PCW, 

Thank you.  Sorry for the crazy number of posts today.  I was trying to keep things up to date and wasn't sure which problems I would figure out and which I wouldn't be able to. 

This is what I have in M101:
#!/bin/bash
halcmd setp hm2_7i96s.0.ssr.00.out-00 1
chmod +x M101
exit 0

I also have this in the .ini file.  But I understand how its unnecessary so maybe I'll remove it:
setp hm2_7i96s.0.ssr.00.out-00 false

This is now working to turn the pumps on and I have a code similar to M101 called M102 that turns them off. 

The base of all this code came form chatgpt.  Chatgpt can do porgraming in C pretty well from what I've seen. But it struggles on LinuxCNC obviously, gave me a bunch of unnecessary stuff.  


So I am going to get some of the other things that need similar control working, work on the post processor and get the buck converter set up.  This might take few days as I am celebrating Christmas tomorrow.  

In the meantime, does anyone have any idea how I should program the PID loop based on the PWM signal? Has anyone written a program like this in LinuxCNC before?  I can get the M52 Pn command into my post processor but I dont have a clue how to do the PID loop right now. I am wondering if it needs to be written in the .ini file, should it be a script thats written in python and placed somewhere else, or...?

Thank you and best,
-Dylan

Richtig Tchefter.
Beim ersten Start von LinuxCNC konnte man auswählen was für eine Maschine man hat. Hier hab ich Sim- Axis-mm gewählt.

Und ja, MaHa.
Die Werte werde ich von der realen Maschine versuchen zu übernehmen. Hab dann auch meinen Fräsraum.
Nur habe ich ja in der Simulation keine echten Endschalter. Die wollte ich in der Simulation  übergehen. Wie man dann eine Simulierte Referenzfahrt macht weis ich nicht.
Es ist richtig, das bei Start der Simulation wo der LINUXCNC Schriftzug eingelesen wird eine Referenzfahrt gemacht werden kann.
Wie auch immer die Macher das defaultmäßig eingerichtet haben weiß ich nicht. Danach kann ich mein eigenes Programm laden und ausführen. Wenn ich aber die Maschine stoppe und wieder mein eigenes Programm lade, muss ich eine neue Referenzfahrt mach. Geht aber nicht und der erwähnte Fehler kommt.
Einzig LinuCNC beenden und neu starten der Schriftzug kommt wieder und ich kann eine Referenzfahrt ausführen. Ist zwar nervig aber eine Notlösung.

MfG.
 

The RK3588 is based on the ARMv8.2-A architecture and uses a 64-bit ARM (AArch64) core.

There are ready made debs for ARMHF architecture here
buildbot.linuxcnc.org/dists/buster/maste...reempt/binary-armhf/
What architecture is RK3588 listed as?

My development board uses an RK3588 motherboard

I need to port Linuxcnc to an arm system, and then I need Buildroot to build and compile linuxcnc

Yeah, it is. I told them we were too far apart to make it work at the moment, but some of the older stuff still said linuxcnc.The other part was, it uses onboard TMC2160 drivers with SPI config, but it includes headers to use external drivers. They said something about their software engineers but they didnt reach out to me further. They included an SPI + UART connector for us, and we can use the Wifi connector as well with my w5500 adapter.
I can send you one if you want, but its basically an SKR3 mixed with a flexihal. So aside from the TMC drivers it should probably work with some minor tweaks.

setp hm2_7i96s.0.ssr.00.out-00 true

Doesn't make much sense here as the output is controlled by
edm-pump-output

 

Hi all, thanks for the help trying to solve my compile issues, in the end I used the docker method, definitely recommend this for people like myself, not too bright but can lift heavy things

did you edit the ui?
