K1 Max 2 CFS
personally I have a BAMBU X1C
Work we have:
1-X1C
2-X1E
1-Fortus 450 III, Material Dryer and wash tank (Honeywell donated)
Just Ordered BAMBU H2C
Wow.
Definitely not my experience.
I like my P1S a lot. It is very much plug and play.
I’ve purposely isolated it from the innerweb to keep it from updating firmware, blocking access from most 3rd party applications/addons.
The only material I use anymore is ABS. PLA was fine, PETG and I agreed to disagree, and ABS just works.
cheers
We get the new H2C today
I just got in a spool of Sunlu PC-ABS I will be trying today on the X1E.
I have Stratasys PC-ABS, I have a part I need to run Bambu prints in 9 hrs, Fortus 450 21hrs
Sunlu $40 buck 1K spool, Stratasys 92 cu.in. canister $227 edu price, $454 comercial. crazy.
So this is disappointing. I started a 36 hour print. It looks like the firmware locked up fairly early, but the printer continued running. At the 24 hour mark it ran out of filament, and won’t respond. No out of filament error, just a stopped printer that is holding temp and doing nothing else. That’s $50 down the drain.
Overall my impression of this printer is Meh. I think value / $ this is equal to the Bambu. It is less expensive, but the quality of the prints is slightly lower, and the quality of the machine is also lower.

on my K1 Max, CFS and printer doesn’t work properly unless I power them on at the same time.
It should notice filament out, stop and allow you to replace spool and continue. Or use another spool in CFS.
That is what I expected to happen, but the printer is unresponsive.
I had mixed experience with Creality in the past. They seem to have way too many projects going on at the same time. They want to occupy every niche…
We have 8 Bambulabs at the office working beautifully but I like underdogs so I ordered an Elegoo Centauri Carbon!
We’ll see…

Bambu Lab is more appliance.
All other are different level hobby, builder.
Creality need a few mods. CFS is not plug and play.
I am having fairly consistent retraction errors at the end of the print. The best I can tell these are false alarms.
The bowden tube bend is too tight in the wire chain.
Also extruder do over heat and cause random stop and error.

The more I use the Creality, the more disappointed I become. I bought the large frame printer to make large parts. Every time a print fails, it costs me a spool of material. At this rate, I would have paid for the difference in cost between this machine and a Bambu in less than a year.
Yes, they’re different class.
Took me a month to get CFS working. No where in instruction say CFS and printer need to turn on at the same time to communicate.
My CFS is powered by the printer (K2 Pro) so that isn’t an issue.
Last night it ran out of filament, but didn’t detect that it was out, so it printed air for 8 hours.
I had a bunch of CR-10s back in the day. I was hoping the new printer designed to compete with Bambu would be of similar quality to the Bambu, but I didn’t do enough research before making the purchase.
There are things I don’t like about the walled garden approach of Bambu, but those issues don’t out weigh reliability issues.

Strange. CFS and extruder has filament sensor and both didn’t trip.
One function of CFS is continue on another spool.
Haven’t try that yet.
Did the blue light on extruder stay on even without filament?
I’ve had it successfully switch spools in the past. I’m not sure why it failed this time.
I can’t speak to the blue light. When I woke up and saw it was printing air I just turned it off and called it bad names.

Maybe bad sensor or something (broken filament) stuck and keep triggering the sensor.
This is what I see at the end of the last few successful prints. (They have all been 10+ hour prints, so overheating is a real possibility.
In addition to the failure to retract, I’m confused by the fact that the bar says 100%, the layers show 100%, but the time remaining shows 49 minutes.
Looks like K2 got a fan blowing on the extruder stepper. See if the fan is running.
Remove extruder and check if anything in the extruder.
F this stupid printer. I’m buying another bambu.
Anyone local to NC who wants a large printer hit me up. I’ll make you a heck of a deal.
I’m pretty sure the filament detector has failed high. That would explain why it doesn’t change filament when the spool runs out, and also explains why at the end of the print it doesn’t detect that the filament is retracted.
Years ago I had several Creality CR-10s. They were finicky, but that was the state of the art at that time, and they were relatively inexpensive. For the cost of this machine, I thought I was buying an appliance, not a science project. Very disappointed. So is the customer who thought I was going to deliver a finished part on Monday, but instead all I can deliver are excuses.
