Hi all,

I’ve had my Form1+ for about 2 weeks and absolutely love it!!

I previously been printing with FFF type printers and there are a range of calibration models we use to fine tune our printers & filament, the simplest being the 20mm x 20mm x 20mm calibration cube.

I mainly print mechanical parts so dimensional accuracy is important and I understand calibration adjustment is done via the X/Y Scale tool.

Is there a “go to” calibration part that you SLA guys use to calibrate your printers?

I have some ideas, but don’t want to reinvent the wheel.

Many thanks,

Steve

I made this for that purpose. Be sure to imagine it as one huge block.

> You can get better prints by knowing about the errors in your Form1+. You can even print this at the same time as other models so you don’t have to do a special run. And if you post your results, we can discover what is typical is too. I made this test file for the community and just printed it: [https://www.dropbox.com/s/qbbuyuo4oxdqepv/Form1%2B%20Scale%20Test.form?dl=1](https://www.dropbox.com/s/qbbuyuo4oxdqepv/Form1%2B%20Scale%20Test.form?dl=1) (Form1+ Scale Test.form) And then measured it with a digital caliper. And from the various measurements I was able to dis…

Perfect Josh, thanks!

I was thinking something very similar, but will use your test as I log the results with your original post.
