Lcnc axis needs to grow the ability to put more labeled check boxes on the left, control panel, just for such uses.

The actual control is by switching a charge pump, which results in about 500 ms lag. Seemed better than having the vacuum come on when lcnc was stopped. The charge pump detector in turn drives a ice cube to switch half of a duplex. > Also, if there is any type of feedback line, you could try putting a > pressure regulator in line, or maybe a delay circuit/relay in the > path.

The pressure switch, with a huge mechanical hysteresis I can get at TSC, and if the tire pump ever gets assembled, would be used as the pressure tally. > Also, isn't there some way to access any GPIO pins external to the > main controller?

Someone probably has. :) But I am nearly out of gpio on that 5i25 as both ports are hooked up now, and if I ever put a rotary table on it, I'll have to move whats gpio on p3 since there doesn't seem to be a way to specify where (p2-p3) another stepgen would appear if enabled. The config has an A axis, commented put because I needed the gpio for something else, home switches maybe as I had not at that point added a bob on p2. I need to change my style, and put gpio useage starting at the top of p2. Thats what I am doing with the 7i90 on this lathe. gpio stuff, like the controls for the SpinX1 for the vfd, are all on the top end of P3, at gpio.071, 070, and 069. So I can add all sorts of stuff w/o haveing to rewire stuff later. > Anyway, hope that helps.
