Mini Stealth v2 Is Available

[Dylwad]

Ender 3 version with the btt eddy and sherpa mini has been working pretty good, but I'm ready to move over to a protoxtruder and cartographer with a linear rail x for faster TPU. I have all the parts, how's the carto mount coming?

For the top mounted linear rail mods, there are two long screws that go right through the metal exclusion zone for the Beacon/Cartographer and the aluminum extrusion might be a problem as well.

The front mounted versions don't have this problem but the probe might need to be installed after the belt is secured.

I am half tempted to try making an x-carriage based on the design I created for my delta printer 10 years ago but I guess I'm already busy enough..

Nice, I'm going with the front mounted rail, seemed easier and I don't mind losing some more bed. Looks like the carto might just squeeze in there perfect. I run one on a stealthburner in the same spot and it's amazing, and even better with the survey-beta tap function. Mines been accurate to a few microsteps.  

 

I have a CNC plasma at the shop that uses cam followers on box tube, with springs to tension them. Rack and pinion with servos. We got almost 20 years out of the motion system on the last one, and it's the worst environment for just about any linear rail system. Surprisingly accurate too.

I have added 74 new shrouds to the GitHub that allow mounting a probe on the right side of the toolhead.

There are brackets available for six different probes.

Here are the Ender 3 - Switchwire style Beacon3D x-carriages for the front mounted MGN12 and MGN9H linear carriages.

I have also updated all of the Ender 3 MGN12 x-carriages to fit MGN12C and MGN12H linear carriages.

Thank you! Printing it now. Ill maybe get around to installing a new 20x20 x rail and stuff this week. The Cartographer Tap function works great on my enderwire, hopefully the ender Z axis is up for it.

The Biqu MicroProbe fits on the Ender 3 front-mount linear rail mods quite well.

The new files are in the repo.

There is now a crop-top shroud that fits the Goliath Air hotend in the GitHub repo. It is the first Mini Stealth shroud that uses a 2510 fan for cooling the hotend's heat break but this is an option that I would like to add to the other shrouds as well. The Goliath fits onto any of the DragonACE cores so, most of the extruders should fit.

Were there significant changes made to the LGX Lite shroud?  I had already printed it and the probe bracket(s) I needed and was having some difficulty that I eventually solved.   The bracket holes didn't seem to want to bite with M3 screws, so I used m2.5 helicoil inserts instead.  Just wondering if I should re-print it?

Yeah sorry, the self threading holes can be very dependent on flow and print tolerances, especially on the side-probe brackets which were designed for M2.5 flathead screws. They can also suffer from first layer squish and require opening the hole a little. If you have printed pieces that work then there is no need to re-print anything unless you want to move the probe to the other side.

Excuse me if this is already answered.

if I install this in a Voron v0.2 will I lose x or y travel?

The X axis shouldn't loose any travel, but the Y axis will loose between 3 and 5mm of travel.

Hey

Starting to build a Voron 2.4 and am going to use the components I was going to use for an ender clone that I decided not to move forward with, and among them is an orbiter 2.0 with filament sensor and a Rapido UHF, which I see that v2 covers

The kit I bought (from fysetc) includes a klicky probe, but didnt find stls with that name, but Omron; I'm guessing that's why I need to grab? (Although I have a biqu microprobe as well and am MAYBE using that instead)

Correct, the Klicky fits into the Omron probe x-frame set. But I do really like the Biqu MicroProbe. I bought an extra three of them a few months back when Biqu had them on sale for $15 each!

Haha same for me, I bought them for the 3 printers I have (one of them was for the ender clone I mentioned since I was going to convet it to a switchwire) and the one I installed so far 8s on my SP5, which has crashed 3 times already while printing and the pin was slightly bent so I was thinking about giving a try to klicky; but now looking at it I'm having second thoughts (I'm pretty sure the crashes were because I set the pint too fast withouth input shaping, although there are times I think the components dor the kinametics are just crap)

Hello, great design! Could I know the locations of the heat inserts? I was able to isolate a few locations after viewing a few posts. but I'm afraid to miss... Besides, with the "motor-bridge" and the 3-hole cable chain piece... what do I assemble the whole thing with?

Sorry, I wanted to make a new assembly guide but, with all of the different configurations, it seems like too large of a task. I made assembly instructions for the original four versions of the Mini Stealth that are still a little useful for the v2.

Here is a rather complete list of where heat-set inserts are used for the Mini Stealth v2:

• The only hotends that require heat-set inserts are the Bambu and the Dragonfly BMS models.
• Most of the extruders are secured with two inserts from below the core piece (1st pic) but a couple use M3 square nuts installed from the side of the core (2nd pic)
• Most of the x-carriages will use a pair of inserts from the back to secure the core (2nd pic)
• Most of the cable_doors will use one insert on the non-hinged side to secure it to the back side of the core
• A few cable_doors use two inserts on either side at the bottom and then hook under the top of the shroud
• The Omron probe (and Klicky) requires a pair of inserts in the retainer_bracket behind the x-frames
• Mounting a Beacon/Cartographer probe uses two inserts in the bottom of the x-frames
• The motor_bridge mounts for 2 or 3 hole cable chains will require inserts
• Mounting an umbilical PCB requires two inserts. Depending on which extruder is used, the last two images below show where to install them

Thank you very much for the time you give us. I would like to have more clarification on the assembly of these 2 pieces. I printed them for my needs, but I have some doubts about how. if there are heat inserts, or the size of the flat heads!lockquote widget

• Added support for HGX Lite extruder
• Added support for Creality K1 extruder
• Added support for Goliath hotend (CropTop only)
• Added 2.4/Trident x-frames for Goliath hotend
• Minor shroud geometry cleanup

Sorry, I didn't see your post before. The cable chain mount is secured with M2.5 screws straight into the plastic.

Would I need to re-print anything (better safe than sorry) if I had already printed the setup for my Voron 2.4 with a Rapido UHF and microprobe (haven't even started to build, though)?

The mesh cleanup was rather minimal so, as long as your prints came out well, you shouldn't need to reprint anything. The biggest fix was with that the old x-frame pairs (2.4/Trident/Switchwire) weren't aligned properly so the first layer could have had slicing issues. The rest of the update was adding compatibility for more extruders and hotends.

Hi! i was test fitting some parts before i get too far into my build and with the Galileo SA i noticed the extruder knob runs into the back of the standard shroud. is there a different shroud i should use, or a smaller extruder knob? I can confirm that it does fit without the knob.

If you want to keep the filament advance knob on the Galileo then you could use the Crop-Top version of the shroud.

According to the 3D data, the knob should have enough clearance to fit in the Knomi2 version of the shroud as well but I can't guarantee that it would spin freely while the extruder is feeding filament.

[Zeffer77]

okay, thank you for your help!
