I’ve been in the process of replacing my z-axis with the CBeam Linear Actuator Bundle set from OpenBuilds. Its pretty much all set to install except that I don’t particularly like the height at which the Maslow z-motor wold be sitting (atop the 250mm tower). I can go that route no problem but if I could somehow come up with a plan to set the z-motor lower down then I think I’d have a winner. I know that currint the rail at about 150mm and re-drilling and re-tapping is an option and I may end up going that route. But for now, I’m looking at options.
On the OpenBuilds website I came across their Reduction/Stand Off Plate Set which would essentially convert it to a pulley system. It appears to have been built as an upgrade to their Mini Mll as a z-axis upgrade.
My thoughts are to mount it on the bottom of the CBeam rail, between the sled and the CBeam, using spacers for clearance. The Maslow z-motor would be oriented just as it is now, spindle down, and I would enclose that underspace in acrylic to keep dust & debris out of the belts. Just curious as to any thoughts on this.
