karrad assigned T10216: Bio & Marlin .166 Home buttons misplaced to Greggb.

As homing is done right at the beginning, and is not required past this point (we specifically recommend manually moving the head and bed) we removed the icons. We have updated this to make it more clear that one is for the syringe and one is for general movement:

@marcio On my first test here I got a clog with PA-CF. Would it be possible to increase the rate of retraction after purging? It seems very slow at the moment compared to the successful Mini 2 and Workhorse change filament options. (Tested on 2.0.0.171)

@Dante This is what we need clarification on. While using the Change Filament Option on workhorse we cannot duplicate this issue. Here is a photo of one I just pulled out of my workhorse:

Mon, Oct 7, 3:09 PM · Redgum
karrad added a comment to T10278: Update Pro change Filmaent option to include purge.

With our requirement to print both flexible and standard materials out of the same tool head, the feed path was constricted on the Aerostruders to allow this. This is what is causing the additional jamming, and unfortunately cannot be removed while still being able to print flexible and solid materials.

karrad added a comment to T10257: Filament spools internal to machine.

@Greggb As proposed above, we can have the spool reels be reversible. We can ship the unit with them installed on the interior, but have the ability for them to be swapped to the outside. Not only would this allow for larger reel sizes, but would allow customers to do hot swaps without fear of ruining their print.

Tue, Oct 1, 3:46 PM · Akita
karrad added a comment to T10257: Filament spools internal to machine.

I feel having them mounted externally on the sides for access a filament switching would be the best user interaction. We need to maintain the locking cabinet when heated in order to maintain a UL cert, and don't feel we can budge on that. Any time we have filament run out or need to be swapped, it will increase the likelyhood of failures.
