Got it! Now that I had RPM control forward and reverse with a bonus green GUI scale in both directions it was just a matter of adjusting this:

setp scale.0.gain 0.00275

To this:

setp scale.0.gain 0.008

Which so far is the closest to s300 command. I'll know more when I get an RPM gauge on it.

It may require some adjustments in the VFD. But I'm content with the progress so far.

I think I'll have to go back a couple of steps and try to fix my probe basic config before I continue work on this.

I seem to be having the same trouble as this other user...

forum.linuxcnc.org/qtpyvcp/56674-probe-b...-parameter-variables

I was able to get basic probing routines working by manually editing the parameters in the var file. However, the link between values entered in the ui boxes and the var file seems to be broken. If you try to change a value by entering it in a box it just doesn't do anything.

Is there a place where all the necessary configuration steps are a set out clearly?

I was trying to follow these but evidently they are not totally clear and a bit lacking:

kcjengr.github.io/probe_basic/index.html

I think my config got messed up a couple of times, e.g. by copying values for an imperial machine into my metric machine's setup. The parts that need editing could be made a bit clearer.

Good point tommylight Though I may modify the models for CNC machining .

I have a small HP ProDesk 400 G3 SFF. From your suggestion i have looked at both devices (same pc type) bios settings, as of now nothing sticks out yet.

One step forward. After some digging on the internet I went into custom_postgui.hal and changed this:

net spindle-vel-cmd-rpm gmoccapy.spindle_feedback_bar

To this:

net spindle-vel-cmd-rpm-abs gmoccapy.spindle_feedback_bar

And it now shows a green status bar in the GUI in forward and reverse.
Still working on the rpm issue.

I had a couple of Mesa cards laying around for years and finally found some time to put it into operation.
Especially because the RPi5 comes with this massive performance boost <3
It’s all basically working, except for the pinout (had to solder an adapter), and everything seems to work in auto or MDI mode,
although I only tested a few moves; but manual control is extremely choppy.

The constant movement is just interrupted, as I would have stopped pushing the the button.
Acceleration/deceleration is working, so it’s not a communication issue.

Here: 


Probably unrelated, but strange:

At the end of rapid moves, controlled via MDI, the controller or LinuxCNC creates some extra steps.
I did not count them yet, but will check this after the rest is okay:

 


Are these “user space” issues? Currently I exclusively have older RTAI setups working;
never used this one kernel thingy.

Did I set up anything incorrectly?


thx

You are correct, Peter. When pncconf generates the configuration HAL file it include two lines that prevent LCNC from launching. A search on the forum identified the culprits and suggested the two lines be commented out. In my zeal to get on with my project, I commented out the wrong lines. Correcting the issue resolved the problems.

Kind Regards -

 

Hallo zusammen,ich stehe am Anfang eines Projekts ähnlich dem von Rüdiger und möchte meine gebrauchten Rexroth IndraDrive HSC01 in LinuxCNC über EtherCAT betreiben. Aktuell sind die Antriebe jedoch mit PROFINET-Firmware ausgestattet, weshalb ich dringend die korrekte EtherCAT-Firmware benötige.Folgende Eckdaten zu meinen Regler:

• Typ: HSC01 E1 W0003 A02 B ET EC PB L3 NN FW
• Aktuelle Firmware: FWA INDRV MPB 20V28 D5 1 NNN NN

Meine Fragen an euch:

• Ist R911330278  "FWS INDRV MP* **VRS NN ETHERCAT" tatsächlich die passende EtherCAT-Firmware für diese HSC01-Variante?
   

Rexroth selbst hilft mir nach  Nachfragen nicht weiter. Ich freue mich über jede Bestätigung, Quelle oder Hinweise zum Vorgehen!Vielen Dank im Voraus für eure Unterstützung.Viele Grüße Thomas

Hi, yes that is possible. I would actually reccommend the esp32 over the Arduino, as if I remember correctly the ADC resolution is better on the ESP.
I only ever used it with USB interface.
If you know what you are doing I guess you can run it in ttl2USB too.

Memory at d1000000 (32-bit, non-prefetchable) [disabled] [size=64K]

is suspicious, Sometimes this is BIOS option related.

Not entirely sure if this is the correct category of the forum for this question, but here goes:I've just done a completely fresh install of LinuxCNC and I'm running into a few issues — some related to EtherCAT, but also with.I'm trying to usewith a 5i25 board. I installed it and ran the following command:But I get this error:The 5i25 itself isn't broken — I’ve tested it on another PC and it works fine.When I run, I can see the board:It feels like something went wrong during the software installation. Has anyone seen this before or know what might be wrong?

As Tommy said, it's difficult to say without seeing all of your settings and such.  The sputtering is likely a connection issue of some sort, but the dive looked to me like there's something set incorrectly.  Looked like a move to cut height that was in the part rather than above the part.

Alright. I went from:

P = 2
I = 2
D =0
FF0 = 1
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 1
MAX_OUTPUT = 3000
ENCODER_SCALE = 4096

to

P = 0
I = 0
D = 0
FF0 = 1.0
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 1
MAX_OUTPUT = 3000
ENCODER_SCALE 4096

By just changing the ini I now have same forward and reverse spindle control.
However two things are different. The speed is a fraction of what is being commanded, S300, it's closer to S25 and it doesn't show a scale on the GUI in reverse, a minor issue I can address later.

I'm not sure what to # and where to add:

"PID command = signed commanded spindle speed in RPM
PID feedback = encoder RPM
PID output --> ABS --> analog out
ABS sign (of PID output) determines the FWD/REV pins"

This is definitely a step in the right direction.

I'm going to go ahead and try this. I'll let you know what it does.
The one thing I'm having a hard time wrapping my head around is even with analog control, I have speed control forward. The GUI bar turns green and moves goes up and down with the override buttons, just not in reverse. In reverse goes to a set number, a number I cannot find and stays put regardless of what's pressed. However, if I reverse the forward and reverse signals to the VFD I have the same forward control as before, now in reverse. I don't see why the same forward and reverse control shouldn't be possible,

If it's necessary to convert this to PWM to gain the same forward control as reverse, so be it, this Mitsubishi VFD is capable.
I'll cross that bridge when I reach it.
I need to gain a better understanding of Linuxcnc spindle control.
I appreciate your help.

Change pierce delay to something much smaller, like 0.2 for up to 5mm thick, 0 for up to 2mm and 0.5 for 5-10mm, etc.
Also show us other settings and the main screen while cutting.
