My FabKit MK 5 was causing problems: When starting the laser operation, the smoothieboard was resetet and the whole process aborted. You had to re-establish the serial connection and hope that it would work this time. The issue became more and more frequent over time …
So it was time for an upgrade:
I contacted Bonne and he informed me that the smoothieboard was probably damaged and that we couldn’t replace it because there was no smoothieboard available. So the idea was to upgrade to a Ruida board. Ruida boards are the new quasi standard for laser controllers, and MK 6 will come with this controller as well.
That means for my older maschine a completely new controller, external stepper driver and a different connection for the compressor. Also, it doesn’t work with the LaserWeb software anymore, you are now stuck with the Lightburn software.
The controller has a fancy monitor that can be used to control the machine completely on its own, (without any additional computer). Once a cutfile have been created and saved to the controller you can run it allover again. The cursor keys move the laserhead and you can adjust the focus conveniently on the machine. There are a few new safety precautions (the lid has to be opened and closed once before the first use).
So I am quite satisfied and can recommend the upgrade to all those who have problems with dropouts of the smoothie board.
the first project was the housing for the display, mounted at the place of the former mini pc.
