-
Axminster
3 entries- AP2920B Bandsaw blades keep snapping or breaking, sometimes within minutes of fitting a new one
- AP340PD The drill bit visibly wobbles or runs noticeably out of true while spinning, instead of turning dead straight
- AW106PT2 Planer/jointer hums loudly at switch-on but won't start, trips the breaker after a few seconds
-
Bambu Lab
5 entries- P1P Printer is on and idle but the toolhead won't move on the direction buttons, or the nozzle and bed both read 0°C, or both happen together
- X1 Carbon "The cutter is stuck" error pops up on screen during printing, usually when the printer unloads or switches filament with the AMS
- P1S Heatbed temperature does not rise during print preparation, or the bed simply never heats after a bed temperature is set
- A1 Mini Print stops part-way and the printer reports 'The nozzle temperature is abnormal, the sensor may be open circuit' with HMS code 0300-0200-0001-0007
- A1 Printer shows 'printing' state in the app and on the display with no job running; won't accept new jobs until power-cycled

DeWalt
6 entries- DW733 Thicknesser cuts out mid-job and the switch won't restart the motor until you find and press a reset button
- DCD776 The drill switches itself off mid-job with no warning and won't run again straight away
- DCN660 The nailer won't drive fasteners — the trigger does nothing, or it fires the motor but no nail comes out
- DWS780 The blade carries on spinning for longer than usual after the trigger is released, instead of being stopped quickly by the saw's automatic electric brake
- DWS774 Mitre saw cuts are out of square — 90° cuts show a visible gap against a square, and mitred frames won't close up
- DCF887 Impact driver no longer holds bits securely — bits wobble, slip, or drop out of the chuck mid-job

9 entries- GE-BC 43 AS The petrol engine won't start at all, even after repeated pulls on the starter cord
- GC-PC 1335/1 I The guide bar and chain run dry during cutting and get noticeably hot, even though the saw starts and runs normally
- GC-PM 52/2 S HW The mower runs but vibrates intensively and doesn't operate smoothly, rather than running with its normal steady shake
- GC-MT 2236 The star-type hoes turn weakly or stop rotating altogether under load, even though the engine runs normally
- GC-CH 18/40 Li The hedge trimmer won't run, or the cutters stop the moment you shift your grip, even though the battery shows charge

- GP-LC 36/40 Li BL The chainsaw won't run at all when the trigger's pulled, or it starts then cuts in and out
- GE-CM 36 Li The mower won't start at all — nothing happens when the switching bar is squeezed

-

- K2 Water drips or leaks from the underside of the housing, including when the machine is switched off, sometimes alongside the motor not stopping when the trigger is released

-

Numatic
2 entries- GVE370 George is part-way through a wet pickup and suddenly stops drawing up water — the motor note changes pitch, and running the hose over wet ground or carpet does nothing more
- HVR200 Henry vacuum suddenly cuts out mid-clean and won't switch back on, even though it was working normally moments before
-
Prusa
4 entries- CORE One Printer stops during homing with "Failed to home the Y-axis. Make sure there is no obstacle on the Y-axis." and error code #31305
- MK4 Printer stops during Z-axis homing with "Failed to home the extruder in Z-axis, make sure the loadcell is working" and error code #13301
- MINI Printer stops during the initial preheat with "Preheat error print head" and error code #12202, before the print begins
- MK3S Print aborts partway through with a THERMAL RUNAWAY error, usually right as the part-cooling fan spins up, even though the hotend was heating perfectly moments before
-
Record Power
9 entries- Regent The tailstock shifts along the bed under pressure while turning, or the tailstock or tool rest holder won't lock securely onto the bed at all
- Envoy The turning tool suddenly digs into the spinning workpiece or gets grabbed by it, rather than cutting smoothly
- DML250 The DML250 mini lathe vibrates or shakes noticeably while turning, rather than running smoothly
- CL4 The lathe stops mid-turn and the main spindle bearing is locked solid, with no give when turned by hand
- DML305 Turned spindles come off the lathe with a visible spiral or thread-like ridge running along them, instead of a smooth surface
- PT260 The PT260 won't start at all — the motor doesn't run when the switch is pressed, in either planing or thicknessing mode
- CL2 The lathe stops during turning and the main spindle bearing is locked solid, refusing to turn
- CL3 Too much play in the headstock spindle, with vibration that makes the lathe difficult to turn on
- BS250 Bandsaw cuts wander away from the fence — the blade drifts sideways through the cut no matter how carefully the wood is fed

Triton
8 entries- TPL180 The planer's motor runs when switched on, but the blade barrel doesn't turn and the tool doesn't cut
- TJS001 The jigsaw loses power partway through a cut, cuts intermittently, or you can see sparking through the motor vents
- TSPST450 Sanding drum doesn't reach full speed, or the motor sounds different from normal
- TBJ001 The biscuit jointer bogs down or loses power partway through a cut, rather than cutting cleanly through to the end
- TWX7RT001 The router table module has no function at all when switched on — nothing happens
- TWX7CS002 Cuts made on the TWX7CS002 contractor saw module don't match the angle or measurement set on the gauges — mitres come out slightly off, bevels aren't quite true to the gauge, or rip widths drift along the length of the cut
- TRA001 Router won't wind up and down smoothly under a table — the winder handle feels heavy or jams, and the body drops a few millimetres the moment the plunge lock is released
- TPT125 Thicknesser motor sparks heavily at the brushes, loses power under load, and smells of ozone
