aye, I have never seen an instance where the checksum was able to detect a failed flash in a way that could not be determined another way, such as looking at the LCD screen on powerup.

@caguilar Agreed. These are so similar to the standard tool heads that I dont think there is much to be gained by having MER build them.

I was just looking over some support data and 7 issues with mini 2 we have been contacted about was due to difficulty removing filament, in a very similar way to what we were seeing with these machines back in December.

kent updated subscribers of T2998: "shiny" printed parts are still being found in production.

I just talked with @david.hall and we decided that for parts that there are two of, such as z-lowers, z-uppers, and x-ends, we need to make sure they are consistent across a single machine. For parts that there is only one of, we can be more lenient on parts that are more specular and less diffuse.

Here is the line for the filament timeout, in case we want to make an adjustment there. It's at 45 seconds now. I think even something long like 5 minutes would be ok. https://code.alephobjects.com/diffusion/MARLIN/browse/devel/Marlin/Configuration_adv.h$934

kent added a comment to T2875: Usability enhancement: Request to extend time to load filament from GLCD.

This seems to address the issue where you need to click "extrude more" a few times before any filament comes out which is nice. It looks like you have about 30 seconds to load more filament before it starts dropping temp, so that's still the same. Maybe there is a way that we can raise that up to a minute or two.
