E34M1 Cooling Ducts For UHF Hotend With 8mm Probe Mount

A while back, I converted my Creality Ender 5S1 to the Mercury One.1 CoreXY conversion running on Marlin (initially, it ran on Klipper, but I had a problem when my RPI 3b+ failed).  I found that, in trying to dial in the coordinates for bed mesh leveling, my side-mounted inductive kept landing off of the left side of the bed which would not allow it to trigger properly (thus, never completing a mesh).

The original UHF bottom plate/ cooling ducts, when used with the common probe holder on the left side of the tool head, reduce your probe area by up to 50mm on the X-axis when doing any kind of bed mesh leveling.  By extending the bottom plate and mounting my 8mm inductive probe in that area directly behind the nozzle, I can bed mesh the entire bed on the X-axis without losing any bed area on the X-axis.

This makes the bed mesh much more accurate, and allows you to print all the way to about 10mm from the physical edge of the bed.

This was printed on a Mercury One.1 (conversion mod for the Creality Ender 5S1) in Elegoo ABS though a .4mm V6 Volcano hot end, using the following settings in Cura:

• Nozzle Temperature:  255 Initial Layer/ 240 Subsequent Layers

• Bed Temperature: 110 Initial Layer/ 105 Subsequent Layers

• First layer height: 0.25mm

• Layer height: 0.2mm 

• Extrusion width: 0.4mm, forced 

• Infill percentage: 40% 

• Infill type: Adaptive Cubic, grid, gyroid, honeycomb, triangle, or cubic 

• Wall count: 4

• Solid top/bottom layers: 5 

• Seam placement: REAR 

• Supports: NONE

Note: The tool head shown in the photos is my new one that will replace the current one that uses stock UHF horns.
