Question 4th axis

[walterwissmann]

Hello to all,

how is the status of the fourth axis?

Regards
Walter

No such code was ever merged to bCNC. If somebody develops this, i am willing to merge such feature under following circumstances:

• It will not break support of 3-axis controllers (guess this goes without saying)
• The GUI will be non-obtrusive (no need to hide it on 3-axis machines, just make it compact)
• The GUI will be prepared to support up to 6 axes in future

Also what kind of controller do you want to use for additional axes? As far as i know the stock GRBL does not support this...

For more see this label: more than 3 axes

As I read, G2Core runs 5 axes, I think 6 also (look Pocket NC) coordinated. You can add more axes but with latency drawbacks to coordinate movements

Yes, tinyg / g2core support is requested for very long time: #83

Hi Harvie,
I've used this for fork for extra axis, in windows 10.

It would be great if you could add the 4th axis in your version.
:)
There a few grbl forks for the mega, and they have several axis added in.
I liked the pin layout from https://github.com/LETARTARE/grblQ-Mega-4axes/tree/4axes/grbl
and i've used this with success.

6 axis support was already added in #1384

But there seems to be bug: #1426
