RE: Failed Y-calibration of a new CoreOne
Mines really stabilised after the advice here - really appreciated.
I’m about 100-200 hrs of printing after the new firmware (strobing tightening method) and gantry bend; so far without it complaining at all about being out of alignment. (Multiple power cycles etc)
Generally it’ll now do a couple of homing movements at corner, then just do its thing.
One thing to note is I had to do a factory reset after the new firmware install to get it to stabilise with calibration using strobing method for tightening.
RE: Failed Y-calibration of a new CoreOne
I finished my assemble, except when doing the Y calibration test; it failed. I was informed to tighten the belt; I did just that to the point whereas the belt tore from the nextruder holder. I was surprised cause I tightened the screws well. How am I suppose to tighten, knowing there is a strong possibility that the belt tears off again ?
@Butters how did you tighten the screws? Are you turning the left and right screws by the same amount? If not you WILL bend the gantry to the point that Y calibration fails. I suspect that if you just blindly tighten you will get a severely bent gantry and I can imagine a scenario where the belt might get pulled out of the harness.
Also to @Jürgen's point, you have tendency to do "drive by" postings whereas we give advice and you never respond only to post again a month later on the same topic. So I'm assuming that you... finally... resolved your issue with the profiles?
