very nice, Where did you get your glass? I'm using the 2ml 3$ a sheet glass from lowes, and i have a LOT more clips on mine than you do mainly to hold the heater to the glass more securely so that it will heat up more evenly

I got the glass here

I ended up cutting the corners with a dremel with diamond saw blade, worked great
its very stiff/flat, takes some time for the heat to sink in.

I noticed that since the probe is offset from the hotend it can only probe a portion of the glass

i got the 1/4"

Yeah I have mine set to 0 and 250 i believe, as close to the clips as i can get, I also have my endstops adjusted so that 0,0 is just inside the clips.

Stupid question: So now, i adjust the gap between the glass and the head
I assume in the slicer, and only in the slicer?

so if i set first layer heigth to .2mm it should be .2mm??

Thank you so much for all your help, I really do appreciate it

FYI - Mini binder clips take up less of the glass and also don't stick up as high as the common small binder clips.

I didn't look at the code close enough, the decimal points only needed to be removed from the X and Y offset points, you still need full accuracy on the Z offset, so add the decimal point back to the Z offset. Also to make adjustments, as a general rule, the more negative you make the number the closer to the bed you are getting, the more positive it is the further away you are. I have been getting my offset lately and then making it roughly .15 more negative jsut to get it closer to the bed. That's jsut me though.

I noticed that when its doing the autolevelling

it seems to do the middle twice and doesnt do the back right at all.

tried another print..
hmmmm weird.. not great

.2mm layer
auto width
80% first layer height
110% first layer width
