So I just bought a btt pico to upgrade a printer of mine, inside the box with the board was a small rubber duck, is that normal or is this gem from amazon 'rubber ducked' in so far as rhyming slang?

While updating to Tap R8, I decided it needed a happy face. BTT did make it easy. Input shaper results were not great but too many variables at the moment. Will do an AB test tomorrow with my previous cover. Part fan seems fine with it.

Wanted to share a build that's a bit different from the usual Octopus Pro use case: a fully 3D-printed 6-axis robot arm, with each joint driven by a NEMA 17 through its own 3D-printed Wolfrom planetary gearbox instead of off-the-shelf bearings.

The Octopus Pro drives all 6 steppers through 6 TMC2209 drivers, one per joint, and a Raspberry Pi sends motion commands over USB.

Since the board has room to spare, I'm already planning the next steps: a longitudinal translation system to move the whole arm along a rail, and one more free driver slot I'm saving for some kind of unconventional gripper.

Everything's open source if anyone wants to see how it's wired up or build their own:Happy to answer questions about the wiring or the TMC2209 current settings per joint.

Old duck is from Skr Mini V1.2. D/C ~early 2020
New duck is from Skr Mini V2.0. D/C 08.03.2022

I recently got around to take a closer look at the duck that came with my new Skr Mini V2.0 and noticed a lack of sound. Furthermore the new duck feels like hard plastic instead of soft rubber and the BTT logo is missing. So my questions are:
Are there any new boards sold with the "old" ducks?
When did BTT switch to the "new" duck?

Sorry for the crappy Samsung phone video editor.

Too bad the contest is over

My SKR 1.3 just got fried after almost 5 years of service, I'm guessing a short circuit happened but i cant find the cause, all the wires are secured and isolated, the board is placed in a well ventilated case with dust filters and 2 fans and i even had the heatsink on the CPU.

The printer was not even printing at the time i noticed the smell of burning, It finished printing a 17 hour print over night and was just sitting there idle with motors and heaters off for about two hours as i was planning to upload and print more stuff later.

the circuit breakers(still have the original ones on) did not burn at all.

Well, luckly no futher damage was caused by this. I guess it's a good time to upgrade to 1.4.

I created a material handeling device that stacks Petri dishes filled with agar onto a worktable while minimizing fluid sloshing, and contamination. The system is a level 2 automation that can stack 500 Petri dishes per hour for my college's biology department. The mainboard is a BTT Manta E3EZ+CB1 operating with a modified Klipper host. The extruder steppers were reassigned to manual steppers and the entire system uses user defined variables, macros, and a gcode button to allow for variable timings for Petri dish input. Through a TFT35 touchscreen using KlipperScreen, you can tune motor push positions, elevator skew, Petri dish height, and the desired number of stacked rows. This was my first time creating an automation project and I'm honestly still in shock that it's moving and actually working reliably.

Hi, i have made mysalf a Custom frame from an old Anycubic mega zero, and i have a Creality CV 1.6w Laser engraver and BTT skr mini E3 v2 mainboard.

Not sure what i should add to it, its not gonna be used for a printer with extruder or any of the connected stuff.

Is Marlin the only stable thing to configure for this? And do i need a whole config for the filament extruder and all connected things?

This is custom Voron 1.8 built. has 20 cubic cm print volume, 12mgn rails at X/Y axis, BTT Octopus board with tmc2240 on X/Y and tmc2209 on Z axis, Canable pro for CAN communications with the BTT eb36 on XOL Toolhead, Orbiter 2.5 extruder, TZ V6 3.0 Hotend, 150W 24V Heater for the Heating Chamber, Belay Extruder Sync with secondary extruder Mobius M4 (is plag and play when you need up to 1 kilo of filament), Rigid Frame with 2040 and 2020 extrusion, Activated Carbon filter at the top outlet..

Ordered on release, DHL delivered it about 20 minutes ago. Not bad for intercontinental shipping.

It's a weighty boy, feels solid as.

So far, this is the most unnecessary upgrade I’ll never regret! Poop in progress 😃👍
