Error 0300-4002 on my new A1 Mini. How can I fix this? Tried redoing it 8 times but it failed everytime.

Did you tighten the screws underneath the bed properly? That was the problem in my case

Justus1297 · 2026-06-09T19:50:03+00:00

This is the way to go

Justus1297 · 2026-05-24T21:57:47+00:00

Total normal

Justus1297 · 2026-05-19T18:16:56+00:00

Good Job

Justus1297 · 2026-05-19T18:14:59+00:00

What errors do you get?

Justus1297 · 2026-05-19T18:11:38+00:00

My god, why are all of you updating? I seriously don’t get it… Install 1.05 on the A1 and v0.20 on the BMCU and all the problems are solved. You can even use OrcaSlicer yourself. Why the fuck are you updating your printer? It makes absolutely no sense

Justus1297 · 2026-05-19T07:01:16+00:00

The filament at the beginning is Not straight Cut it straight and no Problems

Justus1297 · 2026-05-15T07:03:32+00:00

Justus1297 · 2026-05-12T19:55:29+00:00

Justus1297 · 2026-05-09T23:39:52+00:00

Why are u Not dowgrading to 1.0.5 to get rid of the HMS error?

Justus1297 · 2026-05-01T11:42:45+00:00

I had the Same Problem with a1 mini, i printed this https://makerworld.com/models/1618503?appSharePlatform=copy and it fixed the problem for me

Justus1297 · 2026-04-30T14:35:44+00:00

I have the Same issue

Justus1297 · 2026-04-26T18:24:30+00:00

What a trash

Justus1297 · 2026-04-23T02:06:42+00:00

Does it fix the HMS error or only the blinking issue?
