Is it my imagination, or is camera alignment much better now? These days my cuts all seem to go where the camera shows the preview, within a mm or so, which is much better than a month ago. Is anyone else seeing this?
Nope, not your imagination. Theyâve been rolling out improvements behind the scenes for a while now.
Not your imagination, mine has been spot on!!!
Mine had been within 1 mm, too. All. Day. Long.
Iâm not seeing it. If anything, my GF is noticeably farther off than when I first received it. Was within 1/8" ± initially, now pushing up againstg 1/4" pretty consistently regardless of bed placement.
I wonder if itâs a per-machine calibration. For example, when my lid is solidly closed, thereâs a bowing on the right side, which would mean that the camera is slightly tilted to the right when the lid is closed, which GF would need to figure out and correct for. Someone elseâs GF might have slightly different camera positioning, based on assembly, or where itâs positioned, or how they close the lidâŠ
Grab a level and make sure the case is level. The slightest difference, not closing the lid completely, having a slight bend in the case (those rubber feet tend to stick and the case has a slight amount of flex in it) having the crumb tray not sitting down in the dimplesâŠall of those can throw off the placement. (Not entering the correct height of the material can throw it off a LOT, so make sure to always enter the height for Unknown Materials.)
The printer is level, and on a level surface. Thereâs a slight bow in the right side of the lid, which appears to be built in - itâs there when the lid is open, too. The front is closed securely on both sides, and the back is the hinge which is fixed in place. Iâve seen others report the same âissueâ - it doesnât seem to affect printing, and itâs only a small bow - less than 1/16th inch. So I donât think itâs a problem, just a slight difference between GlowForgeâs that they might need to correct for in camera alignment.
Yeah, the lid glass on mine appears to show the same bow on the right.
My understanding is itâs actually not the lid glass, but the side panels that are set just a little low when that happens. Thatâs why I suggested a level - itâs the only way to check that the actual center section where the camera is, is level. (My right side is sunken by about 2.5 mm. Just a hair on the left.)
But youâre right, it doesnât affect processing if the center is level. My print placements tend to be right on the money.
I took two levels to mine and once leveled out via shims under the feetâŠthe lid rubbed on open and closingâŠso it âunleveledâ it back.
When my Pro first arrived it was dead on. Then it was off to the right, but not up or down. Then it was dead on again. Then same right - left issue. I never really know how precise it will be, but itâs never as bad as the 1/4" some people have to live with. This weekend it was back to being off on the x-axis again.
This sounds like material variation - remember if the material is even a tiny fraction higher or lower than âexpectedâ, the preview will be off. That means bowed material, material thatâs sitting on a small piece of debris, any material when the trayâs got debris underneat, non-PG material thatâs not the thickness entered in the UI, etc.
