Hello, I am new to this forum and I was looking for information of "pinion & rack & gear reduction with spring tension" -packs - similar to cncrouterparts version of
PRO Rack and Pinion Drive, NEMA 34.
Reasons why I decided to use rack & pinion were exactly those that JF mentioned above (+ the option to make extensions later). So if anyone can help me where can I get as ready sollution as possible I am interested to hear. Nema 34 and module probably 1.25 with straight teeth (the rack can be cut with laser).
