I am amazed at what I can get out the M90 design - if I go to a 32 bit board I am sure I could get sub 10 mins at quality
Mendel90 Sub 25 minute Benchy
I am doing a write up on all the mods and will provide links etc to files, will add another post shortly.
The quality I get from this modded old boy is insane . all Z-wobble gone 0.6 nozzle - this could almost be resin

I've done it. A sub 10 minutes, some additional details as well. Sub 10 minute
Accelerated 30000, 230mm sec, corners 30mm
What a great machine

Thanks Nophead, there is faster and better quality to come. Abs would be better quality. What did you think about the z tensions? It creates a tiny (0.4mm) bow effect on the z bars which keeps everything firm, I get no wobble at all. My Klipper config attached.

Thanks.
I haven't seen any z-wobble on my machines. Is there play in your linear bearings? Do your tall parts get a 0.4mm bow in them?

The bow effect is constant throughout the height so no. The standard x assembly does shift around, you can literally push from side to side, the smooth rods are not man enough to resist inertia or the lead screws. With the tensioners I am seeing perfect layers short. I can defo do a tall print to prove perfectly square.

The Mendel90 design has neoprene sleeving in the Z couplers to allow the lead screws to move angularly without putting stress on the Z rods. I see you have metal couplings which are probably stiffer.
