Hi,
I built my mpcnc with Arduino UNO (+ CNC Shield V3) and I use the Estlcam controller. I bought a 1.5 kw spindle and an inverter. I ask for help because I can’t do the wiring between the inverter and the cnc shield to control the inverter directly with Estlacm. Does anyone teach me what to do? which pins to connect?
I attach the photograph of my inverter.
You’re moving into uncharted territory here. As far as I can remember, no one on this site has done this before.
Hopefully someone can come along with experience with both ESTLCam and that type of spindle controller and help you out.
Hopefully that controller came with some documentation… It looks to me like the red 5V IN, 12V IN and 20mA IN are used to set your speed, you choose whether to use 0-5V, 0-12V or 4-20mA as your control signal. I’d think the 12V OUT is your power for the spindle and GND is shared between all of those.
thanks bill
