Z belt rubs back of extruder

As per the topic, I'm getting my Prusa built and changing from V1to V2, I'v just got the new plastic parts to take the bearings and it's all together and square (I hope!), however I still have the original wades extruder.

The problem is that the T2.5 (or any belt) rubs the back of the stepper for the extruder, this gets worse near the motor.

Looks like the stepper needs a few packing washers under the bolts but is that going to fatigue things as it's a heavy item?

My other option is to turn the whole extruder and use the ofset holes, unless I've missed something?

Pretty desperate to crack on with building, but keep hitting these issues

Hmm.... looking at the pics of the TV group Prusa with bearings the extruder is fitted backwards to the visual instructions and probably has more clearance!

All part of catching up I guess, at least I'm not backwards on the carrige or I'd have to strip the whole lot to change the bearings over (whew! )

It just misses on this picture: [www.thereprapkitstore.co.uk]. That is with the V2 X ends and the same extruder you have.

My link goes to the same page as your link.

Yes it looks like it has to be rotated clockwise.

Looks like that's what I'll have to do.

On a happy note, your motor mount was taken into school by my son yesterday took about 2 hours before I got a phone call from the (insert whatever poncey name they have for woodwork/metalwork these days) department, pretty much foaming at the mouth to find out how to buy one. When told they are 'built' I think he thought I was pulling his leg!

Mine or Nopheads?

the whole site is:

www.thereprapkitstore.co.uk

... this were with both links.

But seems to be solved now ... or maybe interesting behaviour with cookies - when I've first clicked on your links, there were every time the 403-error ... but after calling the main page www.thereprapkitstore.co.uk both links show the image
