Aah of course, H is the once-per-rev signal. Somehow didn't occur to me, but now it makes sense, thank you!

They are connected directly to the ballscrews, the spindle encoder is connected via belt. They use "Heldt & Rossi SM 807 DC" servo drives for X and Z and a "Baumüller BKF 12/70/400" for the spindle. Controller is a "Sinumerik 3T".

Error in tool_offsetview.py

Category: Qtvcp

For now, m5 solves the problem in my tool measurement procedure. I do not use the built-in qtvcp procedures. Let someone smarter figure out how to solve the problem, I probably can't help.

Returning to the topic of the axis buttons function. Could you add the "go to zero" function?.
I only added the titles to the axis_tool_button.py file to the screenshot. I do not have the functions working yet.

They look like 'normal' differential encoder outputs.  A/A-, B/B-, and H/H-... with H being the once-per-rev index signal.

Should be a standard Mesa connection.

Are those encoders connected directly to the ballscrews, or to the motors?  What's driving the motors?

Weiler 160 CNC Retrofit

Category: Show Your Stuff

After years of using a very old (1930) and worn out lathe, I decided to get myself something new.
Found a Weiler 160 CNC in very good condition (400 spindle hours) that has been used lightly in a school. The buffer battery is dead and the screen does not turn on anymore, so a perfect project for a retrofit.
The documentation is one of the best I've ever seen, everything from bearing preloading up to motor change of the toolchanger is described. Tons of drawings from every part. The whole machine just screams german quality.
 
 

Only thing I'm not really sure about is the measuring system. It uses incremental encoders with 6 signal pins instead of glass scales. Does anyone know how I connect them to the mesa cards? Can I use the normal encoder inputs for that or do I need something else?

Quadrature decoding to produce pulse + direction

Category: HAL

Yes, basically LinuxCNCs motion component already does this with the MPG count.

Quadrature decoding to produce pulse + direction

Category: HAL

Hmmmm why?
LinuxCNC can use any encoder as MPG, so no need to convert anything, even on parallel port it works.

Quadrature decoding to produce pulse + direction

Category: HAL

I am building an MPG control for a Chinese 920 lathe I am converting to CNC. I want the controls to have the same intuitive feel as the original manual lathe, with the option of overriding to use full CNC, so will be fitting an MPG where the standard controls would be. I have the prototype setup working, using _encoder_ to decode the quadrature encoding (it is strange the the decoder component is called "encoder"). This produces a count, but I'd also like quadrature decoded to pulse + direction for further processing.

Is there any way of doing that with standard HAL components?

When I loaded latest debian, I thought linuxcnc will be included.

Can any one point me to the procedure where I can install linuxcnc to my existing debian 12.6

I already constructed a DIY machine running on linuxcnc using another pc, but I like the full version of debian 12.6.

Many thanks

Philip
