Hi,
I recently bought a second hand UM3 through this site and everything seemed ok but i am starting to have some problems. I realise now the print head is not level and I cant find anything anywhere about this as a problem. (see photos)
This first came about when i noticed the sliding blocks were not level, so levelled them, this made the slant of the printhead much worse and the printing deteriorated further. I have tried slanting the sliding blocks in various ways but no amount of doing that seems to stop the print head from leaning to the left. I realigned the axles, checked the axel isnt bent, messed around with other bits but cant seem, to fix the issue and have found nothing online even noting it as an issue.
(AS can be seen in the photos, the material will not stick to the build plate when moving along the x-axis near the middle of the plate, i suspect the offset caused by the front build plate screws causes it to almost be level despite the print head, near the front of the plate).
All calibration print photos are with the left sliding block tilted, it fails right from the start if the slideblock is straight)
Any help would be appreciated.
