    Have a look here. With lspci -v i see no kernel drivers.
i beleive this could be the problem.
how to install the drivers? Since the parallel port supports different modes according to the manufacturer, im quite sure it is possible to acheive 9 inputs with proper knowledge

Nice job guys....

Try a Meanwelll MDR-10-5 (2 amp)
 
 

Hi Rod,

Thank you for the suggestion. I like to use the Meanwell MDR-10-5: au.rs-online.com/web/p/din-rail-power-supplies/7127402

It does not include the DIN Rail, which RS Online Supports say is: DIN Rail: au.rs-online.com/web/p/din-rails/6485722?gb=s

I would like to use the terminal blocks as per your spaceship video:





I sent them these two images stating that I would like to use them with the above power supply and DIN Rail.

But supports said not enough info, and suggested this: au.rs-online.com/web/c/connectors/termin...ds=Phoenix%20Contact

I also inquired about the earth one ( yellow and green ), but supports did not give a link for that.

Would you happen to have any suggestion on this terminal blocks, please?

I will use this power supply only for the Mesa 7i96s, so many of this terminal blocks I should need, please?

( For the stepper motors, I understand that I will have to have a separate power supply. )

Than you Rod.

I'm trying to add spindle enable and spindle out to my configuration (7i95T + 7i78), but heaving some difficulties to set it up in mesa CT as it is all greyed out under spindle tab and also under 7i78 outputs. Only under 7i95T outputs are 6 of them available.
I would like to use spindle outputs from 7i78.

Hi guys,
I've been lucky enough to find a used EL4031 used at an affordable price. I have set it up on LCNC and I can enable it. I can't keep going one with the setup because I'm a bit lost on what I should do next. I have found this example:



I'm not asking to do it for me, I want to learn so a practical example should be enough, I know the basics of C+ and did many arduino projects but I'm a bit lost on how to write code for LCNC.

Those pins need to be open collector pins according to the docs.
As you have followed the correct procedure to test if the pins are open collector and you saw no change that indicates that those pins are not open collector and can not be used as inputs.
As far as I know, I haven't looked at any data sheets, there is no way this can be changed.
I'm guessing this is the way the hardware is implemented on the chip itself, IE at the silicon die level.
The only way to find if this can be changed is to read the data sheets of the chip used on the board. Even if it may be possible it may require some mods at the PCB level.
Bear in mind that as I have not read the data sheets most of the above is speculation.

Hello all,

i have the following PCIe Parallel port card from StarTech , with Asix - AX99100 chipset which offers me 5 input and 12 output pins on default settings.
i tried to configure it on x mode with loadrt hal_parport cfg="d010 x" in my hal file. But i do not get the pins 1,14,16,17 to work as inputs. (they remain high and do not change states. I tried using a 470 ohm resistor between the pins and ground but the state does not change.

The manufacturer states that the port can be configured as SPP,ECP and EPP and is based on IEEE 1284 standard. 

Please help me to change the parallel port data transfer mode to the one which supports 9 inputs.

i have tried dmesg | grep parport in the terminal but there is no information relating to parport. and there is no way to change the mode of my parport from bios because its a pcie plug and play card.

there should be a way to change modes but i do not know where and how.

any help is much appreciated!

Hi,

I am not sure if this post is in the place or not. Please excuse me if it is not.

I am doing HAL basic tutorial: linuxcnc.org/docs/html/hal/tutorial.html#cha:hal-tutorial, under section 6.6. More Channels, Figure 13. Step Pulses shows HAL Oscilloscope with the Chan Off button, my version of the HAL Oscilloscope does not have one:



My LinuxCNC version is 2.9.3, which I built from source on November 6, 2024.

What can I do to fix this one, please?

Thank you.

Thank you dbtayl for the work you have put into FreeCAD. I stumble my way through coding so
I have a pretty good idea how much effort goes into making programs work. I liken it to one
beating their head against a wall until the wall finally cracks, Beat one's head against the wall
some more until they finally break through. But maybe that's just me. LOL

The direction is determined by the 'B' pin

If you are only measuring frequency you
can make firmware that has only 'A' inputs
 

I'm glad you mentioned the 'B' pin, because I just realized the 'B' pin is now floating on my isolated input, will fix that.

When you say "you can make firmware", what software tools would I need to do that?

It's been a while since I dabbled with VHDL, Verilog

Sorry for late comment.

1) the missing pan button is a mistake. It can be fixed
2) In master the axes selction buttons and DRO display can be clicked to set different things.
in 2.9 there is a REF button and a ZERO button. This can not easily be changed.
3) Probably could be done in 2.9

Thank you so much for your guidance.
What about enable pin? Joint.0.amp-enable-out?

Hello beauxnez,

on a fresh install from Linuxcnc from the ISO 2.9.4 it works with the two changes (ETH.h and puType::up;)
 
I think your problem is your system.
On which system do you work? Have you cleaned platformio/vscode?

 

Hi,

I like the idea also. So you want to go nearer to the points before doing a spline. 

I thought of splitting the resulting red points (limiting by gravity point an P) by half for example if the next angle is also in the same direction. Could be more sophisticated of course. Just a rough idea. This way we are not getting more inside in this situations.

Splitting in half between edgepoint and last point if next angle is the ame direction. And going one step back if the direction will change (not perfectly described of course).
