Duplomatic BSV N 160 Werkzeugwechsler / Turret

Hi Daniel,

Reading that you have successfully got your EmcoTurn 240 now running under LinuxCNC makes me very enthousiastic as I have my eyes a similar Emco collecting dust until I am ready to retrofit it too.
Do you have anything you have shared on the internet / this forum on your beautyful retrofit job?

Best regards,

Frans

I'm currently working on a Emcoturn 240 retrofit. But I'm having a bit of trouble to get the turret working. I used the duplo8.comp file. The inputs and outputs seem to be working correctly. I had the turret on position 4 and did a M6 T3 command, but it went to position 4. After that it kept rotating back and forth between positions 2 and 4. I found 2 changes in duplo8.comp (compared to duplo.comp). Duplo8.comp uses "while(lockingSwitch == 1)" to rotate the turret in the opposite direction, the original used "lockingSwitch == 0". That seems to be the correct way according to the manual. But when I use 0 instead of 1, the turret keeps spinning to a random position. Also at random times, not only during a toolchange command.

Does "parity_error = (pcalc ^= codparity );" actually have a use? Because the value of this bit seems to be random, constant flickering.

What could be the problem?

Hi All,

I've started working on the turret on my Emco lathe too.
It's a Sauter turret and there are many simularities with the Duplomatic turret described in this topic.
I connected all signal pins, like encoder and proximity detector, and if I manually turn the turret I can monitor the signals with Halshow in Linuxcnc UI.
Now I modified the duplo.comp file a little to match my signals.
From this topic I understood I should compile this sauter.comp file like this from within the config folder of my linuxcnc configuration:
sudo halcompile --compile --userspace sauter.comp 
It seems to compile without errors and as a result I do get a new executable file called sauter (also in the same config folder) and I call this file from my main hal file like this:
loadusr -W sauter

Unfortunately, when starting LinuxCNC, I do get this error which I don't understand and hope to get some help from the experts here at the forum:
 
Can anyone help and explain what I might be doing wrong?

 

please forgive my stupidity.
after compiling I should have done the next step too I now see:
sudo halcompile --install --userspace sauter.comp

This seems to get me a bit further into debugging.
I get a Pin 'sauter_us_toolchange' does not exist error, which I don't understand yet.
as I did initiate it in the main hal file:
net tool-change iocontrol.0.tool-change => sauter_us_toolchange

 
Anyone has a clue of what I might be doing wrong?


 

Thanks for waking me up
It's even worse, not only - and _ got mixed up, it should have been:
net tool-change iocontrol.0.tool-change => sauter.0.toolchange
net tool-changed iocontrol.0.tool-changed => sauter.0.toolchanged
net tool-number iocontrol.0.tool-prep-number => sauter.0.newtoolnumber

Now Linuxcnc at least starts ok again. Let's see if I can get the turret move...
