests. Isnt that what I want for proper flow and not higher? But what I've Got is the .40 nozzle and not the .35 which I'm sure was used for that calibration guide on the wiki..so maybe I actually don't want .42 wall width?

.48 is what you want

thanks. Should we also be setting the widths in slicer to .48 in advanced instead of .42?

Re: slic3r retraction

interesting results with retraction at 2.5 like solidoodle defaults I get holes in the print but at 1.0 I'm getting blobbing some spots on the first layer.
