How does layer change work? What are the mechanics of it? This page will answer those questions.
At each layer change, these actions happen:
1. laser stop
2. PM motor starts to tilt the vat downward, based on PM Reset distance (the length of peel) at PM Moto speed
3. at the same time of “2”, if Z Follow is not zero, the build plate will move down at the distance of Z Follow and at the speed of Z Moto Speed.
4. PM Motor reaches to the specified PM Reset distance and start to move back
5. As step “3” is completing, the build plate goes back to the current layer position. Then it moves up to the next layer (depends on layer height).
