T2 Engraving / Re: 'port' to turn on laser?
« on: November 16, 2019, 10:33:21 AM »
If I use the old control board, laser works fine. When I go to the other control board, it doesn't get any power. (Only the laser, the motors DO get power, and are controlled through software just fine).  I had to change something in software back when I originally set up the z-axis board, and now need to set it back. I believe it tells the control board where the on-off for the laser is.  I'm not talking about com2 or com 3, but something actually on the control board itself

T2 Engraving / 'port' to turn on laser?
« on: November 16, 2019, 09:08:38 AM »
So I have 2 cnc control boards.  One came with my cheap-o laser engraver setup, the other I ordered separately off Ebay because it has z axis control.

I've switched back to my original controller, but can't get the laser to turn on.  I seem to recall that I had to switch 'something' to like port 11, or something like that to get the laser to work before. 

If this makes any sense, please give me a hand.

Here you go

Awesome, thanks! My drag chains I've ordered don't have the nice mounting pieces on the ends, so I'm going to have to be a bit more custom, but that gives me ideas.

Nice drag chain setup, and I like the cable bundle on top... I'll have to incorporate that also.

Thanks for the pic!  Can you take another pic of the side of the drag chain? I want to see how you connected it up...

T2 Engraving / Stronger laser?
« on: August 24, 2019, 03:56:17 PM »
So my laser engraver kit came with what is advertised as a 3w laser.  It does ok, but I have to run the machine a bit on the slow side to get it done.

I see that up to 15w lasers are sold on Ebay for right around $100 bux.  Some get good reviews but a guy said that the supposed 15w laser he received was actually a 4.5 watt.  He apparently had the scientific equipment to measure it's output.

So, does anyone know of a good source for an upgraded laser module?   Is 15 Watt just an advertising scam, and they don't actually exist? (Blue ray diode is what I'm referring to)

What do you guys suggest?

I don't think that would work for my setup... I have a couple drag chains on the way that I'll be incorporating into my setup though.

Well I feel stupid now...

I made an intricate pattern of vector circles, within squares, within more circles.  I got the wobble after running the scan, and then discovered that my Y axis wheels were just barely finger tight. I had loosened the x-axis wheels, slid them tight for a really nice tight fit, and had loosened the y axis to do the same, when I must have been called away to do something else and forgot to re-tighten.  Problem solved, grrr.  Thanks for the suggestions guys.

I did the gradient pattern on several materials, to make speed/power adjustments and if I do the 50cm vector box, it is perfect.  It seems to be the raster scan that is slightly out of 'tightness'.  It seemed better if not using the timesaving steps, such as speeding up in the blank areas, but that is SOOOO slow, haha.

T2 Engraving / Crooked boarder?
« on: August 23, 2019, 12:32:33 PM »
So, I engraved an image onto some 1/4" mdf.

The boarder, as seen in image 1 is perfectly straight.

The engraving came out a bit wobbly.  Any ideas/fixes?

I'm engraving at speed 500, and selected Bi-Directional, skip blank lines, and rapid skip blank. (Takes forever otherwise) But, are these causing the line issues?

Thanks!

Do you have a picture as an example?

The problem I have is that the cables are JUST long enough to reach when the machine is in the 0,0 position, farthest away from the control board.

So I probably have to get longer cables (Or, make longer, I do have 4 wire security cable) Then have it run through the drag chain, or whatever.  I've already made a hanger out of 1/8" metal rod, but the wires will reach the far end, then get in the way of the x axis slider when it goes to the far back of the work area.  I just need to get the side wires out of the way.

Grrrrrr, I looked for 30 minutes and of course, as soon as I posted the question, I found it a couple min later.

It's a drag chain.

T2 Engraving / Cable guide thing?
« on: July 29, 2019, 08:18:13 PM »
So my cable management is a bit tricky because this is a really cheap ebay engraver I bought. 

Does anyone know what the guide 'chain" for the wires is called?  The wire goes through the middle of it, and it rolls and unrolls up and down the table while the engraver is moving.  Looks like a plastic motorcycle drive chain, haha.  I can't seem to find what it is supposed to be called.

Figured I'd try to buy one off ebay to pimp my ride.

T2 Engraving / Re: TTL laser vs PWM (Analog?)
« on: July 27, 2019, 08:43:18 AM »
Probably so.  This controller board has 2 types of laser outputs.  A 2 wire named "laser" and a 3 wire named "PWM Laser"

(I had thought I had seen ttl, but as it turns out, I did not.)

So currently, I'm just plugged into the "Laser" output, since I only have 2 pins/wires to work with.  Again, it's working, so I'm calling it good.

I'll pretend I totally understood all of that, and will water it down to:

"Don't mess with anything since it works now"
