Nice to have you back. I almost thought we lost you. ^^
And here we go again, not reading messages…
You stated that there are some magical movement limits when there are no limit switches. I explained why it’s doing that and that there are ways to overcome that issue, but they might limit the build volume.
Interestingly, you know everything but how to print with this printer, like other most people in this forum. These are not the same stepper drivers as in your Ender or Creality. In the end, it’s only the BambuLab engineers who know what the hardware can and can’t do. And they are also the ones doing replacements when something like this goes wrong. It is highly unlikely that they did not test that. Again, I have been running 9 of them pretty much 24/7 without issues. I will let you know when something changes.
That’s BS; your choice of filament has nothing to do with the complexity of a part.
70A is generally complex to print, not only on these printers. You should not be running a soft TPU through a PTFE tube from the side of the printer but directly into the print head. I’ve been having good prints on 70A TPU, but if you can’t handle that, you could also go for a foaming TPU; that way, you can go even softer and get a nice matte finish.
You keep on bringing up issues that you did not mention before to justify your personal opinion. If you have an issue, open a topic. We’ll be more than happy to help all we can.
But since you apparently did not return the unit as you said and did not open other issues, you must be having some fun with it by now.
Sorry for my absence. I absolutely would have returned the printer but I was in the hospital post-seizure and missed the window.
Like I’ve already said, the problems lie almost entirely on the software side of things. And your assertion about the bambu engineers is definitely true, but they can’t change the rules of the world that magnets + coils=electricity.
Why is it interesting that I “know everything but how to print with these printers”? Especially if you say everyone else in the forums is the same way?
I’ve had better quality prints on plenty of printers, but this “easy” one has been anything but.
I’ve been fighting with simple flow test and 82A filament all morning. It flows all over when it purges but when the print starts, it just takes a huge ■■■■ and acts clogged. Try it all over again, same story.
I’ve adjusted z offsets, made plenty of prints with harder filament.
The fact is that an all-metal hotend is just worse for flexibles, add to that the extra long melt zone in these printers and you’ve got a recipe for failed prints.
Just think about it. It’s pretty thin liquid in that melt zone. If I grabbed water and pulled, would the rest of the water follow? You’re counting on surface tension to do a ton of work that it just ain’t up to
That’s my fault, I knew it had the all metal hotend, but the hype was so strong that I thought it must have been solved somehow.
I have heard nothing good about support, not even from huge bambu stans like yourself. Why would I bother trying? They couldn’t even get the web page for unboxing finished before shipping units, this company has its priorities way out of wack
I must have missed something, but “electricity=broken driver” is news to me.
There is also a difference between a stalled stepper and a backdriven stepper…
Nope, most of the people here have good experience with their printers. (Or at least try to understand a problem) But for some reason, you tell them they never printed something complex. You have no clue what they printed.
I still can’t wrap my head around that one. Is it like a love/hate relationship? Nobody pushed you to use that one.
It is hard to help if we don’t know more about your setup, but you should check your extruder for any debris. And try to run it directly into the printhead, without a PTFE tube. (Maybe just a 1-inch piece to isolate the filament from the PTFE couplings)
Why did you adjust the Z offset? If I had any problems there, I would first check and play with the first layer flow rate.
How fast are you going?
So, to sum that up, you did no research and just bought something because it is fast and has an app?
I recommend using the live chat to go through with quick questions.
They usually take a few days to respond to regular tickets, but they are pretty helpful once they do. Ligistic tickets are usually way quicker.
Come on, man, it’s not like the printer comes in a million pieces. should not be that hard to figure that out.
C’mon dude you’re doing exactly what you accused me of here. There’s lots of people just like you on the Internet saying it’s great and can do anything. Are you admitting that it’s bad for this?
No, but if you plan on printing a lot of TPU, it should be obvious to go with something other than an all-metal hotend. I did not have issues, but as I said, I don’t use a PTFE tube for sub 80A. Give it a try.
Tell you what, let’s share slicer profiles. Show me the error of my ways.
I’ll take the PTFE tube of out of the equation or whatever you suggest. Though I’ve found filaflex isn’t sticky the way you’re saying. It’s got a very nice matte finish on the roll. 95A shiny TPU does exactly what you’re saying tho
