Core 1 - MMU3 - Layer shifting- Help Please

I've had my C1 less than a year and added the MMU3 a few months ago, I have done fairly simple prints to start with but have been increasing the complexity and using more colours and different materials. So far everything has gone pretty well, a few hiccups along the way usually from something I didnt know.

This week I attempted my longest and most colourful print with disastrous results, a major layer shift after completing over 50% of the print.

I was attempting to print this.  lightning-mcqueen-kit-card-disney-pixar-cars-movie

I am running the latest firmware on both the C1 (6.5.3) and MMU3 (3.04)

I was using Tecor PLA+ from Inkstation. 

I used the "Generic PLA" profile in PrusaSlicer (2.9.4)

Could someone tell me what happened and how do I fix it?

thank you

Kind regards

Jan

RE:

blobs on the wipe towerfrom dripping filament? Search for the topic. If so, a tool change GCODE

G1 Z{layer_z+10} X10 Y10 F3000

or the like may improve things. But check the wipe tower at the failing height.

 

We'll just put some bleachers out in the sun-And have it on Highway 61

Hi mnentwig

Thanks for replying, there are some raised areas on the wipe tower but not on the print itself. it seems to have done it on several layers.
