Failings i should expect for ender 5

[Martin_au]

I thought I'd replied to this thread, but apparently not.
For an Ender 5, I'd have:
High priority:
• Spare fans for both hotend and print fans.
• Spare thermistor/heater (or perhaps a full spare hotend that can be swapped in).
• Spare bowden tube clamps
• Spare bowden tube
• I'd also get an extension from the micro SD card slot to a full size SD card to avoid wear and tear on the micro SD card reader.
• Spare nozzles

Lower priority:
• Spare idler pulleys
• Spare wheels for the V-slot runners
• Bit of spare belt
• Spare Z-probe if using one. If not, a spare limit switch is cheap and may be worth keeping around.


There are still a few potential failure points - e.g., bed wiring. Whether you want a spare bed and wiring harness is very much up to you.
The idea is stuff that's easily damageable - particularly on the hotend/extruder has a direct replacement. Then just carry a few spares for other items that undergo wear and tear, but which will generally give a reasonable indication of failure so you have time to order a replacement. I normally order those when I'm placing orders for the critical replacement parts.

Second printer is a great option. Especially given that the cost of a bunch of spares can rapidly build up.
