Lately, I've been having more and more problems with my MakerBot not printing reliably, and I've worked out that the problem is very likely the power supply giving up. So, I've finally bit the bullet and bought an new power supply!
It's a 500 watt supply with two 12V 18A rails, that way I can have one rail power the steppers, and one rail power the heaters. I think that having a more powerful supply will help quite a lot!
Also, Finally bought the Acme rod upgrade :-) switching to 4 leadscrews should help quite a bit to eliminate the wobble, However, We'll see if it'll still be able to move accurately enough!
I'll post pictures once I get everything working!
