extra axis on 7i96 with bob

hello, I have a working config on my cnc machine using a 7i96 (no s) thats using 4 stepgens and pmw output for the spindle and it's been working greaat for a few years now.

I need the four stepgens to square up the gantry (XYYZ kinematics) and I am looking at options to add a 5th stepgen to drive a rotary axis using a chinese Bob connected to the P1 expension port.

Am i correct it seems the simplest is to move the spindle pwm control to the BOB to use the 5 stepgens directly on the card?
what firmware would i need to flash on the card, and is there a exemple config that displays how to drive the spindle pwm output from the BOB? 

thanks for the help

If this is the standard SainSmart V2  5 Axis BOB, then
7i96_5abob_d.bit firmware would be the appropriate.

The existing hal file should be close (the PWM output just moves
to the BOB) There may be polarity/frequency changes needed
with the PWM output.

You would need to add the 5th axis stuff to the hal/ini files

thanks for the answer, I tried flashing the firmware with mesa flash and all I get is "no 7I96 board found"

adress is 10.10.10.10,

running --device ethernet-- returns "ETH device 7I96 at ip=10.10.10.10"

any idea what that could come from?

What command line did you use?

Something like:

mesaflash --device 7i96 --addr 10.10.10.10 --write 7i96_5abob_d.bit --reload

should work

mesa flash version 3.4.6

I tried adding --reload but i still get the same answer, I also tried using 7i96_2

Did you add the "--addr 10.10.10.10"
 

yes I ran your exact command

Strange, does:

mesaflash --device ethernet --addr 10.10.10.10 --write 7i96_5abob_d.bit --reload

work?


 

"no ethernet board found",

I must admit I am not super linux savy, could i be doing something wrong related to either the boards' jumper or some other config related issue?
