Subject: [Emc-users] Linuxcnc configurations using Mesa
I have a D525MW that I was using to drive my PCBMill. It got some chips
in the controller box and shorted out the BOB and apparently damaged the
parallel port slightly. Other than the parallel port the D525MW seems to
run fine. I replaced the BOB in the controller box but it still didn't
seem to run correctly. I am not positive whether it is a drive or the
parallel port that is damaged. I finished a new controller cabinet for
my PCBMill with a Mesa 7i76e. On my PCBMill I am getting lots of read
and write error messages with Linuxcnc on my Rpi4 with the 7i76e. On my
CNCLathe, I have a Dell Optiplex 330 running a 5i25/7i76 pair. Is it
feasible to replace the 5i25/7i76 pair with the 7i76e? I also have a
7c81 mesa card. On my PCBMill could I use the Rpi4 with the 7c81 to
drive the 7i76? Do these changes make any sense? I don't want to screw
up my CNCLathe, it runs fine right now. However, I would like to get my
PCBMill running more reliably.

If you get read errors on a RPI4 and 7I76E, I would double the servo
thread period (the RPI4 is marginal at a 1 KHz servo thread period with
some kernels)
