I have a Re-ARM board from Panucatt Devices, and I just received a K40 Laser Cutter. I am impressed with what I have read about how well Smoothieware works with Laser Cutters. I got the Re-ARM to go along with a RAMPS board and LCD display for another project, but since I now have the K40, I would like to use it there.
On the surface, it seems like a simple task. There is X and Y axis motors to control and home switches for each. Then there is the Laser control. I suspect that since the Re-ARM board is intended for the RAMPS board, the pinouts may be different than other Smoothieboards. Therefore, I am expecting this to be a matter of figuring out the config and making sure the laser is connected correctly.
My biggest issue is that I am completely unfamiliar with ARM controllers and Smoothieware. I have experience with AVR processors, grbl, and other CNC applications. I plan to use external stepper drivers (at least initially), so only need to deal with step and direction outputs. The Re-ARM will be connected to a 12864 LCD, and I may want to customize the menu.
I am hoping that there are people here that can help me with sorting this out. I have spent hours with Google and searching this forum, and I am finding the answers seem to be scattered about the internet. Once my machine is working, I will post the solutions on one of my web pages so others can find the info in one place.
Since I am inexperienced with Smoothieware, I am looking for an overview of what is required to configure it for the laser, and a brief explanation of how it controls its power. Since the Re-ARM is already set up for a RAMPS and 12864 LCD, I am thinking to start by getting that going, then add X and Y axis motion and home switches. Then work on the laser.
Can someone please explain what the connections to the laser PSU are, and the method to get Smoothieware to control it?
