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:

Thank you for reminding me, i had forgotten about this

A perfect idea to cram in an ESP32 on every drive and have only power go to each drive/motor
I wonder what happens when the pilot arc strikes on a plasma...

Yes, it seems an entirely satisfactory stepper driver, but it is being mis-described.

Just for fun, here is the widget I described. 

 

I just wanted to add to Tommylight's answer - and for my own reference.

Here is how to configure the Axis GUI to start in fullscreen:

Create a new configuration file in your home directory (or edit the existing one, mine was absent) called .axisrc, open a terminal and run:
Add the following code to the .axisrc file:
Press 'ctl + x' then 'y' to save and exit nano in the terminal.

For these changes to take effect restart the Axis GUI (or restart the system).

The Axis GUI window will now occupy the entire screen, hiding the window borders and title bar. It will cover all OS navigation bars and menus.

Documentation on .axisrc can be found here:

If you want LinuxCNC to start the machine automatically in fullscreen upon starting the system you can: 

Enable automatic login:
linuxcnc.org/docs/stable/html/common/lin...tml#_automatic_login

Launch a LinuxCNC machine upon login:
linuxcnc.org/docs/stable/html/common/lin...l#_automatic_startup

NOTE: use alt + tab to navigate between programs in fullscreen mode

It's TB67S109 IIRC, it is a small QFN packaged chip

TB6600 is very finicky and dies easily, this S109 is much sturdier and can handle plenty of misuse .

Reply ist OK, das ist was ich nutze, immer.
