Creality Creator Knomi Hi: problems, parts and running costs

Checked: 2026-10-25

Summary

A 1.28-inch, 240x240 round toolhead display for the Creality Hi Combo that shows print status over 2.4 GHz Wi-Fi and requires Klipper. Owners report a recurring “Binding Printer” animation mid-print, a config file wiped by a printer firmware update, and unverified touchscreen claims. Running cost is electricity only, about $0.38-$1.14 per year at the rated 0.65 W, and it is a reasonable buy around $30-36 before tax and shipping. [1][2][6][8]

Common problems and fixes

“Binding Printer” animation returns mid-print — owners report the binding screen reappears periodically even after successful pairing, usually during a print (GitHub issue #6, filed February 10, 2026). Root cause, affected-unit count and a permanent fix are unconfirmed; check 2.4 GHz signal, local LAN access, printer IP and port, and restart status. Warranty differs by seller: Creality “Up to 12-Month” vs BIQU “180-days”. [6][2][3]
Printer firmware update can wipe the Knomi config — one Creality Hi owner upgraded to printer firmware 1.1.0.60 in December 2025 and got XS3002 on restart because Creator_Knomi_Hi_01.00.00.00.cfg had disappeared; re-uploading it from GitHub fixed the error. Back up the .cfg and macros before any update. [8][5]
Touchscreen claim is unverified — BIQU marketing calls the module a touchscreen, but BIGTREETECH documents setup and customization through a browser, and an open issue asks whether the front surface is touch-enabled. No touch-controller spec was found; do not buy it for touch input. [3][6][1]
Wi-Fi binding can fail or take 50-300 seconds — discovery probes Moonraker port 7125; a 5 GHz-only network cannot connect, and LAN isolation or firewall rules can block detection, with manual IP and port entry as the fallback. [1]
Factory GIF and macro mapping is incomplete — GitHub issues #3 and #4 concern gcode_macro.cfg placement and getting all factory GIFs to display; some animation transitions depend on printer-side macros rather than pairing alone. [1][6]
Small screen, not a full controller — the 1.28-inch, 240x240 display suits quick status glances; logs, queues and full control remain on the printer’s own touchscreen or browser UI. [1][7]

Parts and consumables

Complete Creator Knomi Hi module (Creality 4008030118 or BIQU 1040000080) — listed $32.39-$35.99 from Creality direct and $55.99 from BIQU (October 2026); replace as a whole if defective; no manufacturer-mandated replacement interval. [2][3][4]

Yearly running cost

No subscription or cloud service is required. At the rated 0.65 W, 8 h/day for 365 days is 1.898 kWh/year, about $0.38 at $0.20/kWh; left on 24 h/day it is 5.694 kWh/year, about $1.14. Those are calculations from the rated draw, not wall-meter measurements. Spread over three years, a $35.99 unit is about $12.00/year excluding shipping. No replacement-part prices were found. [1][2]

When it is a good buy

At $30-36 before tax and shipping it is a reasonable buy for a Creality Hi Combo owner who wants toolhead-level status and custom GIFs and can handle Klipper setup; at $37-45 delivered it is acceptable; above $55 delivered it is hard to justify for status alone. Creality’s multibuy tiers show $30.59 each for two, $28.79 each for four and $25.19 each for six, and small-accessory shipping is $8.99, so a single $35.99 unit lands near $44.98 before tax (or $41.38 at the $32.39 option). Alternatives: use the printer’s existing web UI at no cost; the Creality Hi Touch Screen Kit at $17.99 for touch-based operation; or the $79.00 K-Touch wireless controller for a larger interactive surface.
