General Mach Discussion / Re: G31 Bug?

« on: February 19, 2009, 03:19:44 AM »

Update.

Restarted Mach and it works fine now - stops as it is supposed to. Could it have been something left in a buffer from the previous program ?.

Thought I would try this and mine does the same - 'no probe, no stop'.

If the rest of the Dart looks as good as the dash it will really be something. Good work Ed.

Third party software and hardware support forums. / Re: 3 Axis Stepper and Spindle Control Circuit Diagrams

Hi Prof,

On the electronics side of things :-

As your motors are only 600mA and 800mA I think they would get hot if they are drawing 10Amps.
Yes you do need current limiters.

The formulas you need are:-

E=I x R and W=V x A

so at 12V, 600ma a series resistance of 20ohms, 7watts would be required and for 12V, 800mA a series resistance of 15ohms, 9watts would be required.
As high wattage resistors are relatively expensive Tom has used bulbs in his design, which is what I suggest you use.

Hope this helps,

Tweakie.

Glad you got it working Prof.

As for setting up the motors - all the info is in the support doc. Here is a link:-

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.

FAQs / Re: Mach3 will not run?

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.

FAQs / Re: milling a part

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

« on: February 16, 2009, 07:56:56 AM »

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.
