All round print issues

[noiseboy72]

Shift is normally caused by a problem with the drive. This can be a failing cable or stepper motor, problem with the set up of the drive electronics or a sticky mechanism, causing the drive to stall momentarily. Check all connections are good and use a meter to do a continuity check on the cables.

215 - 220 is not an uncommon print temp for ABS, but is a bit warm for PLA. The clicking is usually a sign of a clogged extruder. Strip it down and clean any crud out. TBH, the worst part of these machines is usually the extruder and they often benefit from some upgrading. A sprung tensioner is a good starting point and is usually a cheap and easy upgrade. If you are printing with too high a temp, the material will soften too far up the extruder and that can cause jams and print issues. The PTFE liner can also become misshapen, leading to further jams.

The spaghetti at the top of the print may suggest that the leadscrew calibration is out, so the gap is increasing as the print height increases. The first thing I would check however is the bed height is correct at the start of the print, as it maybe a little high at the moment.

I don't really consider the CTCs to be a good starter printer, as they do need tweaking to get the best out of them. Persevere and you will get there!
