The measurement from the centre of one tooth to the centre of the next is 3mm The gap between the teeth is 1.4mm The ratio of the gearing I have driving the lead screw is 1 to 1.2 so 70 teeth on the stepper motor and 84 teeth on the lead screw Hammering as you describe it is what it sounds like on coarse thread settings. Thanks for the information on the current settings, I will try that in the morning and see how it goes. I hope your surface grinder project gets sorted soon, good luck and thankyou for your help Pete
