Still in progress !!
Works with a few tweaks.
Conversion from the factory rail with rollers to a 300mm KGN15 rail with MGN15H carriage.
V3:
Same issues as V2.
Added spacer for printhead (Druk X 5) Best to print in TPU.
Small tweaks to all parts.
There is no need to cut out some fragments on left belt guide and endstop adapter.
V2:
Known issues:
Y axis is ~15mm of.
X axis is ~5mm of.
The purge line can be off the bed depending on start gcode.
Tinkering with limit switch will probably help.
Printing without supports.
I used transparent PET-G with 100% infill, trying to get the glass look but it didn't work.
Only the carriage must be durable/stiff with higher thermal resistance.
Necessary things:
-T-Slot profile 20x20x360mm (the original from Elegoo N4Pro is incompatible)
-2x Roller with bearings GT2 20T 5mm
-MGN15H carriage
-300mm Rail KGN15
-1000mm Belt 6mm
-Invert X axis Stepper Motor Direction.
The simplest way is in printer.cfg change [stepper_x] from dir_pin:PC13 to dir_pin:!PC13
Also change the position of the limit switch
