Hello- I use an elegoo Neptune 3 Pro connected to my pc via USB cable as the microSD slot doesn’t seem to work, even with a compatible SD card. My issue is when I run the Elegoo Slicer software, it will not recognize my USB printer, and I do not know the settings for adding one manually. Assistance is appreciated. Also, if there is an alternative slicer software that I could use that would be a delight. As always - Keep your filament dry and your nozzles warm! ---

Are we working on the assumption that there is a profile for your printer in the slicer software. ---

Accidentally deleted my post! Here’s a recap: ~~That is correct. ELEGOO SLICER version 1.5.0.7~~ ( ~~based on ORCA Slicer~~ ) ~~shows no profiles, and only attempts to search for network printers. When I attempt to add a printer, it searches for a network printer automatically. Adding a printer manually requests network information such as hostname, connection method, access code, etc. There appears to be no option to search for USB001 ports where the printer actually is connected.~~ Addendum: When I load a new .3mf file, I am able to change the printer in the settings to the Elegoo model it has. However, I can only export the file as a .stl file to use with Elegoo Cura. I cannot print directly from Elegoo slicer to the printer. ---

I worked out a resolution for thisw issue - dump ELEGOO Slicer in favor of ORCA SLICER plus OCTOPRINT. Now I am working smoothly and can manage the print better on the fly if necessary. Another option, that i didn’t continue with, is using Repetier for printer hosting. Hope this helps someone with USB printing, especially with legacy printers.
