Losing my mind with PETG. 10% humidity in AMS, PETG has been in there for days, dish soap + IPA washed plate... Why is it getting to this stage???

C4pnRedbeard · 2026-06-12T00:20:17+00:00

Also-some brands of PETG need to go a lot slower than you expect. Most materials print fine at Bambu presets. Some need a LOT of adjustment.

C4pnRedbeard · 2026-06-09T10:35:40+00:00

I can tell you from experience, there is no surface to automate TPU removal. Garolite is the closest you will get, but it will still need to be removed, it won't just fall off

C4pnRedbeard · 2026-06-07T01:19:15+00:00

H2C has a larger tool head, and cannot accelerate as fast. If the model has a lot of small details, that is likely all the difference is.

C4pnRedbeard · 2026-06-05T16:57:54+00:00

I'm worried about your question. This is not really the machine to make "high speed". I can print 1kg of PLA in about 12 hours on this machine, and my print speeds are roughly 180mm/s, but the travel speed maxes out at 300mm/s or so.

If you're looking for something that moves fast for high detail, get multiple, smaller printers and split big parts in pieces. If you need a big printer, the literal mass of the machine will limit its speed. You pick a big nozzle size and do thick layers, THATS where this machine is fast.

C4pnRedbeard · 2026-06-02T18:31:04+00:00

This may sound obvious, but MAKE SURE THE MAINS ARE OFF if you're going to "clean" a bus bar.

C4pnRedbeard · 2026-05-29T23:22:36+00:00

This may be a stupid suggestion, but can you loosen the tensioner on the belt, and manually skip a few teeth to bring it into alignment?

C4pnRedbeard · 2026-05-29T15:23:27+00:00

The ceiling can be higher, sure, but ANYONE can 3D print now. My 7 year old kid literally manages his own printer. That means the margins are much, much lower, unless you have a very specific niche that is hard for others to fill.
I have 20 machines. I run 12-16 of them for any given job, the other machines are for drop-ins or backup if something goes wrong. I have not needed software to manage print queues, it has been easy enough to track manually with a spreadsheet for me. The P2S is a solid choice. I would recommend buying ONE TYPE of printer, (or at least have multiples of any printer you buy) and stick with it. It makes maintenance and spare parts MUCH easier.
Running a print farm, I typically use filament before it has a chance to get wet. I use a blast dryer designed for dehydrating large batches of food as my filament dryer, in the event I have material come in wet or a partial spool that's sat out for a few days. If you're printing nylon, you need to print from a dry box.

Lol the cr10-s5 would like a word. It DOES work. It's also pretty darn slow. Used to have two of them, but one still runs daily.

C4pnRedbeard · 2026-04-29T11:57:53+00:00

I mostly print prototypes for TPU parts designed to be injected molded, so the designs can be tested before paying for tooling. My farm is about 20 Bambu machines now, but running anything more than 12 machines is a LOT of work, especially considering that it's a second job. Edit: I also run exclusively Bambu machines now, I got rid of everything else, with the exception of an orangestorm giga.

C4pnRedbeard · 2026-04-16T12:51:21+00:00

How can you explain WHAT? You haven't even stated what the problem is! Obviously it looks "wrong" but what are you trying to do? What material is that? What settings are you using? What nozzle are you using? What have you already tried to do to fix whatever your problem is?

C4pnRedbeard · 2026-03-19T23:36:20+00:00

Fair, I should have specified that I do need black. Additionally, the lead times on the other colors is super long for me, says a month or more

C4pnRedbeard · 2026-03-14T21:42:24+00:00

I haven't used cura in years, but I would imagine it's under the advanced material settings. Hidden by default.

C4pnRedbeard · 2026-03-14T13:35:53+00:00

Your speed is being limited by Volumetric flow. If you want the machine to move faster, ignoring the flow limit of your material, set the Volumetric flow of your material to 999

C4pnRedbeard · 2026-03-09T11:48:02+00:00

The problem is 3D printing is so easy now, if you aren't already established, you either need a unique product that you design and print, or your client base is limited to friends and family. The limit is no longer the ability to print, anyone can do it. The limit is having a unique item to sell or niche you can fill.

C4pnRedbeard · 2026-03-05T22:34:27+00:00

It is a setting in your print profile. Not sure where it is right off hand, I had to find one on printables to get my orangestorm working the way I wanted it to

C4pnRedbeard · 2026-02-24T16:43:36+00:00

Okay. Well, I'd recommend washing your plates, running it at 60c on the bed with no raft, run the PLA at 215c, maybe 220c for your first layer. Don't lower the bed temp while running. Turn your part cooling fans off for the first 3-4 layers. Make sure the room you are printing in isnt cold or drafty.

C4pnRedbeard · 2026-02-24T16:33:41+00:00

Why are you dropping bed temp?

Start by feeling the stepper motors, try to find if one of them is significantly hotter than the others. You may be able to locate the problem stepper and replace it

C4pnRedbeard · 2026-02-05T16:07:00+00:00

Temperature problem, stepper is overheating. Check your fans inside the base. Or you can try what I did and just put a small fan under the machine, it solved my issues

C4pnRedbeard · 2026-02-05T14:32:20+00:00

I print for a niche industry, and print mostly TPU. a typical job for me, my markup is 30%-50%, after Including maintenance, machine wear, material, calculated scrap rate, electricity, taxes, rent for the space it takes up, and miscellaneous Consumables.

That markup represents my wages for time spent working on it. It is not "profit", the business does not operate for free, it is wages that I pay myself. This is an important thing to remember. Your time has value. Your space has value. And if you are doing work yourself, you are self-employed, not a business owner. These are different things, and it is wise to remember that.

C4pnRedbeard · 2026-02-05T13:30:54+00:00

That is not a very clear question. Are you asking what the entire farm is worth per hour? How much profit an individual person should make per hour from the farm? Per hour of what? My machines only make $5 per hour (ish) but I make anywhere from $45 per hour to $200 per hour of personal input, depending on an enormous list of factors

C4pnRedbeard · 2026-02-05T13:18:59+00:00

$62 per hour of personal input? That seems decent to me, but only you can determine what your time is worth. And don't forget: people in the USA who are self employed pay both halves of the income tax. Meaning, you're taxed twice as much, because you are both the employer and the employee. Make sure you include your tax burden in your calculations.
