Retrofitting a 1986 Maho MH400E

Category: Milling Machines

Thanks Tommy,

I have worked through troubleshooting, and have the machine up and running again.

The EXE's are not powered by the Indramat power rails. The Indramat received 2x 90VAC (X and Y) and 2x 140VAC (Z) from a transformer straight off the mains. The X axis EXE still uses an original lane of the old three axis EXE board, and thus needs both 5VDC and 12VDC supplies, which are powered downstream of the main isolation transformer.  X and Y are on 601D EXE's which only need 5VDC, on the same PSU as the Z.

It seems like a combination of issues.
1/ I had an addition relay so LinuxCNC can also control the Z axis brake, which in the original set up was only controlled by the Indramat. The consequence is that the motor was fighting the brake briefly on every start up. Not sure if that has caused further issues.
2/ Errors in setting Ferror verse Ferrormin, Leaving Ferrormin too tight.

Axis    fError.    fErrorMin
X.           0.5           0.2
Y            0.5           0.2
Z             20             1

The 20 was obviously an oversight which I forgot to set after finishing pid tuning.
Question: What would be a typical value for fError and fErrorMin for a machine like set with 2400mm/min max rapids? Is 0.2 and o.5 really that tight?

3/ Not adding any intergral in the pid tuning, once I had P, FF1 and FF2 set. There is a constant offset in steady state motion.

4/ Suspect that using the 220 weight way oil recommended in the MAHO manual might be too thick in winter.

I have removed that 19K2 relay, removing linuxCNC from the brake control and returning it solely to the Indramat.
I have opened up the fError and fErrorMin values, and am now working to find sensible values.
Just playing around to find the right value of I for each axis.
Cheers,
Mark

I did notice on a previous installation that the sources only included the CD.

Let me investigate further.

Hello rody,
thank you for your input.
The old way is working too. Synaptic use the old one if you add there sources, too

Debian trixie uses the new deb822 format so sources.list is no longer used.
Instead  look in /etc/apt/sources.list.d/debian.sources for the sources in the new format

there is the package "python3-distro" in Trixie.
But you have to configure the sources correct.
Please look here:

I don't see any Debian repositories how did you install the OS?

I'm downloading Debian 13 and installing that on  SSD for testing.

LinuxCNC 2.9.8 Image with Debian Trixie

Category: Installing LinuxCNC

Hello,
i installed the new LinuxCNC 2.9.8 Image with Debian Trixie and think the installation is not "ready to use" and need work.

First add the Debian repositories:
With
sudo nano /etc/apt/sources.list
add the lines:

deb deb.debian.org/debian stable main contrib non-free-firmware
deb-src deb.debian.org/debian stable main contrib non-free-firmware
deb security.debian.org/debian-security stable-security main contrib non-free-firmware
deb-src security.debian.org/debian-security stable-security main contrib non-free-firmware

After that:
sudo apt update
sudo apt upgrade
sudo apt autoremove

Select and activate your language:
sudo dpkg-reconfigure locales

and your timezone:
sudo tzselect


Best regards

Michael

P.S.: With this Trixie-Image the old raspi-firmware bug seems to be away.

I would try the realtek dkms driver and the additional RT kennel tuning tweaks in my YouTube guide and I think you will have good performance


If you do buy a new NIC card.definitely get  an Intel card preferably one that supports time sensitive networking (TSN) Eg i210 series en.wikipedia.org/wiki/Time-Sensitive_Networking this gives real time network performance (finally) and is supported by ethercat. Take care as some of the intel cards have different versions and the entry level card for that model does not support TSN. Not sure if this will require slave level support.

First off, I'm not a computer expert. I've followed all the steps on the website step by step. I've attached a few screenshots. Can anyone tell me how to solve this problem?
