After my son's request, we have build a new 3d printer...
It's a TronXY X5SA PRO, with auto leveling future, and the ability to print flexibles out of the box (titan e3d extruder).
The kit is exactly like his ancestors...
A work in progress with a dissent value for money...
Good motion system but in desperate need of a good firmware...
Be aware of the fact that the manufacturer sends this fire hazard with disabled temperature error detection (M8023 T1 ; Forbidding temperature error detection )
Anyway as far as the assembly difficulty, as a proof of concept, the kit was assembled successfully by my son... (with my help, but nevertheless by a 7 year old boy)
