Re: First 3D Printer Decision - 8 years ago
QuoteTidsuo Hello all! I am very new to the field of 3D printing and was hoping that I could get some pointers as to what I should look for for my first printer. I originally thought of getting a pre-assembled printer but they seem to be on the expensive side. Then I stumbled upon RepRaps. I have looked at many different types of printers and I think the Prusa I3 type is the best for a beginnerby Mach - Prusa i3 and variants

Do i need to solder in some pins or should I just solder the wire to the pad?

Quotechz420 Im using the Folger Tech Prusa i3 acrylic kit. It uses an arduino mega 2560 and RAMPS 1.4 shield. Ive been going back and forth through email for the past couple weeks (months) with their tech support trying to figure this out. Ive so far received 2 replacement megas, 3 RAMPS, and an additional set of stepper drivers. So in total I have 3 arduinos, 4 RAMPS shields, and 2 sets of stepby Mach - RAMPS Electronics

So I just got done trying out craftware, and....I am disappointed. It is missing so many features that using it right this point would be too inconvenient. One thing that I really was surprised to find is that you cannot even connect to and manually control the printer other than the temperature.

QuoteUltiFix WOW, O MY GOSH I lowered my stepper voltage for my x axis to .217 and it's so much quieter!!! I can't believe how much of a difference that made! And it's sooooooo smooth! I'm not quite sure what range it should be since I adjusted mine by sound, but I think .2 is abit low.
