Drop in E3DV6 for Davinci Pro (True Drop in!)

thingiverse

Much credit goes out to the original Designer, bdwalker. The original design can be viewed here: https://www.thingiverse.com/thing:1328848. This is my first time sharing something with the community. I do engineering work, so it's not like I'm new to updating or building things. You can have confidence that this will work for you just as well as it does for me. If you're having trouble or need help, feel free to message or comment. I'll get back to you as soon as possible. Keep in mind that this is an updated design, which means it fixes issues the original designer may not have had time to address. If you're unsure about this being the right thing for you, consider this: I've fixed issues with the original design, making it easier and more reliable. This is a direct drop-in cartridge for the XYZPrinting Davinci 1.0 Pro. Mine has the 3 in 1 feature, but that doesn't make a difference. If you're doing this mod, be aware that you'll need to set the Z offset. You may also need to manually adjust the bed leveling knobs to bring the bed down, as the limit of the offset is only 10mm. This extends your hotend by about 13mm. I started with 3D printing a month ago and had experience in design work and other engineering aspects. But I was blown away by how easy it was to get started. In three weeks, I've already accumulated over 300 hours of print time. Now, onto the design! This redesign takes care of all the issues with the original drop-in cartridge that I personally encountered. The clamp and shroud remain the same for ease of downloading. Here are the problems I fixed: 1. The original PCB board filament guide offset issue: This was a major problem for me. The filament feeding would get stuck due to the 1.5mm offset "forward" position of the E3D insert. It caused numerous printing issues, and I had to use a small screwdriver to cut the filament at an angle and fiddle with it to get it to feed smoothly. 2. Nowhere to put the wires: The original design suggested putting the wires in the corner of the shroud and carrier, but it was impossible for me to do so without creating a mess. I fixed this by adding insets for M3 nuts, which will hold the fan securely in place. 3. Fan not working? Fan shroud mounting loose? Fixed both: The fan wasn't operating due to shorting out on the screw. I added insets for 2 M3 nuts and used an M3 x 8mm fastener, which solved two problems at once – the fan shorting and the fan shroud coming loose every print. 4. Hot end won't stay stationary in mount: The hot end was loose in the mount due to poor design. I reinforced the portion of the design over the heatsink and added crushable "teeth" to the mount, making it impossible for the hotend to be "clipped" straight in like the original design. I printed mine with Esun CF Nylon Filament. To install: * Soldering iron (small wires make it tough without clips) * Screwdriver or hex keys * Torx depending on your availability of fasteners (I used small Torx for disassembly) Alternatively, you can purchase a PCB off the original designer, who added screw terminals. The PCB costs $50. Install parts needed: * Super Glue (gel gorilla superglue works best) * 6 - #4 x 3/4 Screws * 6 - #4 Washers * 2 - M3 x 12mm Machine Screws * 2 - M3 x 8mm Machine Screws * 4 - M3 Nuts One thing I still want to fix is adding a screw to the bottom of the fan shroud. Currently, you can just put a bead of glue along the bottom and hold it for about 1 minute to cure.
