Mars2 Pro Vat Spacer Esp32Cam automatic power switch
Description
This is a work in progress... This is among other things a VAT stopper for Elegoo Mars 2 Pro (maybe fits some other models as well, cannot approve it) The goal of the project is to automatically switch off the printer after the print is finished. A Photo will be taken using the ESP32Cam of the finished print, sent by telegram and then the printer is switched off. In the vat stopper there is a limit switch. on top of the arm there is another part with an limit switch. I used this for my design: https://www.banggood.com/10pcs-Roller-Lever-Arm-PCB-Terminals-Micro-Limit-Normal-Open-or-Close-Switch-KW12-3-p-1896962.html The case for the ESP32 Cam is as small as possible. The backplate is to be done including an holder for it. there is an other part wich will hold the power board for the cam and a relais to switch the power off. It consists o two pcbs which had lucily the same length. I put them side by side and connected the 5V (adjusted) output to thi underside of the relais board.

The programming board for the cam is still be able to be plugged in. I hope that I'll have the time to continue the work soon.
