Hi all Has anyone any experience of a Proxxon MF70 milling machine. I am considering buying one purely for use in clockmaking. Any comments would be welcome

Although have tried that in the past with no problems I will try again just to be sure.

Sort of working. Got both directions working but after a complete revolution the stepper stafts to creep.

Finally got my setup to go in both directions, however the motor after doing a revolution in either direction starts to slowly creep a little then becomes faster. Only way to stop it is by pressing the reset button. Seems to be a possible problem with either the lcd shield or the motor driver...

ok, everything seems to be working fine except the reverse! So this is my setup:- Arduino uno Sainsmart lcd display shield TB 6560 stepper motor controller. Anyone with same setup show me how they have it connected or have any ideas.

I really must thank Chuck and others for their valuable information. Having no experience of coding the info here has been most useful. My only problem with Chucks code (from post #50) or my setup is the lack of reverse direction. Can anyone tell me where I may be going wrong?

is it possible to post details of the programme you refer to?

If I change my worm drive to a 36.1, am I correct in saying that this would solve the problem?

I tried the maths and came up with the same as yourself 33.3, t was from this onwards that my confusion set in. Not sure what you mean by 'set my jog to 125 steps'.

Ok more detail of my project. I have built a small dividing head (tony jeffree design). This initially was to be used with indexing plates. It has a 30.1 worm drive. My thoughts were to replace the indexing plates with a stepper motor. I have a nema 17 1.8deg. stepper. The final outcome...

yes have gone through page 1 and hooked up pretty much as described. My problem is trying to figure out what code I need to use that will give me the possibility of cutting a 96 tooth wheel. The more I look at examples of what people have done the more confused I get!!:(

Hello all having spent alarge number of hours reading through this thread my poor mind is now frazzled! So I hope that you good people could give me an uncomplicated answer to my problem as follows:- I want to cut a clock wheel with 96 teeth using a stepper motor as a means of division. The...
