Of the two rods through the printhead the shorter one (289mm) does not fit into the bearing. It can be inserted with a certain force, but does not ‘move smoothly’ as stated in the manual. It works perfectly if I use the longer rod (298 mm). So it seems to be related to the rod not the bearing. Any idea how to proceed?
Thanks,
Check the diameter of the rod with an electronic caliper.
If you see some variation you can open a ticket and ask for a replacement.
Thanks. I measured and the rod is 8.00mm compared to the 298mm rod that is 7.99mm and the lower bearing seems to be a little smaller than the upper one. So I went to our workshop and polished 0.01mm of the rod on our lathe. Now everything works perfectly. Couldn’t wait for the rod to be replaced ;-).
