Added a bit more to the controls:
- 10A Breaker between VAC in and power switch.
- Neon A/C power indicator light.
- 10mm LED indicator for Machine Enable.
- 120mm 115VAC Fan.
- Picked up an E-Stop mushroom switch.
I got a few more DIN terminal blocks, colored for clarity, for the AC terminals. I need a few more green for the grounds and some more red, yellow, and black terminals for the 2nd tier sub panel.
The fan is a little funny. It certainly moves the air, but it's pretty loud. I can feel the air movement across the table from the fan !
I was able to get enough of the LinuxCNC/MESA system up to confirm basic operation. There is no graphical method to generate the HAL and INI files for a MESA 7i92M however the 5i25 is a very similar device just accessed via PCI instead of ethernet. I was able to come up with a pretty bare bones 5i25 based configuration and simply modify a few lines for the 7i92. I connected the MESA card with a straight through ethernet cable and used the default IP of 192.168.1.121/24 for communication. First I used the mesaflash utility to push the firmware for the MX4660 to the card. Then I fired up the LinuxCNC config for this system and it came right up. A quick check of the X step pin with a multimeter HZ counter showed the correct pin was being pulsed as the X axis was jogged. Should be fairly simple to build up the rest of the system I/O from this point.
Next month I will have the NUC PC for the controls and can make a pretty good run at getting the main controls up and running.
