Charmilles Robofil 310 speed problem

Good morning,


We have been having this unsolvable problem with our Robo 310 for quite some time now , E3 setting (u) XS25A.TEC - 30mm steel should get a speed of 3.8 speed/min ,yet the max speed is 1.2 but 0.8 for the most of the piece.

The Strategy values are reading as normal as they were before ,regardless, we cleaned the ground cables, changed spools, contact blades , signal cable ,cleaned the water tank and same result, values are reading as normal yet no change whatsoever in cutting speeds.

Any tip would be appreciated as at this point we are getting out of ideas as to what might be causing this.

Regards,
