I think Jerry did not get my example.... Put simply, I ride the "coat tails" of the OEM - they are happy about it as I provide accessories for their product and also bespoke options for their customers. The OEM can get on with their main line manufacturing... The customer has the option of...

Jerry, I make after market parts for 'hobbyist / sport' products - it is my full time job and my business, in a way similar to your business. (without lasers no one would need LPMs and without the main OEM product my business would not exist also). Typically these OEM products cost £300 to...

Ahh Jeez guys! ........... it all look a bit ....... Ain't there enough space in the galaxy for both of you ;-)

These guys are good. Home - OdicForce Lasers Online Shop

That's great! looks like you have lots of headroom for more code / functions:beer: ATB NN:D

Hi, I think a "value" is a co-ordinate pair? - Canvo will be able to confirm. I was getting 10hz refresh using Yoki girl and that was using a 16Mhz ATMega328 + SPI DAC - so I'm sure the Due is banging out the data a lot faster ;-) ATB MM

Hi canvo, Looks good, With the 328 I was getting a lot of flicker with Yoki girl - do you know the time it take for one complete scan of the point table? ATB MM

:beer: The Single mode set could be an option, but I was aiming for the laser to be 1W+. The single modes are much lower power and with such a big host, it kinda needs Powahr:D Anyway, by the time I get the mitsi wings sorted, there will be a single mode megawatt 3.8mm red diode:D ATB MM

OR, A logo /frame needs to be output at ~20 to 25hz minimum to be flicker free. My test would be using a scope to see the maximum number of points can be output before the scan frequency drops below ~25hz. From what I have seen (:thinking:) , ILDA frames / logos have between 700 and 1300...

Hi Wanaburn, page 8 post #184:D Thank you mdunnicus, "top this one"...not sure, but i'm thinking of a next project. Hi Duke, The wings are not fixed and it is killing me the way the beam looks:yabbmad: I'm about to order some optics to have a play with, but I think I'll also need to order...

The laser sounds interesting, please post a link, don't wait for batteries to post the photos My RGB laser is not big conidering it had a LCD display, joystic and microprocessor. ATB MM

I set up a SPI DAC running at 8mhz clock and it tops out at about 700 points. Any more points and the graphics starts to flicker. The DAC / processor Camvo is using loads the DAC by writing to the DAC registers directly, so only takes a few clock cycles, therfore the limiting factor is the...

Pincushion distortion, difficult to describe, but the outer corners of a projected square will distort due to the angel / distance..... errr this might be better:D http://en.wikipedia.org/wiki/Distortion_(optics) For small deflection angles the effect is not very visible. For marking / size...

Super job, glad the PSU has arrived...collourrrrrss :drool: As BB said, would be interestig to see the max points it can output, or the ILDA test frame, or Yuki girl etc. Good work:beer:

Hi Camvo, Looking gooooood :beer:

Sheesh, Impressive use of the comma but the full stop on your keyboard needs fixing, maybe the pound store has some!

I like it when a plan comes together:) I think I'll have to add this one to my list of projects - I've always wanted to build a mini CNC milling engraving machine.:beer: ATB MM

Hi Origami, You are correct, I'm assuming the easy steppers use step and direction so these will work with Mach3 I used a break out board which just buffers the LPT port for protection. I don't think you'll ba able to use a USB to LPT converter as the Mach3 driver will be expecting to see a...

Hi Origami, Mach3 is a PC based software program. It uses the LPT port to send the step and direction signals to the stepper motor drivers. It will synchronise the X & Y (and Z and A) axis to position the workpiece under the tool / laser etc. It uses standard GCode file and this can be...
