Thunar has a plugin that lets you create shares directly from the Thunar file manager, which is the default for XFCE4. No need to manipulate the smb.conf file. Unfortunately debian doesn't provide a package for this.

The thing is if you had of asked you would do have been advised on the limitations of software step generation. It's not a finding, it is something that is known. And I could have directed you on how run 7c81 firmware on a $40 spartan 6 dev board, or been directed to one of the other projects.

I fail how your last post explains what I questioned.

If you want to delve into industry standard, what ever that may mean, you'll have to realise that the RPi isn't certified for industrial applications.

Furthermore I'd like to see the reference to that quote. None of it makes sense. It would appear you chose the wrong hardware setup for for application. Did you realise max step rate was related to latency and therefore the base thread ?

I mean by that you need additional hardware to get good results. The Pi alone even the 5 cannot handle it is my finding and conclusion.

""I think this was mentioned in the instructions that the PREEMT linux kernel was compatible only, but not recommended as 'industry standard'.""

What do you mean by this ?

I guess you haven't seen this:

LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

After using two model of pi (4B and 5) I still get disappointing results. Even at slow printing speeds around 25mm/s there is layer shifting and unreliable motion throughout the operation. I believe now that pi + GPIO struggles to keep up with the pulse generation. Even though I am doing indexed printing (orienting the bed only between sections of printing, so no full 5 axis kinematics) My application is a 5 axis (3 + 2 tilting bed) 3d printer.

I think this was mentioned in the instructions that the PREEMT linux kernel was compatible only, but not recommended as 'industry standard'. Since I cant afford a Mesa FPGA card I am going for klipper on an Octopus board and try my best there. Thanks everyone for being super helpful. And if anyone is interested my 5 axis slicer is on Github, it is A Blender addon that works if you also have the Cura engine up and running. You would be able to slice more complicated models with overhang and printing it by rotating the bed (if you do have this kind of setup).
