3D Printer Tips
Which Printer
You needs may not match mine, so your choice of printer may be different. For example, if you want to print miniature models for D&D style games, then a resin printer is probably best. I like functional prints, such as boxes, boor knobs, shelf brackets, and therefore I prefer filament printers.
I recommend Genius or its big brother X1 from Artillery3d. They take very little set up, reasonable quality and speed, and are inexpensive. The textured glass bed is perfect for my needs (but do take care if you use PETG).
Tweaks
I like to print at a push of a button (I don't want to transfer files using an SD card or USB stick). So each of my printers has a Raspberry PI attached to it running OctoPrint.
If you do go down this road, then the run out sensor on the printer is useless IMHO, so remove it completely including the wire to the base. It is very easy to do, and can be reattached if you change your mind.
BTW, if you attach the Raspberry Pi to the printer, then the Pi may be powered via the USB lead, but the printer cannot supply enough current, and the voltage drops (Bad!). I've modded my USB leads, cutting the red power line to prevent this.
The printer come with no lubrication, nor does it suggest you add any. However, surely there should be lube on the Z axis screw threads. It is metal on metal otherwise.
The SD card and USB stick sockets face upwards, which is a dreadful design - dust and debris WILL fall in. I've printed name tags for each of my printers (with magnets) that cover these sockets.
If you choose the X1, then consider changing using a nozzle with a larger diameter (0.4mm is tiny for such a large printer).
Warnings
Do NOT print the cube included on the USB stick; the temperature settings are too high! 80°C for the bed and 230°C for the hot end? Why? Do they think people will use ABS for their first prints? PLA is king, so 210° and 50° are more reasonable.
If you leave the printer in the "Change Filament" menu, it will keep the hot-end heated, which could cause a fire. (The filament will eventually break down, and begin to burn).
Printers take up a LOT of space, especially the "Plate Slinger" types, whose bed moves backwards and forwards.
The printers claim that you can restart a print after a power failure. Not really true. It only works when printing from removable media, not via OctoPrint or directly from your computer via USB. Also, if the bed cools down, the print will release from the bed, and printing cannot be restarted.
