    Hello, I have a machine with 32gb of RAM and an i5, QTdragon fails to visualize gcode files over 20-30mb. The RAM is not even loaded. What could be the problem and how to solve it? Instead of a program, a box within machine bounds is displayed.

Sorry for the late message. Unfortunately I had to give the project less priority. 
At the moment very busy with my full time work, my own company and graduating from my bachelor mechanical engineering next to a more than full-time job. 

I am slowly designing further on the mechanical part during my breaks. The hardware will be a pc that runs on plasmac in combination with a mesa board and a thcad. 

The drive will be a belt, I do not believe that this stretch is noticeable under the load of plasma cutting. Much cheaper and simpler in design than rack and pinion.

I think it is useful to change the title from
"Linuxcnc & the Rpasberry Pi"
to that 
"Linuxcnc & the Raspberry Pi"

Royka,
I hope you don't mind  linking to your 6.12 kernel from my how to document

you need to write your hal by hand. check the stiickies and start with an example config.

can you share the AXYZ_connect.hal file?
 

The opening post has all the files as attachments, just download and save them.

The hal_parport driver creates the pins & such and also talks directly to the parallel port hardware. I'm not sure if want you do is possible. I would imagine it would require a very special real time driver. I would also guess you wouldn't get any extra performance over using a parallel port as the step & direction timings would be created by the Linuxcnc software.
