HCmaker 7 Titan aero mod

thingiverse

Finally I've got it working. So... **Important notes**: I might forget something or write wrong screw length. Excuse me for that. Next time I disassemble it, I'll measure correct length. I used screws DINs from local store. You may try other screws. No problem. Extruder idler handle needs roller with U-profile. There is handle model for mr95zz instead of roller. I took roller and it's pin from cheap titan-extruder kit. I've also found useful tension spring, thumb screw and nut. There is a problem with titan-aeroheat sink and thumb screw. They do not fit to each other. Engraving tool and diamond rotary bits did it's work. New extruder means new Z-min position. I was not able to set correct Z-Endstop position. So I drilled couple of holes in side acrylic plate and moved plate lower. And z-endstop also. Keep in mind that X-beam can't move lower than wheels can move. So table also should be raised. Maybe some m3 nuts can make table springs stronger. Btw, Volcano might be easier assemble: no drilling. But there is no fan mount for Volcano yet. Later... some day later! **Print Settings** Unfortunately I'm sure some printed parts do not fit well to each other. They may require some sanding and cutting. I used ABS for all the parts. Actually ABS is strongly recommended only for fan ducts. 0.4mm nozzle is perfect. Supports is needed only for aero_idler_handle. Other parts can be printed without supports. Some infill is needed only for hcmaker_titanaero_body. Other parts can be printed 0%infill and 3 perimeters with 1.2mm top and bottom. Fan ducts can be placed on table "side down" for no-support print. Fan nuts should be printed 4 times. #Sort of BOM: **For titan-aero:** + [4010 fan 24V](https://aliexpress.ru/item/32726644469.html) or stock. + [Aero heatsink](https://aliexpress.ru/item/32862751608.html) + [big Titan gear](https://aliexpress.ru/item/32894729738.html) + [small Titan gear 22teeth](https://aliexpress.ru/item/32951876945.html) or stock mk8 fit well? + [4pcs MR95ZZ bearings](https://aliexpress.ru/item/32834097040.html) + [short Nema 17 drive](https://aliexpress.ru/item/4001084479755.html) + [short piece PTFE tube id2 od4](https://aliexpress.ru/item/10000349517368.html) + Nuts and screws: 1pcs DIN965 or M3x9 3pcs DIN7985 M3x30 or 35 1pcs DIN7985 M3x25 1pcs M3 nut 4pcs DIN7985 M3x12 **Mount** + 2pcs M4x12 + 2pcs M4 nuts **Cooling** + [2pcs 4010 blower fan 24V](https://aliexpress.ru/item/32799376487.html) + 8pcs self tapping screws 2,2x9 + 4pcs m3x8 **Hotend** + [E3D V6 heatbreak 1.75+teflon](https://aliexpress.ru/item/32639976214.html) + [Spare PTFE id2 od3 tube](https://aliexpress.ru/item/10000349517368.html) + stock heatblock, thermistor and heater. You know stock heater is only 30W? Maybe V6 heatblock with 40-50W heater or Volcano is a good idea. **Electric** You have to weld at least one angle connector xh2.54 to the printerhead board. Then crimp fan cables with xh2.54 male-connectors "2 fans in one connector". Like [that set of paired connectors](https://aliexpress.ru/item/32854734506.html) And you may like [Crimper PC-2549](https://aliexpress.ru/item/1005001364852920.html) Crimping is also possible with teeth and pliers.So tool is optional. **Firmware and printer config** This mod requires few changes or checks or calibrations: + Extruder motor Vref + Extruder direction + Extruder steps per millimeter + nozzle offsets X and Y + max X and Y coordinates possible **Good luck!
