Fine Tuning is an advanced troubleshooting feature, for use only when there have been consistent, small-scale errors in your models' adherence or dimensions. Fine Tuning can be accessed through the settings menu on the Form 2 touchscreen.

Platform Height

The Z Fine Tuning setting changes the “zero height” between the build platform and the bottom of the resin tank. It can be adjusted to place the build platform either higher above the resin tank’s PDMS layer (“higher”), or closer to the PDMS layer (“lower”), by up to 1.0 mm, in increments of 0.1 mm at a time. 

When to Go Higher

If you consistently get prints with very thin bases — and you’ve already tried increasing base height via the Advanced Support Settings — you’ll want to move the build platform away from the resin tank bottom. Raising the build platform gives the base more room to build. Move in increments of 0.1mm, and try small prints until you get printed models with consistent support rafts.

When to Go Lower

If your models never stick to the build platform — despite double-checking the cleanliness of the Form 2’s resin tank and glass optical window — try moving the build platform closer to the resin tank’s bottom. Sometimes a little nudge is enough to make your models adhere and build correctly.

X/Y Scale

The X/Y Fine Tuning option adjusts the scaling factor in the printer’s X and Y axes. When you make an adjustment here, the Form 2 will stretch or compress the laser’s path in the X and Y directions by the amount specified. The default value is 100.0%. You can change it in increments of 0.10% up to 5% stretching or compression in either direction — so the printed model will end up at maximum 105% of its designed width and depth or minimum 95% of its designed width and depth.

This is an advanced tool, for when you’ve noticed and measured a consistent discrepancy between your model’s design and your printed results.


On the Form 2, the X-axis is the direction from left to right across the build platform. The Y-axis is the front-to-back direction.

When to Contact Us

If your models are consistently the wrong dimensions, skewed by more than 5% in the X or Y direction, never adhere, or are severely displaced on the build platform, reset everything to default values and send us a support ticket!
