			<description><![CDATA[<p>I can tell it&#039;s not connecting since the computer will not react to it. It should make this little &quot;beep&quot; noice when something connects and the printer should show up in device manager, but it doesn&#039;t. The power supply is healthy, fans and lights power on.<br />And I havn&#039;t replaced the board, it&#039;s still the same old badly setup board they shipped.</p>]]></description>

			<description><![CDATA[<p>So many things that could cause this.&nbsp; I would start with the basics since you replaced the board.&nbsp; Re-check every connection then double check them.&nbsp; Make sure the power supply is functioning as well.&nbsp; The board will connect through USB alone but how are you able to tell that it isn&#039;t connecting.&nbsp; Please remember I don&#039;t use a printer board and never have.&nbsp; My Rumba needs the power on in order to connect to the PC.&nbsp; I don&#039;t think that&#039;s the case for the Printer board but it&#039;s worth checking.<br />Also I know most of the connection problems I have seen are rarely caused by the board being bad.&nbsp; I have read many times that &quot;Reset on connect&quot; needs to be disabled (I Think) so check that and also that you have the correct baud rate set.</p>]]></description>

			<description><![CDATA[<p>I&#039;m saying I might&#039;ve shorted it, but I followed the instructions exactly (<a href="http://www.solidoodle.com/multimeter-testing-your-solidoodle/">http://www.solidoodle.com/multimeter-te … olidoodle/</a>). Restarted everything, changed ports, tried different computers. No signal anywhere. The board gets power via the USB but I get no signal to the computer.</p>]]></description>

The &quot;overextruding&quot; was remedied long ago, so it&#039;s not that it &quot;grabs&quot; the print and skips because of that.<br />I got a response back from solidoodle, with instructions on how to adjust the voltages so that&#039;s now taken care of. However! With this arose a new problem, the printer will no longer connect to the computer (or any computer). There&#039;s nothing wrong with the USB-cable itself, I tested with another one and the board even get power from it (green light&#039;s on).<br />I think in the worst case scenario I probably shorted something but I made sure not to poke around where I wasn&#039;t supposed to (as I said earlier, I&#039;m no engineer or have experience with electronics so I was happy there were pictures!). <br />So, thoughts about a shorted board? Would the whole thing be dead or would it be possible to just change the USB-thingy?</p>]]></description>

I did a quick test to see how far I could come this time and it went all the way to the front with no skipping so I was optimistic, but when printing it&#039;s still skipping.

			<description><![CDATA[<p>I have this problem too, but it is just a warped bed. If I do a fast move on the first layer, it might catch on filament that has already cooled or just make a line in printed material that is still hot. This is with glass on the warped bed too. So, at some point I will need to adjust the warp out of the bed. Meanwhile, if your printed object is small enough, put it to the right or left of the centerline and see if it still &quot;skips&quot;.</p>]]></description>
