Hi!
For some reason my Anet A8 has started printing 1cm too high. It happened after one print finished, when I tried to start the next one. I have adjusted the heatbed, lowered the nozzle, disabled the steppers and hand-moved the nozzle down to the bed. It is always 1cm:ish over the bed when is start a new print, no matter which print I do.
I am using Skynet firmware. No auto-level heatbed.
Cheers

Hmm, cant find anything similar to that. Made in Cura. Anything I can search for in the document?

Nah, this print worked before ^^
Slicer is at 0.06mm layer height
Check PM :)
(Not my model, so sent file-link there)
Found a temporary fix (could be permanent, it works well). Removing these lines, then hand-setting the nozzle to the right height before each print:
G28 Z0 ;move Z to min endstops
G1 Z15.0 F{travel_speed} ;move the platform down 15mm
There is no sensor that could be broken, I assume? I dont have auto-level, or anything like that. Just a stock anet a8.
