You can use the 'task' parameter like this:

There is no way to 'unhome/rehome' a joint in gcode.
There is a modified 'orient' component that allows optional rehoming to an encoder index signal before doing the spindle orientation.
This post contains a config for spindle/rotary switching in gcode using the modified 'orient' component to rehome the spindle before switching to rotary mode. (This requires an encoder with index on the spindle)

Hello.
In my program, I use a custom subroutine where I wait for some input value to turn 1 and then continue. When I import the g code (with this function), LinuxCNC hangs and I have to kill it from terminal. Even with a simple function

o<myfunc> sub
#1 = 0
o150 while [#1 le 0]
o150 endwhile
o<myfunc> endsub
M2

and a minimal program

o<myfunc> call
M2

the import of the program hangs. As soon as I change "[#1 le 0]" to "[#1 lt 0]", it imports correctly. So my question is: does LinuxCNC execute all the subroutines even during importing of program? And since the change of value I am waiting for will never occur during import of program, what could I do? How to prevent linuxcnc from infinitely waiting in the while cycle?

Hello, I'm new here. I'm a bit of a novice. Sorry if I put the question in the wrong place.

I'm making a 4-axis swiss lathe. I've never had any mechanical problems. But I'm having some trouble with linuxcnc, I want you to help me.

I have a mesa 7i96s card. I control the spindle with step/dir and I want to use it both for turning and as an a-axis. I'm homing the a-axis, no problem.
I want to do this; I want the a-axis to find the ahome switch again using g28 in the program. The a-axis should rotate until it finds the switch. How do I reset the joint.3.homing pin with g-code? How can it homing again with g-code?

You would probably need to post your hal/ini files for anyone to determine the cause.
 

Sometimes two axes with MPG are switched on. Where should I look for the error?

AMT is still enabled

I think you need to enter MEBx to disable AMT

I would do a web search in the steps needed for this
on your particular CPU.

Also, posting your hal/ini files might help, getting a watchdog bite without a
"error finishing read"  is a bit odd

 

looks hot with a fresh coat of paint. Need to put some sort of solution in the water to keep it from rusting. i blew the old hypertherm out yesterday and just about got it all rigged up today may try to put power to it and see what happens. The cable chain adds ALOT of resistance to the machine should I be concerned with this? 


 

Getting the 0-10 output from the VFD into the 7i67 and LinuxCNC for the feedback would be a win. But would that go to one of the ports labeled as mpg1a/b 2a/b? (that's where i currently have my homing switches)

The 7I76 has 4 analog inputs (on field inputs 1,2,3,4), but typically its better to use encoder feedback
 

Did you mean this?
 
 

Now that I've tightened up my estop game, I can no longer simply turn off my stepper drivers in order to run simulations on my mill software, since doing so makes everything else think there's a fault.  I knew this would happen, but I promised myself I'd figure out how to use a sim instead.

What's the easiest way to copy a mill configuration, and turn the hardware-aware parts into a simulation?  I'd like to preserve as much of my UI (including pyvcp panel) as possible, even if much is non-functional.

(If that's hard, I'll settle for a recommendation on the most functional x/y/z sim to use, instead.)

in the BIOS, at a minimum, Disable AMT

 

So stuff seems to work.
Next up is probing.
I have a tool setter on the bed..and an edge finder for in the spindle.
The 2 macro's work (should have copied them so I could include them here).
I mount the probe and touch it off on the tool setter. Then I manually direct the spindle to the workpiece corner and do the probe.
The workpiece corner is about x450 y400 z-23
When I then do a
G54
G1 x20 y20 f150
The spindle moves towards the machine home zero. Instead of 20x20 relative to the workpiece corner.
In the tool table G54 has coords like X25.645 Y62.956 and Z at 3.457
How?

Hello Tommylight, 

here my BIOS Settings.
Any Idea what I should change?
 
 

I will download the iso and try
What is the difference to the standard iso?

Thanks
