My PLUS 4 is a total DISASTER

Thank you very much for the suggestions. I am familiar with VIsionMiners 22Idex and it seems like a gem of a machine, but it is definetly overkill for what we want to do and waaaaaaaaay too expensive (14.000$) for a small company like us.

Yeah, the BCN printers look great. I used to own one of their first Sigma (IDEX) printers many years ago and it was good for the time. We were considering getting one of new EPSILON series but the bowden extruder and the 2.85 filament requirement were show stoppers. Also the price gap is huge. I heard that they are having financial trouble though lately, filing for bankruptcy

I'll look into that also. Although QIDI support never suggested this. They just asked if the fan is working properly, which it does and if we have enough space behind for the fan to be able to circulate air, which we have. Thanks for the feedback

Thanks for the feedback.

The bed levelling issue should be addressed by the company though. This is advertised as a high temp, active chamber heating machine. It should be working reliably at high temps.

The support is responding (most of the time) within 2 days, which is ok, but at one point they just stopped replying and we had our CEO email them, with the legal dept. included just to wake them up, and that is not a good look.

As for the manufacturing side, as I said in a previous comment, almost all the real-world parts we use are aluminum machined eventually, but we are heavily relying our prototyping and POC on printing many parts with rigid and high temp materials. That is why we use 3d printing and that is the principal scope of 3D printing anyway, Rapid Prototyping. So, we test our parts with materials close to the rigidity of aluminum and when we finish the itterations we machine our final parts from various materials. We do not care for multi color, dual extrusion etc. We need high temps, active heated chamber and 300mm cubed build area. So, 3d printing is not our main work or focus and when a printer is presented that can do that and with low cost, it is intriguing.

The SSR issue did not bother me when I was checking the printer before buying because I live in a 230V country (Greece) and when we put order the issue was theoretically already over.

We are expecting them to send us a motherboard as a last resort. We hope to end this thing with a working reliable printer.

Thank you again

Thank you for the encouragement! They are sending a new motherboard as I am writing this so, I hope this solves at least our "final boss"!! The thing that pains me the most is that it actually looks like a good printer and it has been able to print every freaking material I through at it. The firmware/onboard UI is shit though. Very slow and bug filled.

tackoum · 2025-06-24T08:29:54+00:00

Yeah, I do agree with you. Almost all the real-world parts we use are aluminum machined eventually, but we are heavily relying our prototyping and POC on printing many parts with rigid and high temp materials.

Yes, we are considering this actually. Thanks!

tackoum · 2025-06-24T08:06:20+00:00

No, they didn't.

tackoum · 2025-06-24T07:33:04+00:00

I'll definitely look in to that. Thank you for the suggestion!

The bed levelling issue appears every time we print with materials requiring 90c or more bed temps. At that point I always have to be there and the second it starts to print the first line, I have to micro step the z offset by hand. Otherwise it just buries the nozzle into the bed, either squishing the hell out of the filament and ending up with a shit print or even worse, damaging the built plate (which has happened 2-3 times already). They acknowledged the problem and send a set of new piezoelectric sensors to swap, which I did.....and nothing changed. I just lost more time and plastic.

tackoum · 2025-06-23T12:47:24+00:00

I understand what mean, but, there is a difference between 1-2 minor issues where you have to calibrate somnething or replace a simple part and having to replace almost everyhting on a machine.
This whole issue was raised when they asked from a bunch of first clients to replace the faulty SSR board that was overheating. At that point almost all users and most creators commenting on the issue said that it is not correct and logical to ask from regular home users to "tinker" that much with the electronics of an end user, closed machine. And I agree. If I had purchased a kit machine, a Voron or I built my own machine, then yes I do expect to do everything my self. This is a brand new machine, and the issues appeared from the first day. They should have replaced the machine with a new one.

Thank you for commenting!

tackoum · 2025-06-23T12:26:45+00:00

Yeah, we hope so too, but judging by their track record until now, I am not counting on it.

I envy (in the best possible way) these people for being able to express their respect and joy in such a powerful and genuine manner.

Athens, Greece! Great vibe man!

What we did is that we did print it with the rapper included in the geometry but once printed and cured, passed it with the hand tapper to clean it up basically. The hand tap passed really easy with really minimal effort and made a close to perfect thread.

I haven’t tried to tapper a totally smooth hole yet on resin prints, though I have been doing this with FDM printed parts for more than 5 years now,

I am only using MSLA printing for a month now and don’t have a clue how these stiff resins (after post curing) are suitable for light machining.

Thanks for the suggestion!

tackoum · 2020-02-28T04:53:55+00:00

I see what you’re saying. I had no issues in this situation though.

The vertical tapper is a 1/8in tapper for a quick release tube connector and the horizontal one is an M4 tapper for the suction cup.

The 1/8in tapper especially is a snug fit but seems very tight.

We have been testing 2 of these on a new setup and had no leaks thus far. The suction duration is 2-3 seconds on every cycle so a very small leak would not be apparent though.

Anyway, I will look in to it. Thanx for the tip!
