I have a 3d probe working with probe basic, I have bought a z probe and my question is can I use the 2 probes on the same input pin? Do I have to add a separate line in the hal file?

I have a rcPWM servo working with a GUI slider control.  I want two quick buttons, one OPEN, and one CLOSE.  How can I have a boolean button set a float value? 







 

ok so just ran the mesa wizard and copied and pasted, some spindle stuff. works, need it to be always positive but ya works

I don't know much, but a few days ago I also worked with modbus and mb2hal.  One really useful thing is to turn on debug mode and run linuxcc through the terminal.  You will see error messages.

ya 00.21 for auto mode and 00.31 for hand/manual

sudo apt tasksel
sudo tasksel

Select the desktop you want
The reason why we use xfce is because it is an Xorg distro and gnome by default ues Wayland which linuxcnc may not like
On the log on screen bottom right, there is a cog icon that lets you select running gnome on xorg

building from source is also well documented at Etherlab etherlab.org/en_GB/home

I would call it a Preempt-rt kernel bug since the r8169 driver is a FOSS kernel driver

done on network drivers (looking at the RT patches)
 

Agreed aboout the FOSS driver which was what I said in a round about way.
There are no Realtime network drivers because network communications is not considered to be real time, so its not really a RT issue. That's why the CPU affinity becomes important as it keeps the non RT NIC driver on the same isolated kernel as the servo thread.

You  need to write your own NIC driver. This has been done by the ethercat guys but I think they have mostly dropped them from their packages in favour of their generic driver which they acknowlwdge is not real time but is adequate for most Ethercat projects. If you compile Ethercat from source, you can use some Realtime NIC drivers but not sure how current they are.

@Lcvette, I have raised issues with both Debian and the RT kernel team and nobody really cares. If you want changes, you would need to do it yourself

Ok firemware loaded np, but cant get any analog out
linuxcnc.org/docs/html/examples/spindle.html, I Follow section 1. "0-10 Volt Spindle Speed" or section 2. "PWM Spindle Speed"

the second on seem more likely for the 7i33ta

Doesn't anyone know?

It look like J2 pins 1,2 are the differential analog input

So I would wire:

 7I77AOUT --> J2 pin 2   (non inverting differential input)
 7I77AGND --> J2 pin 1  (inverting differential input)

Or just supply the field power with say a 9-19VDC wall wart for testing

The servodrive was orginally connected to j2 pin1 and pin2, but since the the 7i77 has only single ended output for the drive I need to connect it to j1 pin2. Is that correct?

   

I know Tom and I feel you..... I have been working for large corporations long enough to know that everything that started as a passionate creation by totally dedicated engineers, will be transformed into a ruthless money making machine as soon as financially driven managers take over, whose interest is only the quarterly results. And when that happens, ethics are often thrown overboard and customers are fooled by sugar coated stories written by marketeers. Many good companies have been destroyed that way. But I also learned that complaining about it is not going to help and will only result in frustration and negative energy. Hence my suggestion to stop the bashing and try to make the best out of it. Sending out a reminder every now and then about how things suck doesn't hurt, but personally I don't let it prevail, as it does not help.

1. add this to the [RS274NGC] section of your ini file:
2. save your python script as eg 'M123' (possible numering is 100...199) to the 'mcodes' folder in your machine config directory and mark the file as executable

3.'M123' in Gcode should now execute the script.
