That's another compromise for ease of maintenance.

Entire extruder (inc endstop hidden behind) can be removed with 4 screws (plus PWR and CANBUS wire).

Belt can be removed by 1 screws.

L-extruder has +/- 0.5mm Z travel range for Z-height sync with R-extruder (which has BLTouch)

Dragchain and X-carrier will be printed as single unit later to reduce parts count. I've them as separate pieces to tryout different design instead of reprint entire thing)

Extruder -to- X-carrier alignment block need to be redo later as single longer block at middle.

I'd tried X rail on top design. It work well with Bondtech LGX + Slice Engineering Mosquito combo, basically sandwich the X-carrier between them. But with E3D Hermera there is not much option to move rail to the top, since the mounting hole is on the side.

@infiniteloop I got it works as you described. Thank you!!!

Some detail for future reference.

No strange behavior during power on nor power lost. Everything looks good.

Note: the board next to relay is isolated PWN to 0-10V converter, in case someone wondering.

@mrehorstdmd The SLA printer seems pickup a bit in modeling community. But FDM is really going no where. I've no clue why since I just move here 2yrs ago.

I'm doing PETG all around right now to during prototyping stage, and then going over to PC print. 2nd attempt has more 2D-only design which should ease the machining if needed.

2nd attempt here:

@titusou Thanks for pointing that out. I still think that this is not an acceptable solution. Why would I need to rewire my heaters just to get things right on the panel? Wiring is complex anyway, so I tried to simplify it by using Duex5 for all my heaters (except bed of course). So, still, I think PanelDue is an inferior solution to any wifi enabled touch screen device out there. And I cannot recommend to buy it - except for simple default setups, which is not what Duet boards are made for, right?

I won't keep banging my head on the same spot regarding this issue, but still hope that this will be fixed soon. Or then I just toss it and replace it with wifi touch.
