KISSlicer 1.6 Beta  

Re: KISSlicer 1.6 Beta

1. Way too hot. PR PLA at 0.15mm needs a max of 200 degrees.

2. Too much retraction - With some prints, and Preload enabled, you can set Destring to very low values.

The above combination always results in blockages, especially when there is a small gap between heat break and PTFE.

Note that I have 2 MMU printers; they each need different retraction settings (one requires destring 1mm less than the other). Much twiddling has to be carried out to get things right when using Preload.

Re: KISSlicer 1.6 Beta

- Style (15) Medium Fine
- no support
- Prusa I3 Quad (one Extr.)
- Matl PLA Prusa 215 210 Bed 55

All default parameters, no mods.

Whats wrong ?

Did you have a look on the provided profiles on the new KISS homepage? http://www.kisslicer.com/preconfigured-profiles.html
Peter has provided a pack of profiles including single extruder settings (thanks so much for this!) Maybe a bit tweaking is still necessary, but it is a good starting point (at least it was for me).

Re: KISSlicer 1.6 Beta

Peter,

I have a question about the settings you provided:
What is the idea behind setting the nozzle temp to 170°C when doing the calibration before the print? I was trying to print ABS yesterday with your settings (temp changed of course) and after the calibration it took a couple of seconds before filament has been extruded. I would guess that the material has not melted enough to be extruded properly

Re: KISSlicer 1.6 Beta

170c is for PLA to reduce dribbling during bed levelling, I suspect ABS initial temperature would need to be hotter but still below the normal ABS temperature... I dont use ABS so cant advise actual temperature

170 should be fine for most materials. Intention here is to ensure any blobs are soft enough to not interfere with the 9-point calibration whilst preventing oozing during that process.

It may be a simple matter of increasing the purge line at the start of the print. What I included in the start G-code was an approximation for the single-filament printer.

Re: KISSlicer 1.6 Beta

Thanks for your quick response.

I'll play around with a few parameters and see what works best.

P.s: The rest of the settings worked almost out of the box. Only changed the temperatures for my first Benchy printed in ABS and it came out pretty good.
I am currently running a 28h job with PLA and for now it looks very promising too...
So thanks again for your contribution...

Re: KISSlicer 1.6 Beta

I have another question about the speed settings in the provided profiles. The "Prusa i3 MK2-S Single" profile defines the following speed settings:

Fast:
20 >>> Perimeter
40 >>> Loops
50 >>> Solid Infill & Support
60 >>> Sparse Infill

The 'Precise' settings are 50% of the before mentioned values.
Has anybody tested if these values can be increased without any noticable impact on the print quality? Most of the models I sliced with KISS need quite more time compared to Slic3r gcodes... And I would expect our beloved printing buddy could handle a bit more (at least the provided Prusa Slic3r settings would raise these expectations...)

I am surprised that you find that KISS-sliced G-code is slower that that from Slic3r. Generally I have found it to be significantly quicker during testing.

The "Fast" speeds I am currently using are 60/75/70/90 with the "Precise" set to 10/20/25/30.

The slider at the bottom left of the style tab sets the print speed - I use 0 (fast) for models which do not require too much "quality" and with Preload dialled in, I use a range between 20 and 33.

You already mentioned that your KISS gcode is faster, that's why I was surprised as well and that's why I'm asking 😉
Just an example:I wanted to print this spool holder: https://www.thingiverse.com/thing:2634861
Slic3r produced gcode taking around 8 hours (predicted by Pronterface)
KISS predicted with the before mentioned speed settings (slider in the style tab set to 33) around 14 hours.

0.2 Layer height. Settings in KISS are mostly from the provided profiles (except some filament related changes)

The "Fast" speeds I am currently using are 60/75/70/90 with the "Precise" set to 10/20/25/30.

Thanks! That is indeed faster then in the provided profiles. Will definitly give this a try!

Re: KISSlicer 1.6 Beta

Next question: 😳
As far as I understood the the PreloadVE is the KISS feature of Linear Advance, correct?
Does it make sense to add the M900 command in the Material gcode section? Can I combine them or does it harm?!

Thanks again for your help.
