I run Inkcut on Ubuntu 18.04
inkcut is installed as standalone (but also as inkscape extension does not work)

svg file generated via inkscape is loaded fine and generates a reasonable path to be cut

when I launch the cut via "send to device", the cut is bad.
apparently some some path are included (either in the compiling phase or in the communication phase).
As a matter of fact the blade hops to the origin in unwanted places (the blade is not lifted), cutting through the outlines.

Thanks for your help

I run Inkcut on Ubuntu 18.04 and I am working on a Roland CAMM-1 GS-24
I installed inkcut both as standalone and also as inkscape extension, but when i come to cutting neither works perfectly.
In the configuration it start working (not perfectly) if I select HPGL -Hewlett Packard Graphic Language - but when I select CAMM-GL - Roland's Graphic Language it gives error. So I use the HPGL.

On Inkcut, the Svg file generated via inkscape gets loaded fine and inkcut generates a reasonable path to be cut

When I launch the cut via "send to device", the cut is not matching with the preview and it is wrong.
Apparently some some extra path are included (either in the compiling phase or in the communication phase) and as a matter of facts the blade hops to the origin in unwanted places (going some times to the originX, sometimes to OriginY, sometimes both). In this hops, the blade is not lifted and it cutting through the outlines.

The only hint I found online is this one: viewtopic.php?t=4987&start=25 but I cannot locate the package (and that issue is from almost 10 years ago, it can be that the architecture of the software changed!).

Thanks for your help

Inkcut is a third-party extension, right? Have you asked in the place the author suggests for asking? (whereever you got it from, there may even be multiple sources).
