No cable tension meaning no cable attached, will check cassette ibut pretty certain it’s correct

Have you got a chain fitted? Some frame designs will foul on some mechs, if the chain isn't in place to pull the lower cage away from the various bits of dropout.

Some frames foul on some mechs even with a chain fitted. Often the only way to create clearance in this instance is to add b-tension. This is to be avoided where possible though, as it will reduce the accuracy of your shifting.

First thing to work out is what is coming into contact with what, that is stopping the mech from being able to move as far outboard as it needs to. A photo of which parts are touching may be useful.

With a chain on or without. The mech itself stops moving to the right before it’s far enough to the right, the h screw is above the stop and not doing anything.

Can you see whats stopping it moving any further outboard? Something must be hitting something. It could even be an internal part of the mech hitting another internal part of the mech (ie, its not fouling on the frame) but something is stopping it moving. First thing to do is work out what that something is, then work out how to rectify it.

Don’t they all stop moving mechanically in both directions by design? Looks to be functioning normally and not binding or hitting anything.

No, you can't adjust the new SRAM derailleur clutches it appears (I thought you couldn't adjust any of them, but it appears gen 1/2 were adjustable, but gen 3 isn't). It seems like someone encountered a similar issue part way down this thread (for a different derailleur, but same problem).

As for the other derailleur problem in this thread... Maybe a photo or two would help?

Yes, thats what I meant by an internal part of the mech hitting another internal part of the mech. Something has to contact something to stop the mech moving any further. The first step to solving your issue, is to get eyes on what is limiting the movement of the mech. Step two is working out what to do about it. But first off we need to know whats hitting what.

Have a brand new Devinci Troy frame.
New gx eagle 10-52

With no cable tension and the h screw no longer making contact I still can’t get the jockey wheel to align underneath my smallest cog. What am I missing? should have more than enough adjustment to get to an beyond the 10t

My guess is the cassette is not installed all the way. If you think the derailleur and hanger are fine, it must be the cassette's location.

The cassette was not all the way tight, snugged it up and problem solved.

No adjusting on that one.

Once you're getting chain slap you either warranty the derailleur or buy another one.

If you have the bearing exposed you can usually read its code and then just order a bearing with that exact same code. Baring that, bust out your calipers and measure ID OD and width and order the bearings that match those dimensions.

or you just accept that some chain slap is normal and ride the damn bike.

Haha no. I prefer the bike quiet. Axs mtb derailleur clutches are not up to the task and it's known.

Wait for next gen tho its supposed to be actually serviceable!

I mean like I guess you could cut the chain a link short maybe, but it would probably affect shifting especiallly with how finicky sram eagle is. If you really want it quiet get one of those STFU chain slap things. Supposed to really help.
