[FIXED] Major Retraction Bug In S3D

Mon Nov 05, 2018 7:53 pm

I was printing a peg-hole torture test and noticed my printer was stopping for what seemed like a long time at repeatable points. It turns out S3D was performing extremely slow retracts which made it seem like the printer was paused.

For example, S3D generated a bunch of E-1 F3 slow retracts at the edge retracts in the following picture:

Here's the gcode where the super slow retracts occur (notice the bunch of E-1.0000 F3):

Thanks for reporting this issue! What version of the software are you using to create this gcode output?

I wasn't able to reproduce the slowed speeds in Version 4.1.0. (Your factory file needs a special firmware file, which you haven't included here. Though that's likely not related.)

Thanks,

The retraction bug I found was in your previous version 4.0.1.

It looks like your team fixed it in the latest release 4.1 although it looks like there are other significant bugs in this new release, for example retraction while wipe appears broken (viewtopic.php?f=9&t=11703).

I can't go back to 4.0.1 because of the major retraction bug I found and mentioned above and I might need retraction while wipe to minimize stringing on some of my setups, but that feature is broken in 4.1.0 so you guys have me in a tough spot.

When are you planning an update to 4.1?

Now I found another major problem with V4.1. The following pic shows how V4.1 is not extruding and/or retracting properly on the perimeters:

V4.1 Perimeter Issues
Here's the same settings in V4.0.1 showing beautiful perimeters on the same part:
IMG_E9529[2].JPG
V4.0.1 Nice Perimeters On This Part
However as I mentioned at the beginning of this thread, V4.0.1 has major retraction issues and now I found out V4.1 also has a major extrusion and/or retraction issue.

S3D, YOU REALLY NEED TO GET YOUR BETA TESTING UNDER CONTROL. IT'S BEEN A LONG TIME SINCE YOU RELEASED AN UPDATE AND WHEN YOU FINALLY RELEASED ONE IT'S UNUSABLE.

UNFORTUNATELY, I WILL BE FORCED TO USE ANOTHER SLICER UNTIL YOU FIX YOUR MAJOR BUGS AND MAKE V4.1 USABLE.

If they made it perfect they would have no way to keep us coming back to create traffic on there site.

I was really hoping I don't have to go learn Cura since both my printers are custom. :x

I’m happy to state that both issues mentioned (retract and prime / retract during wipe movement) should be resolved now in the latest 4.1.1 release. Our team successfully tested several factory files from threads mentioning this issue (particularly retract during wipe movement issues in 4.1.0). You should not need to change any settings to have your prints working as expected in the latest version. Retract while wiping and correct retraction/prime values should both be working now in 4.1.1. This was just one of many improvements to the software. All of which are detailed on our Release Notes page.

Thank you for your help reporting this issue!
