Is there any idiots guide to GUIs?

Category: General LinuxCNC Questions

Debian 13.7 was only released earlier this month (on 12 September) so its quite possible at this early stage that something Debian did with versions that broke LinuxCNC. Instead of complaining to all and sundry, why not raise an issue on GitHub so the devs can look at it? They are probably not aware of the issue.

Z axis torch initially going up instead of down when clicking cycle start

Category: Plasmac

Ok so I got it fixed by finding some settings in my notes that worked. So basically I entered these settings to the Z axis.
 
Now the torch still goes up initially but it doesnt hit the limit and it cuts just fine.
 
Im not entirely sure how these changes fixed my machine.

NativeCAM Problems with Program Start after transfer to Control

Category: NativeCAM

Hello everyone,
I have installed the latest version of NativeCAM under the Gmoccapy user interface of LinuxCNC. So far it works, but every time after transferring a new program to the control, I always have to press the start button twice to launch the program.
The first time I press it, the milling spindle starts briefly, stops immediately, and then I receive several error messages:
  • invalid parameters in linear command
  • linear move on line 38 would exceed positive limit of axis/joint 2
  • linear move on line 38 would exceed positive limit of axis/joint Z
After that, I can restart the program again and again without any problems, until I transfer a new program (or the same one again) to the control.
What could be the cause of this error?
Thank you very much in advance for your help.

Connect external potmeters to rapid- and feedrate override sliders in QTDragon

Category: Qtvcp

Thanks again for setting me on the right track again, this is really appreciated. In my case I only included 2 potmeters on the console: one for rapid traverse override and one for feedrate override. I copied this from a DMU 50 console which we have at work...

Using HALshow and setting halui.rapid-override.direct-value to True (1) and then setting halui.rapid-override.counts to a manual value (I discovered that a value of 10 corresponds to 100%) works well together with QTDragon_HD. With that I mean that it will probably provide me with the functionality I need. I already wrote some HAL lines using the lincurve component to ensure that the output of the potmeters correspond to the tickmarks (it is not a linear scale...).  By setting up the right net statements I should be able to connect these and have QTDragon follow this setting on the display. Same for halui.feed-override.direct-value and ..counts.

@cmorley: Luckily I didn't include a jog override pot on my console, as I now understand from you that this would not work in a similar manner. I did already buy a pendant (XHC with cable type) and maybe I will run into issues once I try to get that connected. For now I first want to get the spindle and servo's running :-).

Thank you all for helping me further.

Sounds like numbpy is the wrong version.

More specifically, it looks like someone did some good work in the 2.9 branch (Qtdragon works with the new numpy 2.2.4), but didn't port it to the 2.10 branch...

As you said qtdragon being python doesn't compile anything.
It preprocess somethings into to bytecode.
Sounds like numbpy is the wrong version.
But now we can investigate, thank you.

So you didn't home the machine while trying to decide if the screen is 'useful' ?
and there was extra information in the list that you didn't like?
Oh and the colors -colors were bad.
And that was worth going on the forum and ranting about how bad the software is?
Sounds like you didn't give it much of a chance.

Shake my head.

I'll try to replicate the numbpy problem.

Compiling problems aren't usually QtDragons fault - you didn't  mention what system you are compiling in so no one could help or evaluate the problem.

I'm sorry Qtdragon didn't suit you out of the box, but there is quite alot you could change.
For instance based on your pic, you could turn on the machine and home it, then the colors change from disabled to enabled and look like this:

 

 

First, about compilation issues.
My system is Debian 13.7 and the LinuxCNC sources are from the Git repository, main branch, i.e. version 2.10.
There is some misunderstanding here, because when LinuxCNC is compiled, the Python scripts are not compiled, but only copied to the right place. This means that if the scripts author screws up, it's his fault, because compilation itself doesn't change anything.
So we have the following flower:
 
This is what happens after compiling LinuxCNC yourself.
However, there are two live images that I ran.
1. linuxcnc_2.9.10-amd64.hybrid.iso
2. linuxcnc_2.10.pre1-amd64.hybrid.iso
Qtdragon starts in both, but neither suits my system.
In linuxcnc_2.9.10-amd64.hybrid.iso there is numpy 2.2.4 but LinuxCNC is 2.9.
In linuxcnc_2.10.pre1-amd64.hybrid.iso there is LinuxCNC 2.10, but Debian 12 with numpy 1.24.2.
Someone's sources have obviously gone wrong...

As for these "gray on grey" numbers, I wrote that I ran Qtdragon for the first time in my life and just took a look. I opened the tab called "offsets", so I thought there were offsets there and it didn't occur to me that it would only work after homing, because offsets have nothing to do with homing the machine.
Well, now I noticed that someone stuffed a machine position into the offsets, for unknown reason, because they can be seen much more conveniently in the window below. I started to wonder what else the authors of Qtdragon would surprise me with, but I think I'm less and less curious about it.

Hello,
I’ve installed the DebianNetInstall.iso without a desktop environment, and then installed the real-time kernel, LCNC, Openbox, and a very simple file manager via the terminal. It seems to be working—very low jitter.

Retrofitting a 3-axis VMC with DC servos - guidance needed

Category: Driver Boards

From what I've measured, the issue seems to be on the encoder side.

I initially thought that analog ground and power/system ground were connected. The original cables are currently in use. According to the diagrams, the analog signal for the axis is connected to the machine's frame/ground.

Is it better to isolate the analog ground from the system ground? Under what conditions is it strictly necessary to tie both grounds together?

Looking urgently for a german / european Linux CNC consulting help.

Category: General LinuxCNC Questions

Dear Everyone, 

we did some time ago a linux CNC retrofit with mesa board. We got mostly everything to work, probing and multi height sensor does not and I have to say i would love to get into it and spend the time to get QT dragon to work properly, but the time is becoming crucial and the machine should be running. 
Hence I would like to ask, if there is someone who would be able to either come hands-hand for a 1-2 days and or work remotely with us. Paid of course. 

It is a 1200x1000mm 3axis cnc german spindle, chineese base, completely new electronics from us with Mesa ethernet board. 
I have an xyz probe and tool length measure. 

I would prefer a european source just for the time difference but since it is rather urgent and we seem to be quite stuck in the process, i would take any help we can get. 

Any tip is more then welcome. 
(i will search the forum for the Tods and Davids of course, i saw many many cnc advice online and will try to reach out as well. )
