the artillery is a bowden extruder and central support.

There is absolutely NO reason for making an i3 style printer with a bowden extruder.
It's just adding in complications that are totally unnecessary.

If you don't mind upgrading and twiddling - then start with something that will require the least major changes - at the moment the anet q8 plus is the ONLY budget I3 with all three of main i3 features josef prusa invented.

The socol01 is a good machine, great facebook group and a small company that actually do customer support.
And despire promising me a machine to review - they never sent it - so if anything I ought to be biased against them :-)
But I'm not lol
