SmoothStepper USB / Re: smooth stepper works differently in different computers?

« on: April 14, 2010, 12:16:18 PM »

Hi Barry,

Successful troubleshooting has to be carried out in a well organized and methodical manner, if possible recording the results for future reference - so you must excuse me for asking all the questions.

OK, you are switching your spindle on/off with a relay.

Is this relay switching AC mains voltage to the spindle ?.
Is this relay switching a low voltage DC to control a VFD ?.

Hi Barry,

You must get to the bottom of the problem when your spindle is turned on. If you don't then you will almost certainly encounter all sorts of strange behavior with Mach and SS in the future.

Is your spindle switched on/off by a relay or a VFD ?.

Sorry to hear that you guys are having problems with the Powermate plugin.

Are you using the registered version of Mach3 or the demo version ?.
Also what version number of Mach3 are you running please ?.

I wish I was good at doing circuit boards as this would be a breeze for someone who has a clue, lol!

Hi Dave,

If I can isolation route PCB's so can you. Its real easy to do, just try it and see.  Would make a neat job !.

You are quite right Dave, arrays are a much better solution as connecting them all like Xmas tree lights does have it's drawbacks.

Good fortune with your experiments.

Hi Dave,

According to ohm's law  E=I*R and this transposes to R=E/I.

If you have 23 LED's each requiring a current of 25mA then that's 23*25=575mA.
If the p.s.u voltage is 9.5 Volts then R=9.5/0.575 or 17 Ohms.

So if you connect all the LED's in series (observing the correct polarity, of course) with a 17 Ohm resistor that should do it.

The resistor wattage is calculated as W=V*A or W=9.5*0.575 then that's 6 Watts (it will get warm in operation).

Hope this helps,

Tweakie.
