Hey guys, I have built and have managed to get my kossel mini printing... except for one small issue.

My print is starting too low.. I have done the following..

1. G28, home printer
2. G1 Z10
3. go down in 0.1 increments until paper just fits between nozzle and plate
4. send M114 for XZY
5. Get default Z position and minus the Z coordinate.

So in my case, my Z height was 239 to start for the kossel mini.
Pronterface told me when I did my calibration I was 2.4mm off the plate, so 239 - 2.4 becomes my new z default.

6. I make sure my Offset for my probe is correct, I check again and again.. I also have my Zprobe retract calibrated OK to push it back up after it's spot check.

My print starts fine, but always 3 or 4 layers too deep. It blocks the nozzle its so close to the glass. On the 3rd layer or so, it starts extruding as it has enough space now.

I adjust my Z height again... and again.. and again.. and do it over and over, and no matter what value I use, either for the XYZ or the offset, this thing still prints 3 layers too low...

Im sorta tearing my hair out here, I can't think if what I missed as Ive gone over it so many times
