Artillery Sidewinder X1
Looks an interesting piece of kit. Does the hood/cover come with or is that an option?
As far as I'm aware, no official cover is available. Be aware, being a bed slinger type, and cover has to by significantly deeper than the depth of the machine, to accommodate the bed moving.
X1 is, AFAIK, no longer available, replaced with the X2 2 or 3 years back. X2 runs a (locked) later version of Marlin, and has a BL touch type bed levelling (but you still need to level the bed - people think bed auto bed levelling means they dont have to do the bed levelling manually).
Downside of the Sidewinders (and smaller Genius) is the tubing in the hot end means reliability issues when printing hot filaments like PETG and ABS (not that I'd recommend ABS to anyone until they known what they are doing), as the PTFE tubing starts to degrade at around 240C, and my profile for PETG on the Artillery does the first layer at 235C, so little margin there. I did always keep a spare complete extruder here every time I screwed one up. I used to pick up spare complete extruder assemblies for around £25 when they were on offer.
Banggood is probably the best place to by Artillery, should be able to get a Sidewinder X2 for under £200. Sidewinder does need a lot of space, so if you just want to dick around, a smaller printer might be a better option initially.
Just be wary of the limitations of bed slingers, but also note that consumer CoreXY type are still relatively immature. All 3D printers will involve some level of faffage, they are getting better, but not quite mainstream fire and forget yet.
