The better way is to use estop_latch. There is a tutorial here
forum.linuxcnc.org/47-hal-examples/25861-external-e-stop
it is possible to daisy chain multiple estop_latch components together but its not documented anywhere
I found drawing a diagram of the connections helps to work it out.
Here is  video which may be useful

 

holy shit I am not sure why they made this so hard. they are using a different font class
for changing the font size in the file menu -

for posteriority heres how I got there. fbox takes the files and makes them into an Iconlist, which then uses the font family TkIconFont to configure this megawidget "Iconlist"

I thought it was odd that some of the widgets configured to our textsize and font but some did not. Its the same case for the entry widget that loads the file name. The colours dont change for most widgets unless you change the colour after you open, and even then only some widgets configure. The options in the listbox configure colour but none of the other text changes colour.

nawaf are you using regularmac800? that will make this easier. you can just add those 2 lines, or get the update from the github.

unfortunately this doesnt make it a better file browser. there are some alternative ones i want to try out when i figure out how

Hi Friends, 

Not sure this is the right place for this but here we are. I just about finishing transitioning my Queenbee Pro ( Link ) from mach 3 to LCNC with the help of a mesa 7i96s card. I have been following  this guide  as much as made sense and was able to get through the setup. My intent was to get though the setup then tune everything in once i am sure it all works. I am building a tangential cutter with a servo motor as the cutting head so i went with an XYZA setup and didn't include a spindle.

Now that i am through the setup i use the new desktop shortcut to open and start to try and run the machine and i click the estop in the top right (gmocappy) and get the following message, "External ESTOP is set, could not change state!". 

I have two e stops but one is configured in the pncconf as a custom input (was planning on putting them in series eventually or making the custom input an estop function if i can figure that out) and they're both NC. It doesn't go through any motors/drivers its simply ran from +24V Power Supply --> External Estop-->  Mesa Pin. Is this correct??

I am happy to provide any files or logs that can assist. 

 

I just received a XP200-30pl servo drive and I am now looking for a manual in English. The documentation sent was a one page sheet all in Chinese I noticed in this thread that there is a I/O drawing in English. If someone has a English manual for the XP200 please send let me know.

Thanks

I have not found any formal documentation on the encoders or any note in the machine’s schematics, so I don’t know.

You did say in a previous response that you thought my encoders are 1M units per revolution, in response to a post where I provided the model number.

Tomorrow I will do more testing - I will try to verify one complete rotation and see how the counts check out.

What is the counts per turn value for the encoder?

The machine does not have internet access (I blacklisted e1000e on Debian).

Ubuntu (the PC is dual-boot Ubuntu 24.04 LTS (for everyday stuff) and Debian LinuxCNC) has internet access, but it is annoying to copy the file.

Back from holidays, finally got to dig a little deeper with the oscilloscope. I managed to figure out the polarity of the connections and alas, I am now receiving the response from the encoder!

Some values are showing up on my HAL Show and now I need to figure out if everything is working correctly and whether or not I need to create a custom setup string.

After a slight turn (a few degrees) of the motor shaft in the reverse direction my HAL show reads:

 

Suggestions for next steps are encouraged.

I have the same drive, did you solve this problem? I have an xml from lichuan that appears to be designed for use with Beckhoff software, I don't know if it will work for Linuxcnc

In both cases, if the encoder is scaled correctly, the encoder velocity will read
machine units per second for linear axis and revolutions per second for spindles.
(there's also revolutions/distance per minute encoder velocity pin)

So if you can command a maximum speed (10V on an analog system)
you can measure the velocity/rpm with the encoder feedback.

For linear axis you will have disconnect the motor from the ballscrew to do this test
also the maximum actual speed will be 10-20% less than the speed at 10V
because the PID loop needs some overhead.

If the machine uses mm units, 200m = 0.2 mm/division
and a velocity of 1 means 1mm/s

In halscope what are the units ?
For example if set f-error to 200m/div what and i see 1 div how this translates to mm ?
Also in cmd-velocity if i set to 1/div how this translates to mm/sec ?

I have seen a post by @andypugh that showed an alternative method of pid tuning
know anyone the link of this post ?

How can i find rapid speeds of machine ?
Is there an automated script that measures displacement/time to calculate rapid speed ?
Also how can measure max rpm of spindle with encoder installed ?

None of the above are OK, this is how it is usually done, almost always
forum.linuxcnc.org/38-general-linuxcnc-q...moving-axis-s#309571
You can have it as you want/like, but that will cause issues with every CAM you might use
Here is also the homing stuff
linuxcnc.org/docs/html/config/ini-homing.html
And to reverse motion to any axis, use the StepConf wizard to edit the existing config (or make a new one, you can have many configurations for a single machine), on the pinout page there is a check for reversing the signal to the right of every pin.

If the mouse fails whenever the spindle is running, the problem is more
likely to be caused by EMI from the spindle drive rather than the relay.

I would try (as tommylight suggested) a ferrite bead = common mode
choke around the 3 (UVW) spindle motor wires and a line filter in the
VFD AC supply
