This would be the handler.py for the popup, the ui is currently a blank QDialog Window from QTDesigner nothing on it, i would add that after i got the window working like i want it to work. The problem is that it is something self created and nothing really proofed. I ocouldnt find a post here in the forum and the LinuxWiki side about Qtvcp and QtDragon isnt helping much ,too. Ive really no idea if im even on the right way.

Hello everyone, I’m asking for your help to understand how I can automatically square my gantry, which is equipped with two motors for the Y and Z axes. The motors have multi-turn absolute encoders, so I don’t have sensors for homing. For me, it would be enough if both motors had the same value. Currently, I perform this operation manually in jog mode when starting LinuxCNC. I’m attaching both the .ini and .hal files. Thanks for your help.

can you post the ui file that defines your popup dialog?

The best way may depend a lot on what your machine is, what tooling you have available, and even how many of these parts you need to make.

If the part is a low volume part, positioning the part at the correct angle to the head in a fixture and mill the angle with an end mill on a manual machine. Or if you have a multi axis machine (4th or 5th axis) that can mill at the required angle. Another option would be to use a profile mill with the proper angle built into the tool. And of course using a ball end mill to approximate the profile with many passes is always an option.

you already have a thread asking the exact same topic:
forum.linuxcnc.org/38-general-linuxcnc-q...7775-code-g71#338257
Please continue there.


You have been given a working example gcode. Have you tested that?

Also, you are not providing much information to go on.
Usually a good idea to provide a minimal example of gcode with an explanation of what exactly is not working how you expect it to.

Thank you very much for the quick turnaround and for providing the custom bitfile.
I have successfully flashed it and will begin testing shortly.

I really appreciate your help and support.

Hey there,
im trying to get a popup done by myself, if i press a GUI Button i would like to get a Popup where i could have some checkboxes and monitoring some pressure inputs. I tryed to find something about the topic here but i didnt really found anything, is there a topic that already deals with this topic? Or is there someone who tryed something like that? Ive created my own .ui File, and tryed to implement it once by the main handler what just leaded a lot of crashes, then i tryed a own handler for the ui what in my opinion is the cleaner way, but sadly same result. i didnt touch any old code in the handler but it still crashes on a buttons i never touched or created myself.

Thx for any help

I don't know if this is needed or not (my M6 macro does it for me) but are you calling G43 after each tool change where you don't touch off, to load that tool's offsets?

Thank you. After two days i know how to make to motor run. But now the following error of two motor are the same, but still too big sometime with rapid move can up to 1.6mm I think have to tune the motor, but i still dont know how to do it.
So in next step i will try how to input servo load  and digital input to add home switch.

After finish the these step i will update more

Need help using G71,
 lenux cnc will not recognize U or W commands. 

Thank you

I just put an intel i226-V PCIe card in on igc driver.  It seems silly to get a 2.5G card to run at 100M but it is cheap and works so far with no problems.  You can check the driver list here:  IgH EtherCAT Master: Device Drivers  for supported drivers.

I am also curious if TSN has any effect, I have not seen how this integrates into ethercat or linuxcnc.

 

 

Is this also the case with the 5.4.279 kernel? 

Can you try commenting out the "addf pwmgen...." in the HAL file? 
(this will prevent the spindle PWM working, but will give some indication where the problem might be) 

I commented out a # in this line:
#addf pwm gen.make-pulsos base-thread
The spindle doesn't spin, but at least the inverter turns on now.

The error consists of: creating a machine in linuxcnc, I follow these options that allow me to use automatic spindle control. But after completing the configuration and opening linuxcnc, the PC shuts down, and I need to reset the PC.

Yes, it happens with kernel 5.4.279.
And perhaps it's a detail that some have overlooked with this "return to login screen and black screen" freezing factor. But without a doubt, on this same PC that I tried several times with Debian 12 RTAI without success, it finally ran the Linux RTAI that you modified. The PWM and spindle issue is another task that will eventually lead to a solution. In the meantime, I'll keep testing and posting the results if you discover any clues.

Turns out it was a stepper driver.
Apparently I mixed them up while swapping back and forth for testing.
I´m sorry, but thank you for the help!

 
"Another one has 4.9V to 0.04V and doesn´t work."

Sounds like a wiring issue as it seems there is  no load on that 7I96S output.

Are the outputs wired differentially? (STEP+and STEP- both used)
