Thread: My Machine
Kip "Seriously" I always smile and I say that with a serious amount of seriousness.
Is that a nice smile or the scowl in the picture ?
Gonna build a new machine! Any suggestions on how I could improve on my existing machine would be appreciated.
Similar flying bridge design but with single (larger) ballscrew for X axis and THK fully supported rail on all axis.
I'm interested in this whole business with the laser. I had no idea DVD diodes were powerful enough to do anything... other than read dvds... and make home made laser pointers.
Do you think you could post a little info on how you did it?
Well what do you want to know about DVD laser burning?
You could just buy a 300mw DVD diode in a 12x30 mm housing with lens and driver board off Ebay for about £30, Seller I think is in South Korea but had a good track record with UK customers.
I made a mount to hold the diode where my spindle would usually go, The driver board I used needed a 6v Regulated supply so I just gave it 6v via a regulator switched via a Solid state relay driven directly by the parallel port.
I then wrote a simple script that swapped out Z moves in the G Code created by Cad software for M codes to turn laser on and off, The etching of a baby on some wood was done with a 180mw 635nm DVD laser diode.
Focusing the laser takes a little trial and error, But I got a spot size down to 0.07mm, Even 180mw at a spot size that small is a fair amount of energy.
Please feel free to ask me any questions as I know I ramble and talk shit sometimes.
