I have modified the original NG X carriage to mount the Xol toolhead while not losing any X or Y build volume and be as close as possible to the stock toolhead in terms of reach allowing (hopefully) full compatibility with tools mounted in the back.
Fit and clearances
The positional difference of the nozzle is some 2.5-ish mm further to the front compared to the stock toolhead.
With the 4010 fan version of Xol the fans will touch and deflect the A/B belt a tiny bit at min and max X (see pictures). I haven't tested XolPAP but it seems like that will not be touching.
The Xol body also needs a little bit of filing down near the hotend cable routing channel to prevent a collision with the left Y block (see pictures).
Beacon
I have also included a version with a mount for a beacon probe, it's made with Rev.H in mind but may fit the Rev.D as well as Cartographer and similar that use the same mounting pattern, I have not tested that though.
The beacon's exclusion zone does clip into the lower linear bearing a little (see pictures), but so far I haven't noticed any adverse effects using contact and proximity bed meshing.
With this mounting the beacon will collide with the stock back linear rod mount and potentially damage the probe. The mount needs to be filed down by few mm to prevent collision.
Has built-in supports which need to be removed.
Y offset: 15.4
Measured from the center of the nozzle to the center of the coil according to CAD.
In CAD the nozzle to beacon Z offset is some 1.7-ish mm, with my particular setup I physically measured 3mm, I think my nozzle is slightly longer than in the CAD.
Hopefully this allows enough wiggle room to account for nozzle variance.
Note: The hotend shown in CAD pics is the Trianglelab Rapido Ace UHF with a 3mm spacer which works out to be a about 0.5mm shorter than a normal UHF Rapido.
Hardware and mounting
4-10x E3NG BOM M3 heat inserts (M3x4x4.5)
2x M3x16 SHCS for the top mounting holes as per Xol BOM
2x M3x5 SHCS for the bottom mounting holes
Beacon mounts with the screws included with the probe
