Guys, I have a really hard time with delta 8800.
It was great after the assembly. Machine was printing right away.
But something happened and printer started to scratch printing surface. It didn’t want to calibrate itself, engines made a sound like fart ( ), I checked the piezos, was fine. I made multiple test. I even disassembled the machine and put together once more.
Sometimes engines seems like clogging /jamming. I checked the lubrication and belts (condition and how strong it is stretched). It seems fine. Moved by hand goes smoothly.
When I start print after the calibration (and store settings) it bums the the printing bed during heating filament and when it starts to print looses calibration completely. It looks like right after the calibration printer subtracts like 5 mm.
You can see my struggle under the following link:
There are a couple films and pictures describing,what i’m dealing with. At the end I attached pictures to show, where is XYZ after fault print and where it is after the calibration. If it is not obvious I explain, the printhead hits surface and tries to go about 5 mm below the surface.
I read all the forum and I didn’t found solution to the problem.
