....
For more outputs/stuff, you would have to go with what you did, and there are probably many ways of doing it, and you can use PyVCP panel to show info about it at all times:
linuxcnc.org/docs/html/gui/pyvcp.html
I use PyVCP panels a lot with Axis GUI, a lot, even for showing all Mesa IO and everything else, on industrial machines. :)
forum.linuxcnc.org/30-cnc-machines/31792...ofit?start=100#88523
See the right side, all is added as PyVCP panels.
 

I see there is a "sim.pyvcp.demo" "pyvcp.embed.tab" Which fits my bill quite closely. What I'd really would love is something added on the "F3" panel of axis:



I have no idea how to do that.
But also, maybe that is another thread in axis and at the wrong place here. Pls let know and I'd open a new thread there, leaving a hint here.

... following up on this, instead of working :-)
my parport pin usage:

 

So, it turns out langdons was right about some pins still being unused. I my case, pins 1, 8, 9 and 16 wait to be used. Hope I got the connection diagram of said 1N4148 diode and relays right, (I lack electronics knowledge). I am about to order this board:

www.conrad.com/en/p/tru-components-tc-99...-1-pc-s-2481804.html

I have a feeling, it has some sort of protection built in. The manual is not clear on this however. Anyway, some 1N4148 never seem to be unnecessary, so I order these:

www.conrad.com/en/p/tru-components-ultra...-150-ma-1581846.html

Are these OK?

"pwm/dir" (Out1) switches for spindle CCW

Category: Basic Configuration

Thanks Peter for coming by. I put your 3 lines in my .hal file but there is an error message:
...
Debug file information:
Note: Using POSIX realtime
./ttm_a.hal:298: parameter or pin 'hm2_6i25.0.gpio.007.is_output' not found
2077
Stopping realtime threads
...
Perhaps this is because  gpio.007 is "hm2/hm2_6i25.0:     IO Pin 007 (P3-17): PWMGen #0, pin Out1 (Dir or Down) (Output)"

Seems this gpio.007 is bound to "pwm/dir" (Out1) for signaling CCW, what I want to do is to use it as a signal to enable my VFD while CW rotation.
Because I'm low on outputs I want to use this gpio.007 with the relay.

Mesa 7i76eu gpio pins not working

Category: General LinuxCNC Questions

Had the same issue, need to wire the "orange block" so that your inputs and outputs have power. You should see a yellow light only with only Ethernet or 5v power..... and a red or green light with field power.

I think it's just the bottom one on that orange block that needs 24v and the top one needs ground but that's from memory.... please check the manual

Mesa 7i76eu gpio pins not working

Category: General LinuxCNC Questions

Hello,

I am using Mesa 7i76eu card to operate my 3 axis CNC mill. I connected the stepper motors and they work, I can move them with linuxCNC. Now I tried to connect PNP proximity sensors to use as homing switches, but they are not working. At first I was also getting an error when starting linuxCNC, but i noticed that is because W1 jumper fell out while wiring. I set the W1 jumper back to its original left position but the pins are still not working. I also noticed that i have a CR11 LED light turned on indicating field i/o fault. Does anyone have an idea what could be the problem.

Ended up reinstalling ethercat_dkms and ethercat_master, before that I got errors
of not being able to read PDO at 0x0000 or something. After reinstall that's gone.

Yes, I'm trying to float over the certificate thing without really understanding.
I did some reading on the subject and the lines you have in the sticky file should make secure boot and ethercat modules work together. I'll point to that next time.

Sorry, I don't do consulting.
But I'm often here on the forum and, as I do for everyone, I try to help.

Ethercat has its fair share of startup issues and that's what many people need help with. But after the devices are configured and working, it's just regular LinuxCNC, with HAL files, INI files and all that. Now you know something about ethercat, Tommy

Mir ist kein Weg bekannt um ausserhalb des Interpreters direkt auf gcode
Parameter zuzugreifen. Ein Auslesen von Paramterwerten ist somit (meines Wissens) nur von innerhalb des GCode Programms möglich.

1. Parameterwert in einen Analog Hal pin schreiben (zB M68 E0 Q#31)

2. Parameterwert mit Gcode logging in eine Datei schreiben
(logopen,myparams.txt)
(log,#31, #32, #33)
#31 = 1.23
(log,#31, #32, #33)
#32 = 4.23

scurve trajectory planner

Category: General LinuxCNC Questions

As far as I know, the Scurve Trajectory Planner plans the tool's trajectory using jerk, acceleration, and speed, which works very well, but doesn't take the constraints of the individual axes into account.
For example, the trajectory speed is constant in a 90° corner, while the axis speeds change without considering constraints.
This can be seen in my previous post.
I hope I explained the connections correctly.

M1xx: Controlling Relays (solenoids) from within axis MDI

Category: Advanced Configuration

I was looking for a way to control my vacuum table's vacuum pump from within axis.
To late, but:
Axis (and probably other GUI's) already have built in control for Mist and Flood so you could have just used those as that would also make it possible to use the M7/M8/M9 codes to control them directly, more info here
linuxcnc.org/docs/html/gcode/m-code.html#mcode:m7-m8-m9
For more outputs/stuff, you would have to go with what you did, and there are probably many ways of doing it, and you can use PyVCP panel to show info about it at all times:

See the right side, all is added as PyVCP panels.
P.S.
I was just searching for a retrofit i did to post the link here, bumped into my video from youtube posted by some russian company on rutube !!! And they wonder why the whole world hates them!
 

Tommy
you're never too late :-)
I'll check on the possibilities to use Mist and Flood and M7/M8/M9 codes. Looks handy to me. Thanks for pointing this out, was not aware of this stuff.
Counts for PyVCP panel too. I had a camalign tab in axis up. Still there, but defunct now, as the camera got brocken in a stupid action by myself. I'll check out the sims, I think I remember having seen Mist and Flood buttons just below the spindle control buttons.  That's really where I'd love to have them, eventually with a status led on the vacuum clamping, too. I would prefer a tab thought for stuff to set up before a running job, as that leaves more screen for real time animation. Not sure how to kinda move a panel into a tab. Tried that with the manual tool change panel and failed.

A parallel port has 12 output pins, that's a lot to work with.

But in case more than 12 outputs are needed, this method is great for non-latency-sensitive stuff.
 

I'll check on all available pins later today. Thx a ton for the hints. If I can do it over the parport, I 'd definetly be better off.

I could totally do that (rounding errors on this machine are so far below its backlash) but then I have to go through all the axes and recalculate steps per unit distance and bleah.

I tested the bitfile and it works for me on LinuxCNC 2.9.4 (all sserial ports on the 7I74 work)
(the 7I74 is on 6I25 P2 = HDR26)

Since it looks like you have and older installation, you may have been bitten by this bug:

github.com/LinuxCNC/linuxcnc/commit/24b9...d5ef156b4282f6191158

If so, you could update to something newer, or I could make firmware with no sserial on the 7I85
and on the 7I74 change the port to 0
