PoKeys / Pokey 56U with two mpg

« on: November 29, 2012, 12:49:34 PM »

I have rebuild a Lathe to Mach3, the stepper drives of the machine are controlled through a parallel port interface.
The machine has also a pokey 56u and a kdb48CBC keyboard. The machine has also two encoder which I want to use as mpg for
the x and the z aches. The encoders are connected to pin 18,19 and 20,21 (so encoder 4 and 5).
Pokeys config software and mach3 plugin from 25-11-2012 is installed.
In the plugin settings the encoder 4 is connected to DRO 101 and encoder 5 to DRO 103.
The values in the DRO 101 is correctly responding to the first encoder MPG 1 (x) and DRO 103 to the second MPG encoder (z).

The problem now is that when the X is selected on the keyboard (MPG jogging) then the X axis is responding on the first encoder (MPG) but the
X axis is still moving also when the encoder (MPG) is not changing its value. When I press stop (end jogging) then the axis stops but when I restart jogging
the X axis starts moving.
What I notice is that the value in DRO 101 is switching between 0 and the encoder value every few seconds, so it seems that something else is also
writing to the same DRO 101 !
Is this the reason that the X axis is constantly moving ?

Am I doing something wrong ? Or have is missed a setting somewhere ?

Thanks in advance.
