Problem is that $1 contains a float which bash can't handle, so try:

I believe these lines were the problem:

net tool-prepare-request <= iocontrol.0.tool-prepare
net tool-prepare-confirmed => iocontrol.0.tool-prepared

Not sure if those came from PNCconf, but I commented them out and it seems to have resolved the issue.

Mach 3 is at a point where it is hard to run unless you have a really old version of windows. i used it for years until i hit issues in windows 10. so i would make the switch which i did do
when it comes to plasma and THC Linux with Mesa has probably the cheapest THC solutions out there but I'm in the US so duties and taxes could factor into it to some degree.

Hello PCW,
I checked the hm2_7i76e.0.packet-error-total and got 57 errors about 45 minutes. Is this too much?

I don't understand these packet losses - (my PC is a lenovo ThinkCentre M92p Mini-PC, Intel Core i5-3470T 2.90 GHz 8GB Ram, in the latency Test I get readings as shown in the photos, first at start, Servo 4000, Base 5608, after 30 minutes surfing, coding in Vcode, doing sth else: servo 82040, Base 24542, I set servo thread in the INI file to 1.600.000.
Kernel release 6.1.0-29-rt-amd64, Kernel Version #1 SMP PREEMPT_RT Debian 6.1.123-1 (2025-01-02)
What do you think?

I did the most Latency tips in this thread: forum.linuxcnc.org/38-general-linuxcnc-q...ead-and-irq-affinity - I disabled hyperthreading, power saving, virtualisation, TPM, turbo mode, ACPI, APM, Audio,, kernel isolate core 0 for interrupts - quiet irqaffinity=0 isolcpus=0. I bought a new network controller with RTL_8125 chip,  optimize my network connection with sudo ethtool -C eno1 rx-usecs 0 at any system start. Kernel release 6.1.0-29-rt-amd64, Kernel Version #1 SMP PREEMPT_RT Debian 6.1.123-1 (2025-01-02)

Anyways, I dont have servo motors with encoders wired to the MEsa 7i76e, so I cannot calibrate in live mode. I just set the FF2 to 0.0003 as you said. Same results as yesterday, not often but sometimes i get that motor-0-position errors.
Maybe my PC is too slow for a Linux system? Any suggestions?
Thank you so much for your support!

Hi all. I need help with my custom M code I've started to write. I ran into a problem right at the beginning with an "if" statement. My M code should be M105 P100 and it seems the "P" value isn't transfered into the M code. 
​​​The M code always outputs "else" condition so "operand" isn't 100 as expected. 

I also wrote a similar M code with "case" and there the P value is recognised by bash. 

What did I do wrong here?

With a specific bios setting Linuxcnc does open and axis moving smooth, but at start up i get "unexpected realtime delay on task 1.

Sorry for the douple post. Didn't even realize it happened.

As for the problem, I don't think it is an issue with the LinuxCNC images. You are right that it is likely a general problem that would show on a non-LinuxCNC image. I figured I would ask here because you guys seem very knowledgable about not only LinuxCNC, but Linux in general.

That said, I have searched about this problem in general RPi forums and internet searches. I did a lot of that before posting here. There are reports of others having this problem but all of the solutions I have found on this say to go into raspi-config to change things, but the LinuxCNC images don't have raspi-config and menu-config doesn't have the same options. Basically what everything I have found is getting at is forcing the resolution for the login screen to a resolution that works with the monitor.

To be more clear as to what is happening, when the Pi starts to boot the monitor wakes up and pops up a little info window showing what resolution it is being driven at. This little window is a display thing, not a linux thing. Anyway, I can't remember what resolution it starts at with the verbose text, which appears fine, but when it gets to the login screen the little window pops up and shows the driving resolution has changed to 1366x768 @ 60Hz, which gives the skewed image in my previous post. At this point I can type username "cnc", tab to password "cnc" and it takes you to the desktop. Initially the desktop is skewed like the above picture, but you can make stuff out. If I navigate to display settings and set them for 1400x1050 @ 60 Hz the image is normal and everything is fine. If the machine goes to sleep or reboots, once it goes through the login screen again, the resolution is reset to 1366x768. If I can force the login screen rsolution to be 1400x1050 I think all will be good, but I don't know how to do that.

So, i could open Linuxcnc ones after i got a error message on start up, but after reboot i get the error message all the time, so i am not able to start linuxcnc.
I wanted to attach the report file, but cant upload that file type, so i just paste it here. sorry that but i want out of the workshop now, i have enoug and mz hands a freezing.

Homed...!
After getting my head around these units, then I found the max acceleration set to something monstrous I'd entered randomly in pncconf, (mildly entertained by setting so slow it looks almost drunk). Any way, the final realisatioin was looking at the position trace in halscope, expanded vertically, which showed that its goes in reverse back over the limit switch after finding the index....
Yes HOME_OFFSET needs to be negative DOH.
I had in my head that anything moving the spindle to the right is a positive number, but I think that in fact when the index is picked up, that sets a zero, and to home at zero, this point we've found has to be at -25.4 in these coordinates.
Ha

I guess these old tools are not in use any more.
I want to generate G-code for a simple engravings using single stroke font. Could anyone point me in the right direction of some simple and free program/script that can do that?

the motor move with it's speed when use linuxcnc app but this app can't do what I want from the machine if there is any way to program my python code to work as linuxcnc app

Update: After doing 1-2 changes in the bios, i can again enter linux and also do the latency test, sometimes.. I open it and it shows 0 everywhere (intervall, jitter , last interval).
When i close it and open it again, it shows again 0 everywhere, but after a couple of seconds it shows latency as it should. Now i opened glxgears and youtube but the jitter did not change a lot from 23.000 to 24.769.
I will soon connect the machine and test it. If it works without unexpectec realtime delay message on pop up, then its a good sign and maybe i then just need to make some adjustments in bios or grub config.

EDIT: just thought its looking good, but machine just freezes out of nowhere and i just wanted to start linuxcnc and check if its working, but I also get a error message that i knew how to solve with a terminal command, but due to fresh install that command is not anymore in my terminal history, but i get:
Permission denied.
/custom.hal5: waitpid failed hy_vfd vfd
....

So, beside freezing pc problems, i got a new problem to fix. Amazing.

EDIT: i have found the command and now linuxcnc is starting without unexpected realtime delay, axis moving, but it sound a bit strange, but smooth but with small stops between smooth movement. I will try to adjust bios cpu settings.
