Many thanks to both of you.  I will try one of the solutions and let you know.

General Mach Discussion / Spindle On Off Setup No 5VDC at relay.

« on: April 27, 2011, 12:15:07 PM »

I am trying to set up Spindle on/off.  I have Setup output #1 to pin
16 and Spindle on/off to output #1.  Checked voltage on Pin 16 and GND
and I get 5VDC.  But when I hook up my relay to to it, the voltage
drops down to 0.24VDC. I am using a MDFLY breakout board (generic board) and the relay
has a nominal coil current of 89.3mA. and coil resistance of 56ohms. I
tested relay on computer 5V power supply and it works fine.  Do I need
a different relay?  Do  you know what the problem might be?

Thanks for the Info.  This site is a great resource.  I felt like I was on my own until I found this place.  I was able to get it to work.  It ended being the breakout board.  It ended up being the voltage coming from the drive to power the CNC side of the breakout board was only 50ma.  It was not enough to work it.  Now all seems to be working fine.  Thanks again for all your help.  My job is not done so I will most likely be back for more help.

Thanks.  That is very helpful.   What about the DIR.  What voltage should that be when testing it while running the jog CCW.

I am having a similar problem so I have been reading the comments for answers.  My issue is a little different.  I can get a voltage change when I jog the X.  Connected to Step,  I get a voltage change from .072 to .095.  I don't think my breakout board can read such small voltage.  I have checked TestDriver, address, offline button, reset and none of it seems to change that I really am not getting a reading worth mentioning.  Any additional help would be appreciated.
