Hello! I've just printed this excellent design for a very old UMO. I know I need to rotate the heater block but due to the age of this printer want to make sure I don't break something. It looks like the heater wiring is threaded straight up through the head and doesn't look like it wants to bend. Those who have done this rotation, any techniques you care to share? Thanks!

Good morning! I am still testing, but so far, so good. I was able to modify one block in Fusion, filled in the limit switch holes for stiffness, then thinned the back for clearance. This meant that the retained nut and part of the machine screw head that clamp the bushing sat proud of the surface, so once I had enough clamping pressure on the busing, I ran the back of the block along a fine metal file until everything was flush again. I haven't tested this yet with the bed all the way down, I think the Z screw will come in a bit and I will probably know for sure then. I would upload this mod, but a) I don't know how and b) I'm not yet confident that my solution works full travel. I will look at your modified version as it may be better than my work around. Thanks for continuing to support this! Cheers John

Thanks for your response! I'll file down the one I have and see how much material I need to remove, will see if I can post a comparison here. Cheers John

Just installing these on a UMO without the heated bed. Having the same interference issues on rear x axis, the block hits the lead screw and vertical rods. About 0.3mm from what I can see.
