This is the single extruder version of my other Anet A8 Carriages here: https://www.thingiverse.com/thing:2766701 https://www.thingiverse.com/thing:2734717 BlTouch version here! https://www.thingiverse.com/thing:2873811 Get the chain here: https://www.thingiverse.com/thing:3179124 Get the chain here: https://www.thingiverse.com/thing:3179124 Video of it in use: https://www.youtube.com/watch?v=YpmkxxurtH0 And timelapse of it printing part of the Boombox https://www.thingiverse.com/thing:2788789 https://youtu.be/YOHUB8JxVU8 The cap is setup to use 40mm long M4 hardware. I used socket head cap screws for mine. There's .STL and the better .AMF that CURA accepts as well as versions with and without sensor and with or without a mount for a chain. This fits most standard chains on Thingiverse but I like this one most: https://www.thingiverse.com/thing:2193695 and am listing this as a remix. I have included that chain file. For part cooling I recommend Mistral 2.1A 4.5 from https://www.thingiverse.com/thing:2121279 For mounting the belt I used https://www.thingiverse.com/thing:2264558 This is 100% Designed from scratch in Solidworks 2016. Choose your part and print! 18mm Sensor and chain mount 18mm Sensor with no chain mount 12mm Sensor and chain mount 12mm Sensor andno chain mount 8mm Sensor and chain mount 8mm Sensor and no chain mount No sensor with chain mount No sensor, no chain Smaller sensors put it closer to the extruder but tend to have shorter detection distances. To use this you must be on Skynet/Marlin firmware and make the changes below: Get the firmware from https://github.com/thijsk/Skynet3d For the 18mm probe set : define X_PROBE_OFFSET_FROM_EXTRUDER 0 // X offset: -left +right [of the nozzle] define Y_PROBE_OFFSET_FROM_EXTRUDER -28 // Y offset: -front +behind [the nozzle] define Z_PROBE_OFFSET_FROM_EXTRUDER -0.5 // Z offset: -below +above [the nozzle Set this to your machine. I used a .5mm thick print put between the bed and probe with the nozzle touching the bed to start.] For the 12mm probe set: define X_PROBE_OFFSET_FROM_EXTRUDER 0 // X offset: -left +right [of the nozzle] define Y_PROBE_OFFSET_FROM_EXTRUDER -23 // Y offset: -front +behind [the nozzle] define Z_PROBE_OFFSET_FROM_EXTRUDER -0.5 // Z offset: -below +above [the nozzle Set this to your machine. I used a .5mm thick print put between the bed and probe with the nozzle touching the bed to start.] For the 8mm probe set: define X_PROBE_OFFSET_FROM_EXTRUDER 0 // X offset: -left +right [of the nozzle] define Y_PROBE_OFFSET_FROM_EXTRUDER -20 // Y offset: -front +behind [the nozzle] define Z_PROBE_OFFSET_FROM_EXTRUDER -0.5 // Z offset: -below +above [the nozzle Set this to your machine. I used a .5mm thick print put between the bed and probe with the nozzle touching the bed to start.] And the travel limits are: // Travel limits after homing (units are in mm) define X_MAX_POS 240 define X_MIN_POS -10 define Y_MAX_POS 230 define Y_MIN_POS -13 define Z_MAX_POS 230 define Z_MIN_POS 0 You also must set // Set the boundaries for probing (where the probe can reach). define LEFT_PROBE_BED_POSITION 20 define RIGHT_PROBE_BED_POSITION 200 define BACK_PROBE_BED_POSITION 200 define FRONT_PROBE_BED_POSITION 20 See my PDF offsets guide here: https://goo.gl/fJyuiC It is written for my dual extruder carriages but the Z probe offset still applies here for those using a probe. Here's a crapCAD schematic of the optocoupler board I made to run the 12v probe completely isolated from the RAMPS board. Updates: - 2/11/18 Changed fillet on fan mount to make it easier to print.
