Mecanum Wheel Rover - Reprint with slight enhancements160779

Reprinting the Mecanum wheels once again for somebody else but chose to increase the look rather. Among the list of commonest queries by new buyers with the Up! 3D Printer is how to take away the raft. The raft is one of the love/hate details from the Up! printer, a number of people desire to do away with it with no recognize the value of it. Some feelings and strategies on this ahead…

The raft is there for many far more causes than simply performing as aid content. Just one of these is always to cater for imperfect calibration of your nozzle vs system top, too as system degree. Could you decide how?

Alternatively than complain about the raft, it's not necessarily too challenging to structure around it. On the list of frustrating items about assembling the initial mecanum wheels was, you guessed it, getting rid of the raft off the rollers.

The raft/support product may be very conveniently taken off off curved surfaces. Substantial flat locations will also be not a challenge, but try to prevent sharp 90 degree capabilities around the bottom of your types. Adding a 0.75mm 45° chamfer was all it took to receive the rollers to snap off the raft easily! The wheel hub also experienced an recessed base (2mm great x ~10mm radius) which at first served to suit the servo horn, even so the raft was painful to get rid of from right here. Resolve? Take out the recess.

Yet another tip is usually to loosen the raft round the edges first, then peel alongside the ‘grain’. Yup, should you glance thoroughly the raft is laid out at diagonal possibly 20 levels to 1 of your print axis. Acquiring a dense (4+) raft and peeling while using the grain offers you finest chance of removing the raft in one piece cleanly.

Probably should really incorporate a video clip demonstrating this but experimenting you simply cannot hurt you. I intentionally additional a photo exactly where I had been half-way taking away the raft/support content around the various items. Oh can any person guess why I'd print that frame inside the orientation I did? Instead than ‘flat’ to the mattress and avoiding all of that guidance materials mecanum wheel?
