print speed of machine keeps changing

here is something weird i'm noticing i have my speed set to 100% but sometimes when i turn the machine on the speed sets itself to something other then 100%.

I only noticed this because i had a 20 minute test that seemed to run way too long and i thought the MMU errored out.. i go check the machine and it is running but the time remaining was still saying like 15 minutes. i thought that was odd and i noticed the speed setting was suddenly set to 60% not 100%. this happened on another print after i reset the machine where the speed changed from 100% to 80%

not sure if this is a documented bug or not?

this is a pretty nasty bug because not only does it throw off the print time of the machine but by slowing down actions it can cause material problems like over extrusion or overheating. you are setting everything based on 100% speed.

i don't know how to use github but if somebody knows how to report this bug to the higher ups please do it.

I think it would help if you could provide a gcode. Ideally it should be reproducible.
Haven't seen it on my MK3+MMU2 yet.

I think I just see it on the soluble setting prints. both interface and full.
