Throwing a cpl of cents in the pot.
One could also raise the temperature of the sand to help resinflow, One might need ro eperiment on what temp tho to not impact the curing cycle in a negative way.

hmm ok. i was thinking of connecting it before plugging in the mains. but i wil not.
any other ways of testing it without connecting the tube first ??

Off to work.. will check back in the morning...

Not hijacking or stealing Your thread.. .but....

Im at the exact same stage... being electrically challenged i need to connect my chinese-ebay-psu to my breaktout board too... Also using the EMC2...

Sorry ppl. Just sending a hello in swedish...

Hah. Född i Roma klosterförsamling jag med :) och precis utbildat mig inom CNC.... Flyttade dock därifrån när jag var 4 (1975)
Sjukt kul att se...

ok thanks. really had liked no use the stuff i already have. (Hate waiting)
I dont find SMT hard at all but is its the "logic level gated power fet" that doesnt fit I guess i'll have to order.
...

hmm... well i have 21pcs of these http://www.irf.com/product-info/datasheets/data/irlml2502.pdf left since i was into modding PiccoZ helis;)
Would they do? and how would i connect them? I really...

ok thanks.
I'll try to find out how to get hold of one and then how to connect it :)

but since i already got these i'll try the 1kOhm too :)

"Do you know the nature of the operating device at p14 or is that PP output??":
p14 is a output pin directly connecter to the parallellport.

HI
First off. I am electrically retarded(nuts)
there.

I have gotten a couple of transistors from a friend that i'de like to use to switch on and off a 300mw red laser-diod thru a laserdriver,...

thanks again Zax. Ill look into PWM then :)
/Ulf

Zax:
thanks M8.
Yes i have a xytable, 2 setups of controllers to choose from and i am running EMC2 on a dedicated computer.
the DAC or PWM im not shure what You meen. i controll on and of of the...

thanks.
but nothing missing it what i stated in previous post ?

btw. cutting balsa with a 300mW diod right now. PAINFULLY slow ;)

Noobwarning:
Im thinking about buying a 40W tube too. what else is needed besides a compatible powersource, mirrors and a lens? the co2 is INSIDE the tube and do not need changing ?? is a...

thanks.
I shall raise my voltage and overcurrent the drives a bit then :)
the 2.2A i pointed out was what i turned the pot to (0.398volt)

HI
NOOB warning

Just finished converting a Proxxon MF70 (really small mill) only took 3 years.
I have a Hobby CNC 4 AUPC REV 2 all axes set to Async and 1/8 step.
i run at 12V now (12Ah...

oops sorry. It Unipolar. Yeah i know about Ohms law but i dont know electronics good enough to see that it applied to this.. thanks :)

I've searched the net alot for one of my steppers i got from an old printer.
I found no specsheet for it at all.

Tag says TEC SPH-54AB-090 3V 3.5Ohm

Now i want to set my hobbycnc driver...

okey no matter. It's as supposed to be. it gets hot during idle. i've gotten answers from another place.

Hi.
Took me 3 years to get this far but i am starting to se some results at last.
I've started converson of a Proxxon MF70 and last night i connected the first axle :)
But when i powered the card...

thankx mate... then those are to good for the proxxon MF70 im buying :)
just to check the other motors then :)

At the bottom of the second table at http://www.cnsoyo.com/cp_1_8_e.asp they state that SY57STH76-2804MA has 18.9 kg-cm torque.
Would that be ~1700 oz/inch or have i messed up as usual ?

I was...

Naturally this depends on the price And since i live in sweden i have to count in a massive shipping fee. But hey. Calculate Your cost and how much $ u want to make per unit.
Maybe it would kick...

ok thanks. ill look into it this weekend :)
Im getting help from a friend that might jus now what You are talking about ;)

I im really a noob at this, but i like a challenge
I want to make a mill and later a FoamCutter. (Im a RC-plane builder/crasher)
Well ive been looking around for about 6month now and i can't figure...
