Hi, I would like to ask anyone for help with figuring out the ams lite part in the A1 g-code,
I’m working on a TPU 95A profile, it works, but has one problem, the AMS lite doesn’t push the filament far enough and I would like to try to change that, so that the AMS lite would be able to print with TPU
Here is the G-code for a filament change:
