![]() ![]() Arthur Wolf over at Smoothieware offered his assistance so hopefully we can work that out soon. I have what I need to build, but I want to find someone to work with me to put the polar coordinate firmware package together before I do. I'm still debating on the best way to mechanically connect the 3 riser carriages to the motor(s). I plan to use one or more Nema 23s for the Z axis wired parallel to external stepper controller(s). The 600mm diameter heat bed will bolt to the top of that. ![]() The Z axis will consist of a 2020 extrusion hexagon platform attached to the three 6020 risers. Distance, angle, and speed are the XY positioning variables. Both X and Y axis are rotational, and driven by opposing Nema 17s using 6mm interlocking belts for the X, and 9mm interlocking belts for the Y. That assembly will be CNC machined and put together as a self-contained unit that bolts to the top hexagon horizontals. I'm departing from a conventional delta on this design, and replacing the effector and arms with the polar XY rotational assembly. ![]() All that remains as I originally planned for delta printer hardware I bought for that design. I plan to use 6mm clear Lexan for the full height door, framed with 4020 V-Slot extrusions. I'm using powder coated MDF between all the risers for the infill panels and to make the structure rigid. The six 60° outside corners are 2020 extrusions I bought from Musimi. The frame uses OpenBuilds V-Slot vertical 6020 X 1500mm extrusions much as you've shown, with hexagon rather than triangle 6020 V-Slot horizontals at the top and bottom. I'm using a delta chassis but not the arms and effector. We are the same age so I know the feeling. Thanks for your feedback.any suggestions or critique is appreciated. Any thoughts on that? Any other issues come to mind? The mechanical design allows end to end movement of the print head through the 0,0 center coordinate, but I'm thinking some fixed distance past center is really all that is needed to give full print coverage across the bed. Is anyone familiar with a software package that exists to manage these movements that can be configured for Smoothieware? I have the Smoothieboard hardware already so I'd like to stick with that. My question to the group stems from my lack of knowledge on polar coordinate plotting and integration of that into the conventional 3D print process chain. Since this will be an enclosed chamber printer, I'm leaning toward moving the bed and keeping the XY stationary so drive motors and components are fixed outside the heat chamber. Either case the bed doesn't rotate, the XY rotates per the drawing. I have the option of moving the bed on the Z axis, or leaving it fixed as per a conventional delta, and letting the XY mechanism travel along the Z legs. You can also select from this drop down to switch between your different printers.I have designed a printer that uses a combo polar/linear XY mechanism and a conventional Z axis all on a Delta chassis design. Printer Name: If you’ve given your printer a name (Manage > Settings) that’ll be displayed here. Manage: More details on managing your printer down below in the “Manage” Printer Page section Here you’ll upload or import STL/OBJ/3MF files and get them ready for printing. Be careful! GCode is machine specific and has to be prepared for the specific printer you’re using.īuild Plate / Slicer: We call our slicer the “Build Plate”. ![]() G-Code Job: An upload dialog box that allows you to bypass the built in slicer (#7) and upload a job that you’ve already sliced. Temperatures: Nozzle 1, Nozzle 2 (if applicable), the Heated Bed, and Chamber temperature are displayed here, underneath the start button.ĬANVAS: The advanced-feature slicer available to accounts with an active subscription. Print Details: Time elapsed, time remaining, percentage completed. Printer Status: Here the printer tells you if it’s idle, printing, waiting for you to clear the last print, or any other status your printer has. See the “Printer’s Queue” section further down the page for more info. The first job (the leftmost job) is first in queue. If you’ve shared your printer with others, they can send jobs to the printer as well (depending on their level of access). Print Queue: Beneath the printer’s camera feed, you’ll see jobs that have been sent to the printer. ![]()
