			<content type="html"><![CDATA[<p>I just installed a BL Touch auto bed level on my CR-10S using this, <a href="https://m.youtube.com/watch?v=U98V1nMwLKk,">https://m.youtube.com/watch?v=U98V1nMwLKk,</a> YouTube video for the firmware upgrade and this, <a href="https://m.youtube.com/watch?v=y_1Kg45APko,">https://m.youtube.com/watch?v=y_1Kg45APko,</a> YouTube video for calibrating the z-offset.&nbsp; Everything went well with the installation and the firmware customization and upload.&nbsp; I’m pretty sure I’ve got the wiring correct.&nbsp; The BL Touch self checks and doesn’t show any faults on power up.&nbsp; The issue I have is during the z-offset calibration one of the first things you do is home all axis.&nbsp; When I did this, my nozzle crashed into my bed.&nbsp; I figured this may be normal since during installation you disconnect the z axis switch and haven’t calibrated it yet, so I raised the z axis manually through the menu and proceeded with the calibration.&nbsp; The rest of the procedure went well.&nbsp; I wrote the new z-offset to the EPROM and confirmed it was written correctly and stored it using M500.&nbsp; I set it as active using M501 and then read the settings with M503 and everything checked out.&nbsp; When I homed axis again, nozzle crashes into the bed again.&nbsp; Same thing when I issue G28 through Simplify3d.</p><p>Any ideas what could be going on...?</p>]]></content>
