I'm sitting here waiting for the post office to send me a notification that my my 10mm linear rod bearings would finally be at the post office. I'm the meanwhile i had replaced the x and z rods bearings with plastic abs bearing analogs that i found on thingiverse.
They did an ok job and i managed to print a benchy that didn't look half bad and some other stuff. I noticed half-way in my enthusiasm that my z rods kept popping out of their sockets at the bottom and that my whole... x/z (?) configuration had a decent amount of inwards tension. I haven't managed to keep the rods in the sockets since then and now im just re-adjusting the motors and couplers and all that to try and have everything sit in its place a bit more comfortably. I noticed theres probably around 15mm of extra space in the top hat of the z axises for the linear rod and i was planning on filling that with sugru and letting it sit for a while and then forcing the top back on. (Let it sit for a while to become less adheasible but still malleable).
Anyone else having these issues and how did you work them out? I also have a roll of copper tape i was thinking of using since thats stiff but still comforms to give a bit to create a snug fit.
I realise the plastic bearings probably create too much upwards lift with their friction even with the copious amount of RC CAR bearing lubricant i had sitting around.
