NativeCAM 2.0b — Python 3 & GTK3 port for LinuxCNC 2.9 / Debian 13 Trixie

Category: NativeCAM

Hi axemas, Thank you for all your efforts.

I’m testing the 
nativecam_2.0b-4_all.deb package on a clean install from the Debian 13 Trixie ISO
. The package installs without errors, but the NativeCAM tab inside LinuxCNC appears blank.

To make sure I wasn’t mixing versions, I completely removed all previous NativeCAM files and reinstalled the [code]-4 [code].deb.

After installation, [code]dpkg -L nativecam shows the package installs into:
/usr/share/linuxcnc/aux_gladevcp/NativeCAM
/usr/bin/nativecam
/usr/bin/ncam

My INI file contains the following entries:
[DISPLAY]
EMBED_TAB_NAME = NativeCAM
EMBED_TAB_COMMAND = nativecam
NCAM_DIR = /usr/share/nativecam

LinuxCNC launches normally, but the NativeCAM tab remains empty. When I run [code]ncam (or [code]nativecam) standalone from a terminal, I get a stream of warnings and deprecation messages. Here are the last lines:
[/code][/code][/code][/code][/code]

I’m trying to determine if additional steps are required to make it compatible.Any clarification or guidance would be appreciated.Thanks.

Schaublin 125-CNC retrofit.

Category: Turning

my best guess, shaublin just wrote a very difficult to control pid algorithm with slow speed seeking, and they had a team of engineers, and you'll notice , they got rid of the variator, sometimes the best part is no part. for my suggestion with the closed loop stepper, KEEP the existing worm gear angle driver, make a coupler and adapter slap a stepper in place of the existing AC motor. keep the acme screw and angle drive, looks doable without disassembling the machine from photos. Also my path is, 4 wires from you 2 from the psu and 2 step dir  card. it doesn't need to be decimal perfect.

New forum member needs help to get startet with LinuxCNC

Category: Basic Configuration

Hello everybody!

I’m new to this forum and new to linuxcnc.
I own a 3-axis gantry mill that I used to control with mach3 connected to a USB Motion Controller.
The controller died a while ago and since I didn’t have any milling projects the machine has been sitting in at the corner for quite a while.Recently I decided to bring it back to life. The goal now is to to get rid of Windows and USB. I got a 7i92 Board that I could bring to life. I have installed linuxcnc from the latest available .iso file. In addition I have a WHB04B Pendant available, that I would like to integrate.
Linuxcnc is not very intuitive for a beginner, but I managed to get it working to some extend. I used an „axis“ configuration and could connect the pendant, I got to a point where the display on the pendant was updated when I moved the axis in linuxcnc and keypresses on the pendant showed up in linuxcnc, so the hardware/config is generally working, but I never got jogging to work. By now I have obviously tried too many things and messed up the configuration in a way that it is not working at all any longer.
To have a clear and clean configuration to start with, I would to prefer to restart from scratch.
So my question is:
Is there any HowTo and are there sample configurations that include the WHB04B?
Since I’m new to the world of Linux I assume the learning curve will be very steep.
Thanks in advance for your support!

P.S.
If this leads to success, I’m happy to log the details and to compile a step by step howto for beginners, since I couldn’t find any.

Retrofitting an old industrial CNC mill with EtherCAT components - MAHO MH400E

Category: EtherCAT

Thank you Tom :)

The current plan is to mount an inductive sensor on the motor shaft and let the VFD count the pulses. That way no additional EtherCAT hardware is required and the VFD (or LinuxCNC) is able to read the motor velocity for a future PID controller or similar. An encoder is not well placed at that spot, because the vertical milling head has quite a bit of dead-zone/backlash. To keep it as simple as possible while being accurate, we decided to mount the encoder on the milling head

Retrofitting an old industrial CNC mill with EtherCAT components - MAHO MH400E

Cool project! I like your PDF!

To the spindleencoder a hollow shaft encoder by calt on AliExpress is really low priced and should perfect fit the spindle.

To be honest i never understood why people mount an encoder to the head that is flipped away in horizontal mode. Even if you use it not that often - 50% of cool Features can not use rigid tapping. so you even less will use the cool horizontal mode. not a good place in my opinion. just mount the encoder to the motor and scale with the gearbox and you are happy for the z signal you only need an inductive sensor or similar on the horizontal spindle for reference.


greetings

Retrofitting an old industrial CNC mill with EtherCAT components - MAHO MH400E

Category: EtherCAT

Since we operate in vertical milling mode 99.9% of the time, we need to read the spindle position somewhere on the vertical milling head. Our current plan is to design and manufacture a resin (or similar) replacement part to substitute the white fan/impeller (or whatever the exact term is). By carefully cutting slots on the back, we should be able to mount an SSI encoder behind the hydraulic drawbar and drive it with a belt. If you have a better idea, let us know :)
We do actually have a second unused channel on the SSI encoder input terminal, eventually we will integrate the horizontal spindle too, but i don't think so.

I still don't understand why the US made it so complicated. Here in .AU all we have is  single phase 240v (which Is slowly getting watered down to 230v or even 220 v to match some overseas countries) and 415 volt three phase. 3 Ph circuits can have an optional neutral wire and you get 240v from any phase and neutral. 380v I think is allowed but some people recommend using a transformer if running 380v machines.

Nice Choice. It evens support IEEE1588 Precision Time Protocol that is behind TSN (Time sensitive networking),
One day , we will have Ethercat slaves and possibly even Mesa FGPA's that support TSN

Geekom A5 pro: poor latency, BIOS settings was created by donaulaender

Geekom A5 pro: poor latency, BIOS settings

Category: Computers and Hardware

Hi, i have a geekom a5 with amd ryzen 5 running linuxcnc - debian 13 rt and a mesa 7i69s. after setting the mesa to 10.10.10.10 and the mini pc to 10.10.10.11 i got stable connection with reliable ping. however the latency is way to bad for linuxcnc. i already set isolcpu and others in grub but without success. no i am preparing to get into advanced bios. does someone know the settings to bring me foreward. thank you

Where are you planning to install an encoder in the spindle drive?

Europe, so you do NOT have 3 phase 230V, you have 3 phases where each has 230V exclusively when used in conjunction with neutral. Otherwise, you have only 3x380V.

 

Sorry to hijack this discussion
That makes sense. Finally!... that solves a question that has mystified me a long time. Why 380V? Well, it does make sense.

Here in US we have everything except  380V:

(1) We have 1 phase 120/240V with two lines 120V to neutral or 240V between each other.
(2) We have 3 phase 480V with 277V to neutral and 480V between each other.
(3) We have 3 phase 208V with three lines 120V to neutral and 208V between each other.
(4) We have 3 phase 240V with 120V to neutral on two lines, 208 to neutral on the third line, 240V between any two of all three lines. This kind of service is hardly installed new anymore, but still exists. Used to be quite popular with just two transformers, they actually skipped the third transformer. It is actually an extension of (1) above by adding one transformer on the power entrance.

Listed in order of popularity among my current customer base.

With regards to ethercat vs mesa it looks to me, based mostly on forums posts, that the mesa route is safer, more tested and less potential problems, does that sound about right?

Yes, EtherCAT is easier to wire in and that is pretty much where the fun stops. It is a very nice idea implemented ...not good.
And, yes i will order some cheap EtherCAT drives and play with them, gladly, but i have to order through friends abroad and wait ... and wait...

Main problem is they require 380v, 3-phase and 17kW of it... A bit more than I have available in my garage. So the plan is to reduce the power somewhat (especially for the 10kW spindle motor), given the machine is only going to be used for hobby projects, and get it to run at 230v 3 phase.

Europe, so you do NOT have 3 phase 230V, you have 3 phases where each has 230V exclusively when used in conjunction with neutral. Otherwise, you have only 3x380V.
That is something i have to deal with at least once a week here as some smarta$$ yanked a motor from a machine and plugged it in the 3 phase socket and of course that ends up in smoke pretty quickly. About a month ago checked a board from a Tesla car charger that went up in smoke here the instant the fuse was flipped up.
In general, anything that says 3x230V but does not use neutral, do not plug in EU 3 phase sockets.
