@danal I assumed that was the issue, I'll see if some brackets similar to my effector ones since the issue, otherwise I'll be looking for affordable (read budget) magnet rods

@fcwilt I don't have the tools to make something with sufficient precision unfortunately

@bearer Current bed is 200mm diameter, 6 3mm holes seemingly evenly spaced around it, 7mm inset from edge to center of the hole. Pic is a brief sketch I threw together on F360.

New extrusions can be pretty much whatever length, though I'd probably max out at 300mm to keep the footprint small.

@bearer the current extrusions are 230mm so I can get longer ones relatively easily online (circa £30-40 for the set from oozenest) rewiring to the top would mean making a new loom for a lot of the components which I'd rather avoid (currently don't have most my tools....)

@DIY-O-Sphere I started debating to/on one side, rather than internal. Feet is a good call though, might do that. Thanks

@fcwilt As it's a delta, with the print bed attached to the top of the base extrusions, extending the base extrusions will change the distance between the center of each extrusion where it currently mounts. Picture an equilateral triangle, with a circle touching the middle of each edge. Then make each edge longer, the circle will need to be larger.

Edited from desktop, should have pic visible now

So, whilst upgrading to metal corners I have ended up with the duet not being able to fit between my stepper motors (see pic - edit: Veti, was trying from mobile, pic now attached).

I see my options as:

1. get longer horizontal extrusions, providing more space, but needing a new heated bed/print surface
2. go back to the worn plastic corners and make do
3. be slightly mad and remove motor housing with a file to make this fit...

As you can probably guess, I'd rather do 1 and continue upgrading. However I'm struggling to figure out what size bed (and where I'd get it, I'm uk based) for what size horizontals.

All help appreciated

@bpislife adapter is part of the package. Going to try printing brackets for them to see if it works, otherwise going with https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F132544828361

@barracuda72 basically because I hadn't thought that far all just ebay stuff?

@dc42 is bearing spacing essentially space between the ends of the two rods? So across carriage and across effector? Think the rods move ok, they certainly do effector end.
