HMS 07FE-A000-0002-0001 means the left nozzle cold pull timed out, and asks you to click retry and then remove the filament. The machine was trying to pull a plug of softened filament out of the melt zone and the plug did not come.
A cold pull works because filament at the right temperature grips what is stuck above it and brings it out. Too hot and it stretches; too cold and it snaps.
Where to buy
Use filament made for the job
Dedicated cleaning filament is formulated to stay tough through the pull temperature instead of stretching like PLA or snapping like PETG. It is sold in short sticks because that is all one cleaning takes.
Have a nozzle ready to swap
If three pulls do not clear it, replacing the nozzle assembly is faster and more certain than a fourth. A hardened steel nozzle also survives the abrasive filaments that caused the blockage in the first place.
Work hot without burning yourself
Heat-resistant gloves are the difference between doing this properly and doing it quickly. A cold pull is a two-handed job performed next to a block at 200 degrees.
Then retry at the temperature the machine asks for
Let it reheat fully between attempts and follow the prompt rather than improvising. Three clean attempts tell you more than ten rushed ones.
How HMS 07FE-A000-0002-0001 differs from a switching jam
Debris blocking the switch mechanism is HMS 07FE-8000-0001-0001. A cold pull timeout is about the melt zone specifically.
What leads into it
A stub left behind after a runout is a common cause, which is HMS 07FE-7000-0002-0003. Technique is in clearing a clogged nozzle and material choice in brass versus hardened steel.
HMS 07FE-A000-0002-0001 FAQ
How many retries are reasonable?
Three. After that, change the nozzle.
Can I use PLA for a cold pull?
It works sometimes. Cleaning filament works more often.
Why the left nozzle specifically?
Because that is the one it was working on. Either can report it.
Does this damage anything?
No, but repeated hard pulls can unseat the nozzle.
Heat is worth measuring rather than trusting. HMS 0700-8000-0001-0004 means AMS heater 1 is heating abnormally, which means either the heater or its sensor is lying about the temperature.
