I'm pretty new to 3d printing and only built and used delta's as some of you know and, I'm very happy with what I have but maybe thinking of dipping my toes into the world of corexy, what are the benefits of this type of printer,
are there some designs that can be followed or is it make your own design only  :shrug:
Just looking for a bit of an insight into it before I spend any cash pics and vids may also be helpful as I'm not a fan of burning my eyes out reading long pages of text  :rofl:

I'm building around this design, in the downloads he has created an calculator, so you put in you desired build volume and bed size and it give you all the sizes required for extrusion and rods

Gaz, the recent printer Trebor has been building is a essentially a CoreXY (Its a TronXY X5s iirc), theres plenty of over the counter XY style machines available nowadays, aswell as a large resource pool online for diy'ing it.

until recent years youd only really find XY setup used in the more expensive brand named printers like Makerbot replicators etc but much like everything in the 3d printing world.... once you have a working printer..... you can just print another ::)

generally when setup right (which is a little more involved than a prusa style but a little less than a Delta) they offer a higher degree of precision over their older prusa kin as their machining tolerances are generally more tighter which cuts out some of the slop prusa's can often suffer with, as a result there also often capable of higher print speeds, also due to the lack of need for the bed to traverse in anything but small increments on the Z-axis (namely just up and down) as appose to large scale movements back and forwards of a Prusa bed it also means that the whole printer can either be more compact and still match a much chunkier prusa for build volume OR the same size as the chunkier Prusa and have a radically larger build volume (the lack of large bed movement also cuts down in loss of build quality)

basically If you wanted to place them in a category they'd fall smack bang in the middle of Prusa style machine and Delta Style in term of performance

Thanks for the reply shawdreamer I would deff want to build my own rather than buy an off the peg version, I bought an off the peg delta and while it was excellent for the money and printed very well, every thing needed upgrading so set about building a new one and used parts that shouldnt need upgrading for some time,
I then built a second one and love the actual build as much as using them, I can feel my bank balance shrinking again already  ::)
The corexy does sound like the next logical step for me a different type of printer rather than another delta and a whole lot of new stuff to learn  ~~

tbf to you Gaz you pretty much jumped in at the deep end anyway (credit were credits due, you managed not to sink like a brick) when you took on a Delta for your first build and then stook with it when taking on a second.

Itll stand you good stead when approaching a XY build as though the XY shouldn't have a steep a learning curve as a Delta build does it is however a great deal more complex If you approached it from the other end of the scale (eg Prusa end) Even though on first glance the XY does appear to have more in common with a Prusa design wise a great deal of its operation principals are closer to how a Delta operates.

their actually alot more simple than they first appear once you get past the "wait..... that belt goes there............. then it loops around there.........then.....no wait..... first it needs to cross over itself then go........ no wait......." part :laugh:
