I hope someone can help with this....

I have a sensor next to my spindle and the signal is connected to a Polkeys57E. The pin is configured as the Index input. I can see the signal pulsing in Pokeys when the spindle is running. However the spindle speed always shows 0 in mach3. So somehow the link for that particular signal is being ignored. I have many other signals that are being passed back and forth between Mach3 and PoBlocks and they are all working just fine.

I have tried issuing the M03 command, no difference, and in Mach3 config, the index signal is set 0, 0, 0 and emulated, and reverts back emulated even if I uncheck it, so it appears Pokeys is forcing it to emulated likely because it's smart enough to know that this value is linked to the 57E

Any ideas?

What is the correct DRO # for the displayed spindle speed?

Thanks in advance

General Mach Discussion / No Feed Ovrd when using MDI
« on: April 18, 2018, 05:54:37 PM »
I'm just flushing out the last of the bugs in my custom control panel and found this one........

I have a quadrature encoder connected to a Pokeys 57E, this is configured as MPG0. I have a brain that redirects the output to Feed Ovrd (821)

This seems to work just fine when Mach is not moving anything, however if I enter say G01 X5 F2 into the MDI  so the table is moving and I then try to tweak the feedrate using the encoder, no change. Further if I open the brain the MP0 Velocity DRO displays 0 while I'm moving the encoder as if MPG0 is either locked out or being ignored while the G01 command is executing. As soon as the table stops the barin starts showing activity again and I can adjust as desired.

Using the GUI I can adjust the feed rate up and down with the +/- arrows above FRO, but attempting to enter a new FRO value from the keyboard is ignored.  

Is there possibly a configuration selection that enables/disables changing the FRO while in motion?

Machscreen Screen Designer / Custom button, Hotkey not working
« on: April 17, 2018, 02:07:42 PM »
Newbie to screen modifications......

Please see image below

I added a button JTO Ctrl-B and a LED.

If I click on the button using the mouse, the LED besides it turns green, so far so good. However if I Type Ctrl-B, the button does not get selected. What am I doing wrong?

General Mach Discussion / Keygrabber ---> Brain
« on: April 16, 2018, 07:52:38 AM »
Is it possible to use KeyGrabber to trigger the first column of a brain?

I have no experience with KeyGrabber other than starting the application and  poking around a bit. In the translate column, I can select another key or choose a special key, not sure if the special key can trigger a brain?

Brains Development / Jog (Tab) display status
« on: April 15, 2018, 02:07:00 PM »
I have a brain that displays the jog tab, when ever I push a jog related button on my pendant. Unfortunately the display sometimes gets out of sync with the brain. How can I inform the brain of the present status of the jog (tab) display?

I have been testing the demo version of Mach3 Mill, mostly positive so far. When I monitor the charge pump signal, every second or so it drops a pulse, reducing the frequency to 6.25kHz for one cycle. This plays havoc with my watch-dog hardware that is looking for a 9-15kHz signal.

I'm presently running the kernel at 25kHz because of the demo version limitation. If I purchase a license and then increase the kernel speed, will the dropped CP pulses be fixed?

General Mach Discussion / Motors intermittently shudder whie in reset
« on: April 09, 2018, 01:28:03 PM »
I'm at a loss as to why this is happening.

With the Mach3 Reset button pressed (solid green) i.e. not in reset or emergency mode, the steppers are silent unless I command them to move, everything normal and as it should be.

However if i press the Mach3 Reset button (flashing green/red), the steppers intermittently shudder, when I say shudder, they don't actually move, however I can hear the coils being de-energized/energized momentarily, and I hear a slight ping from the motors. If I place my hand on the motor I can feel it, perhaps every second or two.

I scoped the direction and step signals at the parallel port and I don't see anything that looks like it could trigger the drive. Even with the scope set to single trigger mode and a threshold of about 1 volt. When in run mode with the steppers moving, nice clean 5V square waves, so the scope and triggering are working.

Unless there is an actual E-Stop (not a press of the reset button on the Mach screen), the enable signal to the drives is active.

Anyone experience something like this?

Some time ago I had a bunch of brains working with mach3. At the time I was using a Pokeys57E with shared data etc.

For the moment I have all those old brains disabled, and I'm simply trying to run one very simple brain....

Output 1    NOP    Delay    Output 1

The moment I click on the enable checkbox for this brain, Mach3 crashes with an Artcode 9991 error.

I tried uninstalling Mach and then reinstalling, the Pokeys57E add-on is presently NOT enabled. I have no idea what's causing the crash?

How do I activate an output a few seconds after Mach starts, and then stay on for the duration of the session?  I prefer to use a brain, and know how to add the delay before driving the output, I just don't know what to use for the first box in the brain?

I don't want to waste and input.


PoKeys / Can't get motion Control Hardware Plugin sensed dialog to appear
« on: January 02, 2018, 03:06:48 PM »
I recently added a Pokeys 57E to provide addition I/O capability to my Mach3 setup. I now want to try using the Pokeys stepper driver signals. Try as I might I can't get the Motion Control Hardware Plugin sensed" dialog to appear, so I can select the Pokeys motion control.

I have tried the following:

1) Selecting Function Cfgs|Reset Device selection....... this invokes a message box stating that "You will be asked on next startup what device to use...", however on subsequent startups, the dialog does not appear.
2) I tried deleting PoKeysmachConfig.xml.......same result
3) Completely uninstalled Mach3 as well as Pokeys, deleted all the registry entries and then reinstalled ..... same result
4) Tried using an older version of the Pokeys mach.dll.....same result

Anyone encounter this?
