Hello to all.
I need to control a screw with an encoder mounted on it. Calculating the
max rpm and the resolution I want I need a 25 khz read response for the
encoder.
I remember reading somewhere the maximum expected frequency of the parport
software driver to read an input but I don't remember

Hello Jon and thanks for the quick answer.
I was affraid that it would be on the limit. I guess I'm going to use a
5i20 to read it. I have one machine using it so I can test it with the TTL
encoder and see how it works.
Do you know if the 6i25 is already supported by LinuxCNC? I know that

Just to inform about this problem I had with trying to make parallel card work

Do you have the addf parport.N.write base-thread line for each port?
Yes, Mesa 5i25 + 7i76... you can swap the 7i76 for a 7i77 when you
change to servos.

EPP mode is used _only_ by specific Mesa or Pico Systems I/O cards,
which provide a lot more than 17 I/O pins on each parport. Take some

I was looking for Mesa combination with 5i25 + daughtercard but I need outputs
for 6 steppers because of gantry construction of machine frame. 7i76 has 5
dedicated outputs. Can I use other outputs for motor as well?

You can have two 7i76 cards on one 5i25, just don't forget to ask for
the header adapter for the second one. And also make sure you use the
proper parallel port cable (easy is to just get them from Mesa). This
combo makes a very neat install with only one (or two) cable from
computer to drive

The default 5I25 config when used with the 7I76 is a dual 7I76

Kirk,
I got the bash script working just in time to move on to using classic
ladder... :) It turned out to be the parport.1.pin-2-out vs
parport.1.pin-02-out 02 fixed it.

I have got problems with linking pins with classicladder.
Could you give me an example with input and output.
I will have pins 2 - 13, 15 input and 1,14,16,17 outputs;

I have configured emc for parport setup as output, however when I measure

hmm, but something with step and direction signals has only one half

Therefore my design takes quadrature output of EMC, puts it into QENC
