I wonder what made you think you need to do that ? There is no need for anything under that line, just boot and use as live, or install to hard drive and start Linuxcnc.

I am installing from a USB thumb drive to a 64g SanDisk card. Going with no HD in the Zotac.

I will take a look at that.

I am newish to Debian flavored ice cream. Kinda avoided it as much as Wondoz. Not new at all to Linux but that never means I don't learn something everyday

I tested/verified the 5v source that was going to the C10 and sent that to the 7i76e P3 plug.

I am now onto where I run out of talent and onto remove/replace.

C10 has the following set on the jumpers.

• COM 1-2 GND # I'm Ok here
• Pins 2-9 Pull down # I honestly do not know at this time what pull down/up means.

The 7i76e has something extra from the C10 that I am not getting.
Pin 1 GND # I am Ok with that
Pin 2 STEP0-
Pin 3 STEP0+
# I am stuck...
Pin 4 DIR0-
Pin 5 DIR0+
# I am stuck....

Step and Dir the - + option.

I am going with +, it sounds so much better than - today.

I wont throw the power till I understand this better.

Any advice is totally welcome.

just a guess as you aready got the main thing done and the mach3 config importer will do that all for you

Is the + - on the 7i76e board essentially giving a hardwire physical option for direction rather than software?
