Hello
I have a Hobby CNC Pro 4AXIS controller board. I need connect some optical switches for homing, also I need connect a SSR to start/stop router and dust extraction.
ABOUT OPTICAL SWITCHES
My optical switches were in a dot printer, the are 3 leads ( Electrical Supply,Ground,and Input pin).
Where in board can I take a electric signal for energize optical switch
Its necessary set a Resistance between electric source and input pin selected for home switch?
How tells Mach than this is an output for X electric value for Optical Switch
ABOUT OUTPUT PINS AND MACH
In Hobby CNC Pro Controller are output pins holes but are not connected , attach image.
Can I solder a connector in output pins holes, to attach a SSR?
Where can I take a ground connector?
Can I connect a SSR directly to any output?
It's neccesary connect a Resistance between output pins and SSR?
How tells Mach than M8-M9 commands do a job in selected pins?
Thanks a lot in advance.
Sorry my bad English. Hope you understand.
Regards
Rene
