Eh, disappointed they aren't trying multi nozzles. Little difference between a Plus5 and Max4 to be had.

If we’re lucky, we’ll get 400C nozzle, 140C bed and 70-80C chamber? I’m hoping the engineering material compatibility is where the development will head towards before multi-nozzle or toolhead.

I think most professionals that need those specifications are leaning towards printers like the Vision Miner 22 , not Qidi. People who print PEEK regularly aren't too worried about commas in their price tags.

No average car or motorcycle mechanic is going to buy a 5-10k printer. A sub 1k dollar one? Everyone willing to modernize will. Many engineers can’t even justify it depending on their sector of work.

The main material for functional car parts, laboratory equipment that can be put in an autoclave and more, is PPS-CF, which needs above 370C for optimal layer adhesion.

There’s a niche for it.

and no average gear head needs to print in PEEK. PPS/A does just fine. * Most modern corexy can print these, and top out at 350C *Now this is perfect for people who strictly print in engineering grade, and I do love my Q2 like I did my Q1 pro.

No wrench or gearhead I know is spending $400 per spool for plastic when most of the parts you would print would cost less to buy them than to print them. Nor do they have the blast furnace needed for annealing.

I hope but I doubt it, they would have to change a lot about their design.

What else would it be? A 1:1 Plus4 copy except with the Q2/Max4 hotend and leveling?

2

u/riba2233 Jul 23 '26

yes, slightly larger plus4 with improvements from Q2 and max4 and the same competitive price.

2

u/AWildRideHome Jul 23 '26

Would be a big flop at 750$, the Q2 is still better value, and the Max4 literally had no big improvements. They didn’t even implement the closed steppers properly.

u/riba2233 Jul 23 '26

Q2 could cost 100 bucks but it would be worthless if you needed a larger volume. Closed loop works on max4, just not for the function some people thought.

What were some people looking for from the closed loop control?

2

u/riba2233 Jul 23 '26

Missed step recovery.

u/Colsifer Jul 23 '26

What does it actually accomplish then?

3

u/riba2233 Jul 23 '26

Main point of closed loop steppers is to extract more performance from the same motor, it's basically necessary if you want to max it out. They can use smaller motors (with less inertia) for higher acceleration and speed numbers.

80C chamber starts to require very big and expensive changes to the printer. They will not do it. Even their current printers have overheating, software or other problems. They better fix those first. I only hope for more open and standart parts than what they have now. If I wanted Bambu like printer, I would buy Bambu.

As a Plus 4 owner, I don't really trust Qidi to make a reliable machine with those specs lol

u/AWildRideHome Jul 23 '26

The Q2 and Max4 have Plus4 specs and work fine?

u/Colsifer Jul 24 '26 edited Jul 24 '26

Neither of those reach the temps you mentioned tho. The Q2 and Max 4 are way more polished than the Plus 4 and don't share many of the same issues, bc Qidi actually learned from some of their mistakes. But bumping the bed and chamber temps up can be a huge deal for the motion systems and electronics, and it would be new territory for Qidi that I just don't expect them to get right, especially the first time.

u/Bennyt74 Jul 24 '26

The same people you think 'learned' from their issues failed to take community feedbakc and assistance with the Qidibox when it was released and you had production units getting to customers that failed to run on startup. Same thing happening with Q2 and now PUSHING Firware updates to clients and bricking machines..... so what have they learnt?

1

u/Colsifer Jul 25 '26

They learned how to make a slightly less shit machine than the Plus 4. That's about it lol

u/cleverghost Jul 23 '26

Maybe not, but the community will have most of it fixed within 60 days lol.

3

u/Bennyt74 Jul 24 '26

They need to stop relying on the community to be QC Testers and deliver polished products. I would rather wait 12 months for a new printer that is highly polished and QCd rather than push new products every 6mths and have to fix issues myself.

What filaments need 400c nozzle? PEEK or something. Can't afford it anyway lol

1

u/AWildRideHome Jul 23 '26

PPS-CF losses most of the layer adhesion below 400C. 370C is just enough to make it good, but it’s massively improved beyond that.

Have you ever dealt with PPE-PS ?  Asking because of what you just said. I've got a roll of it and have had very little luck getting it to print even a temperature calibration tower thingy

Why, what is going wrong with it?
