G2Core is basically GRBL on the SAM38X - I'm sure that it would compile for any ARM7 core.

I should spend some time and see.... the code is freely available, so any hiccups should be able to be nutted out.

How close is 32-bit GRBL? Last time I looked there was a resistance...

The Main GRBL developer(Not us) is holding the release date very quiet. It's been a while but do wonder if this is still making progress.

I've just received your Nano-ARM boards (all the way to Borneo from Postie-Plus Upper Hutt - yay!) and have a 'CNC V.4.0' 3-axis shield for the Nano.

I will run it up with a Nano-clone configured to 3.3V and see if it works OK. If all's good, will look to compile GRBL and/or G2Core for the SAMD21.

I'm so over Asian mail delivery times (not from China, inbound to the third-world jungle where we live) and am so looking forward to moving back to NZ after 20+ years... some post can take 2-3 months, which is an age when you're waiting for a component :(

The ability to drive to a shop and buy wire, solder, connectors... instead of waiting a month or six weeks for the mail. Assuming we can still do that?

I know NZ Post is expensive, but at least it's efficient and fast!
