Hi All,
Ive been having issues with my filament track switch and hoping someone may be able to help.
Long story short (I hope), I have 2x AMS Pro. 1x AMS is mapped to Input A and is supposed to flow to Output A (left nozzle) and conversely the other AMS is mapped to Input B, flowing to Output B (right nozzle). I will set it exactly like that in Bambu Studio slicer, however it will more times than not, Input A will head out of Output B and try to load into the right nozzle when the slicer is telling it to use the left nozzle of Output A. I donāt know why it keeps doing this I have also noticed that if there is a power outage, the mapped settings are lost and I need to set it up again. Iāve also noticed that if there is a filament change, then itās also hit and miss on if the filament goes to the correct nozzle.
My H2C was initially a H2D (upgraded via Vortek), running the latest stable firmware, along with the latest version of Bambu Studio.
Can anyone help or please point me in the right direction?
There is really no point in micromanaging the filament mapping when you have a FTS installed, its entire purpose is so you can just forget about where your filament rolls are loaded.
Could you explain why you must have filament going to a specific nozzle and what problem it causes if filament from AMS A goes to output B instead of A?
Iām running in to the exact same issue. I let the slicer figure out how it wanted to sort filament. Iām now getting a failure to feed error as it tries to feed the filament to the wrong nozzle and is getting blocked by the filament that is already loaded in to that nozzle.
Iāve also had a filament just get sent to the wrong nozzle even if there is only one filament loaded.
Bambu has already sent out a new switch so this is definitely a software issue they need to fix.
Hi Erikt1,
Appreciate the reply.
I whole heartedly agree with you. I dont care where it goes, though if I am doing multi-colour, I do want it to go through the right nozzle as that is where my 6 vortex nozzles are. In saying that however, unless I am doing something wrong, my H2C asks me to map it left and right. The slicer (from my understanding) determines which nozzle - which as mentioned, is sometimes needed for me and its that part of it (me stating where I want it to go) that does not work for me
The underlying problem is that if I do multi-colour to the right nozzle and the slicer tells it to use the right nozzle and it does what it keeps on doing by sending it to the left nozzle, then the filament will not actually āloadā into the extruder. It keeps tell me that there is a mismatch on the FTS setup and it will stop the print. This however (technically speaking) is not the case. Itās setup correctly, it (the printer) is just not doing what I (the slicer) am telling it to do.
Can you let me know if this works for you? Iāve got 2x switches (1 to be used in the future as I want 4x AMS Proās setup) and I tested both and both seem to have the same issue. I thought I was doing something wrong but perhaps not?
I will give it test later on today and confirm. Itās nearly 2am where I am, so time for bed.
I appreciate the reply and will confirm in a few hours as I do have some prints that I need to complete.
Thanks again!
For example, Iām doing a print on my H2C right now thatās single color PETG and uses support for PLA/PETG as an interface.
My left nozzle is a 0.6mm HF, the Vortek nozzle is regular 0.6mm.
For some truly baffling reason, by default Slicer wants the left extruder to do both materials. When manually split the nozzles, thereās a 5 minute difference between having the main material on the left and support on the right, or vice versa.
Wouldnt the HF versus regular nozzle account for the 5 minute difference as the support material is only like 2 layers on top of the support structure?
the non-splitting is interesting, perhaps the slicer thinks everything will be faster due to the left nozzle being a HF nozzle? The feature is quite new, and im thinking the choice engine in bambu studio is still kinda immature (or crap if you will).
You can only use 1 switch per printer. Its function is related to the inputs on the printer, not the AMS units. If you want to connect more then one AMS per input, you need 4-in-1 adapters. I think this is one of the more common misconceptions of this thing.
So I can confirm that the FTS does show in devices with no firmware updates available for it and I normally use custom mode (at least when using the right nozzle) with multi-colour prints.
Iāve logged a ticket with Support hopping to get traction. They did mention they are testing on their side and that PTFE tube resistance could be issue. Apparently the FTS will try another nozzle if the resistance is too high.
What doesnt make sense to me is why it will lose settings when I power off the printer and why will it change nozzles during a filament change? I appreciate that it will try another nozzle if the resistance is too high, but its already printing prior to changing filament, so surely the resistance isnt too high if the print has already started?
Strange, when I had some routing issues I only got resistance reports from the AMS units - the printer would say something like āAMS X reports high filament resistanceā, but then again I have never experienced it being so high it actually errored in any way, only got warnings.
Not saying its related to your issues, but if printing more then one filament, sometimes it does left/right nozzle swaps for one filament in different parts of the print depending on how other filaments are used. Not exactly sure its more efficient, but apparently bambu studio thinks so.
I keep having an issue where custom slicing sends the filament to the wrong nozzle, specially when done on the app. Now I ONLY use the filament saving profile and stopped having this issue.
I think there is a software bug that I have no clue how to report in the programing where it doesnāt always send the filament to a custom path.
I have also noticed that if there is a power outage, the mapped settings are lost and I need to set it up again. Iāve also noticed that if there is a filament change, then itās also hit and miss on if the filament goes to the correct nozzle.
