I don't have a Mesa CT2 file created yet - I'm still hoping to find a "pure" way to create it via pnconfig in one step - without inserting lines.
I have a small lathe that I would like to use in 3 configurations - as a lathe, as a milling machine (I have a milling attachment for the lathe) and as a rotary table, when the additional spindle (which will be classically driven via an inverter) will be on the support.
my machine:

There is a tutorial to get a working config for the EK1100. Maybe that is something to start with:
github.com/pklopping/linuxcnc-ethercat-b...asic_digital_outputs

For the drives there is this example config:
github.com/dbraun1981/hal-cia402

Im in the same boat. I have stepperonline A6 servos showing up as slave devices. now have no clue what to do next. 

Im thinking I can send-cut-send a panel, with switches as desired, and use a keyboard USB "brain" to read them. then basically map them however needed at that point. that's the easier part for me. Learning the computer/software GUI stuff is gonna be a learning curve.

The drives are 33 years old and the machine was in service till this year on a nearly daily basis. And again. The drives are known for having problems with the tantals. I dont want to have problems later on which I could had easily avoided.

Schema here 
 

Anyone?

One way:

in the main hal file add:


net spindle-vel-rpm hm2_[MESA](BOARD).0.encoder.00.velocity-rpm


in the gui hal file delete:

net spindle.0.revs  => qtpyvcp.spindle-encoder-rpm.in

and add:

net spindle-vel-rpm  => qtpyvcp.spindle-encoder-rpm.in

Hi guys, can't get spindle RPM to display, i have noticed a few different examples in the postgui.hal but non seem to work, i just get a -0 in my rpm display, I will attach my postgui.hal and my main.hal and a screenshot of halshow. Hopefully it's something very basic.thanks in advance

     

Yes, looks like an encoder issue of some kind (especially the sudden drop to 0 velocity)

I would try lowering  the emulated encoder output scale, as
maybe the drive has an issue with quadrature generation at high
speeds and high  resolutions.

Its probably easier to add the step/dir spindle to a MesaCT created configuration.

Can you post your MesaCT created hal/ini/io files?

No more than handful of lines need to be added.
 

I know - it is very unusual as a linuxcnc noob to start with an ethercat setup especially when you are en ethercat noob as well...
but I was so fascinated that I just wanted to give it a try.
Now I am at the point where Linuxcnc is installed, my ethercat is running and I get this terminal output:
0  0:0  OP      +  EK1100 EtherCAT-Koppler (2A E-Bus)
1  0:1  OP      +  EL1088 8Ch. Dig. Input 24V, 3ms, negative
2  0:2  OP      +  EL1008 8K. Dig. Eingang 24V, 3ms
3  0:3  OP      +  EL2008 8K. Dig. Ausgang 24V, 0.5A
4  0:4  OP      +  EL1008 8K. Dig. Eingang 24V, 3ms
5  0:5  OP      +  EL2008 8K. Dig. Ausgang 24V, 0.5A
6  0:6  SAFEOP  E  AS715N_sAxis_V0.10
7  0:7  SAFEOP  E  AS715N_sAxis_V0.10
8  0:8  SAFEOP  E  AS715N_sAxis_V0.10

As servos I use 3x Stepperonline OMC a6 400W

Now I tried to figure out how to build a working xml and a corresponding hal file.
After several hours of reading try`ll and error my last hope is that somebody of you would be so kind to share its xml and hal (best with running a6 servos) file so that I have a starting point for my setup.

Any help or hint is highly appreciated!

One: as you said... puff
Two: smd caps is faster to replace. I have to change nearly 30 caps each driver. So 90 in total.

When clipping the old one and soldering the smd on the other side directly on/over the drilled holes its a damn fast way. Cleaning the holes, soldering tantals in, clipping the wires taked more time...

So mainly cause I am lazy. And tantals costs (in comparable quality at my normal suppliers) round about 15 to 20 euros more than smd ceramics.

You will want to qualify the analog jog with another button press. Both selected speed and analog stick need to be active for jog to occur.
Without this the machine will jog if the analog stick gets stuck at non-zero, which will happen when chips or dust get into the stick.  When this happens I take the joypad apart and blow it out with air. After 4-5 years of using joypads on three machines, I should probably ebay a spare.

yes that's it. Not sure why the .jpg nor .zip download doesn't work anymore.

If you add these two of these files to your postgui list, you don't need to make any changes to your main configuration .hal. The first file is joystick_jog_speed.hal. Next add _xz or _xyz for a xz lathe or xyz mill configuration.  You will also want _extras.hal as it lets you use btn-base and btn-top to go between manual and auto mode. Keeping all your joypad .hal in separate files helps keep track of changes and allows you to simply remove the joypad from a configuration is it's not available. These files have been used on many 2.9.x machines. (Small changes to several names with 2.8.x machines.)
