Is there any reason I can't make 36 tooth x8mm id pulleys on the

Is there any reason I can’t make 36 tooth x8mm id pulleys on the Z screws? (BOM calls for 30 tooth) I’m going to use 1204 ballscrews instead of leadscrews.

Not at all…the hard part comes when setting the e-steps for that axis. I used something like this: http://littlemachineshop.com/products/product_view.php?ProductID=1593&category=

(There’s some hokey math conversions…you want to end up with e-steps in metric, but the indicator uses inches…unless, you know, you get a metric one to begin with.)

@Mike_Miller yeah, I assume it’s easy to adjust the steps/mm or steps/inch. I did this exercise when I built my mill (Mach3) but ya never know, there could a reason not to do it!
