Slow optocouplers.
Better quality BOB should help, or just get 2 fast optos.

My lathe spindle originally had an Index pulse and 10 encoder pulses per revolution. From the problems discussed in
      forum.linuxcnc.org/38-general-linuxcnc-q...peed?start=40#319800
I thought it would be better if I generated more than 10 pulses per spindle revolution.

I built a ring to fit on my lathe pulley with 180 teeth. I picked this size because it had the most teeth that I though I could machine. They were about 1/16" width and depth. I found that the proximity probe I was using could not detect these small teeth. I replaced it with a Hall Effect Sensor =11.0ptS38J-22ADSO-5KJA5 from Standex Electronics. Here's the installation:
 

Here's what the output looks like at 400 RPM on my oscilloscope:
 

This is about 24V. The frequency of the signal is about 6 cycles in 5 mS, or 1,200 Hz. Expected signal is 180 pulses * 400 RPM / 60  = 1,200 Hz. So far, so good.

The signal goes into a breakout board with optoisolators. I can see the signal on the input and output side of the optos, so I know it's going into the circuit OK. I don't see any missed pulses on the oscilloscope. The breakout board feeds a Mesa 7i92.

When I pull up the encoder inputs in HalScope, I see:
 

Not good. I should see 180 pulses between the index pulses. I'm seeing about 10. Plus, one of the index pulses is missing.

I have a separate DRO that also displays the spindle RPM. If I compare it to the RPM shown on LinuxCNC, they match from 0-150 RPM, then for higher speeds LinuxCNC shows speeds lower than 150.  So if the lathe is at 500 RPM on the DRO, LinuxCNC shows about 60 RPM. Again, I can see on the oscilloscope that I'm getting all the pulses.

Here is my .INI and .HAL files. Any ideas?
 

isn't 'cia402.n.controlword' an output pin? (you can't setp output pins)

Hahaha
I used to get the "I'm a hacker and have hacked all your devices and have videos of you watching rude videos and doing rude things"
My reply was "all still images and videos of myself are copyrighted. I will have my people visit you to discuss your upcoming self deletion. As we are reasonable people we will not expose your friends and family members to the videos you have collected of random people doing things"

These always came to an old Hotmail account I've had pre 2000, and look at every 2 months or so.
Seriously, I've seen every scam known to man come through that.

That would have been how to ask for what you wanted. Concise and to the point.
Maybe someone on a Mac forum or similar could provide one, tho I would ask for a Debian bookworm image, as asking for a Linuxcnc image might lead to answers you don't want.

Is it still possible to import VirtualBox virtual machines into Parallels ? And is it possible to import an x86 VirtualBox VM into Parallels running on an Arm based Mac.
Or step over to the dark side and obtain a 2nd hand T series Lenovo laptop. T530 work quite well. Easier to transport from your workshop, office, ivory tower or wherever.

  I am well on my way to that myself. Between this and the Bambu Lab scenario I am waiting for Dr.Evil to emerge from the shadows
with some sort of ransom deal. LOL

Hi Grotius.

Really cool! Tomorrow I will have some time to test around. I also wrote a small ncode with some loops to test P and F values. Will test and provide tomorrow.

The conversion I dont get right now. Of course I know how to use components and so on, but have to look how you mean it.

Julian, can you join the qtpyvcp chat room?

Obtain a Parallels VM of LinuxCNC created on an Intel Mac.

Hallo, liebe Linuxcnc-Freunde!
Ich habe dieses Handrad WHB04B-4 auf meiner kleinen Maschine installiert. Es funktioniert einwandfrei. Nun habe ich mir eine 2. größeree CNC Fräse gebaut, auf Linuxcnc neu eingerichtet. Durch Umstecken der Achsen ist natürlich immer nur eine in Betrieb.
Auch das Handrad habe ich auf der neuen Maschine eingebunden (die Handrad-hal- Datei habe ich in die neue übernommen.

Jetzt kommt das Problem: die Tasten auf dem Handrad funktionieren, am Display erscheint fix RESET: das Handrad selber reagiert leider nicht. Die RESET Meldung ist nicht wegzubringen, auch dann wenn ich die Schalter Contnuos und Step verändere.
Für mich ist unverständlich, warum dasselbe Handrad mit den gleichen Einstellungen in der Handrad-Hal auf der einen Maschine funktioniert und auf der andern nicht. Was kann ich tun, damit das Handrad auch auf der größeren Maschine ordnungsgemäß funktioniert.
Danke!
Beste Grüße

Hi Julian,

Did some updates.

The scurve is now conversed to c code. I think this is easyer for bug solving.
And it can now be used directly in lcnc components.

I forgot to apply the feed overide to the end velocity's of segments.
Now it's running much faster.

I came accross a new bug. When a new buffer was loaded, the velocity was starting from zero when
using feed overides around 300%. Lower than that the bug was not visible.
This now is solved. During a new buffer load and transition the velocity keeps up.

There was also a endvel=0 error, wich halted motion,  is solved by pushing the motion into a new segment,
depending on rundir.

Extreme feed overides:

Hello everyone,I'm currently facing an issue while trying to write to the pinusing thecommand in my configuration. Despite the documentation indicating that this pin should be set to read-write by default, I am receiving the error message:"pin 'cia402.4.controlword' is not writable."Here are some details about my setup:

• I have verified the HAL configuration and ensured that the pin is defined correctly.
• The EtherCAT configuration appears to be set up properly, with the relevant PDO and SDO entries.
• The drive is in a state that should allow writing to the control word.

I would appreciate any insights or suggestions on how to resolve this issue. Has anyone else encountered a similar problem? Any help would be greatly appreciated!Thank you!

Thanks for the input guys. I have been able to get quite a bit of the interface working, (display alarm/state, query status of all components, get firmware revisions, set source, set process, and fire torch), but there is still a healthy chunk more to test and work out.  Unfortunately, the XPR I have been connected to has to ship out in a few days and I just came down with the flu.  I have written a python script / hal component to upload and download sdos with a back door local network socket connection to do large multi-index updates and to set things from the gui.  It seems to be working adequately, but still needs a few tweaks and more testing to make sure it is robust.

TRUE HOLE

Hypertherm has a list of features a cnc has to be capable of in order to claim it can support 'True Hole'.  The biggest hurdle is that given an ending feedrate for an arc segment around a hole, it has to be able to ramp up velocity, (the feedrate), linearly from the beginning of the arc segment to the end of the arc segment.  I don't think we have that ability with linuxcnc.

Well it's official January 2026 Autodesk Fusion 360 will no longer support Windows 10 . Either switch

Windows.... has been a train wreck for anyone who remotely values their privacy and/or security.
 

Hence the last version of Windows I used was Vista. Linux all the way for me.

Vielleicht hängt das mit diesem veränderten Verhalten zusammen:
