It’s been 9months since I got near this project. But back at it again.
I’ve been working my way through pnc config and inputting all the axis info from the manuals and finally starting to wire up the mesa boards.

Big thanks to the feral engineer on YouTube with his Linux cnc bare bones series as this helped me understand what data needs to go where..

Linear scales are now connected up and reading in the correct directions.

I have finally decided on what way to wire each axis and name each axis. I’m sticking to the original Maho horizontal spindle configuration with the y axis moving the table up and down. This way in the future trouble shooting in the future will be less confusing as everything will match the original manuals.

Once if got as far as I can with pnc configuration I’ll make a second configuration for the vertical spindle which I will use the most.

Hallo tommy ,

vielen Dank, das hat funktioniert....

At least got it up and running. 
1. Had to replace "import imp" in  /usr/lib/python3/dist-packages/qtpyvcp/app/application.py 
with "import importlib.util"
and on line 159


This comes from the python3-qtpyvcp apt package.
Is it qtpyvcp to blame or trixie that doesn't provide the imp module?

2. Missing [PLASMAC]SLAT_TOP in ini file. Added
SLAT_TOP=0.0 in PLASMAC section.
I guess it could be given a default value as is done for so many variables when they are missing.

3. Locale problems. <string>:1: SyntaxWarning: invalid decimal literal
Started linuxcnc with


and it gives me a Monokrom screen.
 

Edit.
The LC_ALL=C wasn't needed.
But this one needs attention:

Yes I forgot to mention this. I have tested with the Plasamac postprocessor as well (the one I normally use with my QtPlasmac setup) with the same result. It works, if I deactivate the plasma_gcode_preprocessor in the Filter section of the INI but then I can obviously not use any of the advanced Monokrom features like hole detection.

Try this command and review results when completeThe max reading is usually the first entry as it connects so look at average and standard deviation.

how is the html code for grin?

That's quite an old video now. There are more reasons  in 2.10  to grin
In  2.10 there is a change to how Deb files are built by doing it the Debian way which installs all the dependencies for you. It is described in the building linuxcnc docs for 2.10. I do remember testing it prerelease and it was sooo simple,,, except for building the docs.

I have a problem with homing in the lcnc sim. First, i jog the axis xz and then try to home all axis, and it's works. But when i try to do that again, its only homing for the x axis, and z axis didn't go to the home coordinate. Already check the ini file and it's all same with x and z axis, what can i do to solve this.

And i also want to try to jog a-axis with external push button, is this hal configuration enough to do that

there should be a specific post processor for Plasmac shipped with Sheetcam (before QTplasmac) Try it and read the file as there are notes at the top.

@Tommy, line numbers in linuxcnc are optional and Sheetcam has settings to generate with and without.

If you use 2.10, there are some changes to make it easier by doing it the Debian way (to a Deb file). The Debian way installs all the required dependencies so check the 2.10 Docs. Otherwise there is a how to video on my MrRodW YouTube channel

Hi all

I have a dragon rise USB board (pendant) attached to one of my machines. When I first home the machine all of the buttons work as expected (IE I can jog the machine around)

After I press one of the macro buttons on the screen ( Switched Home or Work Zero) the USB pendant stops working.
I'm guessing that the macros are not exiting properly but I can find no errors.
I am running debian 3.10 with LinuxCNC 2.9.4

I'm hoping someone can give me some pointers on this.
Thanks
Alex
 

1. see below
2. yes
3. yes
About 1, it would be much better to have some pictures to be able to answer exactly, but in general, LinuxCNC is very flexible and quite easy to make it do pretty much everything within reason.
I am sure Todd has a machine with 4 of Z axis, just not sure if independent, but again sure it should be possible.
If you wander a bit through the "show your stuff" section of the forum, pretty quickly you can find all types of machines controlled by it, personally i have from small "scratcher" machines for pictures on granite/stone/glass to huge industrial machines (plasma, mills, lathes) and some welding robots and small dental 4 axis clear aligner cutter.
Plenty of pictures and videos there.

Thanks

Y370 laptop/tablet/pen/FHD 120Hz touchscreen
X1 Yoga gen1 laptop/tablet/FHD 120Hz touchscreen
Plain ol X240 seems OK also, had 2, still have one in active use

Notice the touchscreen and VSync frequency, those are very important as they are top of that line, meaning other versions might or might not be good latency vise.
The link i posted above has all the info and videos of them in use plasma cutting, so no interference issues with touchscreen.

Tommy,
could you kindly name a few of them?
I could test a T440p, T460p for example.

PS: these do NOT have touch screens, though

I don't think so, those appear to have analog sinusoidal outputs so
require an interpolator (that is, they are not standard quadrature encoders)
