But this will take a long time for development and I think it's very unpleasant having a laser cutter at home which is not working because software needs to be done. I still want to develop a cool firmware for raspberryPI. For controlling standard TTL lasers there would be additional electronics needed.Īfter thinking for a long time I now decided to proceed with grbl and arduino. Another problem is that raspberryPi gpio pins offer only 3.3V. Unfortunately the gpio library is not able to generate the needed I/O port frequency which I would need to get a good speed of the machine axes. I know, I promised that I would us a raspberryPi only. Yesterday for the first time I've had a successful run of my machine using 'grbl'.

After a cutting or engraving process was done give the fume extractor some time to remove all fumes. So please be advised, that a laser cutter provides visible and invisible danger and can harm you really bad! If you want to filter the gas using char coal filters, please use a CO - Detector or any monitoring of CO gas (carbon monoxide) while working. That was a really unpleasant feeling - and dangerous!

I immediately turned off the cutter by pushing the emergency stop button and ran away from that machine. I became dizzy immediately and felt awkward. Unfortunately I was a little bit careless at saturday and inhaled a little bit of the carbon monoxide gas. Especially this makes the fume extractor dangerous if it's not completely air tight and being operated indoors. Most fumes are adsorbing to the char coal there is no smell anymore at the exhaust. The char coal filter is doing a great job. I now attached a filter and a blower to my laser cutter. It can diffuse though walls and is more or less the same weight as air which means it can go everywhere. It's not aching in your throat while inhaling. Carbon monoxide is known as " silent killer". The fumes, especially while cutting or engraving wood, contain carbon monoxide. Not only the laser can destroy your eyes if you handle it the wrong way. The microswitches are mounted at the end position for each axis.Ī Lasercutter is a very dangerous device. I use one breadboard for the DC/DC controller, another one for RPi to Laser and servo connection.Īd the beginning the axes are being referenced. Our Raspberry Pi should be accessible using WIFI

Once the file is uploaded to the cutter, you don't need the pc anymore. It will have only one button: Emergency off / on. This cutter is designed for being fully operational outdoors, using 12V solar energy. If you change the file in the meanwhile using smb, another file is being processed. If you push the emergency switch and unlock again, it repeats the g-code. If the program is finished, the machine stops. As soon as you unlock the machine it starts to cut the actual g-code program. The printer contains only one security switch. In future there should be support for svg files, too. Using the smb-protocol you can easily upload your G-code, png images or logo files (development language).

The pi has a WiFi dongle and a preconfigured samba server. Therefore this laser cutter takes only one input voltage: 12V The heart of the system is a raspberry pi using custom software. In "Wasteland Energy" I promised that all my projects will be connectable to a home solar kit.
