The m600 uses a Realtek MAC so likely needs the DKMS driver
(the built in Linux one is defective and has random 10 ms or greater hangs)

Take a look at this thread:

我觉得你可以去BiliBili这个网站上看看，有专门讲解这个的

Now I saw the device.
My idea was if there will be an error if the speed/acceleration is low.

I have mine set up using 1 of 2 ways, both are setting in the RPi

1, using the BOOT pin on button, this way you can turn off RPi IO power and still boot from halt using a button

2. Boot using the one IO pin on the header, and boot with button

the 7C8x is still powered at 5v 

It is used for decorative wood carving (signs, plaques...). Carving 8 pieces at a time. Originally it only had a single Z axis. with a hand screw for fine adjustment of each spindle height. This was difficult to maintain and adjust the Z depth between each spindle for varying material thicknesses or when changing tools. So I recently rebuilt the machine with a separate closed loop stepper motor, ball screw and linear guides on each spindle. I also replaced the old single servo, 12ft torque tube, rack and pinion drive system for the Y axis with new larger linear ways, two ball screws and 2 servos. Then after doing all of that work I found out that the majority of the slop in the old system wasn't due to compliance in the old drive train, but fex in the bridge. So I stiffened the bridge, and it is greatly improved. (The X also got new ways, and replaced a belt driven lead screw with a direct drive ball screw and added tool touch probe and probing routine.)

This seems to work for me:

Hi guys!!! Thamk you Tommylight, Zmrdko and PCW

I managed to solve the latency error by isolating one cpu of the processor. Now it doesn´t trigger the message, but there´s a new visitor....

Now the annoying "Error finishing read" appears too often, sometimes even while running the small "Linuxcnc" test program G-code.
The computer is a basic Lenovo tiny M600 with an Intel Celeron (2 cores). The ping values doesn´t seem to me to show crazy high msec values.

One more time, I´m completely lost in the journey!

Hi, the Mesa 7c80 board is a host for the Rpi 4B.  Looks like: desertshedstudio.com/wp-content/uploads/2023/01/7C80_RPI4_1.jpg  So supplying DC to the 7c80 (orange terminals) powers up the Rpi.  Which means that as soon as power is applied, it starts booting.

Then when Debian is shut down, the 7c80 has no way to unpower the Rpi, so it stays running.

We can control machine "on" power easily from a seal-in relay.  But has anyone devised a way to shut down the 7c80 automatically when Debian terminates?

We distinguish between emergency off and emergency stop.

Yes, you need a physical switch, but it can be handled by software. It even has to be in many cases, as a safe shutdown/braking of the machine must be ensured.

in the english version are many more types:

You could launch LinuxCNC with a script like so


and connect the pin gmoccapy.h-button.button-9, which exits gmoccapy, to an external button.

How do you have your Z axis configured on your machine? Specifically where do you have the machine Z zero position set up to be? If the command G53 Z0 moves your machine down to the table surface, that would be your problem.

The normal convention for a milling machine setup is to have the machine Z zero to be at the top of the spindle travel (or bottom for a moving table like the knee of a Bridgeport.) In other words the tool as far away from the table as possible.

Not that you can't configure your machine to have Z zero at the table surface. You can, but you will have to be careful of default assumptions often used in most g-code. You will have to watch out for commands such as G53Z0 often used at the beginning or end of files and replace them with something more appropriate for your machine. And for tool changes you will need to set up and configure a safe tool change position for G30 and add the line "TOOL_CHANGE_AT_G30=1" to the [EMCIO] section of your ini file.  (And even then Linuxcnc might try to move to G53Z0 before going to the G30 position, so I'm not 100% certain this will even work as I've never tried to do it.)

But it is easier and safer just to configure the machine to the usual convention of machine Z zero at the top of Z travel. Then use work coordinate offsets and or tool offsets to move the Z zero position to wherever you need it to be for your milling file.

(Also, yes the "TOOL_CHANGE_QUILL_UP = 1" means that the machine is going to move to G53Z0 at a tool change command.)

As luck would have it now we get to running this on a real machine (and a sim) it fails.
It seems the G91 is being inserted too early. It should be inserted after the G53 so an error is not generated
I've attached the filter we worked out earlier and a new gcode file.
 

Any help to fix this would be appreciated.

Hi...new to linux here ...bought 7i96s and have powered but when trying to open Mesa Configuration tool...which I think I need as everything looks so foreign coming from mach 3...but when I open in debian I get error " Dependency is not satisfiable: Python 3 packaging.??

Thanks for any help,

Rick
 

I removed the dependency on python3-packaging and still don't know why it's not in the Debian repo when using the LinxuCNC live CD.
