I have a Taz 4 where i have upgraded the extruder and flashed the taz 5 firmware. I never had any problem in the past with printing until recently where every part i print over a few cm in height have some layer offset issues.
I tried printing the exact same file multiple times however it seems that the offset issue happens at a different height each time. Just to rule out gcode issues i tried to reslice the file with a different program with the same issue. Ive used both Cura and S3D, and when using a gcode viewer i do not see any kind of issues.
I have also tried tightening both the X and Y axis timing belts to make sure there is enough tension in the belts. I have checked the set screws on the stepper motor clamps and both are secure and extremely tight. I’ve also check the bearings, bolts, screws, nothing seems to be loose.
I have tried to orient the parts so that while printing it would minimize movement in one of the axis’s to make sure that slipping is not the issue. I did this for both X and Y and there were no changes, there was still an offset happening at random heights. I have also tried to relevel the bed to make sure that it was not somehow contributing to the issue.
Not sure where to go from here in order to pinpoint if this is a mechanical or software issue.
