So as many of you know, davinci calibration is shit. Absolute shit. So here's how to do it manually.

After 3 hours of heating, Reheating, failed calibrations. I gave up and went online. Found a comment about how to quickly calibrate and it worked flawlessly.

1. Print a sample print ( vase, keychain etc)

2. Have your hand on power switch, once extruder begins to print purge line, kill power.

3. Working quickly and carefully, manually move the head to the back right of the bed.

4. Get a strip of paper and slide it under the extruder. Move the screws until it just bearly exerts resistance on the paper (you can feel it).

5. Repeat for left side (moving exturuder to back left) and front (moving extruder to middle front)

6. Recheck the paper (again on each corner) after you have it dialed in to confirm bed is uniform.

7. Turn on power and print another sample print. Be ready to stop it if it ends up colliding with the bed. Once you're results are met you're all set!

8. Don't ever use the calibration feature ever again.

9. Don't ever use the calibration feature ever again.

10. The calibration feature should be taken out back and shot.

Some notes: if you wanted to get super fancy, use a small newton scale attached to a piece of paper to ensure each corner has same amount of resistance when running the paper under the extruder. (This would be very time consuming and is kinda just an afterthought idea.)

Saftey: these things are hot. Like hella hot. Enough to easily melt skin. So don't touch hot extruders
