TOPIC: M100 to M199 User Defined Commands

M100 to M199 User Defined Commands 15 Jun 2012 23:36 #20986

Checked the instructions in the user manual for setting up for
M100 to M199 User Defined Commands. Copied the examples
and tweaked them for the port and pin I wanted.

M101 contains
#!/bin/sh
# file to turn on parport 1 pin 09 to open the collet closer
halcmd setp parport.1.pin-09-out True
exit 0

M102 contains
#!/bin/sh
# file to turn off parport 1 pin 09 to open the collet closer
halcmd setp parport.0.pin-09-out False
exit 0

These are executable and is in the correct directory
PROGRAM_PREFIX = /home/me/emc2/nc_files

But when I step through my test G code
G0 X-0.25 Y0.25
M0
M101
G0 X-0.5 Y0.5
M0
M102
G0 X-0.0 Y0.0
M2

HAL Meter shows no change on parport 1 pin 09
So what is missing???

Hi

Without your .hal file hard to guess.

Is parport.1.pin-09 an out pin, or was that second parport set up as "in"?

Is parport.1.pin-09 already linked to a signal?

See
linuxcnc.org/docs/2.5/html/hal/basic_hal...setp_a_id_sub_setp_a

M101 and M102 seem to be writing to different parports. I suspect that is an error,

Parport 1 is set for OUT and pin 09 is not linked to any other pin or signal.

Is there a posablity that I have to tell the Linux OS that it's OK to execute
these bash files?

YOU are absolutely RIGHT !!! What a blunder, I should not be writing this
stuff at 1:00 AM.

Thanks much
