<h3>Extender for Stepperonline 17HSxx-xxxxS-PG27&nbsp;</h3><p>It was hard for me to get the steppers from the BOM of the Keen-One EQ mount, I also had two 27:1 geared steppers from another project (Stepperonline <strong>17HS13-0404S-PG27</strong> 0.4A/28.5mH) and I have them want to install it.<br>However, the gearbox of this stepper is a bit longer and so I had to design an extender. In the On-Step Calculator, after entering the data, the <strong>27:1</strong> was also more suitable than a <strong>5:1</strong>.</p><p><br>But… With this stepper i have, there is a problem with higher speeds. More than 0.9°/s in the GoTo is not possible, unfortunately the 0.4A motor cannot keep up. I ordered new motors that can rotate faster:</p><p>Stepperonline <strong>17HS15-1684S-PG27</strong> 1.68A/3.2mH</p><p>This is the same gearbox but with a different stepper motor, so the extender fits this one too.<br>With this stepper I have now reached a Goto speed of <strong>2.5°/s</strong>, now i am happy with that :)</p><p>&nbsp;</p><p>Happy printing!</p>
