7i76e: MPG and Analog inputs with pncconf?

if i select this mode 2 pncconf crashes when i try to safe and quit:

I tried this in the latest version of pncconf in the 2.7 branch - what version of linuxcnc are you using?
it has to do with the selection of external MPG, on the external controls page. What option did you select and what di you select for the MPG encoder in the mesa page?

i'm using the latest master 2.8xxx
i tryed different options in the external controls page. if i set the mode 2 in the I/O connector 1will crash if i try to finish the pnccconf.


i get 3 potentiometers running. i found some code from a 2.7 installation. the first 3 blocks are running after smal changes.
but for the jog speed this looks different. can someone help me with the fourth block of code? the one vor the jog speed.

This assumes that you use 1 MPG for all axes and you use a binary coded selection switch so you only use two inputs to set 4 sale settings one of them is 0 or OFF. The order of the mux4.in's is dependent on my hardware but it is a metric machine so in mm.

For completeness, I will add my axis selct code here. Normally you would use another mux4 component but in my case I have a 6 axis selection knob on my pendant so I've used a mux8 paired with a select8. This lets me add another 3 controls. eg. I could use the Axis 4 selection setting to control reverse run to step back and forth in the g code. (maybe....).

Also note you need to convert the data type to keep select8 happy.

Hope I've copied accross everything you need....

I confirmed the error in pncconf and just pushed a fix - it will take a bit of time for it to cycle through - unless you are compiling source code.
Thanks for the information.

@cmorley: Tnx! I'll try it tomorrow.

@rodw: tnx for the code. i use two mpg and 4 potentiometers and a joystick with 4 tact switches.

at the moment im searching for a solution to connect the potentiometer to the jog speed.

this is my control panel:
