![]() Rome-based Alessandro originally began working on the project back inbut life and other ventures took over, so his sewing machine hack was placed on the back burner for a while. Will be a complete waste of effort.Employing an impressive range of making skills, Alessandro Benanti built his own embroidery machine. Like Jake saideven the most heavy duty, rigid 3D printers are just barely capable of being used as even a rotary engraver. It is not even close to a rigid machine, and just barely rigid enough for FDM. You would be hard pressed to get it to do simple engraving in butter. ![]() Random freezes are often an issue of your bootloader or arduino distro. So why am I bringing this up here on this discussion? Now if I had plans to implement this whole thing, it would be even more useful to me.ĭIY would be great. The heated nozzle and block always seem to leak which sucks. It works on Debian provided by Raspberry Pi Foundation. Although I am currently using clearpath servos. ![]() ![]() Probably fast enough, and software on a lever that I can comprehend and fit into my head. Another project used the PRU as stepper driver and could get upto 1. It was a real bummer when I discovered that. Maximum step frequency was some 20 to 30kHz. This way the random latency cancels itself out to some degree that might be enough.īut I dont know for sure. ![]() Has anyone used this? Does the Pi support a real-time thread? This will then let you run a real-time thread. This method of direct control offers some very interesting possibilities for small, low-cost, CNC projects. These little modules connect up to a dedicated power supply and handle the considerable current draw of the steppers, all you need to do is provide them the number of steps and direction of travel. The only thing missing is the software to interpret the G-Code and command the steppers over GPIO, which thanks to, we now have. Historically this has been something of a necessary evil, as there was really no way to directly control stepper motors with a computer fast enough to be useful. This board takes commands from a computer, often in the form of G-Code, and interprets that into movement commands to the connected stepper motors. ![]()
