Yes. I tryed. Result was the same

Did you try writing one of the standard supplied EPP bit files?

The official LinuxCNC 2.9.4 image for arm64 is installed on a Raspberry Pi 400. There are strange partial graphical glitches in browsers, such as some pages or partial horizontal section of the page not displaying properly, while the rest is fine.

This was tested with Firefox ESR, but Chromium was also installed, and for example, the settings page for Chromium never displays properly. It would appear the underlying text and buttons/links are present but not visible, except by sometimes mousing over them. 

The problem appears to be only in browsers, not other applications. Youtube in either browser is also unusable, with graphical glitches on the player controls (YT buttons like play/pause/settings are either invisible or look corrupt).

Similarly, when opening PDF documents in browsers, the control buttons along the top of the document for Zoom/Download/Save etc are often invisible, but still present if moused over.

Also, Youtube video playback is extremely laggy, and that is including after removing the isolcpu=2,3 option. The goal on the Pi is just to familiarize with LinuxCNC and set up configs, not to run machines on it, so I'm not too concerned about the latency penalty in this case.. 

Has anyone else experienced this problem? 

I had an old Bridgeport mill that had had heavy production use. After getting some level of proficiency with it, I was having BIG problems getting things to fit together. So, I'd make some device, and then in a different setup, make a cover with screw holes that were supposed to line up. They didn't! It turned out that the Acme (trapezoidal thread) screws were more worn in the center that at the ends.
This was enough so that there was a large positioning error when moving from one end of the screw toward the middle.
Tommy, so this machine has ONE servo motor and clutches to the various leadscrews? I've heard of such machines, but never seen one. That does kind of match the amount of electronics in the thing.

No it does not.  After unsucsessful firmwareI  I tried to boot from the second EEPROM (W3 in the low position). But Mesaflash not founded 7i90 and 2 leds glowed ( power and int ) opposit to 3 in first case.

Looks basically ok
Maybe the machine does not think its homed
You should be able to jog without homing by adding
the joint jog pins:


# ---Handrad-Signale zu Mesa Encoder - shared MPG---

net axis-selected-count <= hm2_7i80.0.encoder.03.count

# ---mpg signals---

# for axis x MPG
setp axis.x.jog-vel-mode 0
net selected-jog-incr => axis.x.jog-scale joint.0.jog-scale
net axis-select-x => axis.x.jog-enable joint.0.jog-enable
net axis-selected-count => axis.x.jog-counts joint.0.jog-counts


# for axis z MPG
setp axis.z.jog-vel-mode 0
net selected-jog-incr => axis.z.jog-scale joint.1.jog-scale
net axis-select-z => axis.z.jog-enable joint.1.jog-enable
net axis-selected-count => axis.z.jog-counts joint.1.jog-counts

sets selected-jog-incr 1.000000

Was gibt beim
ip a
in terminal?

Does the alternate EEPROM still have a valid image?
(that say mesaflash --readhmid works with)

Sorry, attached the wrong file...

This should be right:

Those Maho's are already CNC from the factory, meaning they have motors on each axis and have ballscrews, so very easy to retrofit.

Means a similar retro fit like these ones?

Servo Zentralantrieb in allen drei richtungen
means
central (single) servo drive for all 3 directions
So not hydraulic, but the tool lock is hydraulic, both for horizontal and vertical head.
In short, retrofitting to full CNC would require removing the central drive and gearbox and adding motors to each axis on the hand crank, most probably.
Also, normally, this type of machine uses trapezoidal screws and brass nuts, so have a lot of backlash, that can be fixed in software to a certain degree, but do not expect much precision.

In one of the pictures in a sales catalogue it says There is a WF5 and a WF5NC, which seems to be a control to move.

The attached picture of the original post clearly says WF5 NC on the machine tag. 

It says "punkt-strecken-gesteuert", I guess that means it can move one axis from a given position to another given position at a time?

 

p.s. that thing must be from the last century , older than computers.
 

Hello.  After incorrect firmware loading all three LEDs on the board light up and mesaflash not found board. I try jtag flash. The firmware is uploaded successfully and light up only yellow power led. Mesaflash found board, but when I try to write a bit file an error occurs: Error: BootSector is invalid.
--fixbootblock doesn't help. What shoud i do to wrtie bit file in EEPROM?
