Seems only .gcode file inside the download link? Or did I miss something?


Yes, this is the example file that demonstrates a limitation of the USB to serial communications and motion control between the front panel Raise Touch panel pcDuino sending the gcode line by line to the Marlin motion control firmware. The skirt option with curved corners is creating finely segmented gcode that exposes this limitation and leads to motion stuttering because the buffer and transfer rate of all those tiny segments is being reached.

[...]

We were asking for the .stl file was due to we were trying to debug the Brim short segments in ideaMaker and wanted to ask the origin .stl file to test whether our fix works or not.
We guess that the stuck problem is due to the serial port has limitations of data transfer in short time, and the root reason of this is the Brim has been sliced to be too many short segments. So we want to debug this problem as a slicing problem from ideaMaker.


Hi,
Back after being away for a few days.
The STL can be found here on Thingiverse:
https://www.thingiverse.com/thing:2741800

It's meant to be a first-layer calibration test for the whole bed. I've actually found printing these sorts of objects to be a lot more helpful WRT tuning and tramming the bed vs. most of the other techniques out there.

HTH,
Jetdillo

Tested with the model you shared with the beta version, the steps of Brim part have been reduced from 30,000+ to 3,000+.

Cool.
When do you expect that the Beta version will be available for testing ?

We are planning to release a new version before the end of the April. If you want to have Beta version to test first, please shoot me a PM.
