General Discussion / Re: Nose knows best
« on: March 31, 2018, 05:06:14 PM »
So hooked up an 2 axis mana board that I had not used for about year. Plug everything in, all lights are good. Start to smell what smells like a computer that has been running for a long time. The smell gets stronger...something inside tells me I should be worried. The smell gets stronger and a little because I cant figure what it is ....... POOF


Suppose it is static electricity that has taken your stepper driver. In fact, they are not so robust of that kind of voltage. But as others point out, a driver does not cost a lot of money and is easy to exchange.

firefox and duckduckgo...
but I am somewhat paranoid!!
=)

You get sick of believing something like that.     :-\

I do not know your search engine but it does not work very well if it can find what you're looking for.

thanks for this,  I will take a look.
Out of curiosity, which browser do you use (looks like I need to change mine!!) and with search engine do you use (I use duckduckgo!!)?
=)

Better late than never.   

I'm using Google Chrome and Google Search.    :)

Regards Leif.

Have the same old eyes, who prefer to read everything at least 1 meter away.    :'(

Depends on your laser wattage.
I think the 2.5w is closer to 9mm

No, 0.9 mm in front of wet black powder.   ;)

T2 Engraving / Re: Need help, odd burn on right side
« on: February 04, 2018, 07:25:36 PM »
Yes, there are four things I can imagine can make you get the result.

1. Missing focus where the burning is not performed.
2. The slate is not so susceptible to burning on the spot, it is a natural matriale.
3. There is an error in the diode electronics or the laser diode is not cooled properly.
4. Power supply is too small the seed does not have a stable output voltage.

I will guess point 2 is the most obvious for mistake. Try and run slower with the laser over that place.

Points 3 and 4 allow you to check and make a long line across a matriale that is more homogeneous to burn. The line must be evenly burned throughout its length. Oak is suitable for such a test.

Hmm... Simulation view looks fine.  These burns were both on slate which are both pretty flat.  It's just an odd streaky pattern, but only on the right side, the left side is perfectly fine.

Do you burn in either direction or only when the carriage runs from left to right?

General Discussion / Re: Laser Power issue
« on: January 29, 2018, 09:04:29 AM »
Well, I guess I spoke too soon. This morning I was doing a traditional HD logo in T2 and at the start everything seemed OK. But shortly I found it is not OK. What it is doing as it burns at the normal power, when it goes to the next letter or shape it will go dim and then maybe it will be normal again. It is like the power randomly goes from normal to dim. Have any suggestions what it may be. I am assuming it may be hardware.

My guess will be it's your power supply that is weak or too small.

Not bad, actually really nice. There you've just hit the spot.   :)

General Discussion / Re: Technique for Creamic tiles with diode laser
« on: January 05, 2018, 10:06:36 PM »
Yes how beautiful.

Had even thought of trying the same on a white tile, but lack of black spray paint in my house has made it only been at the thought. I have to go to town and buy something.    :D

Cutting / Re: Cutting Styrene Plastic
« on: December 30, 2017, 05:07:29 PM »
PVC is even worse, it develops at high temperature hydrochloric acid - be careful

Hydrochloric acid as such, is not hazardous to health, provided you do not take a bath in the liquid.

Styrene develops vapor/smoke that is suspected of being highly cancer-inducing. You probably do not notice that before after 10-40 years!   ;)

Happy New Year, Greetings Leif.

General Discussion / Re: Video shows brass inserts, I've got plastic tubes
« on: December 22, 2017, 03:15:31 AM »
The assembly video shows brass threaded inserts before and after the wheel. For spacers.  Ive got back plastic tubing spacers to go on each side of the wheel. What's up with that. How cheap can they go and will they hold up?

Generally, plastic spacers are bad as they are easily tied together, brass spacers are much better. If you do not have brass spacers you can drill some 4mm nuts up with an 5mm drill and use 2-3 pieces in extension. They are almost better than brass spacers.

Merry Christmas, Leif
