Hello,
I haven't got much knowledge in Mach3Mill.
So I hope you can help me to solve my problem:
I want to regulate the speed and the direction of the motors with one input signal each.
The input signal is given by a force sensor in voltage.
Is this possible?
Can you say me how I have to configurate Mach3 Mill?
Thanks!
Kind regards, Tine

What kind of motors are you trying to control ?
Can you describe a force sensor? What does it output?
-
i have got step motors with 0,05° per mm.
do you need special or more exact informations?
The force Sensor gives out voltage signals of 0-2V depending on the force.

Sorry but mach is a pulse generator it does NOT have any means to use INputs to control the pulse train as is needed in your application.
Sorry,(;-) TP

If your question could be changed to:
Can I change the feedrate of movement accordanly to an input (in this case your force sensor).
Yes you can. You should right a brain, that changes the feedrate in porpotion to your input signal (that in your case would be analog).
First steps: Get a pokeys, read the analog input connected to the pokeys. If you can do that, then you need to read how a brain is done, but is not too hard.

thank you filipe, that sounds very great.
I searched the Mach3Mill users manual for the "Brain" and "Potkeys" how you called it. But I didn't find any descriptions.
Maybe you can help me?

For brains, look under the videos there are a good example.
For pokeys, it is a hardware piece normally cheap that can handle several inputs and outputs, including 5, if I am not in mistake, analog inputs.
Start with the pokeys to see if you can read the analog inputs. It is quite easy, then write the brains.
