What material are you using for these mounts Ron and how much do they weigh please ?

From my experience of other programs Mach far exceeds their versatility. If you you purchase Mach you won't regret it.
Good luck with your carvings.

Hi Mlinder,

I know it's perhaps not what you want to hear but the easiest solution, I think, would be to use a PC rather than a laptop.

Usually the two holes at either end of the con rod are cnc drilled/milled and these are used to secure it to a sacrifical plate (wood perhaps) then it is profile cut.

Hope this helps.

FAQs / Re: Can't get any response from parallel port

A stand alone monitor for the parallel port called 'Parmon' can be downloaded from here :-

With this you can see which pins are switched or activated by Mach.

That's looking good - what are you going to make with it ?. Don't forget to post pics of your work.

Hi Prof,

From what I see your steppers are wired correctly and your power supply is OK as well - nothing to worry about there.

Whilst experimenting I would try this :-

Each of he step and direction pins should be held at +5V through a resistor of say 100K of so and then pulling a step pin low (0V) should produce a step (active low).

Do not connect any of your step/direction pins directly to the 12V supply or the +5V either.

Certainly does look good.

A damn sight better than that old enclosure which I threw out.

Hi Prof,

Looking at the circuit - the enable pins 4,7,14 I am not certain if these should be left high or if they should be taken to ground.
Also pins 18-25 of the LPT should be ground on your circuit.

That's normal the steppers should lock when power is applied. Nothing wrong with your IC alternatives (I think). Go into Mach config / ports and pins / motor outputs and check that you have the step and direction pins configured correctly (also is the active high/low set correctly). In the Port Setup and Axis Selection try selecting Sherline 1/2 pulse mode.

You are certainly on your way. Hope this helps.
