Thank you

Dear onceloved
Normally, for cobots, origin position or zero position, they are saved some file in robot controller (txt file, or xml file). don't slave in object dictionaries of ethercat.

Thanks Phill. The buildbot situation seems to be dire and there are so many users that depend on them.

Hallo Tchefter,

danke für die genaue Auskunft.

Ich hab mich schon gewundert als ich eine Antwort geschrieben hate, das diese nicht angezeigt wurde. Vermutlich hatte ich auf"Report This" Button geklickt.

MfG.

I would recommend following PCW's advice so that both motors travel in the same direction.  It simplifies things.

When I was setting up I used axis as a test bed to get the wiring directions correct. Without setting the homing synch values to negatives I would manually move each motor a small amount with slow jog to ensure + and - moved the motors in the same direction.  Then went about setting up the homing values in each joint to be identical with a negative home sequence value to create the synch home requirement.

It's pretty skimpy on detail. Ask questions here and I'll try to help and maybe add docs for next time.

it's available in linuxcnc 2.9

My second question right now and a much lower priority than getting the spindle working is getting a new tool setter working.

I have found some videos and how tos but again it seems like several different ways of doing things.

Right now I have the manual toolchanger.
I would like to set it up to set a tool before running a program.
Preferably also to be able to change tools during a program. I could of course manually set it then have the next tool as a separate program but I assume it should be easy to do a manual toolchange and set tool mid program right?

I am also seriously eying an ATC spindle so I want it to be ready to do multi tool config with different tools saved in the tool table.

The one video I watched with setup details did the tool setting through the probe tab in AXIS. When I couldn't find it I did a search and found a thread that said it isn't in AXIS 2.9 or not yet or something. That thread said I can still access it in another UI but it doesn't seem like the best way to do everything I want anyway.

What's the best way to set this all up and is there a good guide, video, etc?

I am trying to get my Huanyang 2.2 kw VFD working properly. 
I set it up as  andypugh  describes here. 
forum.linuxcnc.org/27-driver-boards/3537...wiring-to-mesa-7i76e

I am still doing setup in pncconf and trying to do as much there as I can. I added the spindle setup and enabled spindle output in TB4. 
I am have been setting up for 10v speed control though I would love to use PWM if it was possible. 
Set voltage, max RPM, etc, in the spindle section of pncconf. 
I'm not sure whether I should be using "use +-voltage for direction" but it is not working properly either way. 
I was having issues with it only spinning one direction but messing with settings I do have it spinning both directions and with "invert motor direction" checked in the proper direction though it seems weird I should need to have that checked since it should all be set up to spin the proper direction. 

As it is set up right now it doesn't seem like the Mesa card is doing what it should be doing. 
If I start up linuxcnc and hit the spindle button it goes straight to 23k RPM and 9.5v on pin2-VI. 
If I slide the spindle override down it stays at 9.5v and RPM till it gets to about 30% and then drops to like 0.15v and spindle RPM drops to 3400 RPM per VFD display. Spindle speed is either 23k or 3.4k RPM. I haven't looked but maybe I set up a min speed in the VFD at some point. 

I also measured weird voltages on forward and reverse terminals but I don't remember all variables like whether I had +- voltage ticked. 
When I measured though I think with CW in Linuxcnc I measured 24v on forward terminal to ground and 24v between forward and reverse terminals. But when I put it in reverse (and the spindle did reverse) I showed no voltage between the ground I used before and no voltage between forward and reverse. 

I can't be bothered to set up and log into the forum on the machine right now but I can upload files or whatever if needed. I just have to imagine that either this is a simple fix or that there is a more comprehensive guide somewhere. 
The most frustrating thing with this is in a google search I have found like 6 different threads, how tos, etc, with wiring digrams that show 6 different ways and virtually no info on other settings to make the wiring configuration work properly. 


 

Thank you very much for your guidance.

I tested that the Flex GUI is very fast without QPlainTextEdit and plotter.


The problem is in QPlainTextEdit, can it be optimized not to load the full G-CODE file?

I had this machine running years ago on a cheap controller. Then bought this 7i76e and got some basic functionality then the machine went into storage for years. 
Now I'm trying to get it properly set up and add some features. 
I thought I would make a thread for this phase of the project instead of each individual question. 

 

Yes, I just tested it and it gets everything

That was fixed  on Nov 6 but it appears that buildbot2   has not built since Oct 24.The original buildbot is useless for master branch as the latest distro on it is buster.

A workaround for the time being would be to edit (as root) /usr/lib/python3/dist-packages/qtvcp/lib/qtplasmac/tooltips.py and change line 196 to:
