As to your 2 vs 3 axis problem in Pnconf, I suggest that you use the 3 axis set up, just put dummy info in for the Z. It will be easier to go back and comment out unused Z info, than it will be to convert a lathe config to a 2 axis mill setup. Plus to have Z axis DRO capability, you will have to have Linuxcnc think there is a 3rd axis, It just won't be able to control it.

Anyway.... The problem is that the system is not seeing the 7i77 analogout.0 pins.

This might well be due to not having field power supplied to TB1, or possibly lack of logic power (I don't actually know what powers the analog outputs).

This is a rather important section from the manual:

"VIN POWER SOURCE
The isolated field I/O on the 7I77 runs from a switching power supply that can be
powered by field power or a separate supply (VIN) with ground common with field power.
Normally the 7I77's VIN will be powered with field power. An on card jumper, W1 allows
VIN to be connected to field power. If you wish to use a single power supply for the 7I76s
field outputs and field logic power, W1 should be placed in the left hand position. This
connects field power to VIN. If you wish to use a separate supply for VIN, W1 Should be
placed in the right hand position. .
CABLE 5V POWER
The 7I77 can get its logic power from the host FPGA card or from TB1. W5
determines if the 7I77 gets its 5V logic power from the host FPGA card or TB1.
If W5 is in the left hand position, host FPGA power is used and the host FPGA card
must be jumpered to supply 5V to the daughtercard.
If W5 is in the right hand position, 5V power must be supplied to the 7I77 via TB1
and the 7I77 grounds the 4 DB25 signals used for host 5V power. In this case the FPGA
card must be jumpered so that it does not supply power to the daughtercard.
Never apply external 5V power to TB1 when W5 is in the left hand position or
you may damage the 7I77, FPGA card, PC, or connecting cable
.

I have studied the Applications menu and the accessories and see no clipboard. I have Clipman, mousepad and notes, have tried them all. Clipman has the small icon in upper left, don't see how it works, won't open. Mousepad "error creating directory" read only file system, won't accept retry, or yes or yes to all when I try to copy or move to thumb drive. Notes does not do anything. Where is my problem or am I missing a program?

Thanks

Andy, W5 and W1 are in the left hand position.

Should I consider switching one of the jumpers at a time?

If you have the 7I77 Jumpered for cable power (W5 LEFT) , you need to also
jumper the 5I25/6I25 to supply cable power. This means W2 on the 5I25 or 6I25 must be UP

PCW, Many thanks for your help! When you describe "up" as when looking at the jumper positions on page 4 of the 5i25 manual, and the Mesa writing on the card is in the normal position (horizontal), currently the W2 is down, I should move this jumper as per your suggesting and re-power the system?

Many thanks!

This is the most recent error file, this code represents the W2 (jumper) is now in the up position as per comment by: PCW

It looks to be working now:

[ 151.723699] Board hm2_5i25.0.7i77.0.1 Hardware Mode 0 = standard
[ 151.726303] Board hm2_5i25.0.7i77.0.1 Software Mode 0 = analogout_enables

Your error is now:
./BridgeportLinux.hal:126: Pin 'hm2_5i25.0.encoder.00.position' was already linked to signal 'x-pos-fb'

Something funny on line 126.

Andy, I just read Todd's comment about config set up as a 3 axis mill and edit out the "z" because I will only have 2 axis.

Many thanks

That's the same error as last time, but on a different line of the HAL file

Probably worth going through the file and making sure that it is X with 0 and Y with 1 everywhere.

As has been mentioned, keep the Z and set the f-error limits _really_ high. Then you can feed a linear scale into Z-pos-fb and have a DRO on the manual Z.
