Benedikt, can the USB port support a HAL/HID keyboard with Pandora? If so i can program a Teensy for a custom layout mini panel keyboard with screen ref buttons and feed/ spindle override knobs. Pandora would just need to be able to map a keyboard input to functions. This way we have quick access to functions.

I'm trying to also identify options and what it can do as there seams to be some hidden features, so it may be helpful with integration with pandora i.e we may just need to reference an internal M command that is already there. Is there any latency or processing issues running this app in parallel.

That would be great. A list of what needs to be changed and one of the hidden features is always useful!
Parallel processing should work fine. The controller can easily do that at the same time.
Also yes USB HID is fully supported. However there is no actual linux driver for the keypad. The keypad seems to be directly controlled via I2C. I will see what I can do ;)

So M98 will invoke the controller to run a referenced sub routine. The sub routine is just standard G code and then is using M99 command to end the sub routine. So to stop your spindle and pause for a tool change your sub routine would be:

G53 to refer back to machine coordinates
G01 Z to a safe height
M5 to stop the spindle
G01 XYZ to your tool change position
G0 for a Pause and Cycle start
M3 to turn the spindle back on
T# G49 to reference the tool length offset from the saved table
G54 to ref back to work concordance
M99 to terminate the sub routine.

Here is what i need to understand, Mach can be told to run a VB script or M98 when it sees a M6 or ignore it, can this controller be told to run a M98 when it sees a M6 or do we need to swap out M6 commands in our code for m98.. some CAM postprocessors can be made to do this automatically, But a controller ref M6 to m98 XXXX would be awesome. Also, can the M98 be stored on the controller or needs to be added to the end of the Gcode for M98 reference. There are G and M codes for driving outputs high and low, pauses etc so a full ATC such as UGV is posable as a sub

Chris,
Thanks for the input - since I use a 'manual' toolchange, I need a program stop whilst I go through the undo-replace-tighten routine and I can't see how that will happen with a G0 - or am I just being dim this morning?
The rest of it is very clear and when I get 5 spare moments, I will investigate further...

Folks - I am a machinist hobbyist from Michigan, USA, and have been watching this thread with great interest. The work on reverse engineering this little thing has been nothing short of amazing! :bugeye:

I am building a 2'x4' cnc router and would like to try a DDSCV1 on it, but I have a question that I am hoping you can answer. It will have two steppers on the long axis. Can this unit drive them from separate outputs, or do I have to tie them together on one output? This is easy to do with linuxcnc; how is it done with the DDSCV1?

And to the gentleman who wrote the Pandora configurator PHP script: Part of my day job is web interface design. May I have a copy of your scripts so that I may tinker with it? I like what you have done, but I think we can spiff up the page with some tabs and such, and maybe a guided wizard.

Thanks!

Mark in Dowling, MI

I correctly understood you, 2 motors on one axis? DDCSV does not allow you to configure the subordinate axis as in the Linux CNC or MACH3
