This is the email content:

i m from romania,and i buy last yaer a cnc machine router from you company

i am very satisfied of you re product cnc wood router i work many  pieces of wood furniture but  suddenlyit appearce a little problem who growing up
first the machine do not came at home origin...she goet at the limit and she kick the board limit
then i try to reset the limit in  remote in machine setup but  it wont works.

Here is the solution:

Firstly,there is home point back direction set in the DSP remote controller. The direction should be X +,Y+, Z-.
Then,it is because there is no command from wire to limit sensor. Please check the limist sensor wire if with power, or use metal piece to touch the limit sensor of cnc wood router to see if the light of limit sensor on the control board( in control cabinet) is bright or not.
