"Small Feature Speed" does not obey "Minimum Speed" #29

Closed kulfuerst closed 4 years ago

kulfuerst commented 4 years ago

Application Version 20191003

Platform Win10

Printer Anycubic i3 Mega

Steps to Reproduce Set "Small Feature Speed" to 50%, set "Minimum Speed" to certain value (e.g. 15 mm/s)

Actual Results On layers that do not take long to print and that contain small features, the minimum speed will be halved leading to extremely slow feedrates and quality issues.

Expected results The speed does not drop below the value chosen for "Minimum Speed"

Yes, you're quite right. I discovered this myself the other day when I was printing a very small part and wanted slow layers so it didn't overheat. I found it was actually printing at 2.5mm/S. Part came out really nice! Anyway, I'll take a look at not reducing the speed below the min speed.

I've fixed that for my next release and also submitted a PR to UM. Thanks for the feedback.

I believe that, if anyone, you're the one who deserves all the "thanks" :)
