Redirect output from any command to file

demonlibra

Starting with firmware 3.4 the output from an echo command can be redirected to a file.
Is it possible to redirect output from any command to file or get last output from object model?

E.g. I write code to get state of TMC registers and want to save result to file.

var driver_number=0              ; Driver number

var register_start=0             ; Start (0 ... 127)
var register_end=127             ; Finish (0 ... 127

G4 S3
if (var.register_end<=127) & (var.register_start>=0) & (var.register_end>=var.register_start)

   var counter=var.register_start

   while var.counter<=var.register_end
      M569.2 P{var.driver_number} R{var.counter}
      set var.counter=var.counter+1
      G4 P200

Assuming you can get the info from the object model..,
You can use

echo >"myFile.txt"

to create the file and then

echo >>"myFile.txt" "Register",iterations, "=", myVariable

To append to it.
Put the former before your loop and the latter inside it

If you can't get the data from the object model, perhaps try logging

M929 P"testfile.txt" S3
while iterations < 10
  M913
M929 S0

@owend Loging work fine. Thank you.

   var counter=var.register_start
   M929 P"tmcregisters.txt" S3
   while var.counter<=var.register_end
      M569.2 P{var.driver_number} R{var.counter}
      set var.counter=var.counter+1
      G4 P200
   M929 S0
