Mlapp’s idea to use conduit instead of the drag chain seemed reasonable at first glance – but the good (tough) stuff is much stiffer, than the Top Mount Cable Chain Remix by Vetterick. Hopefully at least the temperature resitance of the M4P material will be an advantage now. On the other hand: My X gantry (Filament PM PETG-CF) had already deformed, the Y gantry (PC/ABS) cracked and even the ABS-T parts had suffered from the heat. And not for the geometries I had designed. An added thermometer showed me, that I couldn’t reach, what the material wanted – at least not in winter. Then there was the temperature inside my enclosure. That’s the reason I went for that air deflector. …then I realized, that my hotend cooling fan was sucking air from the direction of the part. Couldn’t get the layers to adhere at first… the ♜, maybe?) So I’m still limited to 300 ☌ at the nozzle…ĪBS-PC, this time from M4P. It worked first, then at some point I had to revert to a generic cartridge thermistor again – no idea why. And the T-D500 was at some point rejected by my SKR 1.1 board. At first I failed reading the descripton properly – the Trianglelab Matrix bimetal heatbreak does not fit the Hemera (instead you can buy dedicated Hemera heatbreaks from them, if you want to). The SKR board was updated to Marlin 2.0.7.2 during the revision. And a single belt (4 meters instead of two times 2 m) can be used now. The whole carriage is a lot more compact now – the last one was great to service, but I think I just overdid it with the accessibility (at the cost of ringing in my prints later on). The 2020 extrusion is gone, as the MGN12 rail should be more than solid enough – there are still two angle brackets included, though. Steel nozzle and brass heater block are mounted right away, a fan deflector ( Anti-warping air deflector for PRUSA i3 MK3S by Hans_W) was part of the design from the start. The heatbreak is polished properly ex-factory now (as you would expect from E3D in 2021) – so hopefully I won’t have to tinker anymore here, like in the past. I kept the threaded sleeves from the last iteration. The parts are chamfered now and received imprinted / embossed versioning. This time I ordered some extra parts, especially an extra MGN12H clone, to try out everything before dismantling the X5S. With additional vitamins, like the X5S Frame by DKDaigle. They were all integrated into a single file. □ First came the pre-order for the re-lauched Hemera, then came the overhaul for my previous designs. And in the meantime I had learned some additional tricks in embedded programming – which also rubbed off on OpenSCAD. (In the meantime I took a pause from tinkering with the BeX5S, got myself a welder and so on – but that’s a different story…)Īt some point I saw, that Hemera was getting available again. Had I known, what they were up to, I would have waited for that one! And to boost my frustration: Once I saw Hemera, E3D’s supply chain crumbled beneath COVID 19 and it took them more than a year to re-launch their product. ![]() ![]() Then there was the release of E3D’s Hemera, which I didn’t see coming. And I just couldn’t get the Sanjiu BMG to print flexibles reliable enough. It was too high, so the lever for the drag chain and the reverse Bowden tube were large. The single Z motor conversion turned out to work great – but my latest X carriage had some flaws, that surfaced afterwards even more. ![]() So what happened before that and within the month afterwards? I’ll try to sort this here… On February 20th I uploaded my (then untestested) CoreXY gantry set for the X5S / X5SA to YouMagine and Libre3D.
