TB 6600 getting hot

Category: Driver Boards

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

Just for fun, here is the widget I described.

automatic initialization of the axis interface in full screen

Category: General LinuxCNC Questions

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:
nano ~/.axisrc

Add the following code to the .axisrc file:
root_window.attributes('-fullscreen', True)

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:
linuxcnc.org/docs/2.7/html/gui/axis.html#_axisrc

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

My system info Debian 10, Xcfe, LinuxCNC version 2.8.0

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 .

Hi, On the QtVCP website (linuxcnc.org/docs/html/gui/qtvcp.html) I saw a nice modified QtDragon screen.
See attachment.
Does anyone know if this is available somewhere to download?
Jus want to avoid to make it by myself...
Thanks

Carousel with analog servo drive

Category: Advanced Configuration

Does your PID control velocity or position? It would need to control velocity to work as intended with the carousel component.

The use the carousel.N.motor-vel output as the (velocity) PID command.

Now the component will derive the tool number from the index and tool pule inputs, and will simply drive the carousel motor at constant speed until the it sees the sensor for the selected too.

It _might_ work better in counts mode based on the encoder in the servo motor, but try it this way first.

Carousel with analog servo drive

Category: Advanced Configuration

Hello everyone, I am starting up an automatic tool change on my new milling machine and I have a problem connecting the carousel component. The carousel is rotated by a servo motor that I control with an analog signal. There is a gear transmission of unknown ratio between the motor and the carousel. There are two inductive sensors on the carousel for sensing the index and the tool position. Currently, the carousel rotates to the index after enabling. When entering the pocket number, the carousel rotates to the selected position, but only based on the number of encoder pulses, it ignores the tool position sensor. The signal for the motor goes through a PID loop, named pid.c. Should I unlink the encoder from the carousel component and connect the encoder only to the PID loop?

That was what I was wondering about trying first, yes.

I had thought that there was a way to pass extra args "through" dpkg but I didn't find it.

TB 6600 getting hot

Category: Driver Boards

Also, are these really a TB6600?
I bought one of these recently: www.amazon.co.uk/dp/B07SBZ9SM5
I took it apart and found there was lots of space inside (which suited me) but there is no sign of a TB6600 chip in there. I don't know what the actual power IC is, but it was small, square and surface mount.
It turns out that I am not the only one to wonder about this:
www.grbl.org/single-post/tb6600-fake-or-not-but-who-cares
The article above also points out that anything that supports x32 microstepping is _not_ a TB6600.

There is an advantage to this if you don't need more than 3A, there is lots of space inside, and I was able to build a little Hobbing / ELS controller directly into the stepper driver case (3D printing a new lid)
