No I was not aware of that, so I need to take all the earths separately to a connection on the back of the machine, choc strip, then one wire to the bolt on the control box?
While I am on I wonder if you can help with the amount of travel of the Axis, for instance the machine is set up for mm however the actual movement on the axis's do not correspond with the amount that was inputted. I presume that if I enter G0 X10 then it should move 10 centimetres but it only moves approx. 6 centimetres. Am I correct in thinking that if I enter a code of G0 X0.05 then it should move 5mm. I get very confused with Metric but I have a feeling that the 6040 has a metric screw thread, although I cannot find any information on it now.
