Hi there,
I got a nice scanner head (not the china 70 Euro ones) with a f 430 Theta lens. Using an Arduino Mega & an additional bipolar circuit with a 12 bit DAC and 2 opamps I am able to paint nice and clear pictures.
Now I want to marry the galvos with RAMPs but I don't have any clue how to wire it up. What I basically need is to get the -5/GND/+5 signal (for Y and X axis) from the RAMPS board to control the galvos.
Found a lot of helpful information in the board about using RAMPS with galvos but not that specific information. In some therads there was said that the signal was taken from the Arduino via SPI (what my setup does too). But once the RAMPS board is connected to the Arduino all connections are blocked by the shield. Any documentation I missed?
EDIT: I noticed the SPI port on the RAMPS board but it is being used by the adapter for the display.
I am working on a SLA Printer with a build volume of 300x300x1000 mm
