Tolerance calibration makes small adjustments to the exposure time of each layer of printing to fine-tune results. This may be necessary depending on your print environment, resin age, or other factors. If you are unsure whether you need to calibrate, reach out to our support team.
Tolerance calibration will print two small blocks that slide into each other. This tests the printer for fitment, and ensure that your printed parts will sit correctly. To begin, open SprintRay Software and connect to your printer. Then go to the topline menu Printer>Calibrate Printer. On this screen, select the printer, resin, and layer height you need to calibrate.
Next, select 'Tolerance Calibration' (should always be performed before dimensional accuracy)
Your printer will print two rectangular blocks. Once finished, remove the blocks from your build platform. Clean and post-cure the blocks exactly as you would any other part printed with this resin.
Once your parts are cleaned and cured, gently slide them together. Record the number that the window reaches without forcing them together.
After the part is done printing RayWare will prompt you to input the score your test revealed. If you were disconnected during this process you can get to this screen by going back through the calibration menu and hitting "Skip" instead of "Print" on the last step.
Repeat this process until the slider rests on the 3.
If you've made a total of three adjustments without improved results, reach out to our support team and stop printing calibration tests.
