When you build it for first time or rebuild it. after upgrade to Reprap Air. every thing just get bad!
the Z motor sounds like shit and don't move so i turn down the speed to solve it.
so now i can print again but the z axis wobbling so badly so everything look like crap :P.
so no the last 5 thing i have been printing are to fix the Z axis problem, so it's go better and better.
i have the motors under the axis so i gonna try nut holder for Z-axis, I hope that can fix the wobbling problem even more.
I have print holder for the Slide part, and also axis top stabilizer with bearing.
I hope i can be proud for the printer some day. right now i has take like 3-4 month to with trying to fix manny manny problems.
one interesting problem i have was.. it's working perfect for 2 days and from no ware it scale every thing down to the half and I still don't know way... but it did and after that i get other problems. so at that time I thinking to
give up the reprap project and maybe sell every thing. but after a week i think. NO!
I have working late nights on this Sh*t and can't give up now.
