Driver Question Half the Servos Work 7i33 / 7i43 was created by jsflanagan
This should be an easy one as surely I've missed something obvious! After stealing the 7i43 from my mill to get my Hardinge Lathe all up and going I finally ordered a replacement 7i43 for my mill. The only difference was my new 7i43 is a 400k gate, the old one was 200k. After getting things hooked back up only the 7i43 was changed along w/ my IO board, I went to the 7i37TA from the non TA version. The servo board was never unhooked so I know all of the wiring should be just fine. Now only one of 3 encoders are showing up when I manually move the axes. I did change the directory from which the SVST4_4.bit file should be loaded from to reference the 400k versions. I even re-installed EMC to the latest version (on a separate HD) just to see if it was an update. Any ideas? I tried the SV8.bit file to no avail. HAL and INI files attached.
loadrt hm2_7i43 config="firmware=hm2/7i43-4/SVST4_4.BIT num_encoders=4 num_pwmgens=4 num_3pwmgens=0 num_stepgens=0 "
Thanks,

I would check the obvious things first:
5V ok at 7I33?
encoder signals ok at 7I33 inputs?
encoder signals ok at 7I33 outputs (FPGA pins)?

Turns out I had some weird wiring issue. Fixed that everything worked as normal.
