Hi,
clear all the outputs in the Mach Control plugin OutputSignals page.
What you are doing is assigning pin 2 as Output#1 in one plugin and as X Step in the UC100 plugin.
So which plugin has control of the state of the pin? If the UC100 motion plugin requests that pin 2
pulse on and off to cause the motor to work and yet the Control plugin commands Output#1 to be 0,
who wins?
