Vertical Rail Options
There are several options available for the vertical movement carriage of the Kossel Mini. The thing is some options cost a LOT more money. I will show some options along with prices as of 1/1/2014.
1. Use MR12 MGN12C HIWIN rail and truck currently about $140.00 after shipping…
2. Use an additional printed carriage with Dual 623 V rollers currently around $80.00 after shipping…
3. Find some other cheaper rollers. I used some Prime-Line M-6153 rollers from Lowes which ran me under $10.00. They have a little slop in them however the prints are totally acceptable.
