Configuring endstops in series - Error troubleshooting was created by MacLaddy
Hey folks,
I've been working my way through a new installation for an XYYZ PNC machine with a single parallel port. I have four inductive sensors for homing and endstops. One each for the X and Z axis, and one for each motor on the Y-Axis.
I'm not sure if these sensors are NO or NC. I have wired them in series where they remain at 24V until triggered, and then go to 0V. They are wired with X and Y1 together and Z & Y2. I have used Pin 10 for one set and 11 for the other.
Here's the issue. When I start LinuxCNC, I receive the following error. I'm not sure what it means. I've been able to work my way through several previous errors and the HAL/INI file, but this one has stumped me.
I appreciate any help offered. I just started with LinuxCNC, so please be gentle. I've also attached my HAL and INI file.
Afterthought: I realize many of the travel distances and velocities are out of whack (8 inches or so). I'll fix those once I can get the program to boot.
C from starting.
More information may be available when running from a terminal.

Just a a WAG but maybe the error:
emcMotionInit: emcJointInit(3)) failed
is because of the broken number in joint 3:
HOME_LATCH_VEL = 0.03 0000
emcMotionInit: emcJointInit(3)) failed

It worked! Excellent WAG. I never would have noticed that white space, thank you. Now I just need to see if the homing sequence actually works.Just a a WAG but maybe the error:

It is pinpointed exactly where the issue is, namely:There can be no spaces there.
This reminds me, the second time i used LinuxCNC or EMC2 back then, wasted about an hour chasing why a new config is not starting, turned out a space in a config folder name was not allowed back then.
Just squash them one by one as they come.
P.S.
Almost forgot, welcome.

Thanks for the welcome. I have no doubt I'll be here a lot. Also never heard of Nero3D. Looks like a great channel. Appreciate the tip.
(I destroyed that quoted reply. Guess I need to also learn how to use this website)

I provided incorrect information in the original post. Pins 10 and 11 remain at 0V until triggered, then go to 24V. I mention this because although LinuxCNC now boots for me, when I start the homing sequence it does not see it when I trigger the endstop. The z-motor just keeps spinning. I've tested the pin with a volt meter and I can see it goes high when I trigger it.
I have tried both :
net home-x-y1 <= parport.0.pin-10-in-not
net home-z-y2 <= parport.0.pin-11-in-not
and
net home-x-y1 <= parport.0.pin-10-in
net home-z-y2 <= parport.0.pin-11-in
Neither of these work. Is there another setting for this?
Thanks again.

Change when you manually trip the switches?
If you are running Axis you can view these with halshow (Machine --> Show HAL configuration --> Watch )

I changed them back to pin-10-in. I don't understand what you mean by "change when you manually trip the switches?" The motors are off the machine right now. I'm doing benchtop tests, so I start homing inside LCNC and manually trigger the Z-Stop since it is first in the sequence.
Thank you for the tip on viewing halshow. When doing this for PIN10, it shows parport.0.pin-10-in as red and parport.0.pin-10-in-not as yellow. They flip when triggered. PIN11 does the same. I'm pretty sure it is wired correctly, as either X or Y1 can trigger the change (but not at the same time). But it still doesn't register when homing.

The shared home signal names don't match so there
is no connection from your hardware to LinuxCNC:
net home-x-y1 <= parport.0.pin-10-in-not
net home-z-y2 <= parport.0.pin-11-in-not
...
net home-x => joint.0.home-sw-in
net home-y1 => joint.1.home-sw-in
net home-y2 => joint.2.home-sw-in
net home-z => joint.3.home-sw-in
should be something like:
net home-x-y1 => joint.0.home-sw-in
net home-x-y1 => joint.1.home-sw-in
net home-z-y2 => joint.2.home-sw-in
net home-z-y2 => joint.3.home-sw-in

net home-y1 => joint.1.home-sw-in
net home-y2 => joint.2.home-sw-in
net home-z => joint.3.home-sw-in
should be something like:
net home-x-y1 => joint.0.home-sw-in

net home-z-y2 => joint.2.home-sw-in
