I made my first m101 program for my lathe today. I wrote a g-code file to test the turret setup:
% m64p1 (turn turret rotate solenoid on) g4p.2 (wait 200ms) m64p2 (turn turret stop solenoid on) g4p.2 (wait 200ms for turret to slow to stop) m65p1 (turn turret rotate solenoid off) g4p.2 (wait 200ms for turret to descend and lock) m65p2 (turn turret solenoid off) % This worked very well to rotate one tool position. The next step was to move this to m101. So I created an m101.ngc file containing: #!/bin/sh halcmd sets TurretRotate True sleep .2 halcmd sets TurretStop True sleep .2 halcmd sets TurretRotate False sleep .2 halcmd sets TurretRotate False exit 0 Then I removed the motion.digital-out-01,02 links from the io.hal file. This script also worked well, but I am concerned about the "sleep" function. It is a user space function and is susceptible to delays, which would not be good. Can anyone can suggest a realtime version of sleep? Next, I'll add the tool position feedback. I guess I will assemble the four input bits in the shell script to make a nibble. Then compare it to the requested position. Start the turret rotation and monitor the position feedback. When the turret position matches, I'll invoke the stop sequence, check the turret locked status bit and either exit or error. Is it typical to have a XZ position feature for the turret change, or is it assumed that the operator has insured that the turret will clear any obstruction? It seems that python would be good for this script. I started studying this link: http://docs.python.org/tut/tut.html I don't know nearly enough to use it for this script,but maybe the next one.
