Just got info from 2 suppliers that there are 16GB RPi 5 for sale. No mention of any other hardware updates.

What I would do is get a basic working configuration with pncconf.
This means setting the machine limits, scaling, directions, timings,
velocities, and accelerations. Once this is working I would then worry
about tuning for best performance and  special features like drive fault
operation.

That is, don't get the sandpaper out when you are still in the chainsaw stage.
 

I don't know how to respond to this, other than to say that's exactly what I'm doing.

My advice to you is to improve your documentation, because that is the real issue here. I'm trying not to bother you on the phone or email you directly, but I need to know how this software works, in order to use it. It just isn't set up for a newbie to walk in and paint by numbers, and it should be, for a simple 3-axis benchtop router with Clearpath servos. This should not be a science project.

I have made parts that have been in Space. If you're looking for a test-case for someone willing to follow directions, I'm your guy. I just need the directions!

Thanks for your answer. Can Gmoccapy screen be used for this kinematics?

I'm sorry you find the documentation and help provided inadequate. I'm sure those volunteering their time here to help others like you could easily find more rewarding activities.

--update--

i changed the base period and servo period
base perio is 22000
servo period is 90000
and the scale is 50(1 rotation is 10mm | 10 mm equal 500 pulses it is good)
and i take max 2500rpm for jog speed(25000mm/min)  
when i decrease the base period for example 20000 i take maximum 3000rpm but sometimes program give following error so that 22000 is good

and also when i open the axis program
"Unexpected realtime delay on task 0 with period 22000
This Message will only display once per session
Run the Latency Test and resolve before counting"
What should i do?

If you want to make the results of the discussion more visible you can edit the first post.

Thanks
 

I wish you hadn't. Some thoughts:

1) You would save yourself a lot of time and energy by creating a default configuration that works for a common machine type, like a router, and then explaining what special considerations should be made to account for unique machine types, rather than the blank canvas it is now.
2) Update the documentation! It's basically useless for unseasoned users, in its current state.
3) You should strongly discourage your half-dozen most prolific forum posters from only partially answering questions, which is more confusing and time-consuming for the person asking the question(s).

I have extremely common, made in USA axis motors and a brand new Mesa Board. This should be a slam dunk, five-minute exercise, plugging in a few values and following explicit instructions, but instead I am several threads deep and I know less now than when I started. Tormach mills have Mesa boards, and run PathPilot, which is just LinuxCNC, so what I'm doing should have already been well-documented.

I made the second thread as a place to store the correct answer in its own little place on the forum, for future reference. Otherwise, I, and whomever else might need the information, would have to wade through several hundred entries of me arguing with people for weeks to get a simple answers to simple questions.

hello PCW
Actually i download ini and hal file from byte2bot com because i bought parallel port rpi hat card from there

the latency test writing

Servo thread(1ms) max interval : 1003960ns | max jitter 3960 ns | last interval ~ 1 000 000 ns

Base thread (25 us) max interval : 30111ns | max jitter 5686 ns | last interval 25000ns

Should I change the base period and servo period values?

Thanks

The tool changer system doesn't matter. I have several lathes with different tool change systems. They all work fine. But for a lathe I don't want to use the command T1M6G43H1, but only T1. Machines google baseball with Ladder ATC can do it.More complex machines, such as Sauter, it is better to make a carousel  component. And here it does not work like that.
 

Yeah, the different lathes have different tool change systems, and the command T1 may work for some machines but not others. Or more complex machines like Sauter, using a carousel component is a better approach as it allows more flexibility in managing the tool changes.

I pushed a fix.
It was cause by RIP and Installed versions looking for a different environmental variable for the same info (LINUXCNC_HOME and EMC2_HOME)

This should fix the errors you see.

Change sync0Cycle="10000000" in the xml file to sync0Cycle="*1" and try it

Rod I mentioned it via email what needs to be done.

This is an excerpt from the patch for arch/Kconfig
Without this small edit, you don't get all 4 selections when you select which preempt model you need.

The patch adds this function:

The best thing would be for LinuxCNC to remove its dependency on /sys/kernel/realtime and check some other way. That's the only thing keeping LinuxCNC from at least starting up on an unmodified 6.12 kernel (caveat: I haven't cut anything with it yet).

That is the problem. I now notice my designer works because I too have an installed version of linuxcnc. I'll fix this soon.
