# Gyropup: build the first prototype
To order: **$6,587.17** from **52** sellers ( **260** lines, whole packs and spools) + **~$777.28** machined or cut to order (estimate) · **~520.2 h** of printing (8.74 kg) · **1** line still without a price.
Everything to order and to print for the first physical prototype: one leg on its single-leg test rig (milestone M3), the turret v0 on its bench stand, and the body's first open frame when its files exist. Generated from the repo's own data each time the page loads (the parts lists and print plans in `exports/`, the catalogue in `catalog/`, the plans' chosen sellers in `docs/`); nothing on it is typed by hand. Prices are the listed ones on the date shown, before shipping and tax.
**One leg (milestone M3)** FROM THE DATA
Leg v2: the hip frame, the links, two RS-04s and the BotWheel; qty for one leg. Plan: [docs/leg-prototype-plan.md 6.1](https://gyropup.com/site/pages/docs-leg-prototype-plan-md.html#61-bom-leg-per-leg-rig-electronics-primary-and-backup).
6 printed parts, ~195.4 h. bom.json's own figure: $1,125.32 per leg at catalogue prices, pieces used.

## Order on day 1: longest lead times first
What to order first, so nothing waits on it: lines that ship from China, are out of stock or backordered, are hard to buy, or are made to order, and any line whose data records a lead time of a week or more. A lead time is shown only where the data records one (a seller's stock line, the catalogue's price note, the made-to-order note), with where it came from.

CNC Kitchen's table gives the hole as 9.7 mm, against 9.6 mm in the CAD (0.1 mm larger). Length 12.7 mm matches. It will probably go into the existing 9.6 mm hole with slightly more interference, but that is not confirmed.

- CHANGES **OpenELAB** [DM-J10010L-2EC](https://openelab.com/products/damiao-brushless-servo-dm-j10010l) · $321.99 · Orderable; ships from China
Closest substitute (Damiao DM-J10010L-2EC): same 40 N·m rated / 120 N·m peak and 200 rpm no-load at 48 V, but rated output speed is 100 rpm at 48 V vs the RS-04's 167 rpm. Round body ~120 mm dia x 53 mm (RS-04 is 120 x 120 x 56 mm), 1.37 kg vs 1.42 kg, 10:1 vs 9:1. The output flange and mounting-hole patterns differ (page gives no hole pattern, so take it from Damiao's drawing), so the printed hip frame and the leg-link flange must be redrawn. Protocol changes from RobStride's CAN protocol to Damiao's CAN protocol (MIT, speed and position modes at 1 Mbps; UART at 921600 bps for setup), so the joint driver code must be rewritten. Supply is listed as 24-48 V (the RS-04 is 15-60 V), so check the pack's full-charge voltage. Connectors are the same types: XT30 power, GH1.25 CAN.

Same as the openelab DM-J10010L-2EC entry: new hip frame and flange, Damiao CAN protocol in place of RobStride's, 24-48 V supply, rated speed 100 rpm vs 167 rpm at 48 V.

- CHANGES **CubeMars** [AKE90-8 KV35](https://www.cubemars.com/product/ake90-8-kv35-quasi-direct-drive-actuator.html) · $483.90 (actuator only; driver board not included)
A stronger QDD (48 V, 55 N·m rated / 170 N·m peak, 120 rpm rated, 210 rpm no-load, 8:1), 1400 g, round 107.5 mm dia x 43.5 mm. CubeMars' comparison table lists 'Driver Board: No', so a separate driver (page downloads list an AK80-4830-1C-A4 driver; its price was not seen) must be bought, mounted and wired. That means a new hip frame and flange plus room for the driver, and CubeMars' CAN protocol in place of RobStride's in firmware. It costs about 1.9x the RS-04 before the driver.

Same maker and same RobStride CAN protocol, so firmware changes the least (motor type and limits only). But it has half the torque: 20 N·m rated / 60 N·m peak, 195 rpm no-load. It is 106 x 106 x 56 mm and 880 g, with flange holes listed as '30.35 x 9 x 6 mm (M4)' and installation holes '98 x 8 x 8 mm (M4)' (the RS-04 lists M5 '35.86 x 9 x 9' and M4 '106 x 10 x 6'), so the hip frame and flange must be redrawn. Only usable if the leg torque budget allows it or another reduction stage is added.

The mount changes completely. It has a single-sided cantilever axle with an M16x1.5 thread and 12 mm flats (43 mm long), held by a nut through a slotted plate, instead of the BotWheel flange taking 4 x M6 on a 36 mm circle, so the wheel mount at the foot of the leg must be redrawn. Tyre is 173 ±2 mm dia x 44 mm wide (BotWheel 171 mm), overall width 118.2 mm. Mass is 3.75 kg vs 2.2 kg, i.e. +1.55 kg at each leg tip, which eats into the leg torque budget and needs the balance controller retuned. It has a 4096-line encoder and 15 pole pairs (BotWheel: hall + 3200 CPR), and ZLTECH power and signal connectors instead of JST PUD, so the ODrive harness must be re-terminated and its encoder and pole-pair settings changed; the alternative is ZLTECH's ZLAC8015D driver, which needs different firmware. It is 24 V, 6 N·m rated / 18 N·m peak, 160 rpm rated, IP65.

Same Feetech STS serial-bus protocol and 3-pin TTL connector, so firmware stays the same apart from limits. It is stronger (50 kg·cm stall at 12 V, 345:1, 6-12 V) and costs about 2.6x. The page gives no case size or spline, and it says 'a matching TTL interface alone does not establish mechanical compatibility', so check the case and horn against the 45.2 x 24.7 x 35 mm STS3215 before reusing the turret brackets.

The case is 28.5 x 46.5 x 34 mm with a different horn and mounting holes, so the pan/tilt brackets must be redrawn. It speaks DYNAMIXEL protocol over TTL instead of Feetech STS, so the servo driver/SDK and ID setup change. It is weaker: the page gives an estimated rated torque of 0.28 N·m, against about 0.98 N·m (10 kg·cm) rated for the STS3215-C018. Only worth it if the turret load is light.

At 12 x 28 x 5 mm (3 g without motor wires) it is 2-3 mm longer than the Repeat board's 25-26 x 13 mm, so check the ESC pocket. It is rated 45 A continuous / 60 A burst, 2-6S, no BEC. The page lists DShot1200, Proshot, Oneshot125, Oneshot42 and Multishot input with auto-detect but does not list standard servo PWM, so confirm the controller's output protocol. It is not pre-tuned: set direction, bidirectional mode and throttle limits in the AM32 configurator. It ships with a 220 µF 35 V capacitor that needs a place in the wiring.

No board: lever connectors splice the 24 V feed (XT60 -> fuse -> switch -> DT12 plug power pins) and the pendant loop in free air. Drop the four M3 inserts and bosses for the 70 x 50 board (or keep them for a strain-relief plate), cable-tie the connectors to the floor or a printed cradle, and use 12-24 AWG wire. There is no screw-terminal board to service, and the pendant loop becomes two inline splices.

Board size not checked against the stand's 50 x 20 x 12 mm envelope, and it has several CAN outputs ('-3 CAN Output'). The listing is shared with the EBB boards, so pick the U2C variant. Firmware is BTT's candleLight fork (gs\_usb), so Linux gets can0 without slcand.

An enclosed dongle on a cable, not a board on the stand floor, so the back-wall USB-C slot and the 50 x 20 x 12 mm envelope do not apply. From general knowledge, not the page: it has a D-Sub 9 CAN connector, so it needs a DB9-to-wire lead, and it uses Linux's peak\_usb SocketCAN driver instead of gs\_usb or slcan. About 30 times the price of the UCAN.
