Hi,

how do I tell how many hours the projector bulb has on the clock? Vivitek projector.

I'm having a few issues at the mo with prints looking they may be suffering from under-exposure so want to check the bulb hours to see if exposure needs increasing or a new bulb required. (or if this is the problem at all)

It does tend to be on one area of the build plate (large area) SolusProto some 'soft' looking areas on the print from a particular part of the build plate and some areas that look like a slice has shifted from the main print a little. As I clean the prints it looks like some areas on these parts hasn't cured. When I clean with IPA these areas become soft.

I've calibrated build area and build plate, recently had new Z screw fitted. Just trying to sort this area of the plate - I'd avoid that area altogether but not possible on most builds.

I've double checked the supports (all fine) and I'm currently re-printed the failed parts on another part of the build plate to see if they come out OK there. I don't know if a symptom of under-exposure is limited to certain areas or no?

As of now, the only way to check the bulb hours is to point the projector at a wall about 4 feet away, remove the close up lens, and go into the projector Menu. It's under Status.

Also would help to post a few photos of the prints, so we can better see what's happening.
