Voron recommends 60-70% (0.6-0.7) to start I chose 65%. Increase as needed but try to stay below 80-90%
Run Current = rated_motor_current x 0.707 x 0.65
Plug the max currents above into the equation with your desired percentage
- A/B - 0.65 x 0.707 x 1.5A = 0.69 (NICE!)
- Z - 0.65 x 0.707 x 0.65A = 0.3A

- Check Klipper docs for the correct sensor type based on your thermistor/hotend
All of the extrusions in the Formbot V0 kit are tapped on both ends. This means that using the V0 Manual extrusion identification diagrams can be a bit confusing. For 4 sets of extrusions where the manual differentiates them by tapped ends, you can consider those extrusions to be identical.
- A/B
- C/H
No drop nuts are very helpful for preventing preloaded M3 Hex Nuts from sliding around or falling out of the frame during assembly. They also allow you to pre align the nuts and hold them in place while you attatch parts to the frame.
The Formbot Extrusions are NOT MakerBeamXL profiles. They are closer to LDO's 1515 Extrusion. As such the no drop hex nut mods designed for LDO's kits work well with the Formbot kit.
Above: Left - Formbot Extrusion, Right - LDO Extrusion
I used them and found them very helpful. One big thing to note is that using the normal no drop nuts for the magnetic door latch can cause an issue. The spacing for these printed parts is such that using no drop carriers will cause them to be too far apart.
I used normal no drop nuts for these and had to essentially break apart the nut carriers to have them align with magnetic door latch parts.
There is a specific version of the No Drop Nut that is designed to be used here:

Remixed Formbot V0.2 Kirigami Frame Nutblock By @manisto: https://www.printables.com/model/837960-kirigami-bed-nut-block-for-voron-v02
Remixed Formbot V0.2 Kirigami Frame Chain Mount: User Deleted. Need New Model
The Formbot kit only comes with the Kirigami Frame. There's no LED/PCBs/Wago connectors, etc... included with the kit. You can source these yourself, find a partial wiring kit that includes them, or just leave them out and hard wire the bed components. See my My Mods section for the kit I bought.
The Kirigami bed frame is a great mod/upgarde that comes with the kit. It replaces multipe extrusions and printed pieces with a single rigid bed frame. The LDO Docs and Kirigami manual by Kagee provide some great info on general installation of the bed.
I had some trouble with the provided bed. I was able to get through all the issues with small DIY fixes. Other people have also noted they've run into these issues on the Voron Discord as well as the Kirigami GitHub. YMMV
- Frame Thickness
- My frame measured about 2.3-2.5mm
- I think this is due to the thickness of the paint on the frame
- Spec is 2mm, max tolerance of 0.2mm
- Caused the frame to not fit the printed Kirigami "stealth" Parts
- Stealth Nut Block
- Steath Chain Mount
- Can file the gaps in these parts or modify them in CAD and reprint if they don't fit
- Can also use some of the legacy non stealth parts
- My frame measured about 2.3-2.5mm
For the chain mount Voron Discord/Printables user Tommy Vercetti remixed the part so it fits well on the Formbot frame
GitHub Issue: christophmuellerorg/voron_0_kirigami_bed#16
- Frame holes
- Again likely due to the thickness of the paint
- Caused some slight over constraining of the frame when attached to the Z carriages
- My mounting screws barely fit through the holes
- No wiggle room to allow the frame and carriages to self align in a well enough that the frame and carriages would fall under their own weight
- Didn't completely bind the frame movement
- Just wasn't as smooth/free as after fixing
- Compounded with the frame not fitting in the nut block well
- Solved by filing out the holes in the frame
- This reduced the constaining and allowed the bed to fall easily
Non Stealth (Left) and Filed Stealth Nutblock (Right)
- Thermal Fuse Location
- When I went to adjust the bed screws so they bed was just close enough to the nozzle I couldn't get the bed springs to compress enough
- The thermal fuse was running into the frame
- I could have reduced the Max Z so the bed wouldn't come up as high after homing
- But didn't want to lose any Z height
- Solved by filing away a tiny bit of material on the frame where the fuse was interferring
There are mounting slots in the Kirigami frame that allows forward/backward movement of the bed screws. The LDO Docs include a link to a set of spacers that allow locking the heated bed in the forwardmost or rear most position.
Position these such that the nozzle is able to reach the full extent of the front and back of the bed. For me that was with the bed towards the rear.

Flashing (From Pi without PC): https://docs.vorondesign.com/build/software/skrPico_klipper.html
The SKR Pico is a nice small footprint Main Board. It trades some IO/connectivity capability for its compact size. Ex: there's no input of the chamber thermistor that comes on the V0 Umbilical frame PCB. Also there's no extra fan ports to hook up fans for something like the Nevermore filter. An Extra MCU like the Klipper Expander would be necessary to get some of this IO back.
There's some new compile params for the RP2040 in Klipper MenuConfig. Here's what worked for me
- MCU: Raspberry Pi RP2040
- Bootloader Offset: No bootloader (for USB, 16Kib for Canbus)
- Flash chip: W25Q080 with CLKDIV 2
- Communication interface (USB)
- USB IDs: USB Serial number from CHIPID
- GPIO pins: Empty

- 12-24V Power terminal input
- 5V USB-C Power input
The BTT Pi V1.2 is a nice alternative to Raspberry branded Single-Board-Computers that have frequently shot up in price. It has some nice 3D Printing specific features and numerous ways to power it.
The BTT Pi uses the same images as the BBT CB1 compute module. You can follow instructions for installing it.
BTT has 2 versions of the Kernal. A Minimal image and a Klipper image. The Klipper image has Klipper, Mainsail, Crowsnest and most other dependencies pre-installed. They just need to be updated after. Images: https://github.com/bigtreetech/CB1/releases
By Default the host name for the image will be "btt-cb1" and it can be accessed with "btt-cb1.local" if you don't know the IP Address for it yet.
GitHub: GitHub: https://github.com/VoronDesign/Voron-Hardware/tree/master/V0-Umbilical
The V0 Umbilical is a great mod included in this kit. It makes wiring much easier. All of the signals/power to the toolhead goes through a toolhead PCB breakout board, down to the back of the frame via a pre-made wire harness, through a second frame pcb breakout board and finally down to the SKR Pico.
Formbot has precut and crimped most of the wires that go from the mainboard to the frame PCB. They've also made most of the wires that hook into the toolhead pCB the correct length as well.
Be sure to print the V0 Toolhead PCB mount and strain relief found here: https://github.com/VoronDesign/Voron-Hardware/tree/master/V0-Umbilical/STLs/V0.2
This is a general wiring diagram for a Formbot V0.2(r1) kit. The only thing specific to the V0.2r1 is the Filament Runout Sensor (FRS) which gets plugged into the E0 Endstop input on the SKR Pico (next to the RGB/Neopixel). Otherwise it should serve pretty well as a general V0.2 build.
Since the V0.2 uses sensorless homing on the X-Y/A-B axes there's no endstops plugged into either of those inputs. In fact it's important to ensure that nothing is plugged into these inputs. Otherwise sensorless homing will not work.
** Note: ** Use this wiring diagram as a guide, but be sure to follow the polarity from the SKR Pico all the way up to the Umbilical PCB and out of the Toolhead PCB. I highly recommend using a multimeter to check for continuity of the pos/neg at the board and toolhead PCB. Some fans or intermediate wires ** MAY ** be pinned backwards. If this is the case I suggest depinning the connector and swapping the wires to ensure the correct polarity is carried all the way up to the fans.
There is no polarity for thermistors or heaters!
The Formbot kit does NOT include any wago or inline connectors!
The Kirigami Bed Frame alows splitting the wiring coming out of the bed so that the bed can be removed and worked on without being tethered to the printer.
Voron recommends using Wago connectors to allow easily disconnecting the wires. The Kirigami bed mod includes mounts for the Wago connectors.
Since the Formbot kit bed heater doesn't include an integrated thermal fuse it needs to be connected inline with one side of the bed wires.
An inline connector can be used to split the Thermistor wires under the bed.
** NOTE: User [@Carlsans] (https://github.com/Carlsans) mentioned his Formbot kit came with a preinstalled [thermal fuse] (#3)
The LDO wiring kit includes 2 Wago mounts, a Thermistor breakout PCB and an LED PCB. A third wago is needed for the Formbot Thermal Fuse. The LDO V0 repo has stls for mounting its PCBs and the wagos. See the Kirigami Manual for more info.
Formbot provides a precut, pre-crimped wire harness to go from the BTT SKR Pico's top right pins over to the BTT Pi V1.2's VCC and GND GPIO Pins. It provides 2 5V wires and a single ground. I think these were design to work with an original Raspberry Pi 3/4 which has it's GPIO on the right.
Since the BTT Pi has it's GPIO on the left the only way to get the wires over to those pins I had to stretch them across both boards. I felt the looked bad and worried about the tension.
To solve this I used their JST connector and repinned/crimped the some longer wires with Dupont connectors on the opposite side. With the wires longer I can pas them under the edges of the boards and through the cable management channel in the middle
By default the Formbot kit connects the BTT Pi and SKR Pico by USB cable. This works well and is easily set up. However, it does limit the number of open USB ports to two (one is also taken up by the V0 Display). Since I also added a Klipper Exander and USB camera that meant all four ports were used. Leaving none for things like a USB Input Shaper Accelerometer.
Connecting the Pico and Pi via UART opens up a spare port again to help with this.
As noted in the section above the Formbot kit powers the the Pi via two +5V and a single GND set of wires going from a JST port on the SKR Pico to the GPIO Pins on the Pi. This is actually the UART comms header on the SKR Pico so we can easily add two wires (Green and Yellow in the Wiring Diagram) to free up the USB Port.
One end needs to be crimped with a JST XH connector and the other needs to be female duponts. Since this will only be transmitting data the guage isn't hugely important. You can use already crimped female-to-female Dupont bread board wires cut to size and crimped with a JST on one end. OR in my case take a pre-crimped JST wire and crimp a Dupont (harder to crimp) connector to the other end.
Then plug the extra two wires into the 5 pin JST connector housing on one end, and the Dupont connects onto the pins adjacent to the power pins on the Pi GPIO.
You'll need to shut down the Pi remove the SD Card, plug it into a computer and open the BoardEnv.txt file on the boot sector of the card. In that file change the line with console=and set it to console=serial to tell the Pi to talk via it's UART interface.
From there you can put reconfigure the Pico firmware to use UART0 GPIO1/GPIO0 for it's communication interface. Flash it via USB. Disconnect the USB and connect it via the new UART cable. Finally in your printer.cfg change the serial: portion of the MCU definition to /dev/ttyS0.
You should then be able to reboot the Pico and communication between the board and the Pi should work as normal
This is an optional upgrade on some Formbot listings. It offers single hand nozzle tightening and much higher Max Flow Rate compared to the default Formbot V6 CHC nozzle.
Ali - https://s.click.aliexpress.com/e/_DlBBu2d You have to buy all the parts separately...
This further increases the flow rate of the Dragon HF.

The stock fans are probably the most noticable lower quality parts of this kit. I found the plastic a bit brittle and the leads didn't tuck into the their slots on the body. This cause them to get pinched when I put them in the Mini SB.
I found using any type of ball end and some not very sharp edged hex/allen drivers or bits resulted in stripped screws. In particular on the Frame and rails screws which I ended up screwing and unscrewing numerous times.
I tried my RC style hex drivers which have noticably sharper corners and noticed I didn't have any stripped screws.
Most will probably work well. Fabreek sells a couple different sets

Printing ABS (as with most filament materials) can release VOCs (Volatile Organic Compounds) and has a noticabley more noxious smell than other materials like PLA. An active carbon filter can help clear absorb those orders/VOCs and move some air around the chamber for more efficient heating.

I thought it would be fun to modify the stock V0.2r1 FRS foot and use a smart sensor instead. With the use of a ball bearing and 2 push buttons the Orbiter sensor takes advantage of Klipper Macros to allow features like pausing/resuming, auto extruder heating, auto purging and quick unloading with the press of a button.

There's also jigs for spacing the Pulleys on the A/B Motor shafts which I found easier than the stock Voron tool
