alpha5_prerelease

Note: As of the alpha4 version, Pleccer itself is based on PrusaSlicer, but to keep support for SuperSlicer going, this repo will be updated with new features backported from Pleccer. For multimaterial/-color support please view updates there.

SuperPleccer alpha5

A new update with some updated features for using arc infill. Arc recursion is in test stage and will be added later.
Changes are:

• This version is rebased on SuperSlicer 2.5.59.2 accidentally called "Arc fitting edition" :) but for having G2/G3 support as option. Also now has Arachne support.
• Arc infill and pedestal spirals have been slightly tweaked
• Bridges have been improved
• Support by default chooses more or less automatically, you will still need to manually add supports on long bridges and big overhangs
• An option for max overhang distance was set (default 2cm), overhang is then converted to bridging.
• Small tweaks to make it theoretically print more reliable, like smaller spacing and infill before perimeter printing on arc infills.

Github workflows don´t work anymore, and I can only build Linux atm. I will look into mac and windows when i have time.

I unfortunately have not been able to compile a working version for Mac. Github actions don't work and manual compilation doesnt work either. You can use the PrusaSlicer 2.6 based Pleccer, see the previous release.

Thanks to @ristisaa #14 we now have a working windows build!

Pleccer Alpha4-2 prerelease (added arc-over-infill fix)

Pleccer alpha4-2 prerelease

This is the first Pleccer version using PrusaSlicer (alpha4) as base.
It contains few color printing updates yet, but has a nice set of new features for printing overhangs.
Try it out with the new test models file.

--- ### Alpha 4-2
added a fix to not use arcs over internal bridge infill, so it doesn't arc on infill anymore, thanks for the info (saw it in the CNCKitchen review)
also added is the option under the selectbox to use painted-on supports only, so you can manually paint on supports or try autopaint-on.

Notable updates:

• Arc infill is much better working, printing now from the inner to outer ring always works right, skipping over holes now works fine. do try to avoid weird surfaced overhangs for now (better by recursion of arcs-> next version)
• Pedestal spiral infill works well, picks a single pedestal as start point at random, no plans for improving that since it works fine
• Quick overhang settings have been added: handy defaults for organic and grid infill (snug was left out, sorry, it was working badly with overhangs). Also a custom overhang margin setting can set % of overhang support compared to line width, which works when the default is disabled.
• Holes overhang setting: if overhangs contain holes they are detected and this setting gives them a overhang override. for now for the whole object so other overhangs with no holes on the object also get overridden, per surface support settings needed (-> next version)
• Lot's of small improvements like better decisions in path planning, bridge infill detection and fine-tuned thin details strategy.

The test file with default support settings

N.B. >>> Best set your support's 'Overhang threshold' on 32 (deg) if you are in need of supports otherwise below 10 but never on 0 (automatic, works also, but is way too much supportive).

N.B. >>> If using multipart STLs/3MFs make sure to click the 'split to objects' button ( 'O'-button middle top) before slicing to have the supports picked per-object instead of for the whole.

Next version, beta1, will have:

• Better holes strategy; holes now are supported by adding a overhang setting to the whole model, it can be modded to only apply it to the actual hole(s) instead
• Arc recursion; by recursing the arc of arc infill you can print long(er) or thin overhangs.
• Arc printing Gcode support (G2/G3); saves some data in gcode
• Mixed extruder additions are halfway built (hence not in this alpha):
  • a virtual 'mixing extruder' is added that lets you paint a color and will automatically create the right mixing gcode
  • palette picker that lets you quickly pick a color and paint with that
  • colorgrab to pick colors from your screen
• Colored 3mf support
• Wipe-into-Support option

Important notice for MAC users: The App won't run!!! but there is a solution

alpha3_prerelease

• Overhang printing has some really big improvements:
  • The Bridge detector now includes pedestal detection, it is used for from-central arc printing (see discussion alpha 3 anouncement)
  • Arc infill makes a lot less errors in path planning, it for me always prints in the right direction
  • Parameters of the bridge detector scoring are now changeable (see 'print settings' -> 'output options' -> 'bridge detection scoring'), change them and see if the detected bridge angles get better. This table is an optimization issue, I have to think hard to find a way to solve this with logic instead of making up 'magic numbers' like this, but for now it works pretty ok, and is improvabnle with some extra post-processing code later if i can't think of a fundamental improved way.
  • Added more lighting of the previews
  • Small improvements, speedups mostly

IMPORTANT NOTICE: this is the last version of the alpha-cycle and the last SuperSlicer-based Pleccer, I am moving to using PrusaSlicer as base for Pleccer, it offers some great features (like tree support, arachne, etc). It now might take a while for a new version (first beta) to come out though as I have a lot to do.

NOTICE: I've added a test model collection that should be printable, just make sure you set the flow rate to a lower value and set the bridge speed low enough.

alpha2_prerelease

• Arc overhang improvements - it now orientates well on almost all non-gapped overhangs and the path direction is correct (as long as it is a continous, non-gapped path).
• Next release will have a solution for gaps in the overhangs.

Alpha1 prerelease

Contains a first rough working infill type called 'arc infill' designed to print overhangs without support.

Sorry, no mac builds yet
