Simplify3D retraction bug that can drive you nuts :)

Recommended Posts

This is bug that has been quite weird, but I think some users on S3D forum reported it, year ago, and still is unfixed and seems noone explained why or how to reproduce it.

So, here I go =)

When using multiple processes S3D thinks of each process as a new print, and their planner aligns them so they print 'right'. The problem with this is that he also thinks that when moving from process A to B the tool is different, so, he does a Tool Retraction Distance if you have wipe at the end of a loop, or Z change... Well, mostly, it does it correctly, but it forces a very very long retraction, that can end up adding blobs (because the head stays retracting more time) or it could, on Full Metal hotends, to clog.

So... If you use one hotend, just change the Tool Change to 0, distance 0, but don't touch the speed (or set is as the same your main settings use)

But if you use Two or more hotends, you will need to make your own toolchange retraction distance on the toolchange script area (not hard at all).

So to show my point, I just made made two prints one with this

And other with the values set to 0 (again, except the speed)

And as you can see, the retraction bug disappears

So, if you use S3D multiple process, and a single hotend, or two, and you want to enjoy the wonders of wipe, coasting, retract-while-wipe, etc.. You NEED to set the toolchange distance to 0 and if you use multiple hotends, make your own E- script for the tool change.

And, why this is important btw? Because the bug makes the whole print slower, and full of weird retraction distances. Check this Gcode compare, Left is bad, Right is ok. For Full metal hotend users, this is a very important thing to check.

Dude :|

Dont get me started on retraction problems.

Every damn software i tried to this very day has it.

Its either retracting or not retracting when you expect it.

I am assuming its because people who designed these software have crappy extruders that are not capable of handling lots of extrusions like my extruder does.

CURA

CRAFTWARE

REPETIER

Simplify3D a $150 or what ? *|

Kissliser

Slicer

Matter Control (a joke that uses OTHER slicer engines such as CURA and REPETIER because its own is garbage)

SliceCrafter (has no retraction option whats so ever)

just to name a few i tried.

I am tired of this. Wish i could program my own.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
