Remap M6: Is this philosophy possible? was created by zz912

Hello,

I have done Remap M6 pro Brotherc TC-211. I made it by O-word. It worked, but it wasn't perfect. So I started learning python.

I would like to ask if it is possible to implement:
1) I will make HAL component:

import hal
h = hal.component("atc-remap")
h.newpin("in", hal.HAL_FLOAT, hal.HAL_IN)
h.newpin("out", hal.HAL_FLOAT, hal.HAL_OUT)
.....
h.ready()

2) In Remap code I would like control pins from this compontent:

h['out'] = 1002.45

Is possible import component from another file.py ?

github.com/LinuxCNC/linuxcnc/blob/master...n-stdglue/stdglue.py

This shows loading a hal component in a remap

Do you think this part?

def build_hal(self):
import hal
try:
h=hal.component('remapStat')
h.newpin("tool", hal.HAL_S32, hal.HAL_OUT)
h.newpin("wear", hal.HAL_S32, hal.HAL_OUT)
h.ready()
self.hal_tool_comp = h
except Exception as e:
print(e)

But this part create new component, not use exist component. Or not?

Yes it makes a new component.

Is there a way to just modify an already existing component?

Or is there a way to modify this component created in remap with another python code?

I have one ATC, but a friend wants to have 2 ways of control. One automatic via M6 and the other sequential via buttons.

You can use normal HAL commands to interact with the remap component.
What do you mean 'modify this component created in remap' ?

I'll try to explain it another way.

I can change value HAL PIN by M-code like this:
forum.linuxcnc.org/38-general-linuxcnc-q...ith-g-m-codes#268483

I can change value HAL PIN own component:

import hal
h = hal.component("own")
h.newpin("out", hal.HAL_FLOAT, hal.HAL_OUT)
h.ready()
h['out'] = 1002.45

But how change for example ini.x.max_limit by python?

What version of linuxcnc are you using?

How about:
hal.set_p("pinname","10")
linuxcnc.org/docs/2.9/html/hal/halmodule.html#_set_p

The restriction there is the pin must not be connected to anything.

Another way is to have the two component pins feed into a 'steering' component (like an OR component) that then is connected to the x.maxlimit pin.

I use RIP instalation Branche 2.9

I guess I already understood.

hal.set_p("pinname","10")

"pinname" is not only name of pin, but it is whole name of pin AND component.

So in my case:

hal.set_p("ini.x.max_limit","10")

Is it right?
