With the basic core electronics functional, I started digging into the basic I/O of the machine.
The Y home switch was not functional only the limit switch was working. I replaced it with the slow down sensor from Z (nice to have a spareā¦). The entire housing was full of grease and grit, and the switch would not open. Now the housing is clean, sealed and operational. The X Y and Z Home switches are all functional and interfaced to Mach3, connected as Normally Closed for best noise immunity.
I had some issues with the M1 and M12 ModBus boards, I think it was the serial interface hardware that was not functional. I have used CNC4PC products over the last 7 years and never have had an issue. I talked Arturo Duncan and he is taking care of us. I should have a functional ModBus I/O system up and running soon. The ATC Pneumatics and Sensors will be hook up this I/O System, so for now the ATC is on hold.
Thanks,
