"pwm/dir" (Out1) switches for spindle CCW

Category: Basic Configuration

Thanks Peter for coming by. I put your 3 lines in my .hal file but there is an error message:
...
Debug file information:
Note: Using POSIX realtime
./ttm_a.hal:298: parameter or pin 'hm2_6i25.0.gpio.007.is_output' not found
2077
Stopping realtime threads
...
Perhaps this is because  gpio.007 is "hm2/hm2_6i25.0:     IO Pin 007 (P3-17): PWMGen #0, pin Out1 (Dir or Down) (Output)"

Seems this gpio.007 is bound to "pwm/dir" (Out1) for signaling CCW, what I want to do is to use it as a signal to enable my VFD while CW rotation.
Because I'm low on outputs I want to use this gpio.007 with the relay.

Mesa 7i76eu gpio pins not working

Category: General LinuxCNC Questions

Had the same issue, need to wire the "orange block" so that your inputs and outputs have power. You should see a yellow light only with only Ethernet or 5v power..... and a red or green light with field power.

I think it's just the bottom one on that orange block that needs 24v and the top one needs ground but that's from memory.... please check the manual

Mesa 7i76eu gpio pins not working

Category: General LinuxCNC Questions

Hello,

I am using Mesa 7i76eu card to operate my 3 axis CNC mill. I connected the stepper motors and they work, I can move them with linuxCNC. Now I tried to connect PNP proximity sensors to use as homing switches, but they are not working. At first I was also getting an error when starting linuxCNC, but i noticed that is because W1 jumper fell out while wiring. I set the W1 jumper back to its original left position but the pins are still not working. I also noticed that i have a CR11 LED light turned on indicating field i/o fault. Does anyone have an idea what could be the problem.
