Mach3 Pendant
« on: March 07, 2018, 09:30:43 AM »
Hello everyone,

Some time ago I installed a LPT2 card and a pendant in Mach3. The Usual stuff. All seemed to work fine.
Then I found out that some times (if not often) the wrong axis is moving when turning the MPG.
Using the Diagnostics window in Mach3, I found out that the pin status is correct and matches the setting of the X,Y,Z pendant knob.
I tried debouncing the X,Y,Z  LPT2 input contacts, but to no avail.
Has anyone any idea what causes this phenomenon and how I can solve it ?
Regards,

Hi,
what pendant is it? Do you have a manual?

I have a VistaCNC unit and it is connected via USB to the PC and so doesn't require a parallel port at all.

Helo Craig,

I have a "Propendant", which is the most ordinary pendent you can imagine.  Just the case, the switches and the wires. It is to be connected to the LPT2.
It works OK most of the time, but sometimes the internal Mach3 settings for which axis is to be controlled, get out of phase with the settings of the axis knob on the pendant.
The pendant itself seems OK, as can be seen from the diagnostic screen.
I know there are many other pendants available, but like to know what is going wrong here.
Best regards

Wilfried.

Hi,
do you have a manual? A circuit diagram? A picture? Anything?

Hello Graig,

I fear you are thinking along the wrong track. The hardware of the pendant is OK.
That is proven by the fact that the diagnostic Window of Mach3 shows the correct LED's lighting up when the axis-knob is turned.
The problem obvious is the handling of these settings within the "brains" of Mach3. There the internal variable representing the axis to move gets out of sync with the input status of the relevant oem#  pin.
Best regards,

BTW: The relevant part of the ProPendant consists of a 5 way rotary switch. In each of the positions 2 to 5, the relevant contact is connected to common (0V).
In Mac3 the oem#1,2,3,4  Pins are set to "Enabled" and "Active low". That's all.

would be helpful if you post your brain/script witch controls the axis selction.
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

Hello,

This is the simple brain I use to control the X-axis.
Hope this helps.
Best regards

Wilfried.

Centroid Wireless MPG for Acorn CNC Control System CWP-4

Will this pendant Work with Mach3?
