Why is the Vat not peeling?

So the laser does a layer and the Vat should then peel down at a slight angle then go back to level for another laser layer.
That’s not happening! I just replaced the laser after a year, now what?

Can you see if the laser is firing at all? It could be a SD card or SD Reader problem. That is a known issue to happen and might not have anything to do with the health of the laser.

Hmmm…didnt think of that. Thanks!
Yes the laser is firing. I’m getting cured resin in the Vat and a little bit of platform and supports on the build plate.

Could it be anything else?

does the vat tilts during boot up? if not, check the PM motor
if it does tilt, try the pre-sliced gcodes to see if it printed out ok
