Thank you for your comments irving. Looks like i did not set the speed and left it at the default value. Sill me. The one thing I had not even considered, is the speed I wanted it to move at. LOL

I will be supporting the lead screw but just wanted to put in a worst case. However, from your spread sheet it makes a massive difference to the power requirements. :surprised:

So, for 4 motors comes in at about £130. It is amazing at this point how many people go for either a driver board or PSU that can not drive them to their full potential.

So, i guess the next logical steps is to research the best buy when it comes down to the drivers and PSU. So much to learn!!

Thank you irving.
