<p>News, 28.03.2020:</p> <p>I have now added three version of the Extrudermount, the recent one is the one with BMG in the title, and was designed around a BMG clone extruder, but should fit regular BMGs as well.<br/> Also added the missing HEVO-X-Carriage-Adapter (RF100-Adapter), so you can screw the original HEVO-Hotend-Carriage to the RF100. Somehow that got lost.</p> <p>Happy printing, and stay safe and sound through all this! \o/</p> <p>TL;DR first:</p> <p>Welcome to my Overhaul of the Renkforce RF100!</p> <p>So, i got the hands on a totally totaled RF100 V1. Board dead, PSU dead, Hotend clogged and stuck with tons of PLA, one stepper motor dead, Y-axis bent.</p> <p>Due to having already built a corexy and rebuilding two ender 2s, i had a lot of spare parts and random stuff, so i put some evenings in, and rebuilt everything.<br/> The target wasnt only a functioning printer, but also the max build volume i could get out of this frame.</p> <p>What i did is:</p> <ul> <li>straightened the y-axis</li> <li>designed and printed an adapting piece to fit an HEVO-Hotend-Carriage</li> <li>converted to a bowdensetup (for this i took an existing design and just redid a few things in tinkercad because i just wanted it to be done)</li> <li>designed and printed new X and Z-endstops</li> <li>designed, printed, and cut a new Y-carriage to fit the Ender 2 Heatbed out of aluminium (dont do this. Just send the file to a plasmacutting facility and get a perfect carriage, and not the junk i sawed myself)</li> <li>put an Bigtreetech SKR v1.3 into this, together with 4 TMC2208</li> <li>put an original Ender 2 Heatbed into this (150x150mm)</li> <li>designed and printed an extension for the 5015 blower, so it doesnt jam into the frame before the actual hotend-carriage does</li> <li>oh, and of course added an 5015 as partcooling into the setup, but that wasnt really difficult, as this was already a part of the hotend-carriage</li> <li>threw the internal 12 PSU out, and put an external 12V/30A PSU into the setup to have enough juice to drive both hotend and heatbed at ease</li> <li>turned the heatbed-mount 180°, to get a bit more buildvolume<br/> The original buildvolume of the Renkforce RF100 is 100x100x100, which is 1l.<br/> The new buildvolume is 127x142x145, which is 2.61l, so 161% more<br/> buildvolume!</li> </ul> <p>The longer version:</p> <p>++++++++ Why? ++++++++<br/> I saw the RF100 (v2) at the german Conrad a few times, and found it too expensive for what it did (120x120x120 buildvolume, no heated bed).<br/> But as i found a V1 one (100x100x100 buildvolume), that was more or less declared dead and i thought "i could rebuild this, bigger and better" and so went with it.</p> <p>++++++++ Why bowden? ++++++++<br/> Well, direct was dead on the rf100 that arrived anyway, i had all the parts laying around for a bowden setup, and i like bowden and use it on the 4 other printers i have...<br/> ...so... why not?</p> <p>++++++++ Why an E3D V6? ++++++++<br/> I like it, all my other printer have one, so... why not?</p> <p>++++++++ Why a 5015 for part cooling? ++++++++<br/> Because it works. Also, why... ah... you get it now i think.</p> <p>++++++++ Why a SKR v1.3? ++++++++<br/> Its the future of affordable 3D printing. Its 32Bit. There is literally no reason going 8Bit for anything any more, since the SKR v1.1 is out.<br/> So, why not?</p> <p>(did i said it again?)</p> <p>++++++++ What will that all cost me? ++++++++<br/> The printer was 50 bucks in that totalled state, the SKR plus 4 TMC 2208 another 50,<br/> the E3D V6 clone 10 bucks, the 5015 probably 5 bucks, the ender 2 heatbed would probably be 20 bucks, the PSU 25 bucks, the Extruder would probably be 10 bucks...</p> <p>Lets just say it will cost some moneys.</p> <p>++++++++ Is the rebuild worth it? ++++++++<br/> What? Hell no!<br/> 3D Printing is a hobby, and rebuilding or "reboot"ing (who came up with that idiotic phrase anyway... oh, that was me...) a 3D printer is a money sink.<br/> If you want a bigger printer for cheap, go Ender 3! Or 5! Or... i dont know.</p> <p>Yeah, i totally copied that sentence over from my Ender 2 rebuild.<br/> Sue me! \o/</p>
