Record g-code live. was created by dab77
Hi, I just managed one way to record the teleop joystick manual movements into a g-code program.
I know maybe is not anything useful for cnc'ers, but i write here just for the sake of knowledge..
I wrote a handler into python that is called when one button on my joystick is pushed. This function open a file and append into it
the speed, xpos,ypos and zpos every "interval", i.e. every second.
output is like this:
G1 F 'speed' X 'xpos' Y 'ypos' Z 'zpos'

for the timing i use this routine:
prev_time = time.time()

def on_recording:
if (time.time() - prev_time) > 1:
write_into_your_file
prev_time = time.time()

I still need to find a clever way to add at the end an M2. maybe wasting another joystick button..

Any other suggestion or comments are welcome.
Davide.

Does teach_in.py do that? (Does it do anything? I have only ever seen the filename :-)
git.linuxcnc.org/gitweb?p=emc2.git;a=blo.../scripts/teach-in.py
Hmm, no, it seems to output positions, but not in G-code.
