I cam from a "working" mach3/uc100 setup over to a 7i96s setup. K4030 drivers. terminal pings the mesa board. I have dir +/- and step +/- wired to the k4030 and 7i96s. a cell phone charger to power the 5v of the 7i96s.
steppers dont move. i have no limit switches hooked up yet and i configured the settings to not need to home first.
i tried connecting the 24/36v psu ground to com on the 7i96s, i tried connecting the 7i96s 5v to the dir + & step + (which is how mach3 was configured; and the dir/step - was 2 pins on the serial board).
when i connected 5v to dir/step +, and started linuxcnc, i did get "unexpected real time delay on task0 with period 1000000"

what do i have wrong?

once i get this figured out im going to make a video on all of this to help me next time and others. i have been on the struggle bus thus far.

side note, with just the 5v input and dir/step +/- hooked up, i get 5.09v between gnd & 5v, i get 5.09v between step + & gnd, i get .23v between dir - & gnd, and dir + to gnd i get 4.81v. on unused step/dir ports its the same except i dont get the .23v reading, its 0 instead.
 

Details and instructions for updating from 2.8 to 2.9 are covered in the doccumention. I don't think there were any significant configuration changes, and none that would be incompatible with a 2.8 config.
linuxcnc.org/docs/stable/html/getting-st...dating-linuxcnc.html

I don't think there are or were any changes in Classiclader for version 2.9

Change log for 2.8 to 2.9 is here.
linuxcnc.org/2023/11/04/LinuxCNC-2.9/

Hello, I would like to know if it'a possible to install the new version over the version 2.8 ?
Are config files compatible ?
Is the classic ladder compatible ?

Is the gui of the classic ladder better in version 2.9 ?

what are the main difference of the new version ?

Ok, I increased the step time and set it to type 0, it works, but I set everything to 10000

Hi.

Teile mal deine Tooltable. Also entweder screenshot oder die Textdatei.

Das Kalibrieren ist entscheidend. Ich habe das so programmiert, dass der tolltable Durchmesser nur für Sicherheitsfeatures relevant ist. Alles andere erfolgt durch die Klaibrierung.

Its most likely a hal file setting thats wrong: The step length

How can I diagnose why it's not type 0? Maybe it's the Ethernet cable's fault?

All modes work (0,1,2), but the steplength setting
only  affects the step length in modes 0 and 1.

Is this correct for it to work on stepgen type 2?

Maybe you have the step length too short for the scope to catch

Hi.

I recently wrote some macros for a pyvcp panel. Tilman and I called it easyprobe. (github->hausen8->easyprobe) In the newest version I implemented a routine to measure as many points one like an write the values in a txt file.

So yes. One xould build some kind of panel or screen and get some usefull results. Maybe of intrest.

Yes i see signal type 2 step length 5us

Do you see a signal with type 2?

What is the step length set to?

Thank you sivaraj.
