UV LED CONTROL
Posted: Thu Feb 22, 2018 5:09 am
Hi guys. I´m from Spain and I´m searching information about building my own LCD UV SLA printer.
I have a million of doubts, but at the moment I only want to solve one.
I want to build it with a rapberry pi 3 conected to a ramps 1.4 and Mega 2560 ( I have someone in house without use) and controll it with nanoDLP software. I imagine the motors and other parts will be controlled by Marlin like an FDM printer, but that it´s not my doubt now (there will be another time for that)
I want to know exactly how the UV LED is controlled ( how and where is connected to turn on/off LED when slicer send to lcd panel the layer ) because that control in origin is in the LCD board, but I don´t know how to find the signal to control and external LED.
This is the only question that stop me to start the project.
Thanks in advance for all and I hope in future I can solve you any doubts.
Thanks again.
