Wades filament path seems to have changed

[nophead]

The hole for the filament no longer seems to line up with the centre of the idler. I.e. I think it has changed position from the original. This will mean bought in hobbed bolts will not be compatible.

Theres 0.2mm deviation which cant do anything wrong and its probably caused by smaller diameter of filament guide and my crappy measuring in netfabb :-)

The reason I noticed a problem was I tried a hobbed bolt from an original Wade's and it does not match the filament path. It seems to be because the bearings are not in the right place. There is an odd 3.45mm offset in the bearing definition placing the centre bearing at 14.45 instead of 15 to match the filament. An the other two bearings are not flush with the sides. On Wade's the central bearing is aligned with the filament and I think the other two are flush.

I just realised the bearings are only 7mm thick, not 8mm. Things fit a lot better with them set to 7 and the gap set 8 instead of 9.

I got it to line up exactly with Wade's by setting the bearings to 7mm and changing the offset to 3.5mm. I changed the idler slot to 8mm and moved its position to 11.5. It is now central to the filament and the bolts.

oh, thanks!!!
