i read this... and i decide to check my files.
then i saw i have no cambam.exe.config..
this could be a reason.

then i looked to the older releases but no can losd because links  are death.

a 0.9.8 version could help. but from where i can get it?

thanks

Hello

I still have the 0.98 installed on my Linux, I just copied the folders for system and software, If I well remember Linux do not need an installer and maybe this can work just by copying files ....

i think more and more its a raspberry issue... i use debian 12 with linuxcnc....

[hitchhiker]

i attached the debug from mono... its a horror.... i think the raspberry pi 4 cant handle all options that cambam give to us.......

i try later something... dxf svg import not working i found out.

so on a pi its not all working great but i am work on find solutions

possible using older mono runtime and all the stuff

[hitchhiker]

still doesnt work..... think raspberry cant handle cambam like we need...

[hitchhiker]

hi folks

i done many trys...

short... raspberry can handle cambam. But its limited.
Text creating doesnt work. DXF import not work.

I done : upgrade glibc up to the newest.. try different mono versions and try different os.. like latest ubuntu.. debian 8 to 12.

its everytime the same... cambam crash when create text or import dxf ...

but a workarround is:

Inkscape!
in Inkscape you can open dxf and all kind of formats.
You can create text.
then you can make a gcode output.
set tool to 0.000001mm and cut depth to 0.00001mm.set safeheight to 0.0mmm
save the gcode.

then open cambam and import the gcode.. now you have all in polylines.

if you change in inkscape tool to 0.0 or cut depth to 0.0 you dont get a output.

but with inkscape to gcode to cambam you can realy do everythink on the raspberry pi 4 and 5.

this workarround works out of the box direct.

for me it was important to get text and dxf into cambam on my pi.

on my pi i have linuxcnc with a mesa 7c81.
normaly i use cambam on a standart pc with linux or windows.. make my parts... put it on my network... load it in linuxcnc on the rasp and make chips.

sometimes its quicker to do all on the rasp...
3d parts i make in fusion hobby versions... but cambam is the tool what i use 80%.


on mormal pc with linux cambam works perfect.. only copy from 2 cambam sessions not working on linux.

i spend now 2 weeks with the raspberry issues.. waste of time i know.. but i found the workarround.

i hope i can help any dude who come to the same issue.

Hello

A guy on a french forum try CB on a RPI4 ... and same problem with the Text ...

For the DXF, be sure that your CamBam license is installed, if not, the soft act as if all 40 trial session have been used, and some features are disabled (like DXF import, plugins ...)
