My new giant printer!
Just finished building this beast. It's a ratrig Vcore 3.1 with a 500x500x500mm build volume and blazing speed.

Wow. I guess you use larger nozzles for something like that? How do you get an extruder to keep up with the flow rate? Also, this is my first post on Lemmy.
On my VC3 500 I use a rapido with a 0.4mm. My default PLA settings are 300mms with 10kmms2 acceleration. I'm not sure about OP but for me the larger build volume lets me kick off a full plate of parts and come back a few hours later. Gets pretty good quality but at that size/weight you do get some ringing on the parts.
Ayy another vc3500 haver. I use a .6mm bondtech CHT volcano, but honestly I've been having trouble getting past 30mm^3 per second, which is unfortunate. My main goal with it is actually giant parts, but the mass production thing is pretty cool too.
North of ~25mm^3 I've found I need to really up the temps to keep up with PLA (mainly using eSun) which then also means a lot more cooling. I managed a pretty decent 14 minute benchy but need to retest as I've upgraded my cooling.
My current setup for extrusion:
- Rapido high flow with CHT
- Orbiter 2 with blowy mod to run at higher current
- CPAP remote cooling with a WS7040 blower
- HUVUD toolboard on printhead
Mine is basically the ratrig recommended defaults except for the CHT, a beacon scanner, and a carbon fiber rail. I got to a 16 minute benchy basically immediately, but anything else I print that fast causes either skipped steps or belt slips and I'm not sure why.
Nice not bad! A pretty easy upgrade for power (if you have a mainboard that supports it) is to go to 48v for the steppers with 5160 step sticks, gobs more power, but you are also now getting to territory where a crash can start really breaking stuff. There is also a group in the discord where they are working on the AWD mod to add 2 more steppers to the XY motion allowing for insane speeds.
Oh so that's what AWD is? Sounds cool. For me though, my issue is probably down to belt tension.
