Hi folks,
have a look to attached contour.
If i choose a tool diameter of 1.5mm the toolpath makes a weird jump, if i increase to 1.505mm the toolpath is OK.
Any ideas on this ?

Re: CAM toolpath jumps in dependence of tool diameter
Thanks for your report. This problem has been fixed in the latest development version of QCAD/CAM. If you can indicate what platform you are on (Windows, MacOS, Linux, 32bit / 64bit), I can issue a snapshot release for you to try.

Hi Andrew,
currently i run here linux 64 bit.
cheers,

I've just sent you a download link for the latest QCAD/CAM snapshot release 3.19.2.6 for Linux 64bit via private message.
Re: CAM toolpath jumps in dependence of tool diameter
Hi Andrew,
thanks for that ... i tried and it works.
Here i have another problem ... don't know if this is 100% related to the last one. But there are different (even weird) toolpaths generated with the different versions.
3.19.2.6 3.19.2 Any ideas on this?

Re: CAM toolpath jumps in dependence of tool diameter
Unfortunately, these polylines are rather messy with duplicate and triple nodes and many virtually straight arc segments with huge radii. Presumably these are the result of exploding a text. Some fonts contain glyphs with such problems which makes them unsuitable for further processing without some clean up work.
I would recommend to either re-draw these polylines from scratch or clean them up using:
Draw > Polyline > Arc to Line Segments
Draw > Polyline > Normalize
Draw > Polyline > Simplify
Relocating the start point of a polyline helps with lead-in, lead-out problems.

QCAD is really cool !
