Subject: How to test Kanalog

Hi all,

I've had my Kanalog + KFlop since July last year. I was never able to get the Kanalog functional, and as such gave up on using it and the KFlop, and got a smoothstepper to sate me in the mean time.

However, now that I have some time I've been playing with the two. I have been using the KFlop with two breakout boards to get step+dir (which works very well). I would like to use my Kanalog, but I have still not succeeded in getting it working - that is, any input or output from the board.

Is there a way to test whether my Kanalog is functional? some visual indication that it is operable? I would love to use it...

Any help is appreciated.

Thanks,

Lindsay

Presuming that you have KFLOP JP7 connected to KAnalog JP14 then there should be an LED lit by JP12 pin 1 on the Kanalog.

Then in the KMotion app you should be able to enable the KAnalog board in the options menu. When you have done this you can access the Analog Status and you should see some floating voltages reported. Also the digital IO Kanalog page.

I do have JP3 connected on the KFlop (I have both USB and other PSU connected, the PSU makes no difference AFIK if there is nothing drawing power)..

Hope that helps.

Thanks Jon,

Yes I have KAnalog connected to the KFlop via JP14 and JP7 respectively.

The LED on the Kanalog is NOT lit however.

I have the KAnalog enabled on the options menu, and I do see floating voltages present on the analog status window. Removing the IDC ribbon connecter between the two causes the voltage to go to -10v - so this is a good start. Also, upon inserting said ribbon connector the LED on the KAnalog illuminates for a fraction of a second.

I have tested this with the USB +5v jumper inserted and removed.

Also, grounding out any of the ADC pins should definitely cause the read voltage to be 0, correct?

It may be some sort of configuration error... who knows.

Again, any help is appreciated.

Thanks,

Lindsay

Problem solved! (partially).

Loading a recovery flash solved one of the problems. The KAnalog now has an illuminated LED.

However, grounding the ADC's as a test results in no change in the read voltage.

Is this normal? Am I missing something fundamental?

Thank you.

Hi Lindsay,

The screw on the top of the terminal often does not make contact with the pin unless the screw is tightened. Are you aware of this?

You might also try to change a DAC voltage with the Console Screen: DAC0=1000. Try it just after cycling power so everything is in the default configuration and no axes are enabled.

Regards
