I changed the Servo Period to 1000000, no change.

Is it typical for the default values from PncConf to be non-functional? Because that makes this REALLY tough for me to figure out.

Upon your suggestion I ran linuxcnc from the console. Sure enough the watchdog had bit! I changed the watchdog timeout from 5000000 to 10000000 and that got it working!

Thanks again for all of your help!

Now I'm in the process of checking the daughter board outputs, so I can get the last 4 steppers working.

I did some copy/paste within .ini and .hal to add more axes: x,y,z,a,b,c. With 5 axes I have no problems and everything seems as expected. When I add the 6th axis(c) the startup procedure fails. There are 5 axes on the 7i76e and the other 4 are on the 7i85s that is hooked up. All 9 step/dir outputs show up in the hmid file, so the firmware seems correct. Perhaps there's a different way to identify the pins of the other step/dir pairs?

The error code is: "./StepperTest.hal:312: parameter or pin 'hm2_7i76e.0.stepgen.05.dirsetup' not found"

The line of code from the .hal file is:
Code:
setp hm2_7i76e.0.stepgen.05.dirsetup [AXIS_5]DIRSETUP

Any clues what I might be doing wrong?

That was it. Thanks again!

I am making some great progress on my system. I've got all 9 steppers configured (mostly) and now I need to start wiring up homing and some external GPIO (controls for pneumatics, etc). But I've hit a snag...

Where can I find the pinouts for this thing?

Here is the relevant snipet from the .hal file:
Code:
# external output signals # --- DOUT-00 --- setp hm2_7i76e.0.gpio.034.is_output true net dout-00 hm2_7i76e.0.gpio.034.out # --- DOUT-01 --- setp hm2_7i76e.0.gpio.035.is_output true net dout-01 hm2_7i76e.0.gpio.035.out # --- DOUT-02 --- setp hm2_7i76e.0.gpio.036.is_output true net dout-02 hm2_7i76e.0.gpio.036.out # --- DOUT-03 --- setp hm2_7i76e.0.gpio.037.is_output true net dout-03 hm2_7i76e.0.gpio.037.out # external input signals # --- HOME-X --- net home-x <= hm2_7i76e.0.gpio.017.in # --- HOME-Y --- net home-y <= hm2_7i76e.0.gpio.018.in # --- HOME-Z --- net home-z <= hm2_7i76e.0.gpio.019.in # --- HOME-A --- net home-a <= hm2_7i76e.0.gpio.020.in # --- HOME-B --- net home-b <= hm2_7i76e.0.gpio.021.in # --- HOME-C --- net home-c <= hm2_7i76e.0.gpio.022.in # --- HOME-U --- net home-u <= hm2_7i76e.0.gpio.023.in # --- HOME-V --- net home-v <= hm2_7i76e.0.gpio.024.in

How do I find out which pin is hm2_7i76e.0.gpio.017.in?

Here is the info from the 7i76e firmware:
Code:
hm2/hm2_7i76e.0: Smart Serial Firmware Version 43 hm2/hm2_7i76e.0: 51 I/O Pins used: hm2/hm2_7i76e.0: IO Pin 000 (P1-01): StepGen #0, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 001 (P1-14): StepGen #0, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 002 (P1-02): StepGen #1, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 003 (P1-15): StepGen #1, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 004 (P1-03): StepGen #2, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 005 (P1-16): StepGen #2, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 006 (P1-04): StepGen #3, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 007 (P1-17): StepGen #3, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 008 (P1-05): StepGen #4, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 009 (P1-06): StepGen #4, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 010 (P1-07): IOPort hm2/hm2_7i76e.0: IO Pin 011 (P1-08): IOPort hm2/hm2_7i76e.0: IO Pin 012 (P1-09): IOPort hm2/hm2_7i76e.0: IO Pin 013 (P1-10): IOPort hm2/hm2_7i76e.0: IO Pin 014 (P1-11): IOPort hm2/hm2_7i76e.0: IO Pin 015 (P1-12): IOPort hm2/hm2_7i76e.0: IO Pin 016 (P1-13): IOPort hm2/hm2_7i76e.0: IO Pin 017 (P2-01): IOPort hm2/hm2_7i76e.0: IO Pin 018 (P2-14): IOPort hm2/hm2_7i76e.0: IO Pin 019 (P2-02): StepGen #8, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 020 (P2-15): StepGen #8, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 021 (P2-03): StepGen #7, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 022 (P2-16): StepGen #7, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 023 (P2-04): StepGen #6, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 024 (P2-17): StepGen #6, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 025 (P2-05): StepGen #5, pin Step (Output) hm2/hm2_7i76e.0: IO Pin 026 (P2-06): StepGen #5, pin Direction (Output) hm2/hm2_7i76e.0: IO Pin 027 (P2-07): IOPort hm2/hm2_7i76e.0: IO Pin 028 (P2-08): IOPort hm2/hm2_7i76e.0: IO Pin 029 (P2-09): IOPort hm2/hm2_7i76e.0: IO Pin 030 (P2-10): IOPort hm2/hm2_7i76e.0: IO Pin 031 (P2-11): IOPort hm2/hm2_7i76e.0: IO Pin 032 (P2-12): IOPort hm2/hm2_7i76e.0: IO Pin 033 (P2-13): IOPort hm2/hm2_7i76e.0: IO Pin 034 (P3-01): IOPort hm2/hm2_7i76e.0: IO Pin 035 (P3-14): IOPort hm2/hm2_7i76e.0: IO Pin 036 (P3-02): IOPort hm2/hm2_7i76e.0: IO Pin 037 (P3-15): IOPort hm2/hm2_7i76e.0: IO Pin 038 (P3-03): IOPort hm2/hm2_7i76e.0: IO Pin 039 (P3-16): IOPort hm2/hm2_7i76e.0: IO Pin 040 (P3-04): IOPort hm2/hm2_7i76e.0: IO Pin 041 (P3-17): IOPort hm2/hm2_7i76e.0: IO Pin 042 (P3-05): IOPort hm2/hm2_7i76e.0: IO Pin 043 (P3-06): IOPort hm2/hm2_7i76e.0: IO Pin 044 (P3-07): IOPort hm2/hm2_7i76e.0: IO Pin 045 (P3-08): IOPort hm2/hm2_7i76e.0: IO Pin 046 (P3-09): IOPort hm2/hm2_7i76e.0: IO Pin 047 (P3-10): IOPort hm2/hm2_7i76e.0: IO Pin 048 (P3-11): IOPort hm2/hm2_7i76e.0: IO Pin 049 (P3-12): IOPort hm2/hm2_7i76e.0: IO Pin 050 (P3-13): IOPort hm2/hm2_7i76e.0: registered

But for the life of me I can't figure out how to map the pins or the (P3-01) to the actual terminal block. It doesn't help that the 7i76e manual seems to have an entirely separate naming convention.

What am I missing?
