Print Better by Discovering your Form1+ Advanced Calibrations

Heres what I got. Measuring from the bottom, the values were not bad (100.02 mm in the Y & 100.09 mm in the X), but could use a tweak. What concerned me more was the shift. All cubes are shifted away from the hinge and away from the front until 4mm away from the base where you can see the line, then they’re perfect. I know it’s kind of stretched from the peel process, but any other explanations? They’re also ~9.25 mm in the Z, just for info. I do know about the Z compression on the first couple layers.

Well that line 4mm up is probably where the double-cure ends. They have had issues with base layers coming apart so that’s the reason for the double-cure being taller than it used to be. The skewing would normally be a loose platform moving, but your tops are so perfect I doubt your platform is loose. My guess would be it has something to do with resistance changes on the circuit board as the board comes up to operating temperature. Maybe see what @Formlabs support gives for a reason.

Thank you, I will definitely be contacting them to see what’s up.

Edit: This was a great test and gave me good insight on how my printer is performing. Also, the additional test cube I added had spot on dimensions, except for the bottom ha.

Good to hear. Let us know what their explanation is.

Josh - Sorry I’m rather late this this party, but any chance I could get the file, I tried dropbox, but it was not available…


I bet @ChristopherBarr has a copy. Dropbox only gives me 2gb so I occasionally delete files I don’t use anymore, and I don’t always remember which ones have been shared long ago. I can’t find a local copy either.

There’s also these test objects and calculator I created later
