Geeetech

Ok not sure why the original thread is locked, however i've just bought an A20m after owning an A10.

First thing i did after building it was adding the bltouch sensor from Banggood.

I followed the procedure here https://www.youtube.com/watch?v=8RkT924v6kc

Somewhat confusing but i did what it said but i couldn't adjust the head lower than +0.0 despite the paper was still very loose under the nozzle.

Inserted the supplied SD card and it started by doing the point checks. Then went across the bed too low and cut a groove in the plater then started building completely wrong. Utter mess. Not happy at all. Can someone supply a working procedure,i saw 33 pages of people moaning about this. The attached docs on page1 of the original thread refer to very old versions with 3d printed brackets and before support built in so that''s really not helpful.

Please Geeetech or someone can you help. Pic attached of first run and the damage caused. As you can see i aborted the printing as its obviously wrong and printing uneven and properly messed up.

Obviously fedup still no reply, im really surprised considering these printers have alot of sales such little support on forums.

I tried to manually level the bed earlier and still had absolutely awful print look at the fat line it draws across the front of the bed i would have thought this would be even and thinner. It continues to dribble alot of resin before starting to print, this same reel of geeetech filament was fine on my old A10.
When it continues to print base in the middle you can see the nozzle riding over bumps in the print which is like it's not lifting enough to print also the small area is printing uneven already?



I am trying another youtube video today which is this.

This is for setting up A10 but i figured the same technique and it seems much more accurate way of setting up.
