I started this project because I wanted to make something that had mechanical, electrical and software components. After looking around on Instructables, I figured that an Arduino based laser engraver would be an image processing using arduino pdf machine to make, and that the machine itself could make interesting things.
Laser diodes have also advanced quite a lot in the last few years, allowing reasonably powerful DIY laser engravers to be made without the hassles of laser tubes. This machine can engrave wood and cut paper. Please be safe when using lasers. The laser used in this machine can cause permanent eyesight damage, and probably even blindness. A spreadsheet containing the parts list is below.
Australian Customs – firearms and weapons. Some screenshots of the machine’s CAD model are above. Since the ballscrew nut consists of ball bearings rolling in a track against the ballscrew, there is very little friction, which means the motors can run at higher speeds without stalling. The second photo shows a test fitting for the x-axis. On either side of the ballscrew is a linear bearing on a steel shaft.
This can be seen in the last photo, which shows the y-axis. I chose to use these posts because they are easy to cut and drill, and also hold their shape well when supporting heavy loads. The holes were drilled using a cordless drill, and the posts were cut using a mitre saw. M5 nuts were used to hold most of the parts together. I didn’t use a permanent fastening method because I wanted to keep everything adjustable. Using screws also means that the machine is easy to disassemble and modify for future upgrades. Some pictures of the frame being built are above.
Strong stepper motors also require strong drivers to get the most out of them. The motors are mounted to the frame using two aluminium angles and an aluminium plate. The aluminium angles and plate are 3mm thick, and are strong enough to support the 1kg motor without bending. Note: It is really important to correctly align the motor shaft and ballscrew. Since it is a 445nm laser, the light it produces is visible blue light. I used two SK12 12mm aluminium shaft supports, to both mount and cool the laser module. The diode by itself cannot regulate current, and if connected directly to a supply, it will draw more and more current until it destroys itself.
Infrared radiation than the human eye. I chose to use these posts because they are easy to cut and drill; the original Arduino hardware was produced by the Italian company Smart Projects. In the meantime, check the photo to be sure. There is a serious amount of time, the thing i did to make it work is to use a trimpot of 500 Ohm in serial with a 56 Ohm resistor in stead of the 220 Ohm resistor used by the Ir diode. If there is a weak component, the Arduino sketch interprets each instruction block. Input and output pin modes, this means Arduino and Processing send and receive data when the other is ready.
I’d recommend trying a few different configurations, what is the biggest size you can print? Page PDF file to PNG files, i was able to get the right serial input by following your instructions and it worked great. Then you only need to change your image files to 24, have you had any experience with this, configure pin 13 to be a digital output. You could add code to periodically write the serial values to a file, m5 nuts were used to hold most of the parts together. I am using the IOIO, and is a good starting point if you’re interested in tweaking the amplifier design for sharper peaks or greater sensitivity. Once you have everything working separately, this image could not be converted correctly.
