Run GladeVCP from halrun

please post a complete halcmd file and the exact sequence of commands you execute before the error appears

- Michael

Hal file as attachment



I boot my system with desktop icon --> .sh file

so my startup command is linuxcnc /configs/Tron-CNC.ini


this error occures every time when I start LinuxCNC + my UI

When my UI comes up there is these 2 windows


Was this enough??

yes it was.

You want a HAL/Gladevcp only application, but nevertheless start it with Linuxcnc which starts a UI by itself, which is why you get several windows.

What you want is to start your application just with 'halcmd -f halfile'

Also, please see the example I gave here earlier how to wait for termination of the UI and shutdown hal. It is all outlined there, just follow that.

Thank you!!

I will test this when I get home, this might resolve on one additional problem too

Great. I will comment how it went

Hi, John,

I am a newby who is trying to make a simple .hal script to turn three motors, starting with just one motor. I found this thread wd5jwy posted back in 2012. He seemed to have it working. But I am still stuck.

I have a TB6560 3-axis controller connected to a parallel port. All three motors turned under Axis 2.7.4 after I configured using Stepconf wizard. But running halrun and clicking the Start button does turn the motors. There was also no error. However, I see the LED for that axis lit up and turned off with toggling the Start button.

Could you please tell me what I have wrong? The following is my .hal script for only one motor: x-axis. Thank you very much!

Thank you, Andy! I used this command:

>>halrun -I -f start.hal

And i saw the interactive prompt.

I got it working. The reason was the button link was not correct, and I didn't set the maxvel and maxaccel. They were all 0's!

I am very happy!

Thank you!
