I want to re-calibrate my projector focus; I'm just not sure the easiest way to go about it.
I've seen several posts about calibration and know how to change the focus using the screw in the back of the printer but I was wondering if there is a written 'factory calibration' procedure that can be shared now that Autodesk isn't producing the hardware anymore.
There must be some trick or tooling used since the best I can come up with is to lay a piece of paper on the tray with the 'showcal' image projecting.
How can I be sure the image is actually the correct size?
How do you tell if everything is in the correct focus - and not just slightly blurry which would have a big impact on fine resolution?
Do you use microscopes, eye loupes, calibrated glass scales, image capture....?
