Anet A8 Mill / Engraving Machine

Human: Anet A8 Leadscrew drive At first, I'd like to express my gratitude to SmallArtFly for creating the entire Anet A8 frame in customizable CAD files. Without his contribution, this project wouldn't have been possible.

A file has been created to help identify where each part should be placed (95% complete). Got Bored today, so I made support for second Y Stepper. New Parts have been Added and Complete machine view updated. Firmware Status: Complete The final solution for Firmware is ESTLCAM. It comes with a firmware for Arduino 2560 and Ramps 1.4, which can be used for milling. A nice and simple tool like Cura can also be used as a demo, but it should be purchased (49€). The coder deserves to be paid; the software is really great. https://www.estlcam.de/ So, "printer" is now ready to mill in its final size (240x500mm) and stability. The travelway is 944mm, so it can mill printed parts without any issues or problems, as well as larger parts over 500mm. I will post more Videos when I start making the Anet parts from alloy. Parts For Anet A8 CNC Mill / Engraving Machine For most people, it won't be possible to print the Complete Machine. You'll need at least a heat bed of 440x220cm to print some parts. To solve this problem, use my Anet A8 parts to double your heat bed as suggested. Things needed: 4 Leadscrews T2 8x500mm in 2° or more (I used 2°). 4x Nema 17 Stepper Motors (I took 59 Ncm). 4x Bearing 22x8mm. 11x Linear Bearing LMUU 8mm. 4x Motor - Lead Screw adapter. A lot of m3 Screws in different length from 10mm to 30mm. 1x Mill Spine. Old Arduino 1.0 for 3D printing. Ramps 1.4 for milling and ESTLCAM. https://www.estlcam.de/ For Additional X Axis Stabilizing Steelrods from mill tray are too weak for alloy and need stabilization. 450mm I-Typ Profile. Fotos will be posted when parts are built next weeks. For extension: 1x Leadscrew T2 8x1000mm. 2x steelrod 8x960mm. 2x screws 8x1000mm. 2x I-typ Profiles 1000mm. 6x I-Typ Profile 500mm. 2x I-Typ Profile 250mm. 32x ballbearing 6x3mm for the sleds. Found a solution for Ramps 1.4 Boards with ESTLCAM which comes with firmware for this board, so I won't search for any other. Attention!!!! If you want to print with it using Arduino 1.0, you need to change some things in firmware!!! The 2° lead screws don't like Accelerations over 2 mm/s and a maximum speed of 10 mm/s (but can be higher still testing). Else the Motor clutch is releasing and nothing moves (sounds ugly and can't be good for the stepper). Also, you need to set up the steps per mm in firmware. For me, it was 1600 but depends on your leadscrew and steppers and must be calculated!!!! http://www.prusaprinters.org/calculator/#stepspermmlead
