Hi Andrew
QcadCAM Version: 3.27.8.0
Build Date: Oct 6 2022
Revision: dea3962
Qt Version: 5.14.2
Architecture: x86_64
Compiler: gcc 5.4.0
OS: Linux Mint 20.3 x86_64
And
OS: Windows 10 Pro 64bit
This is a well welcomed feature in Qcad but I seem to be having trouble with it.. 
.
Iāve looked at the Help file but I need some guidance on the actual settings for tracing.
Below is an example from Inkscape v1.1 Appimage āI have used this for yearsā the Trace Bitmap settings are default values.. I tied default values in Qcad but could not achieve the desired result, I also tried setting to monochrome and played around with the thresholds but it shows a black screen and on an odd occasion locks upā¦ 
.
Any help will be much appreciated and Iām very happy that this feature will now be a part of Qcad 
.
Please see below sample screenshots, image file used āFace.pngā and dxf output from Inkscapeā¦
.
Cheers
John
PS FYI I had the same issue with previous Qcad Build 3.27.7
