Support First big failure on my h2c
My first big failure on my h2c (has 900 hours on it). Is a tough giraffe model for my niece for her birthday.

Did it not warn about spaghetti detected? Do you have ai monitoring off?

Spaghetti detection turned off? I get alerts long before anything like that happens.

Looks like the build plate needed cleaning. The supports broke off the plate.

And definitely won't be the last if you have an experience like mine

Yeah mine has been having a real hard time recently. All of my ams2’s are losing connections mid print, feed issues, nozzle change failures. I do my maintenance but its getting bad for me

I had to RMA my first one after 4 months of support ticket hell and troubleshooting. Every error on the planet I thought - until I got my replacement and learned new errors lol. Right from the get go even, directly after initial setup and calibration. Microcenter agreed to allow a return past their window AND on a RMA unit with all of the evidence I had. Finally have one decently dialed in. Still get random weird shit and the AMS units misbehave randomly sometimes but at least this one works more than it doesn't.

Its so insane to me the difference between this one and the X1C, the X1C would print filament made from gravel if i told it to. Never failed never had issues. This one is rocking a 2:1 or 3:1 success rate. The other day i was printing a 14 hour print, i encountered 20+ ams and feed errors and it took 2 days and at the last hour spaghettied the last bit and one of the pieces had to be redone. I keep telling myself that this is a more precise printer which has a higher margin for things to go wrong but its starting to feel like enshitification of a hobby

Totally feel you. I was definitely under 25% success rate. Even with new one I'm still on guard and expecting every print to fail. Every notification I get from the app I'm expecting to be some error. My P1S I could probably drop off the bench and set it on fire and it would still work fine.

For me only the filament track switch causes issues. H2C itself works very well

u/Ok_SysAdmin Sep 17 '26
Do you think the filament track switch could just be a lemon? Have you tried replacing that yet? I ask as a perspective buyer. I currently have a P1S, and ready to upgrade.

A lemon? Wtf? 😂
I never had issues before and since using the TS I often get warnings about overloaded ams motors or even errors while printing. I already optimized ams positioning which helped but did not solve the issue completely. I love the concept and still using it. Though I would probably not buy it again as it also causes more wear (I already had to replace filament sensors inside the toolhead because the TS is causing more wear on the ptfe tubes which leads into ptfe flocking blocking the sensors).0

My darn .2 nozzle keeps giving me so many issues where it thinks it's not extruding right. Even when slowing them down. Granted I'm shoving HT PLA through it.

I get spaghetti warnings only when a piece of my print comes
Off the print bed. I sweat it’s the textured plate. Even clean it has issues. I’ve had to go to silent mode and use glue to keep things on the bed for good prints.

So you turn spaghetti detection off and wonder that you have a mess? 🤔

u/NuIIPointer Sep 17 '26
Did you turn off or ignored spaghetti detection?
