Adimlab BMG & E3D V6 Setup for Creality Style 3-Wheel Back Plate - Remix

prusaprinters

This is a remix of "Bondtech BMG on a Taz 4 (or Taz 3-5--needs slight mod for Taz 6)" by jaln". I like how the design is fairly simple, the parts cooler air duct is integrated and the visibility of the printhead is good. If you want this mod for linear rails on your Adimlab printer then click this link: https://www.thingiverse.com/thing:4367312 If you want to do this mod on your Adimlab Gantry Pro with the Gantry Pro backplate then go here: https://www.thingiverse.com/thing:4779487 The main goal of this remix was to remix the mount to fit on an Adimlab Gantry printer, but this will work on a lot of printers that use a Creality style x-carriage. For this version, on the Adimlab printer, I found the x-axis belt anchors were too high so I made some little blocks to put the belt into. You will need to mirror the model in your slicer to print the second one. If you don't have an x-axis belt tensioner on your printer print one now. It will be almost impossible to get the belt tension adjusted otherwise. I used these belt holders https://www.thingiverse.com/thing:2354961 in combination with a small screw and nut on the belt and looped it back. See the pictures. I made the holding bracket taller so it will also act as a strain relief for the cable (the intent here is to get rid of the Adimlab cable chain due to some broken wiring issues). The air duct plugs for this version also fit better and the inside plug has a tab to make it easier to install. I suggest using a small amount of silicone sealant or loctite to hold the plugs in place and allow removal if needed. I didn't include the probe mount but it can be downloaded from the original thing here: https://www.thingiverse.com/thing:2844819. I have added a mount for a BL Touch probe. *PARTS YOU WILL NEED FOR THIS MOD - GET BEFORE YOU START* BMG Extruder (Bondtech or Clone) E3D V6 Hotend E3D Heat sink air duct or another one of your choice 5015 Blower Fan A pancake stepper, I used one called a "hybrid" that is between a pancake and normal size stepper. It is 30mm in depth. GT2 Belt x 6mm wide HARDWARE:*IMPORTANT NOTE: You will need M3 x 40mm screws to mount the extruder. You may have to shorten the one that goes on the top left side of the extruder a little.* For the rest, you will need mostly M3 screws, 1 countersunk M3 for the stepper and I recommend short self-tapping M4's to mount the parts cooler duct. Use self-tapping M3's for the BL Touch bracket. 3/26/21: UPDATE, modified the size of the air duct hole to allow the M3 x 40mm screw to go all the way through the air duct. This will help make mounting the stepper easier. The plugs for the air duct are also bigger. 5/20/20: UPDATE, added a second version of the cable holding bracket and the Adimlab extruder PCB cover. This holder allows the Adimlab extruder PCB to be mounted and adds nicer cable management. Bonus it also has the Adimlab logo on it! Thanks to BA from the Adimlab FB group for this contribution! 5/17/20: UPDATE, changed the BL Touch mount so it is in the front left and closer to the nozzle. The offset is X: -27.5 and Y: -19.0. Added an E3D V6 fan duct for a 30mm fan. Loaded new 3D model pics. 5/15/20: UPDATE, BL Touch mount is too low. Removed it until it can be fixed. Note: this is fixed now. Uploaded new parts. 5/10/20: UPDATE, Changed the screw holes to mount the BL Touch bracket to the parts cooler so they will fit M3 self-tapping screws. Uploaded parts cooler model. 5/7/20: UPDATE, Removed all the 4 wheel models. I'll add those to another post to avoid confusion. The pic of the 3D model still shows the 4 wheel model for now. Added a little reinforcement to the fan arm on the backplate, made the holding bracket taller with more holes for tie straps for the cable, and made the plugs just a little bigger so they fit tighter. Also added a hole to the tabbed plug to help with cable management. Last, added a BL Touch mount. Print Settings Infill: 30%-50% Notes: I use Cura so I don't know how to do this with other slicers. Cura has support blockers that will not print support wherever you place them. I used support blockers on the sides of the air duct so it would have support only in the middle of the duct. This worked out well and was easy to remove, but be careful. I also used a support blocker on the parts cooler to block support in the air duct and the output holes. The only support needed was on the outside. Other settings, I suggest 3 or more walls and a good strong infill like cubic or cubic subdivision with 30-50 percent infill. Post-Printing The air ducts fit together well but may need a small amount of filing for a perfect fit. For the BMG extruder set the firmware initial steps/mm to 415. To center the nozzle on the bed (Adimlab gantry printer) set in the firmware: X_MIN _POS -5 and Y_MIN_POS -9 If you mount a BL Touch use these offsets in the firmware: X: -27.5 Y: -19.0.
