My initial tests showed no violations of the limits for jerk and acceleration.

Has the track speed for circles G2/G3 been reduced in the past?

The speed with G2/G3 seems very low to me.

In the driver config string will set the mode to 2 which will enable both
the MPG encoder inputs and analog inputs.

Note that the encoder inputs are intended for MPG use and

1. Are fairly slow
2. Do not support index

You would normally use the 7I76EU high speed encoder input for the
spindle (TB3 pins 7..15)

Those values need a massive offset (-22900), has that been applied?

LinuxCNC 2.9.8, QtPyVCP 5.0.6, Qt 5.15.8 and Probe Basic 0.6.2

Updated everything like a week ago. Went with the stable release of Probe Basic because my linuxcnc computer is not connected to the internet and I have to unmount it and take it to a place where i have Internet to update it. So I do not update it that often and wanted the most stable version.

Should I update to the dev version?

@ m.ruefenacht

Do you have anything that you can share? I have a LCNC CAM grinder on my list of things to build.

I’ve been reading through AndyPugh thread, but honestly I still have no idea how to get it working in Probe Basic Lathe.
 

Whats the version? I saw this in a recent update and fixed it. The most recent should be resolved of that issue.

It is not specific to probe basic, but linuxcnc by andypugh, perhaps search kathe macros, i think there is a big thread on it and how to use and you can check if the macros are correct

Not sure on conversational, i dont use it and didnt build that it was a pull request from a user. Could be the macros for it need to be fixed

I’ve just updated, and now the screen displays correctly. The arrows seem to respond properly, but none of the conversational macros work—or maybe I’m doing something wrong when entering the values in the fields, although it doesn’t work in simulation either. I’m attaching a screenshot.The default RPM the spindle should run at when I press the Forward button still isn’t working.

By the way, I’m not sure if I mentioned it, but I’m on the dev branch.

I've been busy doing a complete rewrite of the core motion control libraries of linuxcnc to fix some pretty vig structural issues. In the mean time I've decided to buy a ised working CNC cam grinder

New PR from YangYang is ready, hopefully will be merged soon in master

This adds ruckig in the planner type 1
if you want to test it get the binary from

github.com/LinuxCNC/linuxcnc/actions/runs/21975584400

or build source from my repo

github.com/grandixximo/linuxcnc

Testers are welcome to report here or in github, thanks!
 

Hello gentlemen,

movement are incredible smooth ... basic shaping what I have tested till now is pretty ... but during movement at more points during simulation of rotation interpolation its jumping or woobing ... kind off braking and next accelleration 

most spiking during cloud of points are gone ... some spiking are still present but it a huuuuge step forward 

testing setup 2ms benchtop profibus master 3axis geany gui ... 3 servo axis with synchronized speed control loop at 2ms

some testing fault popups triggered during the movement of file 3_1001.ngc

I am still testing at default simulation file from past but splitted to separated operations ..

thanks a lot for your progress ... I am watching it every single day with mount open and box of popcorn to reading the edits ... 

regards E.

Please share min and max values calculation formulas for capacitive sense velocity for the optimum up and low signals for the fiber laser cutter. Eg to set up 100 volts 100/(fmax-fmin) for arc volt scale. Please correct if i am interpreting it wrong.

When i run my program, the IHS happens perfectly but when the the THC takes control the torch just gets the down signal and never goes up. Kindly help with any formulas with these three parameters.

-Cutting voltage set to low
-Voltage readings to high
-Voltage scaling and offsets not set correctly
-No arc voltage reading at all, can be from inverted polarity into THC, wrong wiring from THC, THC input for high voltage while output from plasma is divided
-voltage divider in plasma/resistors set incorrectly
-broken wires from plasma to THC input
-etc
