See the Laser Cutter Working Group forum. Laser Material Processing , 4th ed, Springer-Verlag, Poorman Mutli-Lux setup method – CandlePowerForums The main modification would be that you probably only want to drop the Vcc but not the LD’s Vin, so you would add the diodes between Vin on the driver board and the paralleled Vcc pins on the , where in Download’s example the extra diodes LEDs are dropping volts from the Vcc and from the third LED’s supply. You have seen the videos on the internet, but I havent found yet a source of tips and tricks. You may be onto something here. Some people say it works ok when out of spec, as long as you heatsink them well. The primary factors affecting cutting speed v are laser beam power P , the material being cut and its thickness h.

Amc Laser Driver – softwaredino
The thinner your burning tip is the more concentrated power you get. G4 PXXX adds a pause in miliseconds. It also has a PWM pin. While from and on, everybody’s favorite diode seems to be the so called blue nm M harvested from old lasrr 1,4W and 2W varietythose diodes tend to be quite expensive for experimentation.
Once it has started burning its easier to continue. I was just curious if you had any surefires and if the sinks lasdr made for your L2 fit your surefire?
With this quite more hefty diode you can expect to cut any color of paper, light plywood, thin leather etc. A very cheap and stable solution is the AMC chip that can be easily found as flashlight driver. Members Current visitors New profile posts Search profile ajc7135. And drop-out voltage of 1N54xx diode 3A is 0.
There are some similar projects to create an Open Source lasre cutter, some of them already shipping devices:.
L AMC Constant Current mA V High Power LED Driving SOT IC
Question about amc and nm LD. A PoIV graph is now available in the forum http: Instead of tweaking acceleration you can also use Teacup Firmwarewhich allows feedrates down to F1.
Views Read View source View history. Retrieved from ” https: The PT driver is more versatile and it can be set with a sense resistor. Navigation menu Personal tools Create account Log in. Its a super simple constant current regulator that works up to 6V so the 5V PC power supply is enough. The same and more expensive rule applies to even beefier lasers that make their rounds on ebay. With a software separating the processing data for the single lasers you can speedup the time per sheet along with the count of lasers Laser Material Processing4th ed, Springer-Verlag, BShanahan14rulz Well-known member Sep 16, You have seen the videos on the internet, but I havent found yet a source of tips and tricks.

BShanahan14rulz Well-known member Aug 9, Is it better to use a relatively cool room-temperature air, or b hot air? Joined Jul 25, Messages Likes 8 Points 0. I built a few of nm with v5, microboost.
Vf of nm LD is over 4. It only seems to take a reference on the Vcc pin, according to the datasheet, though. Getting the right distance from the material you want to cut is essential and this is more true for weak lasers. Can I build 1. Using a laser on a reprap machine requires usually lower speeds.
I’m sure you have a few unknown bin Cree LEDs you could test with There is a serious risk of getting blind when working with lasers. Severance energy can be thought of as the laser beam energy needed to make a cut of 1 mm 2 area i.
