I only used standard 1.75mm diameter ABS, ASA, PLA, and PETG filaments. I didn’t use any additive filament types. I thought the cold drawing process on H2C only cleaned the accumulated residue inside the nozzle, but I’ll try to see if it will unclog the nozzle. This clogging problem isn’t normal because I’ve been using the X1C for 2.5 years and have only experienced clogging 3 times in that time. Before printing, I usually use the standard print settings in Bambu Studio according to the filament type; apart from speed adjustments, I very rarely apply nozzle or build plate temperature changes of only 5 or 10 degrees.
I’m so glad you didn’t have any problems
These clogging problems are really wearing me down, and I can’t leave my H2C printer unattended while printing. I’ve corresponded with both Bambu Lab technical service and the distributor in my country numerous times; they only tried to help with general procedures, but the problem persists. The distributor in my country has opened a service request; I’m waiting to see what the outcome will be. Either my induction hotends or the toolhead are faulty. Because I would understand if this problem only occurred in one nozzle, but I’m experiencing this problem in all of them. However, the left hotend works perfectly and hasn’t clogged at all so far.
Do you still have the x1c? Just asking have you tried moving the same filament to your x1c to see if it happens on that one (moving before you even work on clog on the h2c)? Is the filament dry? Is it the same print file or different ones? I ask as I have had a set of bad g code that was driving me crazy trying to figure out why it kept happening. Please understand not trying to make your problem worse or give a bunch of bs but sometimes the solution can come from people just talking it out
Yes, my x1c printer is still working. I did a test print on the x1c with the same file and the same values and didn’t experience any problems. I always dry my filaments before use and store them in vacuum bags with silica gel to absorb moisture. I hope we both overcome these problems and continue to enjoy happy printing. 
Maybe a bad unit? I run all 6 at .04 24/7 for a couplemonths. Run sunlu, bambu, overture, jayco and a couple others, not a single issue so far (knock on wood).
1370 hours in mine and 0 clogs, a few filament break in tube (old pla), if i have to complain about anything in the H2C is the left nozzle leveling, had a support ticktet open by a month now and a swapped left eddy (same problem) and a full bed coming to swap, but i think the bed is not the problem, the right nozzle works like a charm.
Maybe you have a bad hotend, try if support send you a new one, thats not normal.
