Prints have multiple issues at a certain Z lower Z range
I have a pre-built MK4 and I've been using it since May without any issues. I updated to 5.0 firmware and still had no issues at all and highly enjoyed the shorter print times. I recently started noticing more and more offsets, wavy lines, failed prints, globs, etc. Almost all of the issues are within the same level of Z and if a print doesn't fail there the rest of the print looks perfect. I've recalibrated, factory reset, cleaned and oiled all rails but I'm out of ideas.
Has anyone else experienced this with the MK4 or do you have any suggestions on what I should try?
Few pictures of recent prints:
RE: Prints have multiple issues at a certain Z lower Z range
I also wanted to add that I've had 2x MK3.X printers for at least 5 years now. I've had no issues fixing various issues with those but I'm completely stumped on what would be causing this and what to do going forward. Any help is much appreciated and I hope I can return the favor.
