@dc42 Looking forward to doing something similar, is there any update on the Duet 3 with external drivers might be available? Or should I buy a Duet 3 mini with 3 1XD's?

@Sindarius WOW! I didn't expect that kind of response, and I think that looks great! Really appreciate the work that you are doing.

I am extremely excited to have a CNC focused release as I have a large CNC router just waiting for a Duet upgrade.

Besides making the font larger, the biggest issue I see is how unclear the Duet "machine movement" section is and how easy it is to click on wrong speed. For example the "Jogging" section in this UI is both smaller and easier to use/intuitively understand.

Thought I was crazy but am having the exact same problems. Worked great with RC7, seen it pause for 5-10 seconds three times with RC8.

@chrishamm Thanks you!

@chrishamm Shared elsewhere but here is the results of "sudo journalctl -u duetcontrolserver -en 100 --no-pager"
