Hi Peter
Thanks for responding.
I have the Macropump and M100 working well as per the M100 Modbus Interface Unit Users guide. That you authored.
All I wish to do is to use some spare I/O pins to extend the little router with additional sw's and output to relays on Dotxx.?
Then add a brain or two to involve M Codes.
Brains I have working o SS I/O but nt the M100
Reading page 26/7 I should be able to use Mach inputs/outputs on Port 0 and pins 0 to 7.
When I do this I get errors "port 0 must be on Smoothstepper."
Trying to find a work around has been un successful.
Can you offer an approach that will work?
I would prefer to stay with the micropump as this system is working and I don't see how I can use the alternatives with your pendant setup when you reaalise mine interpretation is different to the Plugin dictates.
Regards
Graham
