Glad to see you are making progress Doug. What are the dimensions?

Im building a similar size now, have you thought about cross bracing?

Build has progressed a little now Duet is mounted in a box under the bottom plate New legs fitted to lift the whole thing to allow this (May need to increase them a bit more tho so PSU will also fit under there.

400mm build plate fitted (Still waiting for the heater mind)

PanelDue also in its box still need to decide how to fit to the frame.

Make sure you can still get at the Erase and Reset buttons so that you can flash new firmware, or else add flying leads to new buttons. I have suggested to T3P3 that on the next iteration of the Duet, they use horizontal mounting push buttons on the same edge of the board as the connectors.
Fair point will have to think about that wonder if I could maybe arrange something like Bowden tube with filament thru it as remote push buttons? is there breakouts for the buttons on the expansion header by any Chance will have to have a look at the diagrams I think?

With such a large build plate, I guess you will be using a mains powered heater and zero crossing SSR?
Yes 220v AC 300mm diameter, under the mirror is a 5mm thick aluminium blank at 400mm dia

For my Mini Kossel I drilled two 3mm holes in the bottom edge of the enclosure and screwed it on top of the front top extrusion. As your printer is larger, I guess you could also fit it underneath the top extrusion.
I have drawn up a bracket that mounts to the extrusions and then the Panel will sit on that unfortunately my I3 thru a wobbly yesterday and looks like my PSU has either blown a fuse or has died (Not had chance to check it out yet)!
Dave I do have a question though my build height (Bed to Nozzle) when homed is approx. 515 mm what would you suggest as the homed height setting in the Config.g file does it need to be more than this say 530?

Initially, set the homed height slightly higher than the vertical range at the centre so that you are sure of being able to reach the bed. Once you have a working Z probe, you can use G32 to set the homed height along with the endstop corrections and delta radius.
You will also need to edit homedelta.g to increase the amount of movement allowed when homing.

You should have said you wanted a right angle connector on the sensor board, I could have fitted one for you instead of the usual straight one!
Do the ball ends sit directly in the printed parts, or is there some sort of spherical socket embedded in them?

Think I will have to move the whole hotend to below the effector to be able to fit the board underneath Shouldn't be hard to modify it.

Didnt know I would need a right angle connector at the time no worries Maybe you could pop a spare in with the mini board once they are ready.

i have a similar issue on my 3dr which uses the same spring joints as the cherry pi. I measured the rods and made them accurate to within 0.02 mm but still the carriage tilts in the yz plane by about 0.5mm .. i made the carriages twice ,, the rods 2 times... changed springs from softer to harder ones. lubricated joints .. but nothing works... the printer can print out good parts anyways ... so i gave up on solving it.. when i get time i will rip the printer apart and rebuid it using tarrax joints..

I am kind of lost on what is you think is wrong. So you think the distance between the rods and carriage varies between each carriage due to the carriages print layer heights not being even?
Just wondering so I don't make the same mistake.
