How is it possible that gmocappy jog buttons work after basic configuration? I Don't see any hal pin connections that make the jog buttons work?

P.s i know they somehow do work, but how and why do they work right out of the box after basic config? This is mostly to help my understanding of linuxcnc

Thanks. they don't have them. they are pretty impossible to find. I got these ones form amana tool, which I had thought would be reputable, but nope.

(for the record, anything worse then 0.0005" would be unacceptable here)

k, running my tool mag properties through yaskawas calculator to figure out inertia. you do quickly get out of range, but the 40mm 50w will be fine as long as i take some time accelerating. 1-2 seconds to get up to speed.

This doesnt need to be high performance, just for function testing.

That will make an encoder work as a MPG
if:

1. Jogging is enabled for joint 0

2. A non zero  joint jog scale is used

3. The machine is not homed
( AFAIK joint jog pins only work before homing
and axis jog pins only work after homing )

 

Will something like this make the gmocappy jog button move a stepper motor?

The jog buttons in the Gmoccpy GUI will work right out of the box once you have your basic configuration set up. 

 

sorry but in my mind package contain all .... and never think build process need library not necessary for running applications ..... so now I understand thanks

.... any how just discover pakage installer never install libnml or lnml .... and these is not undertand because in my knowelge lnml is necessary for a working Linuxcnc ...... so why is not present in package intallation of linuxcnc.deb of lmde6 ? perhaps is possible these? or simply it change name?

in lcnc 2.9.0 and 2.9.1 lnml was locate in /usr/include/linuxcnc ..... but not find these folder now .... why? Where are locate now? nautilus not find it ....

gmoccappy has its own methods. See Chapter 5 in its docs
linuxcnc.org/docs/stable/html/gui/gmoccapy.html

Thanks Chris!

I buy stuff from CTC tools ex Hong Kong who don't sell garbage. Last buy was ER20 collets. If they don't have a listing they might source it for you.
As far as shipping, I have had stuff arrive from them in the same time as stuff ordered from interstate in Australia

net    encoder-counts    <=   hm2_7i95.0.encoder.00.count
net    encoder-counts    =>   joint.0.jog-counts

Whilst mesa and ethercat might coexist as they NIC they use are defined for each environment, the question is why do that?
Ethercat can do everything a mesa card can do and then some.

Um, cause the machine is already running on the mesa and i just want to add one motor?

Not sure why you guys think a stepper would somehow be better than a servo? a nema 17 stepper has less torque than a 100w servo. I dont think inertia would be an issue on such a tiny magazine (only 120mm diam). it will only be moving about 100rpm with quite low acceleration.
 

Chris. did you push the changes to master?
if yes, then it's probably already in Seb's .debs
what is the line in the .pref file for the probe number??

how about something like   ps_probe_tool = xxx

Lots of work to get it done correctly. Look at the challenge many people face just trying to install the debs.

I have mentioned on the mailing list that because RTAI Debs exist, it would be quite easy to build a RTAI ISO  by forking our live installer.
Its not that much harder to get the installer build process to compile the debs

Most GUIs are written in python and use the Linuxcnc python API instead of connecting signals through hal pins:
linuxcnc.org/docs/devel/html/config/python-interface.html

Over time you will find that there usually are several possible ways to get something done in LinuxCNC.

thanks

I'm stuck now anyway. I ordered some "precision collet reducers" and one wound up with 0.0028" runout, and the other was 6.32mm instead of 6mm.

That's worse than even the most garbage $1 aliexpress collet reducer.

Sigh. now I need to figure out something else and likely wait weeks for it to arrive...
