One should always RFTM, it's a good practice to follow unless you are quite financially well off, have plenty of time to spare and have the patience of a saint.

Or some other poor sod is setting everything up and you have 100% trust in them.

Do you have a link to the drive manual or at least the the I/O connections?

You can use MesaCT to generate 7I97/7I97T compatible configurations
plus theres a sample 7i97/7i97t configuration. I think this is in the 7I97T
software support zip file, if not, I can post it here.

Yes, that should be correct.

Thx, this is how my setup looks like... 



So if I understood your answer correctly - I replace R1 (currently 10k) with 110k, which gives me 10k (110k & 11k in parallel). 
Will try that tomorrow....

thx!!

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

The code in my hal file is now
# --- SPINDLE-AT-SPEED ---
net ext_spindle-at-speed <= hm2_7i76e.0.7i76.0.0.input-12
setp lut5.0.function 0x0d
net spindle-enable lut5.0.in-0
net ext_spindle-at-speed lut5.0.in-1
net spindle-at-speed lut5.0.out

if I use hal meter to view the pins on lut5.0 the inputs have the expected values depending on whether the spindle is on or off and whether it is up to speed or not, but the output is always false.

What am I missing?

thanks unknown,  Sorry.  Enough said.    Eventually i wanted to try and get this arm under LinuxCnc control,   So a tiny bit on topic,   maybe i should have led with that.   or started a new thread . 

my servos, BOB, and power supply should be in by the end of the week.   I have been reading about the HAL, and the stepconf wizard.
 I will be using the clearpath SDSK-2321S-RQN  DC servo

i am trying to read up on the  stepconf wizard?    that is next  , and  i need to  read the servo manual as well

thanks
