Reach3d Proximity Sensor Mount for Titan

thingiverse

I wanted to have the option to have the proximity sensor on the front, closer to the hot end, which also makes using the Titan Extruder very compact and simple to mount to the gantry. Instructions: Use the Reach3d Titan Mount created by Kouruu, found here: http://www.thingiverse.com/thing:1977341 The instructions for mounting to the Gantry are different. Here are the steps: Keep the v-wheel and 1/4 spacer from the original Reach3d kit; you will use all of them. You will need one M5 25mm screw for the lower right, since it butts up against the holder. I used M5 30mm screws for all other screw holes, but you can use longer ones if you want. The screws go in order (from back to front): screw, v-wheel, 1/4 spacer, Reach3d belt idler holder, Titan 3D Printed Extruder Mount, then the nut. I ended up hot gluing my x limit switch to the side of the motor, left of the top left nut. It seems to work fine that way. At some point I plan to design something that will fit under the nut. The stock limit switch holder that comes with the Reach3d is a little too wide to fit. Print Settings: I recommend printing with supports; this model is a little tricky to print. I may come up with another design that doesn't require supports and can use bridging, but I was in a hurry to get my extruder working. I have included the Open SCAD file that I threw together in case you want to try tweaking it. Please post a remix if you do! Settings that I used: #define X_PROBE_OFFSET_FROM_EXTRUDER 25 // X offset: -left +right [of the nozzle] #define Y_PROBE_OFFSET_FROM_EXTRUDER 0 // Y offset: -front +behind [the nozzle] #define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle] I have the newer / updated motor and used the following settings for the steps (837 is the one I changed from the default reach settings): #define DEFAULT_AXIS_STEPS_PER_UNIT {78.74,78.74,406,837}
