What I hope will be the last part of my adventure, is to add a spindle encoder for rigid tapping etc.Mission now achieved. 48 teeth on the lower side of the drive pully as well as an index tooth on the upper side, (complete with counterbalance weight).Have used ATS616LSG hall effects, with 10k biasing resistors which produce at the 7i77 encoder 05 inputs, good clean 5volt signals.I have yet to get properly to grips with the hal side of things, but at first sight, the hal scope doesn’t look right.

is this the <initcmd> tag?

I don't know that, but if you have static data you can set that using the SDO instead.

These servos have so many functions and parameters, that 10 is a really small limit.
Is there a way to split the pdoentry tags into multiple pdos?
Or change them during operation, e.g. have a different ethercat-conf.xml during homing vs. normal operation?

It is not uncommon for devices to have a limit on how much data they can exchange.
But do you need all of those PDOs? I guess not.
So just delete the ones you do not use from ethercat-conf.xml

Seems that there may actually be two printouts on the same line:which comes from motionwhich seems to come from the Axis GUI:
github.com/LinuxCNC/linuxcnc/blob/6f7753...s/tcl/axis.tcl#L1838
You are not giving us much else to go on. Are you getting getting following errors on joint 0 when using other Gcode or is it only with this particular program?

i have the attached ethercat-conf.xml (for stepperonline A6 servos).
Each time i add more than 10 pdoentry tags, i get the following error in /var/log/messages:

If i remove / comment out any one pdoentry, the error goes away.
master idx="0" has no error, idx="1" - idx="3" have the error.  
There seems to be a limit of max 10 entries?
How can i work around this?

 

Hey yall. Im a machinist by trade. I initially learned cnc on linuxcnc about 10y ago. Now I run "Real" cnc machines using fanuc and Haas. Initially I missed linuxcnc, but now when I go back and use my little linux mill, I am annoyed by the tool table and just the "PC" feel in general. The Fanuc soft keys are actually super nice and you can quickly go between work offsets, tool offsets ect. I can for example go to my absolute position page, do some mental math, type a number in the control, switch pages to my offsets, and input+ that number in seconds to quickly set offsets and stuff. No need for a mouse or anything silly like that. Hass is very similar but its even better with dedicated buttons to kick into the offsets or positions pages. Honestly the mouse is a major pain in a shop environment. The fanuc/Hass button based interaction is crazy fast for me compared to scrolling around on linuxcnc. suggestions? also itd be nice to get rid of the X Y tool offset and just have length/wear and diameter/wear. is there an "industrial GUI" im missing out on?

Can you post the terminal log?

( start Linuxcnc from the terminal and copy-paste the messages printed )

The previous error indicated an issue with a (probably USB) input device like a MPG

I would create  a configuration without the added input device to get past this error
for now

 

I have spent some more time trying to troubleshoot why I cant launch the software, I cant seem to figure out where I am going wrong, I have it real barebones. I am sure I am configuring something wrong I just cant get past the error message when I click the launch icon. it tells me to look at the inputs config or whatever but I am not even sure what that is. I think I am supposed to enter a serial port number somewhere for setting the mode that the 7i77 is in but I cant find that in the hal or ini file...

"[sic]" Love that!

Someone needs to work on their German (not you).

Still better than the plethora of typos in this license file: mipav.cit.nih.gov/license/CopyrightInfo.html

Pretty concerning that US government screwed up on basic English writing.

Thanks everyone, ill dig into the above suggestions. 

And yes, i should have been a little clearer, im not worried about the following error stuff, i was just happy to be seeing signs of life. 

Ok, think I have figured it out, most of it at least. Had to make a visual representation of the HAL finnstrom posted. See attachement. Also got it sort of working on my machine. Tanks so much!Some things I'll try to adopt

• Instead of controlling with coolant-mist, I would do it with a motion.digital-out pin controlled with M62 and M63
• Trying to get the w_offset from actual w0 in current coordinate system. My thought is to touch of both Z to the work piece, and set w0 in G54 (for example) at the desired height. Then, somehow in HAL, calculate the w0 offset from w joint zero. In the (unlikely) event that I need dust shoe for G55 etc, this should enable this to work.
• In conjunction with above, I think I need jogging to work (in qtdragon) to easy set w0 current coordinate system.

Thank you so much I am still having problems setting up the limit and home switches in the main hal , I used mesa CT here are my files, I noticed you used the code down below but i cant seem to replicat it without error

You are correct I have a paid license. I used to use the free version some time ago and I don't remember it having that limitation but I know they have made multiple license changes over time for the free version which is unfortunate. Glad to see you have made a solution to work around it.

I don't use axis but this post may be similar to what you are looking for:
