What's wrong with this settings?

[daftscience]

I've been able to make some decent prints with slic3r, but I'm having trouble with Kisslicer.

I think these settings cause the nozzle to crash into the print bed, and extrude (without moving) then it lifts up moves crashes and tries to extrude again. I'm not sure what's wrong :/


More info: My nozzle diameter is 0.6mm and i'm using 1.75mm filament.
*Edit: i messed up my pictures originally.

None of these settings cause crashes by default. The only value to manipulate your bed level is Offset Z in the Printer tab, which you have set to 0.

May it be, that you didn't set your printer height properly (Z=0 not being bed level) in your firmware and corrected this by setting an offset in slic3r?

Two advice when looking at your settings, which have nothing to do with your crashing problem, though help to perfect your prints later on:
- Have you measured the diameter of your filament exactly? Usually, it's not precisely 1.75 mm. By measuring 1 m of filament every 10 cm from two sides (usually, filament is slightly oval) using a caliper, you can average your diameter pretty close.
- For slow speeds (e.g. for calibration), 30 mm/min perimeter and 60 mm/min infill is pretty fast. Go for 10 mm/s for both, perimeter and infill. On the other hand, you can easily set the max speed for fast to 60 mm/min for perimeters or even higher. Before slicing, you can use the precision slider to set the wanted speed as a percentage in the range between the slow and the fast values.

Thanks, I'm going to calibrate the print height again tonight. But Z offset in slic3er is also set to 0. Thanks for the other tips though, I wasn't too sure what to enter for those speeds.

*edit: P.s. Thanks Highcooley for your build thread, it's been an excellent resource.

So, I re-calibrated and discovered I was originally wrong. What is happening is the printer moves to a position, extrudes for some time, stops extruding and then moves. After the move it will extrude some more, stop and move to another location.
