No that references Mesa Modbus and several userland modbus interfaces
that use kernel serial port/USB serial port drivers.

When you see errors like the missing dependency shown in the top line of your screen shot, those are what stop the installation from proceeding. While installing, if you encounter those, you can auto install them by running:

sudo apt --fix-broken install

which will gather all of the missing dependencies on your system and install them.

added location, had put on subject but added it to top of list now

Are you trying to install a dev work station or just a machine control? If a machine control, use the apt installation.

Hello,
this is my almost working postgui. This works is Input-04 is a switch. But i want to use a push button. What can i do?

#[Startknopf]
loadrt or2
addf or2.0 servo-thread

loadrt not #mit diesem Befehl wird ein not.in/out in die Pins geladen
addf not.0 servo-thread
net Start.not.out => not.0.out # hier wird not.0.out startbar gemacht

net Start.ext.an <= gladevcp.Start => or2.0.in0
net Start.ext.an1 <= hm2_7i76e.0.7i76.0.0.input-04 => or2.0.in1
net Start.or <= or2.0.out => hm2_7i76e.0.7i76.0.0.output-05 => halui.machine.on => not.0.in # Eingang not.0.in wird über den or2.0.out gesetzt

net Start.not.out => not.0.out => hm2_7i76e.0.7i76.0.0.output-06 => halui.machine.off
net MachineLED <= halui.machine.is-on => gladevcp.led_Startstopp

Hey, Ive been meaning to work on this and Dmitry's up camera, but before that I needed to build/install/configure my hardware with c axis before I started on this.

Nothing against qt/glade, but for simplicity I am trying to do everything in an Axis tab with tk/tcl/tkinter, and probably using usercommand file so that is my challenge.

The usercommand file Ive included is your initial file, but with a camera tab created in axis. I am using this as a starting point.

first hurdle : conflicting mainloops between axis and opencv

here is solutions, but Im trying to understand them first (I struggle with OOP)

Hello,  this is a bit off topic, but does the axis C component work perfectly? Thank you for your feedback

 

Hello, here is a functional version for port // that may help.

Thanks Peter,
Can you shed any light on whether the Mesa Modbus page (linuxcnc.org/docs/stable/html/drivers/mesa_modbus.html) relates to hm2_modbus?

My antique Dell Optiplex does not boot from CDROM anymore.  LinuxCNC 2.9.4, which has worked beautifully for many months, is now hanging the PC.  I attempted to use Package Manager to reinstall it.  It fails.  I tried to uninstall it.  It fails, so I guess that I need to reinstall from a USB drive, which is how I installed the now Zombie version.  I do not remember how I burned the ISO to USB drive from Windows.  ImgBurn only burns to CDROM drives.  Rufus does not give me a way to select a USB drive.  Help!

I don't have access to it today but I have an example GS10 VFD configuration for hm2_modbus
that I can post tomorrow.

It's been running on a test config for several months 24/7 without any issues.
 

Hi all,
I'm working on a machine with 7i96s for brains and a 7i75 for IO. I'm adding a fuling BD612 VFD so i can use the high rpms that the spindle is capable of, and I'd like to do this via modbus.

I'm aware of the hm2_modbus and mesambccc manpages as well as the docs page Mesa Modbus, but... I can't tell if they are referring to the same thing. It seems clear that vfd_modbus and mb2hal are different ways to do this.
I'd be grateful if someone could confirm that these refer to the same thing or different things...

It's clear that hm2_modbus and mesambccc are parts of the same system - does anyone have an example file(s) for setting these up? I'm happy to spend hours with the manpages and guide but get on far better reading and tweaking existing code, than trying to write it myself from scratch.

I've flashed the 7i96s_pktv3.bin bitfile successfully, not sure of next steps. 

Many thanks,
Andy

 

Does the drive itself power down on a fault?

I see where you're coming from. I very much don't agree with it, but that's just me.

I compiled my first kernel for RedHat 7 in 2001 I think. had no idea what I'm doing but since then, the novelty of compiling kernels - or anything, really - has worn down, mildly speaking. I'm a software engineer by trade, very lazy at that, and I prefer to a) update things as soon as possible, because the more versions I skip, the harder the update would be, and b) don't do work if I can avoid it - don't write code if I can use a library, don't compile my own kernel if a pre-built one is available, don't configure things that I don't need configured, etc., because if I do that, it means I now own that thing, and if there is an issue with it, it is my responsibility if not to fix it, then to at least investigate if the issue was caused by my changes.

I guess we have differing world views, and that's perfectly alright!

Config attached.

One of my previous posts as a zip archive of the rpi-image builder used to build the RPi5 & RPi4 images.

I'm of the opinion of keeping the kernel locked is not such a bad idea. It prevents users from messing things up.
It can also save "I've updated my kernel and I have xxyyzz issues" and sometimes trying to help some people out is like pulling teeth. Sometimes you have to ask for the same information a couple of times because for whatever reason they don't think it's relevant. And sometimes Linuxcnc is a users first venture in Linux, after maybe using Mach or grbl. There's no reason why an experienced user can't use alternative kernels if required or wanted.
And TBH I don't think kernel building is such a large task. The first one I built was around the time of Redhat 6.0 on a 486 with 32MB RAM (Maybe around '99 or something like that). Yes it was a very, very slow task. Back in the day were one had to hand edit files to get a dial up connection.

As for updates.....there's some user's that have machines running on Ubuntu based versions of emc2. Bit like the ecu of a car\truck\snow mobile\jetski\road bike\off road bike or similar, not often an owner will think of updates if any are available.
