It seems as if the internal port p1 is not showing up in my pins... I'm not sure why that is

I know this is an old thread, but are you willing to share your fiber laser configs? I’m starting this project currently and curious about how you handled things like auto focus, laser pwm, etc

After the initial hick-ups with Lan connection, I hoped everything will be smooth sail, but it looks like no luck.
I tried a couple of times to install it from scratch, but same problem is there initramfs tools error code 1. Wondering why it looks for raspi when I am not running Rospi?
What can I do to properly finish with installation? 

Thanks,
M

I've recently bought a Harrison Alpha 330 with a broken computer. I am
going to convert this lathe to linuxcnc using my own motor drives.
 
Since this lathe was using a Fanuc controller and I could not find
sufficient information about the Fanuc encoder protocol, I decided to
try to reverse engineer the protocol. And it seems I have succeeded and
would like to share what I have learnt about the protocol, in case anyone
else wants to re-use their Fanuc encoders.
 
The motors present are beta1/3000 or A06B-0031-B077 (X-axis) and
beta2/3000 or A06B-0032-B077 (Z-axis)
 
First of all the code can be found in
github.com/mark-v-d/motor_control/tree/fanuc
 
Both the file software/xmc4400/src/encoder.cpp and
software/xmc4400/src/crc_lut.h should contain all
the information necessary.

   without a preceding startbit.  The way to capture it, is to change

okay I am now trying to figure out what I need to do to make the 7i74 communicate to the 7i84. it has a pwr LED on and nothing else.

You likely need a sserial_port_1=0000XXXX or similar in your hal file

it is in the righthand position for seperate field power from vin. is that vin for the logic seperate from that of the 5v vin on the left hand plug?

The VIN jumper is completely unrelated to the 5V side. Typically it should be left in the default left hand position
so VIN comes from VFIELD. If it's in the right hand position, the VIN pin on TB2 must be supplied with +8 to +32VDC

okay I am now trying to figure out what I need to do to make the 7i74 communicate to the 7i84. it has a pwr LED on and nothing else.

I misunderstood the wording in the manual. now that the jumper is over to the right it is lit up and I am making more progress with getting this thing to work.

Oh yes I see only the yellow is on. Red light is not lit on the bottom.

Do you have a red LED illuminated on the 7I77?

With 7I77 field power you should have gotten 2 new LEDs:

yellow LED CR3 and red LED CR16
(when running, red LED CR16 should extinguish and green LED CR15 should blink)

Is W1 in the left hand position?

I figure you might ask for the pinout from mesa flash so here is that.

I added 12v field power to the 7i77 but still am getting the pin doesn't exist error. I do have a new light on the 7i77 though.

The 7i77 must have field power or the field I/O pins will not be present:

hm2/hm2_5i25.0: IO Pin 003 (P3-15): Smart Serial Interface #0, pin tx1 (Output)  << 7I77 analog out is working as it needs only 5V
hm2/hm2_5i25.0: IO Pin 004 (P3-03): Smart Serial Interface #0, pin rx1 (Input)
hm2/hm2_5i25.0: IO Pin 005 (P3-16): IOPort  << This is the 7I77 digital field I/O. It's not working, likely because 7I77 field power is not present
hm2/hm2_5i25.0: IO Pin 006 (P3-04): IOPort
 

I have it hooked up to a 5 volt supply. Lights turn on. Also need to figure out how to make the 7i84 I have get detected when connected to the 7i74. The 84 has 12v field power
