Replacement controller for K40 clones with more options
Posted: Mon Apr 11, 2016 11:54 am
When I got my cheap laser I was already expecting problems with the software, after all the net is full of complaints...
So the first task for me was to find (cheap) replacement for the bad Moshi controller - in my case a real oldie running a 2013 version of "Corel" Laser Draw.
I don't want to write the whole story about it all eveloved again here, so if you have one of these K40 and want to try something different check my Instructable about it.
What is new after changing over to Arduino Mega2560 / Ramps?
1. SD support
2. Full display support with encoder
3. Full support for vector cuts and 8bit photo engravings
4. Full support for 2.5D engravings by engraving height maps
5. No more dongle
6. Use of Inkscape with a corresponding plugin, so you can create in Corel and simply export as SVG for processing through Inkscape - sorry no driver
7. Support of layer naming for laser settings including, power, pulse frequency and pulse lenght
8. Full standalone support if a SD card is used - create your work where you like and place the machine where it suits
All is based on the Turnkey Tyranny firmware and Inkscape plugin.
Changes have been to incorporate new power settings and the support for true 8bit engravings.
All settings have been fully configured to suit all K40 clones with a power supply that uses a laser on and a seperate laser PWM connection, analog or digital does not matter.
If you need support for single pin operation of the laser let me know in the comments of the Instructable or here and I will change the pin assignment accordingly to provide a firmware for these power supplies.
