Fine Tuning Your Printer

Fine Tuning can be accessed via the PreForm Help dropdown menu when your Form 1+ is connected. The Fine Tuning panel allows you to make adjustments to how your Form 1+ interprets PreForm’s instructions. These are advanced troubleshooting features, for use when you've noticed consistent but small-scale errors in your models' dimensions.

Platform Height

This 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. 

Adjusting the height of the build platform

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, to give 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 your Form 1+’s resin tank and mirrors — 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

XY scale adjustment in PreForm

This tool adjusts the scaling factor in the printer’s X and Y axes. When you make an adjustment here, your PreForm scene will not visibly change, but your Form 1+ will stretch or compress the laser’s path in the X and Y directions by the amount you specify. The default value is 0.00%. You can change it in increments of 0.10% up to 4% stretching or compression in either direction — so your model will end up at maximum 104% of its designed width and depth, or minimum 96% 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.

Form Tip

The Y-axis of the Form 1 and Form 1+ is the direction from “left to right”, or hinge-to-peel, across the build platform. The X-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 any one direction, or never adhering, reset everything to default values and send us a support ticket!
