Align Bed

I lost my base settings for my 3D printer. I needed a quick way to find the correct origin offset for my print bed. I created a SCAD app, to create different sized measuring blocks to align my printer.

Steps to align.
1) Print a set of blocks
2) Measure from one block to nearst edge.
3) Measure from the opposite block to nearest edge.
4) subtract the two measurements and divide by 2. That number is the amount of change needed to correct the origin for your printer software.
5) Print blocks again, and recheck. Repeat if still a little off.
Now do the other direction.

Warning, you may have to do multiple passes. For me, my software and print bed are 90 degrees out of alignment. My origin is actually at the left rear of printer, but left front for the software. So when I was adjusting, I keep mixing up weather I was adjusting left-right alignment or front-back alignment.

I have also included my parts list, that includes the model of micrometer that I used. B
