I got a bug in my drawers to upgrade my printers to full linear… I print so much I keep wearing out the bearing wheels and have to replace them more regularly than I care for.
I’ve been working on and testing this design, and am very happy with is so far. I’m cranking out prints at 150mm/s with the stock hotend. I have a new heat brake and block to install that should get me up to 250mm/s.
I’ll be redesigning the parts once more before I release, but this should be a full retrofit that reuses most of the original parts, and preserves the original part offsets so you don’t lose any build area space. The final design will be a lot cleaner and more refined than blocky test parts. I’ll be designing and releasing my own hotend cooling system as well that will incorporate a second 5015 blower for parts cooling.
More to follow!
Curious what symptoms you have when the wheels start wearing out? I’ve got quite a few hours on my printer and haven’t touched the wheels after replacing them when it was new because of shipping damage. Never even considered that they could wear out (apart from the bearings).
