I like the idea of using a slider to adjust the height of the build platform. Having the adjustment horizontal is confusing. I suggest that this control is vertical, as it correlates to what is happening with the build platform, maybe even use some basic imagery to illustrate what the fine tuning will do. The X-Y adjustment should also correlate to the users perspective somehow. Maybe, on a separate dialog box Y adjustment is vertical, and X adjustment is horizontal, as if the user was looking down onto the resin tray from the front of the Form1?
Oooo good idea…thanks for the suggestion!
