I have an E3V2 with a cr touch kit installed, with the appropriate firmware and use cura. When I go to ABL, both from the menu or G29 command in the pre printing code, only the center and 0,0 point are probed instead of the grid.
that paragraph was written before i attempted a print, and as you can see from the (residue? scraped area?) everything i said is still a present issue. what do I do?! this is so frusturating. do i need a new bed surface? a new nozzle? plus i have a clicking sound coming when i print... i think this was the grinding but who knows... this is kind of a nightmare

also now that i have a crtouch installed, is there any reason to keep those springs and knobs on the bottom? why shouldnt i just install something like a spacer where the springs were?

#

ill give it a pass of windex and water and post what it looks like after

You still have to level your bed. Adjust your z limit switch

My nossle looks like that after a while too.

#

i agree. have to make sure the bed is level as possible. the crtouch i belive just fixes the imperfections of the leveling

i'll level it again, but my concern is that it consistently only probes two points before printing instead of the typical 9
