Toploong plasma cutter

Problems and questions
1

Hi, I’ve purchased a toploong gantry cnc plasma cutter with I believe a dangling f2100k controller.

Unfortunately whatever I output from sheetcam my controller won’t read, we think we’ve narrowed it down to the fact that sheetcam turns out G90 code but the controller specifically wants G91.

Sheetal hq dont think a post-processor will sort but seem to think the controller can be set to read G90.

Anyone have any experience of this or can offer any advice?

Thanks, Ste

Try “Koike Plasma” post processor with a output file extension of .txt

Hello everyone,

I’m sharing a SheetCam post processor adapted for a portable Toploong F2100K / 2100K plasma CNC controller.

I had quite a few issues with the standard post processors: badly interpreted G02/G03 arcs, rapid moves sometimes showing up like cutting moves, and problems with the M08G04 command. After a lot of testing, the version that works best on my machine uses a very simple and conservative syntax:

  • G21, G90, G40

  • M07 for torch ON

  • M08 for torch OFF

  • M08 forced before every G00 rapid move

  • arcs converted into small G01 line segments

  • no comments in the G-code

  • output files in .txt format

The goal is to generate clean, readable, and safe G-code for the Toploong controller, which seems to be quite sensitive to some syntaxes.

Of course, please test first in simulation, dry run, or with a pen before doing any real plasma cutting.

On my machine, this version finally gives consistent toolpaths for holes, marking lines, and outside contours.

I’m sharing it in case it can help other Toploong F2100K users.

Hallo, habe die gleiche cnc Machine und schon viele postprozessoren versucht und modifiziert. Alles ohne Erfolg. Ich brauche ebenfalls einen Postprozessor für den F2100K Controller von toploong der G91 mode, G41 erfordert und kein F für G00, und max. 3dezimal plätze hat.
