setup simCNC/macOS/sheetcam plasma
Hello, here is a translation from French.
As an amateur user of plasma cutting, I purchased csmio/ip-s and the simCNC software. During startup I encountered some problems. Some resolved, some not.
- The manipulation described in “Python script editor” (press Ctrl + space simultaneously) did not work. Mac uses pre-registered keyboard shortcuts that must be disabled. System setting/keyboard/keyboard shortcut/input methods. and uncheck.
- I could not add cutting parameters to the THC “Cutting parameter editor” database. The py path did not work. I copied: profile/template_plasma_thc/scripts. In my new profiles. Since then I can add data.
- On the other hand, when I launch any Gcode, the speed that I enter in the THC settings is not taken into account. When FRO is at 1%, the feed is 1mm/min and when FRO is 100%, the feed is 100mm/min. I specify that when I activate my motors via key control or via manual input my motors run at the correct speed (6000mm/min).
- I use sheetcam to generate my Gcode. The feed rates must therefore be adjusted in simCNC. But I didn't find how to insert them into the g code to execute.
- And recently, I did some cutting tests on circular arc paths and it is impossible to open the g code. I don't know what it comes from either. I'll provide you with screenshots.
If you can enlighten me on these few points.
Thank you.

The thing with the circular arcs is probably due to the postprocessor that turns your CAM into GCode.

The plasma profile and the plasma screen are linked to each other by machine parameters and macros.
If you start creating your own plasma profile or deeply modifying the original plasma profile without knowing how it works, you will cause yourself unnecessary problems.
The cutting speed is configured on the plasma screen, and sent to a specially developed M3 macro located in the original plasma profile.
This specially developed M3 macro is responsible for informing simCNC at what speed to cut.
If you do not use the original plasma profile or you use your own M3 macro, simCNC does not know at what speed to cut and uses the default.
My advice, reinstall simCNC and use the original plasma profile, and everything will work.
