5-axis gantry controller

[tobjy]

I am building a 5-axis gantry for laser cutting. The mechanics is going good so far, but I am struggling selecting a controller board and software. I want to get the electronics running before I build everything together.

Best choice so far seems to be grblHAL for the FYSETC S6 V2 board. The web-builder does however not allow me to select 5 axis, it is fixed to 3. Does anyone know why? Does the board not support true 5-axis synchronized movements? Or is it because none of the out-of-the-box kinematic models supports more than 3 axis?

At a first glance of the source code, it seems that only a few kinematic models are available "out-of-the-box". I suppose I will need to code my own kinematics, right?

The board definition file (not the board map) is incorrect, max. number of axes/motors is 6, FYI auto squaring is not supported (due to limit switch inputs not beeing assigned).

Does the board not support true 5-axis synchronized movements?

It supports up to 6 axes if configured for one motor per axis.

I suppose I will need to code my own kinematics, right?

If you need a different one than those already supported then yes.

Thank you very much for confirming that. If I ever complete this project, I will share the code, who knows, might help someone else.
God Jul och gott nytt år!

God Jul och gott nytt år!

Takk det samme!

I'll update the board definition file in the next commit.
