Most 3D printer shops don’t touch firmware. We flash Klipper, configure pressure advance, tune input shaping, and rescue printers stuck on unsupported or poorly-built vendor firmware.
Our workshop runs the K2 range daily. Bracket vibration, bed-level calibration, extruder jams, CFS quirks — we’ve seen them all and written public guides to most of them.
Temperature towers, retraction tests, flow calibration, pressure advance tuning — done methodically, results saved to the printer’s profiles.
Unlike most 3D printer service outfits we don’t hide pricing behind a quote form. Here’s what the common jobs cost. Free diagnosis and no-fix-no-fee on every repair — you only pay for work that was actually done.
£40
Strip, deep-clean, calibration check and written report. Covers K2, Ender, Bambu, Prusa and most FDM printers. Free if you proceed with a repair.
£85
Flash Klipper, wire up the board, configure pressure advance and input shaping, run calibration test prints. Comes back tuned for your printer’s specific geometry.
£95
Belt tension, bearing replacement, extruder rebuild, hotend fit, fan and sensor replacements. Most mechanical faults fall in this tier.
£120
Diagnostic + mechanical rebuild + firmware calibration in one job. Printer comes back like new. Recommended for 18+ month old printers.
£65
Your printer is bricked or stuck on bad vendor firmware. Rollback, community firmware or Klipper port — whatever unblocks it.
£145
Component-level fault diagnosis and repair on the mainboard or toolhead PCB. Blown drivers, burnt connectors, dead regulators. Quoted individually if parts are unusual.
Resin printers, custom jobs, Voron builds and anything outside this list: individually quoted after free diagnosis.
Turnaround is typically 5–10 working days from arrival at the workshop to return dispatch. Parts-ordering for unusual printers can extend this; we’ll tell you up front.
Yes — they’re a workshop specialty. We’ve written a set of public K2 troubleshooting guides (extruder jams, bed levelling, retraction tuning) from our own experience with the printers on the bench.
Yes, on any printer where Klipper is supported. Includes config tuning for pressure advance, input shaping, and the printer’s specific bed / toolhead geometry. Flat rate £85.
Usually yes. We’ve done firmware rescues on plenty of printers where the shipped firmware was either buggy or removed useful features in an update. Options include rolling back, flashing community firmware, or porting Klipper.
See the pricing card above for full flat rates: diagnostic & clean £40, Klipper install & tune £85, mechanical rebuild £95, full service & tune £120, firmware rescue £65, board-level repair £145. Resin printers and unusual jobs are quoted individually.
Yes — LCD replacements, FEP film fitting, Z-axis alignment, mainboard issues. Send it in with the vat drained and cleaned.
Most jobs turn around in 5–10 working days. Parts-ordering for unusual printers can extend this; we’ll tell you up front if that’s likely.
Yes, 90 days on the specific work performed — including firmware configuration, which we document so you can see what was changed.
