Hi Jeff,

Been a long time since I made contact. Well, the project is finally finished and operational, thanks to your help. I am here to tell you that it was greatly appreciated. I'm involved in some deeper aspects of design and programming of Mach3. I am currently working at attaching a commercial thread break detector that is basically an optical relay with 5 volt inputs and a spring activated ceramic coated thread tensioner that will input a voltage to pin 15 on the Rockcliff board. What I don't understand is the power supply to it. I have to work on that though. Take care buddy, I'll post some photos of the system in operation real soon.

Larry,

Please post a link to the schematic for the thread break sensor.

Hi Jeff,

here is the schematic.

Larry,

I would suggest connecting the sensor to your breakout board in PNP mode.

Simply provide a D.C. power source (15 to 30 volts d.c.) to the sensor also connect ground (black) to the BOB ground then connect the green from the sensor to an available input on the BOB.

Hi Jeff,

I was basically of the same opinion, but, you know how it is, better to measure twice and cut once, eh? Sure appreciate the opine.

Hi Jeff,

Long time no talk to. I have an issue. I blew out the magic smoke on my rock cliff 4 axis board, and I find out I can't get a new one. The only thing available from Rockliff is a 5 axis controller interface board. Looks like the pin outs are same, b ut my question is this. Will the flood/mist relay require an optical relay the same way as the rock cliff 4 axis board? Also, is there anything special that needs to be done to setup the Estop, or is it the same as the 4 axis board also?
