That's interesting, I thought lead screws were the norm. I didn't start reading through the forum until after built it. Originally I was planning for a CNC then decided to go with a 3d printer. I also didnt want to deal with the hassle of slipping and stretching belts. I'm sure with some quality belts that would not be much of an issue but that was my line of thinking at the time. I wanted a solid machine. Like I mentioned my build is 80% DIY, I only use purpose built parts where I had to. This was because of budget constraints and also just for enjoyment TBH. It is not perfect and I am sure it is not up to the standard of some of the more experienced, but I am quite proud of it, and I don't think it's too bad for someone who up until recently has 0 experience in 3D printing. I have been upgrading it non stop since I got it up and running. Yesterday I strengthened the motor mounts, leveled the x axis, and upgraded one motor. Ever since I upgraded a motor I have noticed a little slip at higher speed. I wasn't sure if it was my coupler or if I need to turn the current up on my driver. I keep the drivers set at about .750v for X and Y but I since turned up the larger stepper (84 oz/in Nema 17) to 1.0. It seems to have helped, but I also marked the positioned of the coupler and motor shaft to check if another slip happens. Right now I working on upgrading my coupler's because the nylon one I am using flex when tighten the set screw causing an imbalance and slight wobble. Suprisingly it hasn't hurt print quality too bad. But, I am not happy with it. I am using cheap hardware store lead screws and I felt like they were better because they gave me a higher resolution but after some thinking yesterday I will probably switch to some with a lower pitch so my motors can spin slower and I will be able to print at higher speeds. I am about to take some pictures and maybe a short video of it running so I can get some specific advice. Like I said I'm new so don't trash my baby too hard.:D
