Quick update. I’ve changed the extruder mount design over the weekend and redesigned a bearing holder. All my existing parts are fairly old, having come from previous robots. I also print a lot right now. I use a spool every month at the current pace. This has created a stress test scenario.
I’ve been looking at how parts are wearing from the stress, and making modifications based on this. These two parts are causing mechanical stresses I don’t like — so they’re being redesigned. I hope to manufacture the new parts over the week.
