Anet A8 AM8

thingiverse

I'm modifying my Anet A8 to AM8. I didn't use a conversion kit, so I designed everything myself. Here's what you'll need: The aluminum profiles are 20x40 with a 5mm hole in the middle of each nut. Later, M6 screws will be cut into these holes. To start, we'll drill holes in the three Z-profiles. Then, we'll assemble the X-frames, drilling 4 x 6mm holes at 10 and 30mm from the edges (right and left). We'll also add a third X-frame, bolting it to the other two with M3 screws. Next, we'll take the two Y-profiles (450mm long) and lay them flat on the table. From one side, we'll drill holes at 290mm into each nut, as previously described. It's essential to be precise here. We'll then cut threads in the Y- and Z-profiles so that they can be attached later using M6 screws. You'll need 12 x M6x40 screws and 4 x M6x60 screws (which can be longer if necessary). The entire frame will now be assembled. Since my version is longer than the original A8, I added a custom bed with two linear rods, four bearings, and four clips for the rod ends. These are attached using Nuts. I also replaced the aluminum bed plate from the A8 with an acrylic one. Later, we'll add the Y-endstop switch to this plate. Since the belt is too short, I bought a 5mm belt kit. We'll attach it to the original fittings for now. Next, we'll add the Y-axis motor holder and Y-axis belt tensioner STLs. These will be attached using M4x16 screws. The tensioner is very tight, so you may need to file it slightly. To tighten the belt, use an M5x60 screw. The head should face towards the print bed. Now that we have all the parts assembled, let's move on to the main components: I'm keeping the Arduino and Ramps configuration from the Anet A8, so I designed two PCBs: one for the MOSFETs and one for the Arduino with Ramps. The power supply is attached sideways to the aluminum frame. The Ramps cooler is also attached sideways to the outside of the aluminum frame. Now that we have all the STL files assembled as per my design, let's move on to the rear components: From the back, we'll attach the heat sink holder where the two fans will be inserted. Each fan will receive a nozzle. If you have any questions or suggestions, please feel free to ask.
