I am looking to buy a 3D printer for my son (and for myself too). We want to print, not tinker, so it should be something that gives great results right from the start.
Can you guide me to a sensible choice?
My first choice would have to be the Prusa MK3S Plus but it is outside the price range I am shopping for, except if I buy used – would that be bad to do?
Realistic choices:
- €380 used Prusa MK3S+, with 10 days printing time
- €400 new Prusa Mini+
- €250 new Ender 3 V2 Neo
Criteria:
- High quality, no hassle. I want to print, not tinker.
- Preferably (semi)assembled.
- Auto bed leveling.
- Auto error detection (filament, power, etc.?).
- Budget up to 600 EUR/USD including extras, excluding filament.
- Speed is not important.
- Size is not important.
- Must not be cloud-based.
Questions:
- Surface?! Smooth, os satin, or textured? (Why) Should I have more than one kind?
- (Why) Do I need an enclosure?
The problem with dual Z is when you turn off the printer, motors lose power and can missalign. You can connect motors with belts or just print some brake-like part that makes enough friction to stop motors from moving under weight of printer itself. Idealy you will have 1 motor per axis
I had a dual Z printer before (Tronxy X8), so I know the issue.
I already mentioned tying the motors together with belts.
But if you want to not do any modifications, you can also move the print head off the bed, disable software endstops and move the Z axis down until both motors start to skip. That sounds bad but doesn’t hurt the mechanics or engines at all, they are built with skips in mind.
That also aligns both Z axies.
