Can someone do the honours and push 3.2.18 to the repo?
Pushed! We are beginning smoke tests today, and hope to release as our beta testing version assuming no critical issues are found in smoke tests.

Thanks for the push.

Sadly, 3.2.18 with Marlin 1.1.8.29 still has the CRC errors and print pauses as previously reported.

Code: Select all

On the Good News front, It's not yet failed (~2 hours in and still printing) as reported in T2379. This did happen three times to me with 3.2.17 and 1.1.8.27. I'm running the same print now and it's certainly got further than 3.2.17.

I opened a task against 3.2.19. CuraLE goes into an infinite loop when slicing (.stl file is attached to the task).

Looks like we had this one nailed down to 2 million + manifold errors in the object: https://code.alephobjects.com/T2387

This one is tricky, and we are looking into it. The model file will slice successfully with a 0.5mm nozzle, but has issues when adjusting line width to match a 0.35mm nozzle. We will continue to investigate! https://code.alephobjects.com/T2383

I printed a large object on my Taz 6 this weekend. It was a small tweak of an object I had printed several times before.
I'm using Cura 3.2.19 (it would help if I could copy and paste the info from the about window, but I can't even select it)

I found that Cura refused to slice the object claiming it was too big.
The object is 270 mm wide, and my build plate is 300mm square.
Cura settings for the Taz 6 claim the bed is 280mm square.
I changed the settings to 300 mm square, and cura was then able to slice the object, and showed the object in the center of the bed.
When printed, the object was not centered on the bed. It was 8.25 mm shifted to the right of center, and 12.25 shifted towards the back of the plate.
This is a problem because it limits the size of object I can print.

I did not find any offset settings in the cura software to let me correct for these offsets.
I believe the printer knows the correct location of the bed since it properly probes the four corners of the bed during the auto-leveling.
I did not notice any offset when printing smaller objects before I adjusted the settings, but then this would not have been as obvious with a smaller object.

The skirt is a necessary feature in order to prime the print head, but the skirt makes the object larger, and therefore limits the print size. It would be nice to have an alternate way to prime the print head. Suggestions for alternatives are: interrupt the skirt if it would go off the print bed, extrude plastic off the edge of the bed, and move the head onto the bed while extruding to prevent a glob of plastic stuck to the nozzle (I'd like this anyway as I'm always having to grab the plastic "drool" with tweezers as the print begins), Draw a few lines of plastic near one of the edges of the print bed to keep the messy initial lines away from the print.

I have an enhancement request. I'd like to see the ooze shield have an adjustable width in lines and a separate speed. Simplify3D has both of these parameters. IMO, a width of 2 lines and a slower speed make a more reliable ooze shield.

Another ooze shield enhancement would be minimum and maximum distance. If the outline of the part is complex, the ooze shield is complex and being only one line wide, corners are sometimes missed. With a minimum and maximum distance (and a smarter algorithm), the ooze shield could be straightened out and have a much better chance of the layers actually printing on top of each other.

I found that if I import an object, then rotate it 45 degrees, delete it, and import another object, if I then set the angle to 0, it rotates the object 45 degrees.
