And if seems like a familiar name before–you’d be right–as they’re also the mind behind Octolapse, the 3D printing timelapse tool that’s a hobbyist crowd favorite. But with more folks jumping on the bandwagon to use these motion control boards for other non-printing applications, we’re starting to see arc implementations on boards running Marlin, Smoothieware, and the Duet flavor of RepRap Firmware.įor the curious, this program is kindly both well documented on operating principles and open source. A few years ago, this would’ve been uncommon since, technically, 3D printing and STL file only requires moving in straight line segments. This whole program operates under the assumption that your 3D printer’s onboard motion controller accepts arc commands, specifically G2 and G3. A concise description of Arc Welder’s main algorithm as pulled from the docs These constraints act such that the resulting post-processing is true to the original to a very high degree of detail.

The program is written such that arcs only replace segments if (1) an arc can completely intersect all the segment-to-segment intersections and (2) the error in distance between segment and arc representation is within a certain threshold. “Now wait”, you might say, “isn’t an arc an approximation of these line segments?” And yes–you’re right! But here lies the magic behind Arc Welder. The result is that the number of GCode commands needed to represent the model drop dramatically as connected clusters of segment commands become single arc commands. The result is that some printers simply stutter or slow down the print, resulting in print times that are much higher than they should be.Įnter Arc Welder, a GCode compression tool written by that scrutinizes GCode files, hunts for these tiny segments, and attempts to replace contiguous clusters of them with a smaller number of arcs. Unfortunately, some printers actually struggle to print these models at the desired speeds, not because of some mechanical limitation, but because the processor cannot recalculate the velocities of these segments fast enough. This is just the nature of the beast lots of detail translates into lots of teeny segments. But when the features of the original model are dense, or when the model is representing small curves, slicers end up creating a proliferation of teeny segments to represent this information.

This has the downside of requiring your computer to be on to continue printing, but it's another option that gets you nicer integration in the Simplify 3D UI.When the slicer software for a 3D printer model files into GCode, it’s essentially creating a sequential list of connected line segments, organized by layer. When you connect the client to the server, software running on your computer will see that device just like any other USB device. Instead of the Repetier Server, you'd run the Virtualhere server, and then set up the Virtualhere client on your computer. Of course, that's not nearly as nice as the functionality you describe with Repetier Host and Repetier Server.Īnother option would be to use something like Virtualhere, which is a USB over TCP system. Not sure how you'd handle that with Repetier Server, but there may even be a way to interact with some API and start the print directly when you save your gcode in Simplify. It should be really easy to rsync your gcode out to the "watched" folder in octoprint. On the Process Settings -> Scripts -> Starting Script screen in Simplif圓D, there's a field labeled "Additional terminal commands for post processing".
