b9 creator ver 1.2

Post#1 » Mon Oct 15, 2018 7:50 pm

what should the machine specific multiplier be set to on the ver 1.2? I seem to have really over exposed my pdms after only about 5 grows. Please help me out here. Just re coated a vat and calibrated the build table and projector. New resin. I'm lost

What is your setting now? How long have your prints been taking? If u get the test print done and it's good you should not have to change any of the settings unless u change the lamp or the projector.

set at 1.0. I bought this used and don't know of any mods to the projector. I put the booster kit on my ver 1.1 and had to turn down the msm. So I calibrated the build table and the projector but the prints are not sticking to the build table. Just had my 3rd failed print of the test pattern to even see if the thing will print. What am I doing wrong? I really need some help

What are u showing as lamp hrs.?

Go ahead and up the MSM to 1.2 and see what it gives u. This will increase all your settings by equal amounts of 20% (exposures, etc.).

How far off is it? It might be the projected image isn't the right size and you need to recalibrate that first.

msm at 2.0 changed nothing. Mike is there something I am missing? You say recal the projector but I used the orange template and it was sharp. Wasn't there something in the computer settings that wouldn't scale? I am running windows 10

nothing was selected under advanced scaling settings. "let windows try to fix apps so they're not blurry" is set to OFF and I left it OFF. Custom scaling size was not chosen either so I entered 100%. I turned the msm back down to 1.0. I am printing another test pattern now

that didn't do anything. What if I did a custom scaling in windows on the second monitor of like 105% or so? The middle square is now 4.8 mm

You say it's off, but you don't say by how much. You say the image is sharp (that's good!) but you don't say if it was exactly the correct size.
It's hard to what to suggest without knowing the error amount.

Thanks for the help. After calibrating the build table I then calibrated the projector like it says to in the instructional video. I raised it to the highest peg setting and fine tuned it so that the 30 micro orange template lines all illuminated nicely to fit. I adjusted the top black ring on the projector all the way to it's stop at 30 and the lines were sharp and focused. In all the test pattern grows I used balance and fade to even up the corner squares and I got them really close. The middle square was at about 4.8 mm. I turned up the msm little by little but even at 2.0 my center square would not get to 5 mm. I tried things as described in my previous comments on this thread. I think it must be something between this window 10 laptop and the grower. The last thing I tried was to adjust the X and Y axis calibration multiplier in the printer specific settings. I set them both to 1.10 and the resulting test pattern grow was much smaller. I since set them both to .95 and the test pattern is just right. The question is. Is this an acceptable thing to do? Will my grows produce the correct size? I am about to find out.

By setting them both to 0.95, you are basically saying that your grid calibration was about 5% too small. That's not much and it's hard to see even using the plastic grid pattern.

Normally one might be set to 1.0 and another axis .95, for example, really meant to correct any errors in the projected aspect ratio.

But what you did should result in correctly sized grows.
