In /etc/default/grub:

GRUB_DISABLE_SUBMENU=true

You will need to modify the file with superuser permissions, but if you're new to Linux, using vim or nano might be too tedious. You can use something like:
or:and then launch the graphical editor as a superuser like so:or:I'm not on Debian right now, so if gksudo doesn't work, try gksu, and if that doesn't work, then resort to using `sudo` instead. Common practice is to never use `sudo` though for graphical applications.  After modifying /etc/default/grub (there should be a comment already in the file about GRUB_DISABLE_SUBMENU) run:Now count the number of menuentries starting from 0, then make that your `set default=` setting. Afterward, re-run:command again.

Index (Z pulse) Homing on Delta Servos 

I hope it's OK I add a bit more info to this thread specifically in regards to Delta servos. I bought some used ones quite cheaply. To me, it's a better deal than the no name ones as the Deltas have much better documentation and a proper tuning/setup software. (Actually, I am almost sure at least some of Automation Direct's servo series are rebranded Deltas, too.)

Earlier in the thread PCW mentioned a potential speed issue where the Mesa input may not be fast enough to read the index signal unless the index is somehow slowed down. But perhaps the following tidbit I found will help with this (it's from a different controller manufacturer describing  how to wire up index homing  ):

For proper operation it is necessary to rearrange DELTA drives default settings. Number of pulses of drives’ output encoder – should be shifted to a lower value to ensure adequate INDEX signal pulse length. P1-46 parameter set by default on 2500 pulses – set on 500 pulses per rev or less. This change has no influence on servo drives working precision because their internal procedures work on encoder full accuracy anyway.

PCW also suggested on email that I slow down the homing speed (home to regular limit/home switch can be faster, but then slow down the home to index/Z pulse after that). So, maybe a combination of lowering the pulse value for the encoder and slowing down the home speed a bit is the ticket.

Again, if you have B3s, A2s or perhaps A3s(?) you can try making the servo drives handle the homing routine. 

Yes, this firmware should work (though would need to be modified to add the fourth axis index input)

Hi Peter, 
I am the one who just ordered the 7i96s and 7i84u and talked about needing to read four index pulses. 
Is this the FW, I would need to make it work?

All best and thanks for the guiding on email, too,
David 
 

that is, I would try it with a configuration for 4 axes, it can probably be done as a lathe config with ``spindle synchronized motion'', but I have no experience on that topic.

hello, the question is interesting but the fact should be taken into account, the feedrate for the linear axis is understood by the configuration as mm/min, but for the rotary axis it is understood as deg/min. so depending on the transmission on the A axis the example shows that the same feed is for both x and A, mechanically the two speeds should be matched. of course it also depends on the thickness of the wire you are winding, so I would personally try to solve the problem by exporting gcode from a program that supports constant rotary operation, I know it can be done in ``deskproto'' and maybe I would try to define a stepover via the definition processing tools (for example, the endmill 1mm tool replaces a 1mm wire in practice, stepover 1mm as well), I would subsequently edit such a gcode to support cycle repetition. it is essential that the CAM program outputs adequate A and X feedrates to synchronize the movement.

hello, I managed to insert the firmware, I managed to ping my nvemV2 10.10.10.10, i also managed to do halcompile, i also transferred some of the basic configurations... unfortunately, starting linuxcnc via the command line, I get a blank, i.e. I can't start either one of the configurations. do you have any ideas? Thank you      

Thanks for your reply, tommylight.

Unfortunately, HOME_FINAL_VELOCITY is set appropriately.
The Homing parameter uses the value set in LinxCNC2.8.3.

Based on my experience adjusting the servo using AT-PID at that time, I think the PID module in 2.9.3 may have been replaced with AT-PID. I remember that AT-PID did not work properly even when connected to the Index-enable pin with JOINT and Encoder Index-enable.

Has anyone experienced this problem?

Thank you in advance.

Please find attached two files.
Just place both files in your config dir.

Than add the following lines to the [DISPLAY] section of your INI file.

EMBED_TAB_NAME = Spindle Button
EMBED_TAB_LOCATION = box_custom_4
EMBED_TAB_COMMAND = gladevcp -x {XID} -H spindle_button.hal spindle_button.glade


After starting your config you have spindle increase and decrease button.

Hi,
  I did just like you suggested.
I saved the two files to my config directory.
I copy and paste the 3 lines of code above into the [DISPLAY] section (very bottom of that section).

After starting up the system, I do not see where the buttons are at?

Was there something else I needed top do?

Do you maybe have some set speeds for one or the other?
On my rotary plasma machines i make separate configs for every diameter tube, so speeds and distances are set accordingly.

Wire stuff, set up, test.

Magic. I'll work on it tomorrow.
I'm in the UK so my brain is shutting down despite my protestations.

Not a gcode expert but I suspect a gcode issue because:

29 float OUT 0 motion.feed-inches-per-minute
29 float OUT 0 motion.feed-inches-per-second
29 bit IN FALSE motion.feed-inhibit
29 float OUT 0 motion.feed-mm-per-minute
29 float OUT 0 motion.feed-mm-per-second
29 float OUT 0 motion.feed-upm

The feed rate is set to 0

(or feed override in the GUI is set for 0)

Woo, thanks for help

have you considered maybe buying a inexpensive turret style tool changer of alibaba, they have some decent ones. what's your email ? i have a catalog full. you could even add a Y axis one to get really fancy , for example like this unit. This would really make the shuablin a much more useful and automated machine for not much money.
