So i just bought this particular machine https://www.ebay.es/itm/293746046167 . It comes with this usb control board

Also the stepper drivers are TX14207


I can comunícate with the computer throw the usb and mach3 to the machine. The problem is that the machine is missing steps on every single axis so it maked impossible to make any work...

Things that i already check:
Tighten the Z axis.
Slowing down speed and velocity
Calibrate the axis throw mach3.
Different computer with different Windows (w7 32bits and w10 x64).

I dont know what more can i do... Im so lost and this consume 4 full days of trials trying to figure the problem...

As i said all axis can mové also the spindle but for some reason they are loosing steps.

Machine is cncest 6040 ????
