Guys, try the attached.  No idea if it works, but it's not giving any errors and outputs data.

I do know about the pot on the PSUs but wasn't sure dialing it down 2volts was a great long-term choice. Dropping in a few diodes makes sense, I'm guessing the current draw on a VFD control would be minimal. I should have a bunch of 1n4001 laying around here somewhere lol.

Thanks

For no real good reason I'd like to change my lathe from using 0-5v to control the spindle to 0-10v.
The VFD is an old VFD05-D230 and it has the options of 0-5V, 0-10V and 4-20mA and supplies it's own 5v if you are using a potentiometer so it looks like I just wired my 7i76 (old version connected to a 6i25 via DB25 cable) in place of the pot. I can't find any way that VFD will supply 10vdc so I need to use an external power supply but most are 5 or 12 (when I say most I mean all the ones I have here and the quick look at meanwell online. Digikey ones quickly jump to well over $100)
I know 0-10 is closer to standard but what are you using for supplies? Is a 12-10 buck converter ok? Can I "turn down" a meanwell 12v to 10 without killing it?
Just asking what some options are
Thanks
 

So wie ich das lese, willst du den Motor als Spindel einsetzen....
Wenn ich all deine Wünsche berücksichtige, landest du bei Kollmorgen. Das sprengt aber dein Budget

If the toolchanger robot only requires point-to-point motion and doesn't require circular or linear interpolation, then extrajoints can be used. Basic safety chains, homing, and limits will work as for other regular joints. However, for motion planning, you need to connect the simple_tp or limit3 components. Their motion calls should be implemented in custom M-code (e.g., M100 P1.2 Q23 ...).

oooh. yeah we can 100% just have single axis at a time motion for this.
thanks, ill look into this.

The devices is starting to take shape here

 
 

As a bit of background on the chuck/no-go safety model:At work I requested a machine with a control that includes an integrated safety zone around the chuck (something I had seen on Heidenhain controls).
In the end, I was assigned a lathe with a Siemens control, and I’ve been very satisfied with it — it works well in practice and I can program effectively on it.However, the concept of having the chuck geometry considered in the motion/safety logic stayed in the back of my mind.
Since that idea seemed useful for safe at-the-machine programming, it eventually found its way into LatheEasyStep’s design.

Hi all,
here is a short update on the latest changes in LatheEasyStep:

Step list loading issue fixed
In some embedded QtVCP scenarios, the operation list stayed empty after loading a single step or a full program. The operation list binding is now more robust.

Safer retract/free-travel logic (lathe-specific)
Retracts are now context-aware per operation:

simultaneous X/Z where safe
groove/keyway: retract X out of material first, then Z
drilling/threading: retract Z clear first, then X
Current tool position relative to stock/chuck is now considered.
Extended chuck / no-go safety model
The program header now supports chuck-related parameters (size, workpiece type, clamping mode, profile) with automatic no-go zone calculation.

New machine/workshop profiles
Quick presets apply typical parameter combinations automatically (e.g. chuck + clamping mode + profile).

Preview improvements
The chuck safety area is now shown in the preview as a dedicated colored zone, including a legend entry.

Save/load extended
New header fields (chuck/profile/no-go/machine profile) are now properly persisted and restored.

My C enable was commented out by accident

Hi,

Now that we won't be getting any support from the German PLC forum, I did some searching myself and found this interesting project. In my opinion, it could serve as a good template, as all the code I've seen so far uses a similar topology.

I would also like to emphasize that there is no need to reinvent the whole concept. We already have functioning components (CIA402; homecomp.comp) that form a good basis. Many thanks to @rodw and @MobiusToast for their excellent pioneering work. What is missing now is the further development of these components.
I fear that even this thread, with its good approach, will ultimately be forgotten.

For my part, I will take a different path.
Since I continue to have homing problems and have now ruled out EMC and configuration errors, I think the problem lies with the A6 itself. Yesterday, it took 3 minutes for the x-axis to start the reference run! 
I will now try to expand my system to include battery-buffered encoders.
At least according to the documentation, this should be possible. This would make homing obsolete.

 

Hallo Linuxcnc Freunde,

habe festgestellt das bei dem Handrad XHC-WHB04b-6 die Lead Funktion nicht richtig funktioniert.
Habe an der Treiberdatei pendant.cc die Zeile 346 hinzugefügt. Die "oder" Funktion für die 9b oder 1c wurde ja schon mit einegbaut. Danke an alle dafür.

Bei mir funktioniert diese jetzt und lässt sich aktivieren.
Hoffe konnte ein bisschen weiter helfen. Leider muss dazu Linuxcnc neu erstellt werden mit dem make Befehl.

Habe versucht die Datei mit hoch zu laden, hat aber nicht funktioniert.

[edit]
 

Thanks a lot. I was afraid to hear this but at least I know where I stand now.
