Creality Space Pi Dryer Problem

Hi everyone,

I have a Creality Space Pi Dryer. I bought it 10 months ago and used it only a few times.

Three days ago, I set it for PLA drying, 48h. After about 55h, I got E4 error. I turned it off/on and it worked again, but after 1 hour the device completely died. No screen, no fan, nothing. Power is fine, I checked.

I opened a ticket with the shop and also talked with the Turkey distributor. They said they already contacted Creality Global and are waiting for reply.

Did anyone have the same problem?

Not the first time I’ve ever heard of the E4 error (Space Pi (Dual) filament debugging E4 error code - #3 by Chris.S_NZ) but completely dying, that’s a first !

When my dual had E4, it wouldn’t heat,but display still worked…support sent me a second - replacement circuit board under warranty, when i installed that it showed E2, which i managed to fix myself and sent support a detained description of how to resolve,

They were supposed to create a wiki from my supplied info..

Not sure if that ever happened or not..

When i was diagnosing the E4 with support, prior to replacement..

This was their instructions

Actually, the distributor said my device is second generation, not the first one. The first generation had this problem, and Creality fixed it in the second generation.
So he also doesn’t understand why my unit stopped working.
I watched a remove video, but it looks hard to repair. Now I’m just waiting for a replacement, since my device is less than one year old.

Hey guys,

So my old Space Pi is still under warranty, but I haven’t heard anything back yet. I didn’t want to wait around without printing, so I decided to grab the Space Pi Dual. It showed up this week.

While digging around online about the Dual, I saw a lot of people saying they couldn’t drop the humidity below 35%. To fix it, they put silica gel beads inside the machine, usually with a little printed container near the filament outlets. I printed the container earlier this week and ordered silica beads today. For now, I tossed a few 5 g silica packs inside the machine. That way they can soak up extra moisture and keep things dry. It’s actually working great — humidity is sitting around 24% now and the prints are super clean.

Couple of things I’m curious about, maybe you guys can share your experience:

  • Can the printed container cause any problems for the machine? Anyone tried this before?

  • Since the machine doesn’t have any humidity exhaust, the moisture just stays inside. I saw someone make a lid open/close mod for it — is that really needed?

  • My setup area doesn’t have the best air circulation. Temps can hit 28–29°C. I added a medium fan to the back top of the unit and managed to drop it by about 2°C. On my single-filament Space Pi, I think overheating is what caused my issue. To avoid the same problem with the dual, I’m thinking about adding a bottom cooling fan compartment. Worth it or not?

  • Biggest question: how long can I safely keep this thing running? Like after 48 hours straight, should I power it down and let it cool, or is it fine to just dry the filament and then shut it off? Any “best practices” here?

Appreciate any advice or tips, thanks!

I own my space PI ( SINGLE ) from 8 months now and I use it for not less than 100 hrs a week,I have many rolls of different filaments and often buy new and dry them when I open first time,never noticed any error.

Now I don’t know if I have a 1st or 2nd gen device,arrived 2 days ago my new space PI x4,bought because the PI with max 70°C it was not enough for some PAHT-CF or PPA-CF filaments.

Anyways hope you will solve it soon with creality support

On the no exhaust.. my space pi dual has 2 small holes in the flip lid which are the exhausts..

Which i plug via printed inserts if im leaving spools in it long term between use/drying.

The issues with long term use only seem to arise if the lid is not fully shut, I.e too much heat escaping, causing constant heating as opposed to heat/hold.

I print directly from my space pi dual..often..
