Hello, I bought a C10 BOB and a C36 relay board from CNC4PC that I'm using on Port 2 of the Smoothstepper, on Port 1 I'm using a DMM-Tech BOB because I'm using servos for my new CNC router.
I'm using a Smoothstepper because I use a laptop with Mach3 so I don't have LPT port.
My problem is that when Mach3 is running, the outputs are working fine, but when I shut down Mach3, the BOB's energizes the outputs. As soon as I boot Mach3 again, it shut the outputs off again and are working fine.
What's the problem?
It's very dangerous because the outputs are working always when I switch on the power supplies for the electronics, then with Mach3 working, the outputs are working well and I can switch on and off without problem, but when I shut down Mach3, the outputs are on again.
These are the BOB's:http://cnc4pc.com/Tech_Docs/C10R10_USER_MANUAL_V2.pdfhttp://www.dmm-tech.com/Files/Mach3Configuration_v01.022.pdf
