Hey all,

I'm just checking here as a final ditch effort before buying an aftermarket chamber heater. My team got an H2D and got a couple prints out running the chamber heater at 65C and then suddenly mid print it just failed and hasn't worked since.

I've looked at port 28 on the MC board, although, I haven't taken apart the entire chamber heater module yet (with how involved it is, it doesn't look like it's worth the time). I was just wondering if anyone here has had any similar issues and if they had any quick(er) fixes.

Honestly it's rare that we'll ever be using the chamber heater (mainly PETG, PLA, and PPS) so it's not a top priority and as nice as it would be to have everything working, a chamber heater is only $75-120 whereas to take everything apart, deal with support, re-install, etc.. we're looking at absolute minimum 4 hours.

I guess the 2nd question is: has anyone run the H2D with an aftermarket heater? Any concerns with doing so?

Thank you all in advance, I do also have a ticket open in parallel but I figure it doesn't hurt to check with the community.

EDIT: forgot to include error codes:

HMS_0300-9000-0001-0004: Chamber heating failed. The speed of the heating fan is too low.

HMS_0300-9000-0001-0001: Chamber heating failed. The chamber heater may be failing to blow hot air.

HMS_0300-3600-0001-0001: Chamber heat circulation fan speed is too low or stopped. It may be stuck or the connector may not be plugged in properly.

I get all 3 when trying to use the chamber heater.

Also, running 1.03.00.00 firmware incase it's relevant.

Hey all, my engr group has shown interest in getting a 3D printer and I've been trying to get together a list of options that they can agree on and then propose to our manager. Our group does industrial (2D) printing so I'm thinking placeholder components, mockups, thingamajigs and doo-dads, maybe some permanent brackets for low load conditions, and some wetted components (would be PETG or PP). None of this would be for production, just for the RnD side.

The list I have so far is:

Bambu X2D, H2C or H2D

Prusa Core One +, Core One L or Prusa XL

Or the Elegoo Centauri Carbon 2

The materials we'd likely print are PLA, ABS/ASA, PETG, GFs and CFs, maybe TPU/PEBA, PP, PA, and maybe but I hope not PC or PPS.

I've had an ender 5pro and currently have the CC1. I've been told that $900 on a printer is a blip as far as price goes but the current sentiment with management is that if we're going to get one, then we want to get one that can do everything we want.

I don't think it's worth going all out on an H2C or C1L right off the bat. I'm kinda hoping we can just get something simple so people get can get used to what having a printer means.

My question to everyone is:
If your group has a printer, what did you guys go with and how has it worked for your group?
What would you prioritize if you were to buy another one?
How has multiple (in our case 8-11) people using the same printer been?

Are there any printers that I'm missing here that are sleepers? I've dodged Creality here just due to reputation and Qidi was tempting but community support seems limited.

Thank you all, I'll edit if there's any big pieces of info missing. @ Mods, apologies if this post isn't appropriate for AskEngineers, I wanted to get general engineer sided opinions rather than FDM sided ones so I figured here might be better.

Thanks!!
