Did all the calibrations/checks and such and sent my first 2 color print.

Everything worked and the test print came out great.

While building the mmu tho, I seen there was a updated set of extruder housing parts, so I printed those and did that upgrade as well.

I am now running into a issue where the mmu will not load the filament all the way to the extruder. The filament stops feeding right as it gets to the end of the front tube on the extruder side.

Basically it's no longer feeding far enough to hit the extruder. The front tube is still the same tube and nothing changed length wise.

I even found the tube length setting in the LCD menu and tried messing with that, but nothing changed.

How did the feed length change suddenly and how do I go about getting working/feeding all the way through again?

Also ideally I would actually like to make the front tube a bi longer, so I guess I would need to change it further to account for the extra length of the new tube.

Is tilting the object the only option for limiting the curling I'm seeing? It starts at about 2h 43m into the print job. The first two attempts were made using an off brand PLA (grey). I am now printing with Panchroma (Polymaker) black and it's doing better but still curling at the corners as shown below:

Here is the 3mf project file as well.

The overhang tests that I've used al come out fairly well but I don't think they really test for the curling issue I'm seeing. I've tried lowering nozzle temps, leaving the top off, putting the print fan at 100% and so far I've minimized the curling but it's still there. 

I think it would be a great feature to be able to flip a model from left to right from the printer settings.  It would be an easy way to create a variation of a model without having to re-slice, and should be easy to implement by just negating the x-axis position and velocity values.  The purge line would end up on the left side, but that's moved in the past (from the MK4, IIRC), and I can't think of any other consequence.

The following features are supported:

• Filaments from Filament-DB automatically show up in PrusaSlicer as User Presets
• Calibrated parameters are selected based on the current nozzle
• OpenPrintTag compatible tags can be read with a suitable reader and will select the filament automatically in PrusaSlicer
• If the spool is weighed and that weight is recorded with the spool, the remaining filament is calculated. When an object is sliced, PrusaSlicer will warn if there is not enough filament available on the spool.
