E3D V6 Hotend mount for Biqu B1

prusaprinters

<p><strong>Work in progress (?)</strong></p><p><strong>I get heat creeps with this build and constant clogs. Apparently the hot end cooling is not sufficient.&nbsp;</strong></p><p>&nbsp;</p><p>This is a simple mount for the E3D V6 hotend for Biqu B1 printer.&nbsp;</p><p><strong>tl:dr</strong></p><p><strong>Print both parts, drill the top metal plate, assemble back using 6x M3 nut, 2x M3x6 screw and 4x M3x10 screws.&nbsp;</strong></p><p>&nbsp;</p><p>&nbsp;</p><p>Original hotend can't be run at ABS temperatures (or even PETG), also it has it's own issues (mine clogged few times and even cold pull didn't helped), so it is a reasonable to switch for something better.</p><p>The Biqu hotend had threaded holes for M3 screws at the top, while V6 expects a kind of collar to hold it. That's why it is needed to drill new holes in the plate.&nbsp;</p><p>I provide a template for you to print and glue on the plate, to help you mark the positions. Print the Heizblech.pdf at 100% scale (no "fit to page" or anything), or use DXF directly. Second PDF provides you the dimensions in readable version.&nbsp;<br>&nbsp;</p><p>Once you got the holes right, print both the halves and install the hotend.&nbsp;</p><p>&nbsp;</p><p>You can leave the heatblock from Biqu, and just screw the heatbrake with heatsink into the block - that way you don't have to fiddle with heater cartridge and sensor.</p><p>Hotend fan needs to be installed outside now (due to space constraints), and you also need new fan duct (work in progress, gonna provide one soon).&nbsp;</p><p>&nbsp;</p><p>Be careful when disassembling and reassembling the hotend - the PCB is very fragile, but the threads in aluminium are not too robust either - I overdid it twice and had to put longer screw and nut on the other side to hold it properly.&nbsp;</p><p>You need to move hotend fan outside too - the original screws are long enough, but you need 4x M3 nut.&nbsp;</p>
