Mesa 5i25 step by step configuration

Aha,

I've just learnt something.

I have never looked at the card its a 6i25 with 7i77x2.bit loaded.

I have attached the mach 3 xml file but please have a look at the zero3 manual attached.
I would like to use the pins 14,15,16, and 17 as well.

I want to use the additional cable/bracket hardware kit connector for reading my encoders on a second port that I still need to fit.

Thanks allot.

The first step required is to reprogram the FPGA with the appropriate bitfile for the DMM BOB:
5i25_dmmbob1x2.bit
This is done with the mesaflash utility:

sudo mesaflash --device 5i25 --write 5i25_dmmbob1x2.bit
sudo mesaflash --device 5i25 --reload

then you can check the pinout with:

sudo mesaflash --device 5i25 --readhmid

if not there already, mesaflash is installed with

sudo apt-get install mesaflash

and 5i25_dmmbob1x2.bit is available in the 5i25.zip support file from Mesa

( in configs/hostmot2/ )

Ok if flashed the card.
What's next.

The next step is to make a hal/ini file suited to the 5I25 card/daughtercard

There are a couple of different ways to do this

one is to start with a close pncconf created file pair
( The DMM bob is not directly supported but the probrfx2 is quite close so a pncconf created file set
using the 5i25/probrfx2 template should be close enough to get started with )

The other way is to start with the hm2-stepper sample config (and ini file)
I dont think there is a 5i25.ini file sample but you can take a 5i20.ini sample and just change the
card and file names.

I'll give it a go.

I'll let you know in a 12 hours.

Nope no luck.
