Re: [Emc-users] M101 - M199 problem
Because of this I also tried a bash script
that called the C program and got the same result (no response). Both work
from the command line. I get no errors from EMC2.
I have entered a echo command in the bash script that is shown when I run it
from the command prompt. When run from EMC2 should it appear in a terminal
window?
Hi
I think you are heading down the classic ladder path to achieve your
overall end, but I don't recall seeing your having solved the initial
problem of executing scripts etc from a M1XX command.
I had some problems getting hal commands to run within a bash script
called from M1xx, a while ago.
First off, unless your controller computer is permanently connected to
the internet, (why would you, hardly going to improve latency) just log
in as, install as and run everything as root.
Sorts out all the problems with permissions, ownership etc. The
'middle-man will get you' paranoids will argue against it, but for a
stand alone computer, I really do not see the problem.
Obviously ensure that M1xx file is in the path pointed to by
PROGRAM_PREFIX in your .ini file
If somehow you have 2 entries in your .ini file, EMC only reads the
first one.
Wonder how I found that out!
If you launch EMC as child process within a terminal (ie without the
trailing ) you will get stderr etc from emc and any processes launched
from within it, eg bash or your C program.
It was seeing this and using debug outputs, that enabled me to discover
that EMC reads M101 P3 and then passes 3.00 instead of just 3, to my
M101 script!
As an example the below M101 script uses calls to halcmd to adjust the
scale and stepgen associated with my spindle, to account for pulley changes.

Re: [Emc-users] M101 - M199 problem
I would like to respectfully disagree.
I do not see why one needs to run as root just to solve basic
permissions or path issues.
And I also do not see why being on the internet is going to ruin latency.
Additionally, being on the internet would enable one to get system updates.

I have to agree with Igor here. Emc runs as well from a user account as it
does from root, permissions problems are, with all due respect, usually
caused by mucking about in the user account while root. We call that
PEBKAC.
AND the machine being on the internet has no apparent/detectable by me
effect on latency. I have had konversation going and logging the emc
channel, browsed the web (usually to the emc wiki pages for coding help)
and or edited gcode, all while my machine was busy carving something. And
its only an XP1400 runing at 1600 mhz, with half a gig of ram.

[Emc-users] M101 - M199 problem
Hello, I am having a problem getting a custom M101 to work. I building a custom tool changer and I am controlling it with an arduino board. I need to send a BCD signal over a spare parallel port. I have a C program that accomplishes this and I can make it work by running it from a terminal. I do however need to run it with sudo. Because of this I also tried a bash script that called the C program and got the same result (no response). Both work from the command line. I get no errors from EMC2. The spare port is not used by EMC2. It is actually the port on the mother board. My machine is running off a PCI parallel port card. The files are also in the appropriate directory. I have entered a echo command in the bash script that is shown when I run it from the command prompt. When run from EMC2 should it appear in a terminal window? I realize I could use classic ladder to accomplish this as well but I don't see why this is not working? Any help would be greatly appreciated.

Re: [Emc-users] M101 - M199 problem
Try this: go to your directory with all G code functions etc (program_prefix). Then: ( echo '#!/bin/bash' echo 'echo date /tmp/M156' ) M156 chmod 755 M156 then call M156 from EMC2 Then look at file /tmp/M156 On Sat, Oct 2, 2010 at 8:57 PM, Mike Cinquino mcinqu...@gmail.com wrote: Hello, I am having a problem getting a custom M101 to work.
