How many DDCSV external buttons ?

Good to hear that its stable. Will have a go at installing it.

My feeling from playing about with the DDCSV is that the buttons on the panel are awkward and relatively frail. For instance, jut to use the pendant means two button pushes to select mpg, then another two to go back to run mode. 4 presses for a minor adjustment seems a lot to me, and I cannot see that type of button putting up with that sort of use for long. Likely membrane will split or switch will fracture its solder connections due to mechanical stress.

This is why I thought I would duplicate the most used buttons (mode, tab, shift) for tactile robust ones. As you pointed out, start, pause and estop can use external buttons straight from the back panel. So I make it 6 buttons + the usb skt  for my panel layout so far.

FWIW I reckon the pendant will use 12 core cable :-(. Its sort of on the cusp as to whether its worth doing some electrickery to use 3 core cable or wifi/infra red/bluetooth for cable less control. Could even export the mode switch (and others) to the pendant doing it this way which is much nicer. I seem to remember in one of the threads that the keyboard driver was still in situ, but I don't know enough about it as yet.

The pendant should come with a coiled cable.  You need to watch that you use a pretty fine strand cable if you extend it.
I would hard wire it, rather than adding a layer of uncertainty.
I guess you are thinking of cracking the case to get at the keypad lines?
You might try plugging in a usb keyboard after flashing pandora and see if that can do some keypad functions.

That was exactly what I was going to try. Very easy to do although what will transpire will be very uncertain. If it does work with keycodes that will make life much easier.

Just have the switch on order for the pendant, though I have a supplier of cable if I go the hardwire route. 12 connections + any other other keys I want on the pendant is a lot of wiring. Also not having a cable seems like a good idea, but I suspect I will lose the pendant if its not attached  :palm:.

" I used to be undecided but now I'm just not sure " :scratch:

Too much to do today for pandora, but will give it a try tomorrow. Latest Version Pandora-20180106.

Hi
The upgrade to pandora was a bit heart stopping. After inserting the flash drive and allowing a little time for the install the madmodder flash screen came up and then about 2 seconds later disappeared leaving a screen with light gray and white vertical lines. I then waited for about 10 mins in case it was going to do something else, but in the end I took the plunge and turned it on and off again. This time it powered up ok but with the DDCS4V2.1 splash screen. Once powered it displays ver: 2018-01-06-PDCNOR.

I did some further tests using a wireless keyboard plugged into the usb port.  I was not able to map all of the keys but quite a few can be controlled in this way.

DDCSV 2.1 4 axis usb keyboard mapping

F3 = Moves x half distance toward zero
F9, / = tab key
F10 = sets sjr to 0.1 then 100%
8,f = highlights F
9,a,s = highlights S0,
g = selects gcode displayed, mach,g54 to g59.
Backspace, Tab = mode key, cont, step, mpg
↑ , 8 = Y+
↓ , 2 = Y-
→, 6 = X+
←, 4 = X-
PageUp , 9  = Z+
PageDn , 3 = Z-
- = run

Scroll Lock, - = enter
1 keypad = sets sro to 0

* = mode - cont, step, mpg

The wireless keyboard I used is not good enough for normal PC use, but the chip(s) may be hackable as a basis for a wireless pendant.

Picclock, thanks for the data.

Please describe the function of the 'g' key.
Does it show more than a single line of code?
Will it run a program in this view?

Thanks, Rob.
