Well yeah it's not as solid as the voron, and at anything over say 1500mm/a acceleration it can get a bit bouncy (given I have a fair bit of weight cantilevered with the alloy plate so I kind of expected that) but I just did a full plate print, BLTouch did one probe in the centre and no compensation, and it was perfect across the whole plate, remove press print and exactly the same again...just need to work out some anti bounce but I like it a lot more

Check out the Hypercube Evolution design - uses 3030 extrusions with a few less parts to print - looks decent too, though a work in progress. There is a version with dual leadscrews on the Z axis (like the Voron) - this is the version I think I'll build.

I did see it, personally i don't see a need for the 3030 frame as I don't think that is the root of the flex issues that induce the ringing etc

I have seen somewhere another version somewhere or similar that uses 2040 that looked interesting also, i think it was on Reddit.

The motion axes moving at speed will still induce flex in the belts, bearings and motors on direction changes, i'm just focusing on getting the carbon fibre rods in when they arrive and a few other tweaks to hopefully lighten the X carriage and got an idea to get dual lead with a single motor without the giant belt running across the bottom of the printer also to stop the plate bounce...

Interested to compare and see results tho if you head down that path!

I was considering 3030 frame for a little PCB mill I am designing but I think i'll end up along the lines of 2040 and/or 2060.
