How do you support the motor other than the screws?

Oh and to continue to question.... spherical bearings? Why?

Pod - two screws at the back for adjusting float, the front screws aren't used because there's a centre pivot overhanging the front of the pod preventing it lifting but not affecting it's ability to roll
Spherical bearings - because they're the smallest bearings available in what's a restricted space

Kevan, you have answered the sperical bearings question, thank you.....but the way your post described how the motor position/height could be changed(raised or lowered) because the fixing screws and the motor bearing had a slot to move in, in the end of the pod....am I correct in that understanding? and if so ....I asked what else supports the motor? just the screws?

I think Kevans motor pods are similar to mine,
maybe this photo makes it clear

The motor is fixed height ,the axle can move up or down,the bushings beibg driven by 2 screws .

RE: 3DP Pods - Kevan - 28th-Jun-23

The motor is held in with two M2 screws as per normal, the adjustable height is the axle.

It was your idea I liked enough to steal Thumbup

RE: 3DP Pods - munter - 28th-Jun-23

Kevan, in post #5 you talk about motor height being adjustable... this is what I am referring to

RE: 3DP Pods - Kevan - 28th-Jun-23

Yeah I did have vertically elongated motor screw holes but never used that idea and ditched the idea in the end.

...easy enough to do with any pod though with a round needle file and is something I have done in the past. Also elongating the screw holes sideways on a SW pod to adjust the gearmesh when I needed to fit a larger pinion (I've done this often actually).

Good thinking

RE: 3DP Pods - chappyman66 - 30th-Jun-23

As Kevan points out, it's easy enough to design an oval hole for the shaft bearing and screw holes to allow gear mesh adjustment.
I still run glue to hold everything in place.... it's the equivalent of soldering the motor in place on a brass/wire car.

RE: 3DP Pods - chappyman66 - 30th-Jun-23

And I suppose I should clarify....I run Inland white PLA+ nearly exclusively so once the printer is dialed in its mostly push-to-print until the Bowden or nozzle needs to be replaced.
