Re: New guy finishing off a mini mill build
Attachment 29582
it could be some of the problem Doddy, but i can see the same pattern in this acrylic test, same settings just different material.
But all in all i am chuffed to bits with the fact the thing works, i do have one more question - who am i kidding, like its going t be the last question!!!
i cut a complex pocket file with lots of short moves and direction changes and the noise/resonance from the steppers was horrible, the file cut ok but seemed to be rattling the fillings out of the machine, can i tune some of this out playing with the stepper tuning?

Re: New guy finishing off a mini mill build
That looks like some quite bad backlash.
I'd start with measuring to see what backlash there is, before worrying about any tuning.
Re: New guy finishing off a mini mill build
After you check the backlash you might check the acceleration setting in your controller software as well. Winding this back will increase the cuting time for complex shapes but reduce the shaking.
