Secondary spindle on 7i76e
7I85 on P1
Mach 5ABOB on P2
PWM on DB25 pin 1
4 new stepgens on DB25 pins 2..9
all other P2 pins GPIO
Is this W12 to be changed? Pins 18-to 25 are ground in pport db25 so I do not get this.
This option should only be enabled
for Mesa breakout boards or boards specifically wired to accept 5V power on DB25 pins
22 through 25. When the option is disabled DB25 pins 22 through 25 are grounded.
Jumper W7 controls the power option on P1, W12 controls the power option on P2.
