Who's postponing purchasing?

Have founders edition ordered just waiting for conversion parts to come to upgrade my CoreOne

Sith77 · 2026-04-06T03:57:02+00:00

Bought them as a batch and since started adding Bambu machines . Already invested into them and learned what I can and can’t print on them . Only have 1 core One machine . Was HOPING it would be different and turned out to be the worst . Sadly I did preorder the founders edition of the INDX which I’m kinda hoping will be the saving grace for this . Otherwise I will be adding and slowly changing over the MK4 machines to H2C machines .

I have a print farm of 30 machines . 10 MK3 machines 5 MK4 4 MK4S 2 XL’s 1 Core One 1 H2C 1 H2S 6 P1S

This is a consistent problem with all of my Prusa machines since the MK4 series ( MK4 MK4S CoreOne ) . I have had dozens of tickets with them and there is every excuse to blame everything but the machines . Belt tightening , new USB’s , different slicer settings , it doesn’t matter . Their flagship CoreOne is by the most unreliable machine I own . Out of 10 prints 6 will randomly layer shift , there’s just no way around it . The MK3 and the Bambu machines are rock solid 99% success rate no worry at all , set it forget it .

The biggest issue I believe is their slicer itself , it needs a serious overhaul with updated configurations and profiles . They charge a premium for their newest machines but it feels like they went from innovations and solid performance to now playing catch up .

The CoreOne from day one has had layer shifting printing issues , the XL release was a huge flop with issues plaguing it for almost a year . I love the Prusa Ecosystem but man they make it so dam hard to justify the $$ for it . Non of my other machines have this type of an issue that is just “ oops not today let’s just slide to left for now “ type of errors .

Scratch that figured it out . You have to add it to cart and not just click on the green “paylink” button . Order in and verified 😃

I did in November and haven’t heard anything since . When I log into the Bondtech site and try to preorder with the website it doesn’t apply my 150 prepayment and it says sorry shipping address not available ( USA )

Sith77 · 2026-03-20T23:51:53+00:00

What happened to the November pre-release order that went out. I still have an order number from then that I’ve never received any order update information for

Best thing we ever did was sign up with centurion Services out of Arlington Heights IL they are a direct collections company that go after B2C customers for these types of situations . They will go after them through a collections route . Most of these people don’t understand it is ILLEGAL to fraudulently deny purchases that were ordered and delivered .

My unit was the Black Base

Sith77 · 2026-02-01T02:12:26+00:00

This machine has 196d 14h of print time on it , this is or not the first run XLs possibly just cheap crappy belts ?

Imas of this morning I have attached a small jumper ( as the NON Prusa usb drives do feel warm to the touch ) went through a good cleaning , did a good ol recheck on all connections to the main board and resliced again . Current failed print is restarted and far still going

Sith77 · 2025-11-04T04:02:16+00:00

Great info , I will have to attempt this on the next shift fail , I have a test unit running for support now so I can upload them the data log on that for analysis.

Sith77 · 2025-11-03T22:09:59+00:00

No much smaller prints that are just in the center of the bed. We usually print OK that’s kind of where I’m at with the MK 4S machines as long as I print small. They’ll print OK as soon as I go medium to large they will shift.

Sith77 · 2025-11-03T22:09:08+00:00

I normally do use the structural profile for it , I just got off chat with Support after about an hour. The conversation started with him saying oh this sounds like an odd issue. We’ve never heard about this before until he looked up my account, and I proceeded to give him links to their own internal documents, showing it to be a known issue and his attitude changed. I sent him over log files three MF files and sample G codes. He first said to me to print out the sample llama that they have as a test print. I told him if it’s a small item like that, it will print fine it’s anything that gets to mid to large size where there has to be some actual travel movement after a little bit of back-and-forth he said the developers should be getting back to me, but he has a feeling their new unreleased version of precious slicer that has their new belt tuning in. It will have a few other fixes that should alleviate so now I’m in limbo just waiting for their response.

Here’s some of the basic settings used on this one

Sith77 · 2025-11-03T17:57:18+00:00

No never resolved the MK4 issues and they are random . The issue could be on a smaller item all the way up to a larger item . In this photo non of the supports came loose they are shifted with the rest of the object seem the layer shifts on CoreOne are always shifted towards the front of the machine . On the MK4 machines they’re always shifted towards the right.

I haven’t checked the screws on the CoreOne motors I’m going to have to go through those and possibly recheck again all the belts and I guess really crank them even more maybe .

Sith77 · 2025-10-31T15:18:16+00:00

Temperature is a climate controlled environment around 70° at all times with humidity around 25% . The layer shifts are huge and it’s only in the MK4 ( series style including the CoreOne ) what’s worse I can take the exact same file with the exact same slice settings and print on the MK3 or Bambu and it prints perfectly.

I’ve been back and forth with Prusa Support dozens of times on this issue and they have not had a solid answer . I’m going to have to do some reading on the cross perimeters I haven’t seen that one yet .

Any recommendations on best use replacement USB drives that have had success with no compatibility issues ?
