Selecting micro-stepping settings / adjusting voltage

[WillAdams]

Okay, I'm trying to puzzle out the appropriate settings for my Ordbot Quantum connected to an Azteeg X5 mini.

I've got X- and Y-axes moving, but Z- just vibrates. I haven't touched the micro-stepping jumpers, (currently set to the same defaults as an SO2), and am trying to puzzle out what those should be.

I'm using NEMA14 motors: http://www.smartautomation.com.cn/Produ ... icleID=500

SM35HT36-1004A 2.7 1.0 2.7 19 1400 4 14 0.18 36 --- Am I correct in assuming that the "Current/Phase" is the number of amps which which I should set the current to:

Code: Select all

alpha_current                                1.0              # X stepper motor current

So the question is: does the small motor size and holding torque of 19 oz. in. indicate that I should reduce (or eliminate?) micro-stepping. Would starting out at 1/16, then trying to move the machine, then reducing the micro-stepping and adjusting the number of steps until things move be a reasonable strategy? Or would it be better to start at the other end? I did notice that the Prusa configuration page specifically mentions 1/16 micro-stepping for Smoothieboard....

Microstepping should have no adverse effect. Go with it.

Thanks!

1/16 microstepping seems to be fine, except for the matter of one motor not working.

separate post on that.
