What printer around 600€

[curious aardvark]

make sure it's the same delta !
None of the kits I saw on amazon were as good or gave as large a build volume and they were all more expensive. Get it direct from www.reprapmall.com
plus even with import tax I only paid £193 - so about 220 euros.
The he3d k200 is definietly the best value and quality delta kit around. Even with the few niggles.

As a first printer - I'd still go wth the qidi.
My flashforge creator was £530 about 3-4 years ago. got about 1200 hours on it - never had a single issue that couldn't be traced back to user error :-).
The qidi is the next model up plus fully enclosed.
It's worth the money.

Plus a delta kit will need parts printed before it's 100% - so better as a cheap second printer.
I'd have been completely stuffed as far as getting the delta to work goes, without already having a 3d printer and extra bits for 3d printers in my workshop.
