Hey Jody,
It's nice to see you're reply. But, OF COURSE I knew you would reply - as I know you're a fan of using Nano!
Are you STILL using Nano???
Too bad I screwed up the Subject line - it should have been "V4" and not "V$"! Duh...
The pic you showed - which was from controlling the 3DP via a PC and connecting to the IP address. I believe originally they had a Duet Knockoff board in the printers. However, I think they are now using True Duet Boards in the printers. Also, the control panel on the front of the 3DP - that is totally new!
As for Klipper - I am REALLY Sure they are using some version of that - and I thought Rob mentioned that in the Video. The creator of the 3DP - Nazar from Ukraine (and he now lives right near VM in SoCal) - he was showing me some CRAZY STUFF (before I left the co.) - where he was experimenting with pushing the 3DP to print SUPER FAST! And - it was NUTS To see!
So - not sure - but, I thought they WERE using some variant of Klipper. But, I don't know much more than that...
On a related note - I reached out to my buddy Rob - about the Video. We chatted online last night a little bit about that (as well as him moving into his own apartment). But, another reason I reached out - is cause he mentioned the potential of 5-Degree printing (you know - they show the bed swiveling around - thus it's READY for 5D printing). Well - he told me about these folks who have a new Slicer - which CAN Indeed do Non-Planar printing AND thus 5D printing.
