Widows print driver & control system for chinese machines.

[Dan Hammerstron]

Kay, the software you use is CorelDraw and you send to the laser the same as you used to? also the speed is doubled from 50in. per to 100 in. per. according to there manual they sent, it says its windows driver that works in any format the same as any other print driver, I was given 2 company names that use there system as yet only talked with one, that has converted a Chinese machine, also has American machines. he is very happy, especially with the 256 grey scale abilities of which he has only 8 and 16. so far I am liking what I have heard.

[Dave Sheldrake]

Is that Inches per minute Dan?

especially with the 256 grey scale abilities of which he has only 8 and 16.

I would ask for some clarification on this... I'm assuming he means he can set the power on 256 levels? The ULS has 8 colors for different powers in the same drawing, and you can set 16 different levels based upon a grayscale image for 2.5D work. This is completely different than dithering 256-level grayscale images for photorealstic engravings.

Graphic1.jpgI just talked to Tom Hart, he is the President of the Co. It is a WYCIWYG and works the same as the universal driver from CorelDraw, I have a universal and love it. The 256 greyscale is for 3d carvings for linear output, this is the company that built the controllers for universal up to the quite recently, but if you need proof I am going on his words, he has offered me one to try and I am going to take him up on it, he of course wants a deposit of 25%.

Graphic1.jpgThis Co. made the controllers for ULS up till quite recently according to Thomas Hart the CEO. of Testra, He has offered to let me try this out on my 1390 Keyland laser and I am going to take him up on it.

[Dave Sheldrake]

Are you looking at fitting one to a ULS or retro fitting one to a Chinese laser?

but if you need proof I am going on his words

I don't have need of proof Dan, I'm not looking at buying one. You asked if they are any good and some doubts have been raised that's all.

cheers

Dan, I use AutoCAD 2000i not Coreldraw. Mr. Hart was the person that I dealt with. The hardware is pretty solid but their support after the sale and their claims are not so much. I have never had such an experience with any tech device and I have dealt with most of the major electronics firms. I designed and had my own microcontroller based product for sale for over ten years so I know something about how to deal with hardware/software issues.
Best of luck in your project. I wish Testra had followed thru on my unit. $2000 was a lot to spend only to be left in the lurch.

I use the times 2 and a 1/2 rule when buying stuff
2x the running cost quoted by salesmen and 1/2 the feature/performance claims - if it still makes economic sense applying the rule ... then I go for it.

[Dave Sheldrake]

Just had a look at the Keyland machine.

Flying mirror at 100 inches per second isn't happening on that machine. 24 ips maybe for engraving and 8ips for cutting, that machine just isn't built to take the claimed kinetic energy figures. Much like the claims of Chinese lasers cutting 30mm acrylic, in theory it will do it but the end product is going to be a worthless piece of melted plastic.

I know what you mean Rod, the one thing that all laser cutter vendors seem to have is an economical command of the truth.

Agreed... I'd bet the shake at the ends of the travel would cause some serious blur in the engraving, assuming they try to turn around fast enough for any real-world speed. Otherwise, they're counting on a lot of overshoot, which means they make 100ips in movement, but the overshoot is so long the engraving time is the equivalent of a 50ips machine.

Good point Dan and the larger overshoot if required will cut down the working area by a fair bit.

Well, there's one way around that... just allow the head to slam into the wall on each side 20G accel/decel

[Dan Hammerstron]

Wow, what constructive intelligent posts...gotta be proud.

Wow, what constructive intelligent posts...gotta be proud.

It's what is classified as humor here, Dan... interjecting a bit of levity into a potentially soul-crushing tech argument.

ACME pinball laser

Kidding aside, the figures just don't stack up, 0 -100 ips - 0 on a Chinese based machine irrespective of the controller generates some seriously wacky numbers.

cheers
