Titan Wades Adapter

thingiverse

This is a conversion to attach a Titan extruder to a Mendel90 or other carriage expecting a Wades extruder. This may work with other extruders/carriages with similar mounting styles. The OpenSCAD file is included here and on [GitHub](https://github.com/kc8rwr/TitanWadesAdapter). Many parameters can be changed, possibly making it work with less similar printers. This was created for a Mendel90 Sturdy variant. I have not confirmed that the relevant dimensions are the same in the Dibond or Huxley versions. I would love to hear from anyone who has other Mendel90 variants or even non-Mendel90 printers about what parameters need to be changed for using this bracket. I am including STLs for both 3mm and 1.75mm versions. I intend to print both and pre-assemble them with identical extruders and hotends for easy switching between filament sizes. I have only tested the 3mm version at this time but expect it to function identically. Notes: - When I wrote the above, I had not yet assembled the 1.75mm version. I did not understand that the Titan is meant to have a PTFE tube run through it and into the hotend in the 1.75mm configuration. Nor did I understand that the genuine V6 hotend has a hole which is for a PTFE tube. - I am using this with an all-metal hotend that requires a fan. I did not want to run an extra wire for the fan. I am not using the probe connector on the PCB. Using a Dremel, I cut the trace between the probe connector and the thermistor ground. I then soldered a wire between that pin of the connector and the positive supply for the hotend and part cooling fan. At the other end of the ribbon cable, I connected the wire that was supposed to be for the probe to ground. Then I connected the fan to what was supposed to be the probe connector and it is on whenever the printer is. This is not reflected in the first picture. - Best to add no supports via the slicer - The STL files include a thin support shell for the groove mount which removes easily - Print top/bottom halves separately - Print the bottom half upside-down so there is no bridging - Glue the halves together (ABS juice works well for this if you print it in ABS) - Run bolts through and tighten with nuts to keep it aligned and pressed together while drying - If like me, you are switching away from the original J-Head hotend as part of this upgrade, you will probably need a different part cooler fan shroud. For now, I am using one of those cheap eBay all-metal hotends that calls itself a J-Head although the dimensions seem to be the same as an E3D V6 but without the enlarged hole in the top for a PTFE tube. I did not want to design a fan shroud from scratch if I could avoid it, but I could not find a design that fit either. Fortunately dbondar has shared a parametric fan duct which with a little adjustment of parameters works great. I changed trx to 12 and try to 38. This one uses a blower rather than the muffin fan the Mendel90 originally used. It is also less bulky than the original design, which is nice because it is easier to see what is happening while it prints. I did find that with the blower I had to turn down the fan speed a bit in the slicer or it would cool my heatbed down enough to trip the thermal runaway protection. You will need to have the fan controlled via PWM, not just a simple on/off pin for this. This design was based on: - The adapter Thomas Sanladerer designed for his review of the Titan. - Wades Geared Extruder - The E3D Titan Extruder - And the Mendel90 RepRap
