background - purchased an Anet A8 from the"factory" - within a week - the SD card slot failed. I had never been able to connect it via USB and Repetier ( using 21inch 2011 Apple iMac running current and updated Sierra 10.12.4) After being refused a free replacement - the attitude changed when I advised a PP case would follow. After another 2 weeks I got it. And I Facebook tip got me a new driver - not apparently available on the Repetier websites downloads.
Meanwhile I had ordered a second A8 ( full spares kit was the thought!) at a reduced intro price offer. A8 - 1, when connected via USB /Repetier… starts too print about 20mm above the bed. Put the same g-Code file on the SD card… prints fine - but I lose the USB - unless somebody knows a cure. A8+1 had problems with the Z drive rods. I think the turning machine broke down and they were finished off by a monkey with an hammer and chisel - two weeks on waiting for BangGood to send out new drive rods and Brass T bearings. IF I try to run teh snagged rods - the left Z motor cannot start up - I am guessing the pits and bumps are stopping smooth motion - even after some patient work with sandpaper ( the fine grain stuff for metal) and a liberal coating of silicone grease.
So with that in mind and the future looking grim if something else fails - I remembered a YT vid of Joe at some faire and showing the - then new kit which allows additional extruders - mutuality colour prints. Delivered to Aussie it about us$1300.
So I was seriously considering getting one on order… then I see on a none specific brand Facebook page a couple of posts where the multi nozzle set up - clogged up and created havoc. So in such a situation - is the guy left to sort it out without advice - or is there a support team?
Is this kit a seriously complicated starter for a newbie?
anybody been in my situation and can offer some advice - which will be appreciated.
