T0 not connecting

I need help with extruder. I'm using the 3dChameleon in direct drive mode and my T0 is not properly extruding when I have it selected.

I have tuned the other extruders with the replacedment spacers and they work great. But the T0 is not engaging properly.

When I open the 3DC and have T2 selected, the part with the bearings is stuck and pinching against the bearing real tight which is great.

But when I select T0 i can lift the part off very easily and the bearing is not even touched by the extruder.

I can not use a different tensioner as the bearing is pressed into the black extruder part.

I feel like the camshaft is not working properly on the T0 and T2. Is there something I ccan do about this?

Can you send me an email... I think you might have some parts that are out of spec... I'll get you the correct ones.

Hi Bill, I already have mailed you while my post was stuck for approval and you send me the new parts which work a bit better. Thanks!

I replied to you with some videos and pictures about my extruder as I feel the camshaft is off. I'm close to having this solved and I'm sure it will be file after some tinkering and modifying but that's the hobby :)

Ok, cool! For anyone else, here are the new A+ parts which are slightly longer... they move the motor closer to the outter two extruders to give them a little more pressure. You might need to readjust your tension tuning sliders to accomodate the shift... my suggestion is to go back to the "default/default" configuration in our Tension Tuning Sliders model. https://www.printables.com/model/516300-3dchameleon-replacement-a-parts Bill
