Mini Stealth - Orbiter 2.0 v. 1.2.5

hmm this is heavy to print and I broke it when removing from plate as it has no stability as the middle part is very thin.

So I tried to modify it with a Part of your standard Led-Carrier to get more stability and get rid of the included support (I just cut and merged it within the slicer as I'm not that far enough to do it with blender.....omg it's so much different to other Cad-software). it's just printing......

That is probably a good idea and a better print orientation. My mind has been too spread out lately with too many different designs..

True, it is like using MS Paint instead of Photoshop. But when you get used to the tools it can be very powerful.

ok, looks fine so far, many many thanks!! Now have to try with barf itself (have to remove from current running stealth). When trying I saw that there's no hole for fixing the led carrier in place (but its there in your .blend)?

and that the Led-carrier could be longer by about 3mm to better fit in the lower guide

Next thing I'd like to ask if it would be possible to get the Heat inswerts in from the lower side up to the extruder so they can't be pulled out, when I look through by not so well glassed Eyes it should be possible to get the inserts in from the Part fan side with a flat soldering tip (and maybe a small cutout of the Part fan wall on the left side at back view like in the pic above)

That hole was a very early feature that I have never used. Once the logo diffuser is in, the LED carrier becomes a press fit.

I think I need to take a break from working on the Mini Stealth for a while as I have two disassembled printers that need some attention.

A new question has arisen. Due to the smaller dimensions of the Mini Stealth, the nozzle and bed of the V2 no longer fit together. It looks like the bed needs to be pushed back a bit. Left/Right cannot be changed.

Am I correct in my assumption? I'm just wondering if resetting the bed still fits with the KlickyNG arm or if it collides when printing is at the very back?

When I designed this to fit in my Trident I kept the nozzle as close to the stock position as possible. In this picture, the nozzle on the Mini Stealth sits 2mm higher than the Stealthburner but is at the same X and Y coordinates. I don't think the bed location needs to be adjusted.

I did move the recess for the Omron probe back by 3.3mm to allow me to rotate the hotend away from the LEDs. I guess this will affect the docking for the Klicky probe. Here is a picture showing the official x-frame pieces in pink.

I found a new problem. I can't move the MiniSB all the way to the left on the X axis on a V2. The top inner screw head of the left X axis bracket collides with the bottom curve of the EBB board. Would it be possible to put the EBB holder screws 5mm higher on your Umbilincal holder? The EBB should slide up enough to have air down.

I am working on it but the geometry is messy so it will take a bit longer.

I am actually moving the screws to the Orbiter down but it will have the same affect.

Thank you for taking care of the problem! I just put the EBB holes up in a hurry. Bore after bore, the previous ones closed. It works. There is now enough distance so that the EBB no longer touches the screw head. But that's more quick&dirty with MS 3DBuilder.

As a welcome side effect, the max. accelerations with the miniSB are much higher than with the standard one. Great work!

I had never heard of that software.. It looks pretty useful. Nice work in solving the problem!

I finished up my new version of the umbilical mount. I think it is worth keeping the old one for use in the V0.1/V0.2 but here is the raised version. The whole part will sit 5mm higher on the back of the stepper.

Yes great! Thanks! I will change to ur new version at the next maintenance and will be the first test print

Does the orbiter filament sensor fits with these parts?  I expect the shroud doesn't, but without it?

If you do the crop-top it should fit just fine. You probably won't be able to use the filament_release_lever but the filament latch would be fully accessible.

Beacon probe arrived today and fits the x-carriage well. pcb is about 0,5mm lower than the part cooling outlets.

measurements for mini-sb-rapido:

base to cooling outlets : 51mm

base to mounted beacon: 51,5mm

head of mounting screws 1,8mm so total mounted beacon mesures 53,3mm

Assuming the Rapido measures 54mm there should be a clearance of 2,5mm from the beacon measuring surface and total clearance of 0,7mm from the beacon screws to the printbed whith touching nozzle. Hope this is what it should be?

Oh great! That sounds good. But what I haven't read out now, does the beacon now fit without adjustment if a Rapido HF is installed?
How exactly does the beacon work and is it sensitive to this heat? Can the Beacon also be connected to an EBB36?

Do you know of a source for the beacon from Germany?

Your measurements match the 3D models I've found from the different suppliers. The Beacon probe .stl shows 2.6mm from the print surface so everything seems to line up close enough.

On their website they show the probe secured with flat head screws. That could give you a little more clearance above the build plate.

Too bad Beacon is not recommended for embedded magnets in bed or even magnet surfaces for PEI adhesion. But thanks for the info!

if you could find some time and your Printers are ready could you pls implement zip-tie openings in the x-frame left

on the back and side? this would enable a structured cabling from X-endstop Microswitch / Probes up to the EBB/Main wiring harness.... something like this:

That looks like a good idea and should be pretty easy to add. I'll start looking into where I could fit them. I had just figured that the wires could route to the inside to where the Omron capacitive probe normally fits (through the red sections) since the probe won't be there when using the Beacon.

It's amazing what more heat (260c) and %30 fan will do for this print. It came out great! I'm excited to get wiring. Printed on a Cr6 SE with Klipper

Looks great! I'm looking forward to seeing your Replicator finished up.

Will this work?

x_frame_Mini_Stealth_left_Beacon_zip-ties.stl

wow, exactly as I imagined, looks great, will print and report, many thanks!!

made a fast testprint of PETG in a bright colour for better view on the Prusa as the Voron is busy, tight fit for the 2,5 x 1mm zip-ties but goes through when pushing/pulling a little harder, positions are perfect from my point of view, I'm loving it!!

would be absolutely great if you could find a way of pullthrough heatsets for mounting the orbiter like the mount of the Mini-SB to the x-carriage, i already pulled out the inserts a little and can't really fix it more than "handwarm"
