Switch relay in a defined x position

Category: Advanced Configuration

Hello everyone,

I would like to revisit this topic.
The component has been working very well and reliably for three years now.
Unfortunately, I have already broken the spindle support twice, but this was not due to the component itself, but rather to the compressed air in our workshop.
I would therefore like to install a position switch to check the position of the cylinder and ensure that it is actually retracted.
To do this, the component would need to be expanded with an additional pin and a query.
Now my question to you, or rather to Rod, is whether you could help me with this again?
This is the current Comp file:
component spinport "LinuxCNC HAL component that switches the spindle support";

description
"""
Component to trigger the spindle support

\\fBEXAMPLE:\\fR
.br

 
.br
loadrt spinport names=spport
.br
addf spport servo-thread
.br
net position axis.y.pos-cmd    => spport.position
.br
setp spport.on 900
.br
setp spport.off 1600
.br
net spport-trigger spport.trigger

""";


author "Rod Webster";

pin   in  float position    "Motion signal for Axis position";
pin   out bit trigger       "True if spinport segment should be triggered";
param rw  float on     "Absolute axis coordinate from which the support is retracted"; 
param rw  float off      "Absolute axis coordinate from which the support is extended";

Servo Spindle with velocity AND position mode for Toolchanger?

Category: Advanced Configuration

I keep meaning to write a documentation section about toolchangers, as they are a frequent cause of problems, but despite being the author of the carousel component, I don't actually have a toolchanger on my own machines.

Servo Spindle with velocity AND position mode for Toolchanger?

Category: Advanced Configuration

This would be a complete bodge, but what happens if you just double the pocket number before sending it to the carousel component?

Can you describe exactly what feedback pins you have from the toolchanger hardware, and how they behave during a change?

Surfacemap Z compensation with Probe Basic

Category: QtPyVCP

I've looked again at the probe basic sim options...

Firstly, when I launch linuxcnc and the configuration selector comes up, under Sample Configurations > sim there are entries for other guis but none for probe basic. (It seems like that is where I should find the sim).

Instead under My Configurations there is:
probe_basic
> pb_required_ini_settings
> probe_basic

I think the last one is what you are referring to as the sim.

(I also have the probe_basic config I've been trying to get working but saved under a different name).

When I run that thing we are calling the "sim" it shows me the probe_basic screen and gives no errors. On the main page I can move the virtual spindle with the jog buttons.

However, I can't load a tool onto the spindle and all of the probe operations are greyed out.

Edit: I deleted the pb_required_ini_settings file and that option disapeared from the configuration selector. I also managed to load the probe into the spindle in the sim (which stopped the the probe operations being greyed out). However probe operations failed due to not hiting anything before the maximum distance. (which I guess is expected because it is a sim)?

So, I think the sim is working. Am I supposed to test more than this? If so, what?

Gmoccapi Vollbild Modus + Lathe Macros macht Probleme

Category: Deutsch

I would be curious to see if the problem also exists with the v2 macros, but I don't know if they even work at all on 2.9 (it will depend on the Linux version more than the LinuxCNC version I think)

This feels like a problem with the embedded tab handling in the GUI rather than directly with the lathe macros, though it is entirely possible that, through ignorance, I am doing something wrong in the handler code.
