Maybe pass the position-command through a limit3 HAL component to limit velocity and acceleration?

The VFD on my high-speed spindle feels a bit like this, it starts sluggishly then seems to nearly get stuck, but in my case it then accelerates away to commanded speed.

Make sure that you really are getting 10V (or whatever) on the analogue voltage input to the VFD using a multimeter. (Also check the polarity...)

You could try operating the VFD with a potentiometer in the conventional way to check if the behaviour is the same.

I was wondering if a conformal coating would help, and found this thread, which may have some relevant ideas:

If you are using CSS then this might be more complicated than it first seems.
The PP would need to calculate the spindle speed at the start and end of the sequence of feed moves and choose a spindle gear appropriately.

My own lathe handles this in HAL, but certainly not optimally. It will often do a gear change at the end of a facing cut, then change back at the start of the next cut, which isn't ideal.

Rather than preventing motion altogether, you could simply put a message on the screen when the probe fault output is set, using the "message" HAL component.

That said, how much of an issue is it if the toolsetter is disabled when the probe has a fault?

If the probe has a specific tool number, you could potentially add that to your logic.

Is the "3D plotter" specific to ProbeBasic?
If so, you might get better answers on the ProbeBasic part of the forum.

If "call" is the "unknown word beginning with "C"" then I think that this must be a ProbeBasic thing, as I have never seen the other UIs (which mainly share a previewer) have a problem with subroutine calls.

I am not entirely clear what problem you are seeing, but you should just be able to set the F-ERROR limits for the X axis very high, and then no errors will be raised.
If the problem isn't following-error trips, then I think we need more info.

Thank you Erick, i just talked to them and everything is OK, the left side angled not unloading is a safety feature as i thought, so the idea of leaving a straight cut in front of it with small tabs worked like a charm.
And we do have a pallet of manuals, mostly in Italian language and mostly not exactly for this machine as the pictures show the old version of the software, but still they did help a lot initially.
Again, thank you very much, i do appreciate the offer.

Main menu > preferences > appearance , chose a white theme, close and start LinuxCNC.
On my monitor i can see and read everything easily, but on most VA or TN monitors it might be very hard to read.
Try setting the brightness and contrast on the monitor, see if that improves things.

Moin,

ich habe ein ziemlich triviales Problem: Wenn ich "halshow" (und div. andere Programme) aufrufe, kann man fast nichts erkennen, weil die Farben alle extrem dunkel sind  (s.u.). Ich finde nicht heraus, wie man das ändern kann. An dem verwendeten Theme liegt es anscheinend nicht! Kann mir jemand einen Tipp geben, wo man da hin greifen muss?

 

Vielen Dank im Vorraus
Chris

hallo michael,

Yes I have made the following connections

22 - SPINDLE- to COM
23 - SPINDLE OUT to AI1
24 - SPINDLE+ to +10v
and
S1 --> OUT4A
OUT4B --> COM

S2 --> OUT5A
OUT5B --> COM

So with this done, I set Spindle PWM as in the below picture but the spindle doesn't move when I run the config and try the + and - buttons for the spindle. Any ideas would be greatly appreciated. Thanks

Hi PCW, thanks so much for that but the option isn't there on my menu as you can see below. Is there some package I need to install for this?

Hi all,I’m in the process of retrofitting a Busellato JET 2 CNC machine. The machine has one main spindle, a side spindle, and drills, but I only need to control the main spindle.The spindle is still running on the original VFD, which has not been altered or replaced.Originally, the VFD was controlled via serial communication, but since I’m using a Mesa 7i77 card, I converted it to 0–10 V analog control (the serial setup seemed unnecessarily complex and hard to understand).Here’s what I’ve tried so far:

• Using the original VFD (unchanged).
  • Converted VFD control from serial → 0–10 V (Mesa 7i77).
    • Adjusted VFD parameters to allow external analog speed control.
      • Able to start the spindle successfully.
        • Spindle ramps up but only reaches ~50 Hz.
          • After about 10 seconds at 50 Hz, the VFD trips into overload.
            
            My observations:
            • It sounds like the spindle wants to accelerate further but is somehow being held back.
              • I’ve spent several hours tweaking and checking parameters, but I can’t figure out where it’s going wrong.
                
                Any tips, suggestions, or guidance on how to properly configure the VFD (or what to check mechanically/electrically) would be hugely appreciated.Thanks in advance!
