Tarantula X Carriage Mods Drag Chain attachment, BLTouch, Fan

thingiverse

The initial problem I attempted to solve was how to mount a BLTouch sensor to the 'Modular X carriage for TEVO Tarantula by Elzariant' (https://www.thingiverse.com/thing:2034743). I wanted to mount the sensor in such a way that the 'Hot End' could be removed without disturbing the sensor. Following on from that I wanted to mount a layer cooling fan and duct in a similar fashion. I think the duct could possibly be improved but it has served me well up to now. My final change was to add the drag chain attachment to the top left hand spacer. All of the parts are interchangeable with the original 'Modular X Carriage' The drag chain is the one by Maxdarkdog (https://www.thingiverse.com/thing:2396718) Forgot to state the BLTouch offsets needed to add in Marlin Configuration.h They are as follows - #define Sensor_LEFT 21 #define Sensor_RIGHT 0 #define Sensor_FRONT 0 #define Sensor_BEHIND 0 I don't know why the above is such a large font. 24/01/2018 Added a modified BL-Touch holder to give a greater range of movement and a better fan duct end which is slightly bent downwards to give greater clearance to the work piece. 31/01/2018 Added a mount for a digital dial indicator to help with bed levelling. The diameter of the dial body is 57mm.
