i agree that there should be a new modular system so that everyone can incorporate their own ideas.
But this already exists: forum.linuxcnc.org/18-computer/49142-lin...cp5?start=450#308969

I am very enthusiastic about its design!

Here in this thread I would still like to build a rather small DIN-Rail board, not only with a DIN mount, but in a real DIN-Rail housing.
So that it is space-saving and sufficient for a large part of normal desktop milling, perhaps also for a lathe (1x index encoder).

It's not possible to call a [HALUI] MDI_COMMAND from Gcode. If you need to modify M6 then you would need to use a remap instead:

X axis problems...
Hey guys had a strange occurrence when I went to home my machine, One of the x motors started spinning and then had issues).
I suspected it was loose wiring. I took the motors off and one of the motors was not operating properly (It started and then changed directions the first time) Then both motors would spin and I manually moved the gantry to the sensors and 1 motor homed and the other motor just kept spinning.
I checked the continuity of each cable to the plug and everything seemed to be correct.
I checked all of the plugs in the control box and pushed everything in incase there was a loose plug.
When I was putting everything back together I decided to switch the motors across (I have been having inaccuracies of the motor on axis x2 when the gantry moves 2meters it is 0.5mm shorter than x1. Then when it goes back it is 1mm past the starting position.)
When I go to home now, both motors are now moving in a positive direction trying to home (and the x axis is showing that it is moving in a negative direction). I would think the motors are both identical and this would not happen?
I then tried to change the step scale in the ini file and reverse the positive to - and the negative to positive. It started to go in the right direction for about half a second then it changed directions and was going in the positive direction again. And the x axis was showing that it was going in a negative direction.
Any ideas for fualt finding this one?

You can wire the 0-10V MESA output through a DPDT relay to the servo controller and wire the REV signal to energize the relay and change the polarity of the 0-10V to the servo controller to reverse the direction.-

I tried to install LCNC in two desktops from bootable pen-drive and got security policy violation error (refer attached photo). Pen-drive created by Rufus.

Both desktops are windows pre-installed. But the same pen-drive runs the live version ok on an other desktop which has LCNC preinstalled. This is same with LCNC 2.9.2 and 2.9.3.

This is a new issue to me.

Any idea what is going wrong?

Guten morgen,
Danke für den link aber ohne it Kenntnisse ist das kaum zu bewerkstelligen.

Bekommt man noch ein 2.8.xx version zum download? Mit der funktioniert alles wie es soll.

Warum wurde das dann geändert das es nicht mehr so einfach funktioniert?

Oder gibt es eine möglichkeit den funktionierenden recher auf den neuen zu clonen? Hardware ist identisch nur die seriennummer ist um 1500 höher?

Danke und schöne Grüße

Yes, I use it. I think it's a great project.

I bet the M0 in your toolchange NGC is being caught in the handler code.
I never considered an M0 in remap code.

Spindle inhibit works by setting the spindle speed to zero, but the spindle is still on.
If your spindle won't honour 0 spindle speed then that is probably why it doesn't stop.
Maybe linuxcnc should turn the spindle off rather then set the speed 0 when spindle-inhibit is true. (The spindle on/off behavior has changed since inhibit was added. setting speed to zero used to turn the spindle off. )

Hi! I'm using linuxcnc with 4k OLED screen
This is very first alpha version.
You can test it if you like.
You can help me if you like.
I think it would be better to write GUI using C++ and OpenGL only.
But what scares me is that I will need to read 4000 lines of Axis code

Installation:
Unpack files for example to your Desktop (or to linuxcnc config folder)

Update your .ini file like this:

Instead of reinventing the wheel does anyone see an issue with using the standard db25 pinout that used by std parallel port break out boards ?

It makes for a quick entry point, easy conversion from a parallel port setup. I know the 17 pins is awkward, 99% of packages are multiples of 4 or 8.

For the output from the motherboard, FET bus switches and pullup resistors make for a simple 3.3v to 5v conversion (bus switches need a ~3.9 to ~4.2v supply), as used by one of the big hitters.

Those that want an easy entry can use the above mentioned std BoB, more advanced users can "roll their own".

Well I don't know why it says 2.9.2 and has the external-pause pin but lets put that aside for the moment.

The external-pause pin expects to be set high to pause and low to unpause.
Does your pin drive it like so or is it momentary high to pause and a momentary high to unpause?

AC servos usually have step/dir and CW/CCW and that is settable, in that case 7i96S should be used as step/dir, not 0-10V as it would also control the direction and the only change in hal is from stepgen type 0 to stepgen type 1 or 2, i forgot exactly.

Ok I pushed your fix to 2.9 and master.
There was a race condition in 2.9 that made it hard for me to see the problem on my computer. Most of the time the led was right, sometimes it looked out of sync.

Could you show an image of your custom screen? I'm happy that Qtvcp was flexible and documented enough to convince you to try something unique.

According to the manual When a halui MDI pin is set (pulsed) true, halui will send the MDI command defined in the INI. This will not always succeed depending on the current operating mode (e.g., while in AUTO halui can’t successfully send MDI commands).
