Mach SDK plugin questions and answers. / Re: PowerMate Plugin

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.

Hi Sam,

Very nice Trident - you need to mount it leaning away from the door, somewhere to hang the bath robes !!

Ahh - Poor little big hornet.

Sam - "Stay tuned folks" I have a cool idea in the pipe.

Dave - Exactly the same oscillating movement as your pencil. My movement is adjustable and was set at about 0.5mm with zero Z about 0.2mm above the work but there is a certain amount of overshoot so the retract height has to allow for this or the work is spoiled during the G0 positioning moves.
The finished work is not as neat as with conventional, rotary engraving but I think it's main advantage would be with hard materials such as SS.

In that case there is more than a good chance that your port is damaged.
Assuming the rest of the PC is running OK you need to obtain a PCI parallel port card or get another PC motherboard.
