Comment on linear rail upgrades, looking for feed back.

  If you’re concerned about durability, you could potentially add in some bolts to use as a slip-in rigid spine to further reinforce the design. I’m thinking something similar to how concrete is tensioned to provide rigidity and strength.

  I’m spitballing ideas to see if I can spark something workable for you.

  Check the mk3s printable parts , every motor on the mk3 is mounted using printed brackets, abs/Asa holds up really well and honestly petg does as well, I had a petg failure on my x axis after doing days of enclosed abs printing which says a lot considering it was easily 50+ deg c in the enclosure. I’ve since put probably a few thousand hours since rebuilding with abs and have had no issues with the printed parts.

  Vorons also use printed motor mounts and they also hold up with high enclosure temps for extended periods

  RatRig V-minion uses printed (ASA/PETG) parts for all motors, and 10k mm/s² acceleration is normal. Granted, a smaller bed slinger, but still.

  Vorons use 3d printed mounts for all of their motors for another reference (5 perimeters and 40% infill iirc). I think it would be fine given you’re using asa/abs and maybe thicken the bracket model up a bit where the motor mounts if you want.

    Thanks for the reassurance, lol. Taking a look at their mounts for… blatant plagiarism inspiration
