On my PC, I want to be able to create and then save a GCode file to an SD card. Then plug that SD into the Arduino+SD-card shield, press "reset" and have it handle it all.



:) Perhaps you...

Hi, I have an old Sherline mill I added steppers to and using an old chopper-style controller that died years back so the Sherline was pushed to the back of the garage and I bought a complete used...

Hmmmm, Rodney Gold with 30 years experience runs a huge engraving and Awards business with many many lasers and 50 employees. If he says Corel Draw and you contradict him from your vast experience in...

Thanks Tweakie,

So simple, beats me why I didn't think of it before. DUH - {slapping forehead}

There are some freeware cutter programs I will have to check out now.

Thanks Bob,

I wasn't aware of that.

After trying that, I again get the arrows and now I can re-size the width. Just another OS "feature" I guess. :D

Hi Tweakie,

A bit of a thread hijack, but I was just looking at your PWM project. What software do you use to generate the GCode for the isolation routing?

Thanks

Dave

:D, yeah, I did. It was a key sequence. I can't remember it right now, but I am sure I have it written down somewhere. It was something like 0, Save, program-number all in rapid succession. That...

Problem solved,

I wrote a rough and dirty Delphi app that displays both. Took about 10 minutes, should not have been so lazy to start with.

@bobsch
Thanks Bob,
I should have mentioned I had tried that but that the CMD prompt window cannot be widened to view the complete line and there is no wrap or horizontal scroll bar for some...

Hi All,

I am looking for a utility that displays both the DOS short filenames and the long filenames. Any suggestion?

I have some old software that runs a cnc machine under DOS 6.22 in win98. I...

I'd be looking at something other than the tube if it is a problem getting worse after heating up. Get a can of spray freeze from Radio Shack and when the laser is warmed up and has dropped power,...

It's been a long time since I was reading about it and I do not use Lasercut, but I seem to recall it is in the Configuration file in the same folder as the program. The same file that contains the...

Are you sure it is the tube? The Synrad tubes have a huge work life. From the Synrad site...
"Proven operating lifetimes >45,000 hours"

So, 45,000 divided by 8 hour-days = 5,625 days divided by...

In my experience, banding is usually as a result of resizing a pic and matching the dpi of the laser.

Try to ensure that the dpi of the pic is one the laser is naturally capable of.

Re-size...

I can't help with additives, but if you can minimize the amount of light getting to the water the algae cannot grow. I use black plastic tubing and the water tank is covered. I have not yet had...

Can't help with the seller's reputations but I do know about lasers.

The tube when new will probably be putting out more than 130W it is not an exact science making the power level. They aim for...

Do some searching here for a contributor called "mononeuron" or something close to that. I seem to recall he had used the Link Motion or was waiting on the new version. That was at least a year back,...

You mean like this...

That amount of alignment error is not all that important unless it is on the first mirror. I would leave it alone.

The stepper, what symptoms? How long is this piece of string?

Swap the X and Y...

Glad you fixed it, but for future reference, the first thing you should do is move the graphic along one of the axis and burn again. In this case I would have moved it up the Y axis. That would...

Glad to hear you are getting on well with it.

You cannot cut Lexan (Polycarbonate) with a laser under about 1000 Watts. It absorbs the heat too readily and just melts and leaves a powdery deposit....

Wow, that looks like some quality equipment there. Nice looking sold mirror mounts and air assist etc.

The manual button for Z-axis is pretty normal. I know a lot of guys with auto-focus and they...

Providing it is a CO2 laser. If it is an Nd:YAG it will eat through Plexi glass in a heartbeat.

The CO2 wavelength is almost totally absorbed by the glass and Plexi glass at a distance.

At the...

Be careful what you wish for. A LOT of guys with auto-focus disable it as the touch probe gets in the way of stuff. Ask anyone with auto-focus and see if they have never crashed into the touch rod....

Hi Breazr,

I thought I replied to this yesterday. Must not have clicked "Submit" :)

Can you get the Mazak into waiting mode for the PC to send?

Have you studied the file you downloaded? Does...

It might not be a speed issue.

Are you using cast or extruded acrylic? Extruded marks and cuts very poorly. Cast is cheaper and marks and cuts much better, but you may get very fine edge cracking...

Be careful running simulated DOS on w2000 and later unless they have a device driver written specifically for it. From w2000 the processor is controlled by the system kernel. Trying to run a laser...

Hi,

It's not just soft water it is the stuff in it. My guess is the pump was cavitating slightly and generated some air bubbles, these collected in the tube at a narrowing spot or a sharp bend. As...

A Collimator lens may help a little but with 16W you are not going to gain much.
