You could maybe change the way that it is calculated? Something in HAL which switches the calculation method.

M52 turns adaptive feed on and off too. You could insert that in the G-code (maybe as an optional block?)

What problem are you trying to address?

One way would be to insert a mux HAL function with one input from the adaptive feed input and one set to 1, then trigger the mux switch from your python code. (either by creating and driving a HAL pin, or (more clumsily) by using
os.system("halcmd setp mux.0.sel 1")

@andypugh or any one can help

How would I set the adaptive-feed value with a nml-command?  if there is one;

just like setting EMC_TRAJ_SET_RAPID_SCALE or EMC_TRAJ_SET_MAX_VELOCITY ??

thank's in advance

looks like there is only a message to enable/disable it.
Setting the value is only thru HAL

@cmorley  thank's, I was almost expecting that;

What would it take ( How To ) to implement that input into the nml-channal;
23. Adding custom NML commands....
I think I'm not ready for that just yet; .... GGgggrrrr;

Why can't you just set the HAL pin?

@cmorley  thank's,
Yes I could do it, using the halPin;
But up to this point the UI is just depending on the NML channel;
I wanted to avoid the HAL, and just see how far I can get; that's all.

best regards
