#Welcome to the 3DLS Lead Screw Drive #Aluminum Frame 3D Printer #by Morninglion Industries! #As seen on HACKADAY.com You can find us on Discord! For tips, help and 3DLS specific stuff! Here's a 4k render of the machine 3DLS Youtube playlist #Download the latest files here! Always updated with the latest and greatest there. Thingiverse seems to struggle with this. #This is fully operational #and printing now! I have been rebuilding it with all the latest design parts and taking lots of pictures. Here's a gallery of all the pictures. Video of it at 120mm/sec printing the back for my Rugged Raspberry Pi Tablet Here's another Video printing at 150mm/sec outrunning my extruder the print didn't turn out well because the extruder could not keep up at these speeds. Follow up here and the timelapse of the failed print is here. #Current Status: #Test print done, all per this build! Full view Full view Full view Full view Full view GCODE used for Benchy Here's the time lapse of the 3D Benchy print #Then I strapped it up by one side... Setting up the test Timelapse strapped up. Checking out the results! #I am writing the instructions now! Printing at 100mm/sec with accel set to 3000 on X and Y. Max speed is 300mm/sec. The precision is so good that the little compensations done by Prusa Slicer get printed out instead of compensating for anything. Machine is done. Marlin 2.0.3 included. Requires SKR 1.3 to meet speed requirements and SKR 1.4 Turbo is highly recommended. Machine runs best with TMC2208 on Z and Extruders, The closed loop controllers are required on X and Y for flawless operation. Here's some pictures and links: Slicer Settings, Prusa Slicer It's now at 300 Accel X and Y with 100mm/sec top speed. There's still some over extrusion in the corners and some following of the infill. I am going to set infill/edge overlap to 0. A video of it running for noise levels The frame is based on Pheneeny's great AM8 The extrusions used are the same as theirs but that's it. #Everything except the frame is my design. You can retrofit most of this back onto an AM8 bit by bit however there's a lot of tweaks here. #Specs: Prusa Type 3D Printer with No Belts! 235x235x235 Build Area but this is scalable to larger.

This is much faster, more reliable and quieter than the BIQU offering. Same for the main board, been using the MKS Robin Nano and it's great. Super reliable with TMC2209 and dual Z drivers for G34 level. There's lots of updated parts out there as separate things in my designs. These have been used as is or modified and assembled here into a standalone Cartesian 3D Printer with No Belts! #Full BOM: Items that are direct links are the parts the machine is designed to fit. 380mm Smooth Rods x 4 436mm Smooth Rods x 2 for X SC8UU Bearing Holders x 7 LM8UU Bearings x 7 I like Drylin here. 340mm 2040 Extrusion x 2 313mm 2040 Extrusion x 3 440mm 2040 Extrusion x 2 I got my extrusions on Ebay from PD-Tech Order 315mm and put in the notes to cut it to 313mm for AM8.

It's all about speed with lead screws. The speed a stepper can run at on a controller is proportional to the CPU speed. The CPU is what generates the pulses required to run the motor. As an example a RAMPS with Arduino MEGA 2560 runs at 16 MHZ. This limits the step generation to about 10MHZ before the CPU gets bogged down and begins to miss steps, this is with a single stepper too, divide that across 4 and you can quickly run into issues. This is with Marlin FW. Now on a board with a faster CPU like a SKR 1.4 Turbo at 120MHZ can run the steppers up to 100MHZ pretty easily. This means a much higher top speed without bogging the CPU down and causing issues. Also the 32bit board has much more RAM for running Marlin effectively. Now there's still other considerations for speed and this machine will never be quiet. It's not meant to be fast or silent though you are trading those in for a much more precise control and quality in the print. As it sits I am limiting speeds to 100mm/sec at quad stepping in X and Y. Since the screw has to turn 4x faster for the same speed compared to the belt this runs it at the same steps per mm as the belt since it's 1/4th less steps. This has no real effect on accuracy. It's all about elim
