I would recommend RAMPS, as it is very compact and gives you plenty of expansion room. However, it can be hard to get a hold of the pololu stepper drivers as they are in short supply. Gen6 would work perfectly fine though.Quote
1.Which electronics would be the best/mostUserFriendly ? Im thinking Gen6 cause i assume i wont have to solder a thing, and its just one board.
Resistor is the easiest by far. Both will give you good results. I personally use a MakerGear hotend, which is very nice and compact, but slightly expensive at $70 or so.Quote
2.Which type or extruder hot end would be the least error prone , and give the best results? nichrome or resistor ?
NEMA 23's won't fit a Mendel, and as jcabrer said, the 17's are plenty powerful enough. Just make sure you get a really strong one for the extruder, something around 3 - 4 kg*cm. The degrees per step isn't a big deal, either 1.8 or 0.9 would work. The micro-stepping of the stepper controllers will give you plenty of accuracy either way.Quote
3.What if any, are the benefits of using nema 23's over 17' , and what degree/step would be best ?
I would recommend printing with PLA from the start, which does not require a heated bed or even printing rafts. That's what I did, and you can always move to ABS as well at a later point if you wish.Quote
4.Should i invest in a heated bed right from the start or is it something easily added? Will the electronics used have to be changed to work with the new bed?
