Renkforce RF100 ReBoot - 161% more buildvolume!
Description
News, 28.03.2020: 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. 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. Happy printing, and stay safe and sound through all this! \o/ TL;DR first: I had that printer overhauled and printing for now more or less 6 months, and it was so good, that i right now kill that "work in progress" thing. Its done! It works! And for a better idea what you can get out of it, i added a brand new photo of a calibration cube. Oh, and since the fanmountthing was a bit finicky, i designed that into the E3D V6 mount. Have fun with this, and: Welcome to my Overhaul of the Renkforce RF100! 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. 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. The target wasnt only a functioning printer, but also the max build volume i could get out of this frame. What i did is: - straightened the y-axis - designed and printed an adapting piece to fit an HEVO-Hotend-Carriage - 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) - designed and printed new X and Z-endstops - 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) - put an Bigtreetech SKR v1.3 into this, together with 4 TMC2208 - put an original Ender 2 Heatbed into this (150x150mm) - designed and printed an extension for the 5015 blower, so it doesnt jam into the frame before the actual hotend-carriage does - 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 - 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 - turned the heatbed-mount 180°, to get a bit more buildvolume The original buildvolume of the Renkforce RF100 is 100x100x100, which is 1l. The new buildvolume is 127x142x145, which is 2.61l, so 161% more buildvolume! The longer version: ++++++++ Why? ++++++++ 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). 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. ++++++++ Why bowden? ++++++++ 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... ...so... why not? ++++++++ Why an E3D V6? ++++++++ I like it, all my other printer have one, so... why not? ++++++++ Why a 5015 for part cooling? ++++++++ Because it works. Also, why... ah... you get it now i think. ++++++++ Why a SKR v1.3? ++++++++ 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. So, why not? (did i said it again?) ++++++++ What will that all cost me? ++++++++ The printer was 50 bucks in that totalled state, the SKR plus 4 TMC 2208 another 50, 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... Lets just say it will cost some moneys. ++++++++ Is the rebuild worth it? ++++++++ What? Hell no! 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. If you want a bigger printer for cheap, go Ender 3! Or 5! Or... i dont know. Yeah, i totally copied that sentence over from my Ender 2 rebuild. Sue me! \o/ Things i have on my RF100 ReBoot, but havent done myself include: - the extended spool holder: https://www.thingiverse.com/thing:2527244 - the better cable routing: https://www.thingiverse.com/thing:2644950 - the x-carriage is from the HEVO project, but i used a slightly remixed version from here: https://www.thingiverse.com/thing:2830408 - and of course the MK3 Fanduct: https://www.thingiverse.com/thing:2852168 Happy printing! <h2><p>Want to show some support and buy me a coffee?
