GeekDoc 226 Posted February 20, 2013 Share Posted February 20, 2013 Satya: You would probably get much better response by starting your own topic. Just title it with something descriptive; perhaps "Need help with 5 axis stepper controller". More members would see that title (and possibly answer) than will see your single post in this thread. Good luck! Quote Link to post Share on other sites
Dirk 0 Posted April 14, 2013 Share Posted April 14, 2013 Are ther new PCB-Layouts? Eagle or Target 3001? Thx Dirk Quote Link to post Share on other sites
roadrunner84 466 Posted April 15, 2013 Share Posted April 15, 2013 It looks like you have two components on the back side of the board, moving those to the top would greaylu improve producability (single batch paste, placement and reflow without using adhesive) Just out of curiosity; you use arched tracks while most people stick with the 45 degrees angles design, why? The tracks leaving from the stepper drivers are very wide, wider than the pads of the driver. while this may add to the ability to conduct high currents, you decrese the spacing between the tracks, which restricts higher voltages. As a rule of thumb, keep 1 mm clearance per 100 volts. I think you can best keep the tracks no wider than the pads to solder the feet of the drivers to. Quote Link to post Share on other sites
