I think I'm going to head to Lowe's later this week and pick up some longer rods.
Should they be made out of a certain type of metal?

I just yesterday took delivery of some parts from McMaster-Carr for this purpose. I'm upgrading my z-axis threaded rod to M8 and going over to a dual-nut with compression spring set up. When ordering I decided I high as well try to add a few inches to the z-axis.
I bought the following:
1 90024A080 Metric 18-8 Stainless Steel Threaded Rod, M8 Size, 1-Meter Length, 1.25 mm Pitch
2 90690A055 Metric Brass Hex Nut, M8 Size, 1.25 mm Pitch, 13 mm Width, 6.5 mm Height, packs of 25
3 94125K839 Metric Compression Spring, Music Wire, 39MM Overall, 11.0MM OD, 1.00MM Wire, packs of 5
4 6112K15 Hardened Precision Metric Steel Shaft, 8 mm Diameter, 800 mm Length
I intend to cut the rods and install them this weekend.
(I also bought a 6" x 6" borosilicate (Pyrex) glass plate for my heated bed, but that's a different subject.)

- but I think you should be able to reach 200mm without modifying your firmware.

DJNOS1978 wrote:So it is very possible, although more difficult, to extend the x and y axis also? Is the firmware the limit to how big a printrbot can be?
DJNOS1978 wrote:I will go read some more. But from what you are saying....Any modification will need new firmware. How would I know which firmware to get? If I wanted to go for the super z axis what firmware is suggested? Is it in the package?
