hi, can this image use traight to gpio too, rp4b board and i made 3,3V to 5V output level converter board use traight gpio output to stepper motor drivers DM556,
and same i build optocouplr board all input opto to gpio can use safety all gpo, not used BOB card or other board, i made diy own in/out gpio to 5V convert board, hope image can use straight all step/dir, enable, signal out to gpio pin. its easy use level converter module can convert 3,3 rpi output to 5V input by stepper driver controller etc, DM556.
same i think can easy use optocoupler module all input gpio pins. 5-24V in to opto and then 3,3V safety to in rpi gpio.

Hello everyone,
First of all, thanks to PCW for pointing out that `sserial_port_0=20000000` in the driver config **should enable Mode 2**:

> In the driver config string will set the mode to 2 which will enable both the MPG encoder inputs and analog inputs.  
> Note that the encoder inputs are intended for MPG use and are fairly slow and do not support index.  
> You would normally use the 7I76EU high speed encoder input for the spindle (TB3 pins 7..15).

I have a **brand new Mesa 7I76EU** for my Maho MH400 mill and I want to use **Mode 2**:
- Inputs 16–19 for an **MPG handwheel (ABZ encoder)**  
- Inputs 00–03 as **analog inputs** for feedrate and spindle override

**What I have tried so far:**  
- In the `.ini` under `[HOSTMOT2]` I set:

[HOSTMOT2]
DRIVER=hm2_eth
BOARD=7i76eu
CONFIG="num_encoders=1 num_pwmgens=0 num_stepgens=5 sserial_port_0=20000000"

- In the HAL, the card is loaded like this:

loadrt hm2_eth board_ip="192.168.1.121" config="num_encoders=1 num_pwmgens=0 num_stepgens=5 sserial_port_0=20000000"
setp [HMOT](CARD0).watchdog.timeout_ns 5000000

- LinuxCNC detects the card correctly:

hm2_eth: discovered 7I76EU
hm2/hm2_7i76e.0: Smart Serial Firmware Version 43
Board hm2_7i76e.0.7i76.0.0 Hardware Mode 0 = standard
Board hm2_7i76e.0.7i76.0.0 Software Mode 0 = io_spin
Board hm2_7i76e.0.7i76.0.0 Software Mode 1 = io_ana_spin
Board hm2_7i76e.0.7i76.0.0 Software Mode 2 = io_enc_ana_spin_fv

**Problem / Open Questions:**  
- Despite this configuration, the card **does not automatically operate in Mode 2**.  
- I want to use the analog inputs and the MPG handwheel simultaneously, and monitor the spindle with an ABZ encoder, but the Mode 2 functionality does not seem active yet.  
- Is it possible that the mode must be **physically set via jumpers**, or is there another driver/firmware parameter I am missing?  
- Attempts to flash a Bitfile did **not work**.

Any advice on how to reliably activate Mode 2 without LinuxCNC entering a fault state would be greatly appreciated.

Thanks in advance!

You mean that led at the attached photo? I can´t find a probe section in QT Designer or do i need to be in Probe Basic Development modus instaed of stable?

And can you help me here -> 
However, I don't know how to link the light switch to the output of my Mesa 7i76e. I tried to implement "net light => hm2_7i76e.0.7i76e.0.0.output-02 <= qtpyvcp.light" in my postgui_hal. Unfortunately, that didn't work.

 

I all ,
I need help to finish my custom panel in Axis 2.9.8
I'm Under Debian 13 Trixie 
I get the buttons in the side of Axis   Jog Button for X Y Z (+ & - )
Jog Speed and Home Button 
No error messages when i start Axis nut jog button did not work (with Jog speed more than zero)
Home button his working (at least one !)

Can someone have a look in my files ? 
I have been looking on the web for ages now and look like my brain did not see the problem......

Thanks

Marco

One of the long term goals of the project, is to integrate it with AI I dont know if I will release this publicly or not as it will be to OP of a tool but If i do make it i will share it by pm to the members here. The idea is to be able to use ai to generate signs shapes parametric modeling, upload a photo and have it turn it into a silhouette, or design a cut file off of a text prompt, potentially a chat bot could also be implemented for diagnosis of the system. This same chat bot could be then implemented into a website and customers could very easily custom design there own signs etc, order them and we make them and ship them out.

I will continue working on it everyday, I know theres a way I can make this work with multiple programs but it really makes it hard for me to train someone on it. a built in 2d cad would be amazing too, even if its just super simple. My goal is to have it be the MS paint of cad lol.

Good start!

Materials, there are two ways (at least). One is to set all options in Sheetcam and that overrides the settings from the Materials tab.
Sheetcam is then the master of everything. That's what you have seen.

An other way is to set material index from sheetcam, it uses then the material index from the Materials tab.
Still, you need to select that when you sit with Sheetcam.
For that you need to go in the post processor code and change to false line 24
An other way, that I use, is to set material myself when I am at the machine.
Sheetcam only makes the cutting movements, not the material selection.
For that, insert comments in the printouts on line 171 in the post processorNote the initial ";" comment in the printout. Plus useTool=false.

Automatic nesting isn't needed, at least to start with.
Being able to read in several G-code objects and interactively
place them on a sheet would be golden.

I like your start and hope you continue.

What is monokrom? Im happy to use pre-made tools would save me alot of effort.

I ran sheet cam for a long time on my mach 3 plasma table. Maybe I am a little confused with qtplasmac its my first time using it. I just dont understand why you would have a materials tab and then end up setting all your speeds and feeds in sheet cam? Is this only for the conversational? Either way all in one would be much better. I am trying to keep it super simple so that I can teach people super easy how to run my machine. There also is no automatic nesting in sheet cam and I know this is not a easy task but, for a basic version should not be to crazy. This is what I have done so far, all internal to qtplasmac  

This is just an interpretation from reading similar issues here(forum), not empirical experience.

But the pattern you describe (random errors on startup, weird state after homing, reboot fixing it, and then everything staying stable) really looks like something in the startup / state synchronization / handshake is sometimes not lining up cleanly.

It doesn’t sound like a continuous motion control problem, more like: sometimes the system and the drives don’t start in exactly the same state (mode, position reference, command bits, etc.), and once that initial state is “clean”, everything behaves fine.

Things like edge-triggered vs level-triggered command bits, timing of enable/mode changes, or initial position/mode sync could easily lead to this kind of “works most of the time, but not always at startup” behavior.

So my guess would be to look closely at the startup sequence and state/mode/position synchronization, rather than at EtherCAT performance or servo tuning itself.

On the probe page in qt designer, there is a button where the probe to is and the output from linuxcnc goes to the led on the probe graphic, use that as a template

First i hear about btop ... strange as i used htop a lot a while back!
htop should be in the repos, old and new.

@tcbmetalworks, focus on the features you like to have.
I'm sure it will spark some interest when you show us.

Let me check... I see. Quoting
www.thomas-krenn.com/en/wiki/BTOP_-_Moni...nux_system_resources

"btop is the successor to bashtop and bpytop and provides a modern, resource-efficient interface for monitoring system resources such as CPU, memory, network, and processes."

and

"On Debian 12 and Ubuntu 22.04 or newer, btop is already included in the standard repository."

So I guess that explains why you don't have btop available.
