TronxyX5SA pro direct drive
Description
Great printer, shame about the dribbling. I blamed the long Bowden drive and the slicer. The real issue is the hot end heatsink is far too close to the backplate, poor cooling and heat creep. It can be moved away by 10mm using spacers or M3 brass standoffs (male - threaded end will need trimming). You will need to file the shroud - see picture. I'd gone too far so here is my direct drive design. You need to chop off the cable chain mount (sorry) and use the (excellent) Tronxy "titan" extruder. Change the motor for the lighter 17HS4023. M5x45 button head bolts fix this to the X carriage and the spacer gets better belt alignment. Filstand holds the wires (spiral wrapped) clear, use cable ties at both ends. A festo fitting holds a length of PTFE to guide filament. Also included are belt fixings, you can push something through the holes to retain (mine haven't slipped in use) and a cable spool holder remixed so the nut passes over a M8 bolt head (drill the Tronxy holder and fix the bolt with nuts both sides). Finally the Tronxy slicer retract speed is far too fast, set this to 25 - 40 mm/s. Otherwise the slicer is fine.
