Show us your settings!
November 12, 2018 06:24PM
Hi all,

I'm interested in comparing settings. I've been having a right fight with the benchy and specifically the bow and rear corners. All tend to curl up. I had thought this was purely a cooling issue but when I tried faster processing settings the curl became much worse. So here are my critical config settings and the Slic3r settings:

M92 X87.489 Y87.489 Z400 E425.2 ; Set steps per mm
M566 X900 Y900 Z12 E800 ; Set maximum instantaneous speed changes (mm/min)
M203 X12000 Y12000 Z1200 E8000 ; Set maximum speeds (mm/min)
M201 X3000 Y3000 Z250 E500 ; Set accelerations (mm/s^2)
M906 X1000 Y1000 Z1000 E1000 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

Print Settings - Advanced
Default Extrusion width 0.55mm
First Layer: 265%
Perimeter: 0.50
(external) 0.50
Infill 0.575
(Solid) 0.53
(top solid) 0.53
Infill / perimiters overlap 75%
Bridge Flow ratio 1.05 (think I need to increase)

Print Settings - Speed
Perimieters 40
(small) 25
(external) 50%
Infill 55
(solid) 45
(top solid) 45
(gaps) 20
Bridges 25
Support Material 40

Nozzle Diameter = 0.5mm

These have given a PLA benchy with a slightly shiny finish. My next trial will be dropping to 0.15mm but increasing the speed. My thought here is that the smaller incremental addition of polymer may cool better than a big chunk.

Your settings are fairly similar to mine.

Do you have a layer cooling fan, that is the biggest improvement for curling after the first few layers.

For the first few layers, an enclosure & a decent build surface like PEI, PrintBite+ or LokBuild.

Yeah, got the stock part cooling fan mounted on the hotend but think the fan is naff. Just looking to mount a radial blower.

Benchies succesful at 0.2 and 0.3mm followed by a Hellboy head! Happy as. I'll update this with tje settings I used when I get a chance. Potential for speeding up the 0.2mm builds but 0.3 where at the point where I get extruder drive issues on a calibration extrusion into free space, so not pushing any further with speeds on that!

50mm radial fan mounted on the same bracket as the stock fan (holes drilled out to suit M3 bolts in situe) made all the difference.
