Hi all,
Let me say I am really disappointed with the mill at this time.
I am hopeing that it is me and not the product, hence this question.

I print in
PLA, PLA+, PETG, TPU, SOME others as well but lets start with the basics I use

• SUNLU, ESUN, Prusa, Flashforge and Teco Fillaments

I am finding PETG a real pain in the behind, Will not stick to belt 2/5 times
would like to know
Basic speed
Nozzle Temp
Bed Temps

Have STL file that I print on my Prusa Mk3's great but on the mill absolute garbage.
I am however still learning CURA For mill (SUpplied) for this and finding it clunky and not freindly at all.
also it does not always bring settings from slicer to printer?, very confuddled.

Can anybody share there results
Test print seems fine mostly a little line on lead edge but ok.

Any help appricated

My printer is the same.

Apparently you format (Fat32) an SD card and add Bin file to SD card.
then insert card and turn printer on. I am on Mar 21 as well
I assume (THATS ASSUME) as I have not attempted it yet that we will need 21 MAY, and Both of 15 JULY.
question are they dependant on the last, as I can not find anything I will assume yes and install, all, in order, one by one,
Will let you know on that. Hope to do tonight.

Question 2 (partly)

I can get it to talk to Pronterface (mostly) but a bit like a dog on a smooth polished floor, go Straight no problem, do not ask it to stop or turn. it will crash.
Have attempted to update firmware via USB as in Printmanagement ...... Crash
If I attempt anything but the barest comms it crashes.
as far as Octprint would love to be able to manage my 2 prusas and the Printmill togetherm have not tried that yet.

Question 1
Watching to see if an answer is given by someone, I am in the same boat

Hope this helps
