ok just been down the the cave to try again. I have set things like this K1 n K2 set back to 2 again. i set the setting to

steps per = 80
velocity = 1400
acceleration = 150

The Torque is a lot better set like this . I can run with out stalling and it seems faster than before.
I haven't cut anything yet with it like this but i tried to stall the motor by hand and i can but it takes a lot of force to do so.

what is the difference between velocity and acceleration ?


Any way it seems we are getting some where. I will try cutting something tomorrow and see how we get on.

In the long term i think upgrade is in order at some point.
I would like to say thanks for sticking with me on this. I seem to be learning so much so fast. I should be used to that being a heating engineer . All the help has been much appreciated
