			<content type="html"><![CDATA[<p>10 min?&nbsp; That would have been peachy.&nbsp; But 22min to get to 100°C was tedious.</p><p>And my model has been sliced by then anyway.&nbsp; For me slicing is part of the iterative design/modeling process.&nbsp; I have never had the occasion to print a part I did not model. When I boot the printer I am ready to print.</p><p>Regardless, this thread was about an economical way to improve performance by utilizing some assets that are already on the printer that may have been disconnected due to a hack.&nbsp; Not time management, which is not a hack.</p><p>No worries.&nbsp; Next project, redo the crappy enclosure I made 4 years ago.&nbsp; I have some 1/4 inch polycarb that I scavanged from a fume hood sitting next to a dumptser behind the neighboring prosthetics company (a few Benjamins retail).</p><p>I am not a hoarder.</p>]]></content>

			<content type="html"><![CDATA[<p>Just out of curiosity, why is everyone so worried about heatup times. I mean there has to be many things you do while waiting. Even work on the next project. Like heartless said, you can get the file ready while it is heating. I am just curious as mine take about ten minutes to reach 65, and that is no real issue to me as I can do other things while it heats so no time is lost.</p>]]></content>

			<content type="html"><![CDATA[<p>I&#039;ve heard a lot of good things about the Hale pad, but I use a SD2 - 150mm/6in bed.&nbsp; Azerate had mentioned in the past that he had hoped to develop a 6&#039; version.&nbsp; I use an aftermarket silicone pad I bought from Azerate after my aftermarket one quit.&nbsp; With a Supernight PS (12V), SSR and a silicone pad, I heat to 97C in 3 min or just under.</p>]]></content>

			<content type="html"><![CDATA[<p>i have had both the silicone pads (stock SD4) and MK2 beds - altho I have never tried running both at once... </p><p>the Hale is far and away, leaps and bounds better. Even on a 3/16&quot; thick aluminum plate with 3mm thick mirror tile on top of that, it takes Less than 10 mins to get to operating temp... I turn the bed on, and while it is heating, I will load my model, tinker with slicer settings, &amp; slice - by the time I decide the model is ready for printing, the bed is hot and ready to go - and the heat is even across the bed, no hot spots, no cold spots - i can run stuff right out to the edge of the bed with no problems. </p><p>Oh, and i don&#039;t hoard either, <img src="https://www.soliforum.com/img/smilies/wink.png" width="15" height="15" alt="wink" /> lol&nbsp; *shoves the tote with excess parts further under the desk with her toe*</p>]]></content>

			<content type="html"><![CDATA[<p>Agreed - ish.</p><p>I had already purchased the MK2 and the rest came out of my &quot;junk&quot; bins.&nbsp; So I paid around $13, plus the cost of storage in a plastic tote in my garage for who knows how long.</p><p>I am not a hoarder.&nbsp; I say this to anyone who is around when I re-purpose someone&#039;s junk.</p><p>So, if over the years that the MK2 has existed anyone here has installed one and would like a 50 or 60% power bump for a little wiring and no tear down:&nbsp; For the cost of a $9 relay and a $20 power supply ...</p><p>Not advocating, just information.</p>]]></content>

			<content type="html"><![CDATA[<p>A while back I posted pics of my all metal gantry and extruder hack:<br /><a href="http://www.soliforum.com/topic/15488/my-big-hack-all-metal-sd3/">http://www.soliforum.com/topic/15488/my … metal-sd3/</a></p><p>In that post I was annoyed that that the new MK2 PCB bed running at 24V was no faster heating than the original equipment 12V silicone pad.</p><p>Solution:<br />Short answer:&nbsp; Connect the MK2 and the silicone pad (I left it on as insulation) in series and run them at 24V.&nbsp; Heats up in 7min.</p><br /><p>Longer answer: The MK2 bed measured 6ohm across the 24V leads and 3ohm across the 12V leads (duh).&nbsp; The silicone pad measured 2ohms.&nbsp; Wired the MK2 for 12V and connected it in series with the silicone pad. 3+2=5ohms.</p><p>20% power increase form 96W to 115W.&nbsp; Current increases from 4A to ~5A.&nbsp; That is okay for me since the the 24V supply is good for 15A and I am running it through a 30A solid state relay controlled directly from the original bed heater MOSFET on the Sanguinolulu.</p><p>Maybe should run the bed PID routine, but the glass does a good job of damping the power bumps.</p><p>Did I mention it heats up in 7min.</p>]]></content>
