at the moment jerk-cmd are debug pins, they are not to be used for machine control, because the current calculations try and do best we can to calculate and blend quickly in realtime, there are knowm spikes in the jerk-cmd, please look at vel-cmd and acc-cmd everything looks very good to me there, there are no violations there, if we were to respect jerk cmd strictly the interpolation would not be able to run as fast as it does, but we could look at making a stricter mode viable as an alternative, or possibly the default if that's what the community needs.

@PCW

try with

setp ini.traj_max_jerk 3000
and
setp ini.traj_default_jerk 3000

I do not get acc violation with these values, can you confirm?

this tool is embedded into the AXIS gui:

Menu -> Machine -> Calibration

Thanks! That was the problem.
I also set the P value back to 250 and FF1 to 0 and max output to 300.
The other settings were causing a following error, but now everything is working great and milling round circles now.

What is the program you were using to change the joint values in the video? Looks like you can change them without restarting linuxcnc?

I didn't tested by launching from terminal. But I tried with skr3 board which was tested working and octopus pro with newer(tmc5160) and regular remora both have same problem.

He did but you probably did not get a notification as he edited the existing post.

Share the gcode please, and we will take a look next week

Probably get no response, but figured I would try, I am currently in process of doing a similar retrofit and was trying to get a few more details on the homemade encoder for the spindle.  The fact that the OP has not posted here or on Youtube in three years makes me think I am SOL.

Thanks Chris,

I also notice previously I had 0 as deadband and the steppers all worked well. With 0 now they hunt 0.000 to 0.001 so are contstanly vibrating. I had to set the deadband to 0.001 to stop it. There are 6400 pules per rev and each rev is 5mm.

If you need anymore info please let me know.

Regards

Been poking at this a bit, finally got new ideas on this servo valve height control setup:

The servo valve pwm signal is basically a 'power' level command.
 The user interface commands position orders at more or less adjustable velocity.
 My PID controls position... I thought I might use pid.max-limit to control the velocity, but I do not expect that to work well for controlling non-linear hydraulics.

Aha! I think a second PID will serve the speed control. I have to try that.

The name must always match

file:
myfile.ngc

in the subroutine:
o<myfile> sub
  some code
o<myfile> endsub

call the sub:
o<myfile> call
 

yes I bet that's it. I notice you are using metric, so .006 is pretty small.
I'll try to track down where the rounding error comes from.

In this case I had a dead simple routine named 'test.ngc' that called a dead simple subroutine named 'my file.ngc'.

No idea if this is the issue, but easy to test so:
-no spaces in file names, this was an issue way back, not sure if it still is
-use a file name like: my_file.ngc

I have always had problems with named subroutines but lately I cannot get them to work at all.I get the following message;

LinuxCNC Error Near line 4 of/home/rpi-first-boot-wizard/linuxcnc/nc_files/Utility_G_Code/test.ngc:Failed to find sub 'Omyfile.ngc' before EOF

In this case I had a dead simple routine named 'test.ngc' that called a dead simple subroutine named 'my file.ngc'.

The location of the files and subroutines was called out in the .init file.

I have used named subroutines in the past.  I now use Raspberry Pi 4 and 5 with Axis 2.9.4 versions.

Any fool proof method for handling these subroutines would be appreciated.
I have a boat load of specializedsub routines lying dormant.

Thanks for reply. That changes resolved the issue of not compiling on trixie, there was also some error on line 505 column 69 of remora-spi.c. I edited that, I don't if that's correct, but that line will only be used in case of using rpi5, don't bothered and compiled the remora component. But still same issue on trixie and bookworm.

Hope some will help.
 

Sorry if I ask obvious things that you already checked, but what message do you have if you start LinuxCNC from a terminal, and then try to get out of emergency stop state? I don't have an SPI version, but on the Ethernet version I get an error message like "Bad SPI payload = 0" if I don't have communication with my board.
