That is a very nice solution though i think i'll stick to just using the T-Slot , and Iglidur. I have already purchased iglidur I150 as i wanted to try it out and would like to gain some experience with this material.Sorry to post again, just trying to get the hang of this forum.
And the 2in1 delta looks very interesting

The Lead screw are 8mm diameter, 2mm pitch, 8 start , which gives a lead of 16mm.

About the Z axis, i was actually in doubt if this design would be rigid enough, but it seems to be fine.
i was thinking about making it 3 point, but that would complicate the design quite a lot , and for now i'm satisfied with the result.

For now i'm using 120mm/sec for max speed of XY, but that's mainly due to the whining sound that i don't like.8 start, nice, they do look really aggressive, and geared up, sounds like the X-Y could move quite quickly in theory. What travel speed are you printing at? And what problems do you notice, ringing from mass/backlash or other?Quote

could probably go higher but for me it's plenty fast. 800mm/s for acc
I use 50mm/s for printing(PLA/PETG) for now and it seems that the biggest problem right now is some inconsistent layers.
This is freshly printed in Iglidur I150 on this printer, at 25mm/sec
The result is similar in PETG at 50mm/sec. i'll see if i can print the new slide in PETG tomorrow and post a pic.
i think it's more of a design choice along with cost, and i think i read something about oscillating with this type of Z-axis which can be a problem, but i have never used this type myself,Likewise. Mine turned out very stiff, and bed stiffness if more relative for 3d printers depositing liquid filament, just feel the stiffness of the end of the build plate on an Ultimaker or similar! I almost wonder if they purposefully build in some Z-flex so prints don't get torn off the bed when printing over a raised cooled section.Quote

so i really don't know.
I was thinking of a fixed bed printer when i started this one, but skipped the idea for simplicity. but definitely something i would like to try out.
