After more than 240 print hours with the H2D, I will now attempt into multi-color printing with two nozzles. At the latest when the HT is here.
With my X1C, the hours were always decisive for me to simply replace the hotend assembly completely. Here I have almost 6000 hours and of course already changed the nozzle several times.
How am I supposed to see now how many print hours the left nozzle has? I’m not going to print with the left one all the time.
How do you solve this so far?
@SupportAssistant It would be great to show a statistic for the left and right nozzle additionally. That is certainly possible?
Mine is at 226(9 days, 10 hours)… I think that’s pretty difficult(could be and my assumption), as it’s asking the timer to turn off and on, switch, etc, every time a nozzle starts, stops, purges for each nozzle. It would be nice, yes! But could be a bit demanding, and it seems they’re having a hard enough time getting even the basic “2nd generation” things working, that they’ve implemented…
It’ll probably take them some time, is that can do this, but it’d be a nice little feature and tool…
I have now already exceeded the 300 hours with the right nozzle and recently got the AMS HT. I now test to use the left nozzle.
My problem is that I don’t have an indicator when I should replace the left nozzle. I don’t need an exact timer for every nozzle change. It would be enough if the time for both nozzles is added together for a 2 nozzle print. @SupportAssistant@BambuLab
Example: The starting point is 300 hours on the right side and 0 hours on the left side. A 2 hour print is started with both sides. After that, you have 302 hours on the right side and 2 hours on the left side.
While setting a reminder to replace the nozzle is a helpful suggestion, it may not always be accurate, as nozzle wear can vary depending on the type of filament used and other printing conditions.
The most reliable approach is to inspect the nozzle periodically. Compare the tip with a new one to spot signs of wear, and perform regular cold pulls to keep the interior clean.
This way, you can maximize the lifespan of your nozzles without replacing them more often than necessary.
This is a ridiculous concept you are asking. Bambu should not at all pander to this request. The time to replace your nozzle is at the time you notice prints suffering. Pretty simple hey.
Well, I wouldn’t call it ridiculous. It is only through people who think differently that inventions and improvements have been advanced.
I didn’t even think about the fact that someone changes his nozzle depending on the material. It could have been a solution that can be switched on when necessary and that resets itself when nozzle exchange is detected.
If there is simply no counting method, then I have to think of something myself. I just don’t want to get into the situation that my nozzle is so worn out that I notice the change through a print. I don’t want to remove the well-fitting nozzle for a self-check.
I just replace the nozzle after 1000-1500 hours and that’s it. One less problem. For me, this is part of the device maintenance. Thanks anyway for your answers
There are more important things in life you can worry about than nozzle hours. Replacement nozzles are ridiculously cheap, just change it when the wind turns and get on with life.
There’s no point of tracking the nozzle hours.
The wearout highly depends on what you’re printing. Some of them can chew out a hardened steel nozzle within 2-3 rolls, some of them can do it in ~10 rolls, some of them would almost work fine forever like basic PLA or PETGs.
And people might have specific nozzles for specific print jobs. How do you track it when you switch to a nozzle for PPA/PPS, another nozzle for PETG/PLA, another nozzle for normal CF/GF and another nozzle for 0.2mm?
Again, there’s no point of doing it for every xxx hours. What matters is the rolls of abrasive filaments count. If you insist tracking this, I would suggest simply print a nozzle box, tag and categorize each type of filament you print with these nozzles, count the roll refills for abrasive filaments for each nozzle. I have a box for categorizing haha but I don’t count the rolls, I simply eyeball it ;p
Sorry I was unclear - I wasn’t trying to say that you had said to the contrary, I was just sharing the reasons I would prefer diamond.
There are almost always going to be tradeoffs.
I’ve been using diamond nozzles in my Prusa printers for as long as they’ve been available and I haven’t ever damaged one - thousands of hours on several of them - but I can’t say that it can’t happen. Just because it hasn’t happened to me doesn’t mean you’re wrong, I’m just sharing my experience.
Personally I’m all for having options and would love to see ruby, carbide, and diamond nozzle options.
Oh for sure - I am sure there are reasons carbide would be the better option. Ultimatley having options is a good thing I think.
