V0.2 - Formbot Kit Build

V0.2 - Formbot Kit Build
Part 1 - Unboxing and cPIF Parts
Unboxed the Kit on my live stream last night - https://youtube.com/live/qOcGWsB79Wo


I hope to update the build log with subsequent stream VoDs, videos, and text updates on how it went if it proves to be of interest to others.

Full disclosure the kit was provided by Formbot for making content. I paid for shipping

I'll be building the kit as "stock" as possible and will not any issues I have in the process. I've bought a full extra hardware kit from Sparta3D so if any hardware is missing I can keep going. Same for fans and other things I've noted can have issues in other folks builds.

Fairly happy with the kit contents so far(not having built one before):
-$349 Starting Price
-Kirigami Bed Frame (Not full kit, no RGB LED, pcbs or wagos)
-BTT Pi V1.2 (Only V0 kit I know of with a default Pi alternative included...?)
-BTT SKR Pic
-CHC V6 Hotend (Upgradeable to Dragon/HF)
-Double Sided PEI Sheet
-Crimped Wiring Looms
-Moons Motors
-Stainless Steel Rails
-MIC6 Cast Aluminum Build Plate
-Polycarbonate Panels
-Gates Belts
-Vivedino 60W Silicone Bed Heater
-Stainless Steel Hardware
-Umbilical Board + Harness
-Makerbeam XL Extrusion
-Meanwell 150W PSU

cPIF Parts from Fabreeko came and are looking pretty nice. Thanks Will

If you have any specific questions about the kit LMK

Unboxed kit organized

I'll probably print up some small parts organizers or dividers for this parts bin so I don't have to fish hardware out of the bags.

I got a nice remnant from a friends kitchen renovation for building the frame

I think in Part 2 I'll cover prepping for the build. More organization, Frame Extrusion Identification, Rail Cleaning & Lubing, and Printed Part Cleanup.
Cheers

More Organization & Preparation​

Stream: https://youtube.com/live/DwD1Kb6cqqU


In the stream I walked through:

• Kit parts/features
  • Unboxing thoughts and impressions
• Tools
  • LTT Screwdriver
  • Lubricant and syringe
• Parts check
  • Kirigami Bed
  • Umbilical PCBs
• Organize screws
  • Modbot organizer
  • Extra Hardware???
• Extrusions
  • Identify and put together
• Printed parts
  • Check/file/sand mating faces
• Organize parts
  • Printed parts in bins
• Rails
  • Clean
  • Lubricate

LTT Screwdriver​

I picked up an LTT Screwdriver. I've been eying one for quite a while.

Lubricant & Syringe​

For lubricating the linear rails I've gone with some Super Lube PTFE grease which has an NGL1 rating.

For applying the lubricant I reused a little syringe that came in a car windshield crack repair kit I bought a while back. Yay for being a pack rat lol.

Parts Check​

From the unboxing I've found that pretty much everything that's supposed to be in the kit is present. In terms of the hardware all the packs of fasteners are present. But I'm not sure about the quantities just yet.

There are differences between the base Voron V0.2 BoM/Manual and what comes in the kit. There's Zero documentation for the Formbot kit so I've found I have to use a combination of the Voron Manual, GitHubs for the 2 Mods, and LDO documentation.

Kirigami Bed​

This kit includes the Kirigami bed frame. But this is NOT the full "Kit"

You will need make sure you have printed parts for the Kirigami bed.

Be sure to check out the Mod's GitHub for a list of the STLs.

You can buy an LDO Kirigami wiring kit from DFH as I have done.

Umbilical Mod​

The umbilical mod is a mod from the Voron team that breaks out all the wiring connections from the tool head into a single wiring harness via a small PCB on the tool head, and then a larger PCB on the back of the machine. The PCBs and harness that come with the kit look nice enough. The mod will require a number of printed parts that aren't in the base V0.2 printed parts guide.

Hardware Organization​

I decided to go ahead and print ModBot's Voron V0 Hardware Organizer. I printed it out of MatterHackers Build Series Orange PLA and MatterHackers Silky Silver PLA. The organizer seems way better than fishing hardware out of bags

There were 3 bags of hardware that weren't listed on the Voron BoM or the Formbot listing BoM they were:
M2x4 SHCS - Mounting the Kirigami Bed to rails
M2.5x8 SHCS - These seem to be for mounting the generic V6 CHC hotend (and any other Phaetus Dragon style hard mount hotends)
M3x6 FHCS - I'm still not quite sure what these are for...

I've also printed Steve Builds' hex organizer to use as a bit of a staging area for hardware and parts I'm using in a particular step

Extrusions​

The Extrusions profiles are Makerbeam XL. They seem to have been anodized/powder-coated after being cut, drilled and tapped meaning they're pretty much black all the way around which looks really nice.


All of the extrusions have their ends tapped. I measured and compared all of the extrusions and they all seemed to come out as between 199.997 and 200.003. So +- 3 thousands of a mm (3 microns) according to my calipers.

Printed Parts​

Next I went through and sorted all the printed parts based on the general part of the printer and where they're used in the kit.

• Frame/legs/rails
• Jigs/Fixtures/Misc
• Bed/Kirigami/Z
• Mini SB
• Motion/Motors/XY
• Electronics/Cable Management

Organizing Parts​

Similar to the printed parts I've organized the non-printed parts into bins based on assembly order and part of the printer. I'm keeping stuff I don't really need immediately off to the side on another little table.

I'm going for kinda FOR (First Order Retrievability) here. I want to know where everything is, be able to see it and grab it easily whenever I need it. That is opposed to having things in nested boxes/bags that I have to dig through to get the stuff I need.

Cleaning Rails​

This part honestly had me a bit nervous. I was worried about how important it was to have carriages that lightly and smoothly just flew across the rails.
I used a little Plano small tackle box to soak/clean the rails in 91% IPA. I then manually dried them with shop paper towels that don't leave fuzz on things and set them out to dry. I used the syringe I loaded up with PTFE grease to reapply the grease to the carriage bearings. I pressed the syringe against the back of the rail on one of the holes and pushed the grease out until it visibly started to come out of the gap between the rail and carriage.

Everything seemed to work out well. The carriages DON'T fly across the rail with Zero resistance. But I can feel that all of the bearings have grease on them and should be limiting the metal-on-metal contact. They move smoothly without any binding.

Following along- I just placed an order for a formbot 0.2 because I have an addiction now
