Here is a early design for the Railcore using the LGX extruder with the Mosquito hotend and Euclid probe.
The .step file has been uploaded, so feel free to modify it as needed. My guess is that the euclid probe mount area will need to be strengthened for longevity. Edit: I haven't had any issues yet, but if I do I'll update.
I printed this in PC-CF at 100% infill with 6 walls as well as 6 top and bottom layers.
This model uses the following heatset insert sizes:
M2x2x3.2 - x2 quantity
M2.5x2.5x3.5 - x2 quantity

Here are where the M2.5 heatset inserts go. I used an M2.5x6mm screw to secure the Euclid probe board

Here is where the M2 heatset inserts go for the y-axis endstop
The offsets I used for the euclid prob are: X0 Y30.0 Z2.0
To get started, Duet forum's user “PaulHew” shared an incredibly useful .zip file with examples for your setup. https://forum.duet3d.com/post/267521

Modified to work with the Euclid probe
