			<description><![CDATA[<p>Well I found my old Sang board. I got the Printrboard because I could never get the firmware to update. So I fiddled around with the firmware&nbsp; again and finally got it to upload without errors. Back to printing for now.</p>]]></description>

			<description><![CDATA[<p>Good to know I just followed Adrian&#039;s advice and explanation.&nbsp; Maybe he doesn&#039;t know everything <img src="https://www.soliforum.com/img/smilies/wink.png" width="15" height="15" alt="wink" /> or at least we might get him to show his face a little more often <img src="https://www.soliforum.com/img/smilies/smile.png" width="15" height="15" alt="smile" /></p>]]></description>

			<description><![CDATA[<div class="quotebox"><cite>wardjr wrote:</cite><blockquote><p>Same board but I went with the 8825 steppers.&nbsp; You can switch them to 1/16th if you need extra torque for say the Y-axis.</p></blockquote></div><p>1/16th drivers and 1/32 drivers will produce the same torque at a given shaft position. Might be good to look into microstepping a bit. <img src="https://www.soliforum.com/img/smilies/smile.png" width="15" height="15" alt="smile" /></p><p>Explained:</p><p>Lets say you have a 1.8deg/step stepper, rated at 100 oz-in of torque.</p><p>at 0 degrees: 100 oz-in torque available<br />at 1.8 degrees: 100 oz-in of torque available</p><p>but if drive it with a 1/2 microstepping driver:</p><p>at 0 degrees: 100 oz-in torque available<br />at 0.9 degrees: 70.7 oz-in of torque available<br />at 1.8 degrees: 100 oz-in of torque available</p><p>So lets say your total load torque is 50 oz-in. Obviously, you&#039;ll always hit the desired position (0, 0.9, or 1.8deg). If your load increases to 80oz-in, then when you command 0.9deg the motor and load won&#039;t move - but they wouldn&#039;t have moved anyway without microstepping!</p><p>tl;dr: microstepping always helps, never hurts. Also tends to make the axis resonate/vibrate a whole lot less. Really no downside, as long as you recognize it isn&#039;t a perfect replacement for a gear ratio. If you need true accuracy at whatever resolution, then you can&#039;t count on microstepping - but if its microstepping or nothing, microstepping is better.</p><p>Actually, a permanent magnet synchronous AC motor is just a stepper motor with infinite micro stepping (1/infinity). Those have plenty of torque, they move trains. <img src="https://www.soliforum.com/img/smilies/smile.png" width="15" height="15" alt="smile" /></p>]]></description>
