Stealthburner Beta: MGN12H, CR-Touch, Creality Spider

prusaprinters

::edits again:: So I've come across a much more elegant solution for the Orbiter 2 mounting setup @ https://github.com/elcrni/Voron-Mods/tree/main/Orbiter_2.0_SB_CW2_EnclosedI recommend this over the one in here. So skip the orbiter mounting piece and cover and use this instead.::more edits - August 12th:: So after printing out the revised parts, there's about a 3.5mm difference in the placement of the nozzle, which should help cool the filament much better than before. The spots in the front section where the mounting screws sit needed to be auged out a bit (I just used a ¼ inch drill bit to remove a small amount so that the 2 halves sit flush when screws and inserts go in place with the hotend), but I did do another edit of the front section but have not tested it out. It'll remain in the untested folder until tested, use at own discretion. The other parts will be put on my machine in the next day or 3, but should be good to go as is.::edit August 7th 2022 – I just got to thinking about where the nozzle sits in relation to the original setup with the dragon hotend (the one I used the fan duct from for the spider hotend edit) and I noticed I was quite a bit off, so I redid the toolhead sections to better position where the nozzle sits (so it's closer to the original) which should help with cooling issues for the filament. I've also adjusted the orbiter mounting block to fit the newer toolhead pieces, so you'll have to redo that as well if you previously printed these. Right now they're in the untested folder until I can test them out. Use at own risk, you may have to reprint them later.------------------------------------------------------------------------------------------------------Voron Stealthburner Beta for Creality Spider V1 hotend with Orbiter 2.0 extruder (direct drive) and CR-Touch abl.All mods done in Tinkercad as I'm slowly learning to use 3d software.Orbiter 2.0 front shroud and mount remixed from: Orbiter V2.0 mount + StealthBurner Front Blower Cover with Cutout for Voron 2.4  by willyreborn on Thingiverse: https://www.thingiverse.com/thing:5249381All other files remixed from the official Voron Stealthburner github files, toolhead used for mod was phaetus bms 6.All rights to their respective creators.This mod is meant for the Creality spider hotend only, as the toolhead and fanshroud sections had to be extended approx 4mm (so I don't think it'll work with other setups). Orbiter 2 mount had to be extended slightly due to the toolhead adjustments for the Spider hotend, so I simplified it and joined the 2 pieces for it into one (eliminating a few screws and inserts along the way).Special screws needed:  2 - 4mmx50mm socket cap screws, 3 - 3mmx40mm socket cap screws. These can be hard to source at most stores, I had to order off amazon 25+ count of each, only around 10is each type though iirc. Locations for screws is in the images/special screw stuff folder. The 2 4mm socket cap screws go through the front fan shroud, through the toolhead sections, and into the x-carriage (I went with 4mm due to the 3mm screws being hard to source afforably in that length without getting bent ones). The holes thorough the front shroud and toolhead sections were increased to fit this modification.You'll need approx 18 3mm heat inserts, and 2 4mm heat inserts. I had to order these in sets of 50-100, so hopefully you can find them locally. More info in the images/inserts folder. Best practice is to put in all heat inserts before assembling everything, it'll save you some headaches. Note: there are a few "optional" areas for the 3mm inserts (2 on the toolhead main body and 2 on the x-carriage). These aren't manditory, but can help in the long run (the 2 on the x-carriage can be skipped as it's tight enough to hold with just m3 screws, but it is plastic so it can strip easily over time).The x-carriage setup is for the Switchwire setup using an mgn12h rail setup, but I modded it to use the cr-touch instead of the other abl options. There are 3 cr-touch mount brackets - when I printed with PETG the first one worked fine, but when printed with PLA I had to adjust it a smidge, so there's 2 others you can try. YMMV.When putting together the x-carriage with the cr-touch, you have to put the cr-touch and bracket together first using 3mm screws (button socket cap) 6mm long iirc with m3 hexnuts. You then take that and slide it into place inside the first half of the carriage, the screw head will sit in the recessed area to help hold it in place (it should be snug). Then add the other half of the carriage, being sure to secure the cr-touch and bracket in place (again the screw head has a recess to sit into). The 2 halves may not be exactly touching, but after putting in the 3mmx40mm screws with hex nuts (3 each) it should sit together without having to crank it super tight. The block/insert for mounting to the rail has 4 3mm heat inserts, make sure to insert from the back side (flat - no channel for wiring to go through when assembled). Screw this block/insert to the mgn12h block on the rail, then screw the rest of the x-carriage to it.The block for the orbiter 2.0 is pretty simple. Use the 4 3mm heat inserts, let cool for at least 3 min to help avoid the inserts pulling out when tightening screws. Put orbiter onto block with motor sticking towards the back of the block (the end with no heat inserts), screw in place, and combine with x-carriage (there's a tab on the back of the block that slides into the apropriate area on the x-carriage). The extruder cover is a bit flimsy but mainly to help the setup look a bit cleaner for now (working on coming up with a better solution).There are some untested items included, with the x-carriage halves missing the extra sections I had put in place to help provide enough material to hold the cr-touch and bracket in place (where the original abl hardware was to be located). Those, and the "half" cable cover are untested but there if you want to try them out.All other assembly is pretty intuitive, and there's plenty of guides out there for this fan/hotend assembly. If you need help please let me know and I'll see if I can throw an assembly video together.Thanks for looking and reading, any questions and comments are welcome! (just no trash talk please).And yes my printer is a work in progress, so don't bash on it too hard =)
