XY Offset Calibration for Chitubox
Description
The actual MSLA resin printer XY build area will often not match the screen display area because the screens are assembled in such a way that some of the edge is blocked to stop light bleeding. The screen area must be calibrated in Chitubox if you really need the screen sized to the last microns. In Chitubox there is a checkbox in the Machine tab of settings called Build Area Offset. When you check that box, it allows you to enter the difference from the actual area. See https://www.chitubox.com/en/article/support/indepth/technology/33 I calibrated my screen by printing thin 10mm square boxes at each edge of the screen. I made the model in Windows 10 3D Builder and embossed them with the letters used in the Chitubox Build Area Offset settings so I could tell which is which. I measured each box with calipers and subtracted the dimension from 10mm to get the difference to type into the slicer settings. Chitubox lets you enter the number to the nearest micron. Unfortunately, I haven’t found a way to get around typing it into the settings for each resin profile I use. I have only made a model for the 5.5-inch screen on my original Elegoo Mars so far but it was fairly easy to make. 3D Builder is free in Windows 10. Sample measurements: A 10 – 9.04 = 0.96mm B 10 – 8.73 = 1.27mm C 10 – 8.19 = 1.81mm D 10 – 8.45 = 1.55mm
