Anet A8 Titan Aero X Carriage

thingiverse

This is a remix of [Original Prusa i3 MK2 E3D Titan Aero Upgrade](https://www.thingiverse.com/thing:2192480) tailored specifically for the Anet A8. You will need an appropriately sized fan duct from the original as well, which can be found in the default Anet motors using the [39mm duct](https://www.thingiverse.com/download:3470575).\r\n\r\nThe primary modifications made were to the belt holder and channel to align with the 16 tooth gears supplied with the A8. You will likely need to use glass fibre reinforced belts as the supplied ones may be too thick to fit comfortably. It is also recommended that you pair this upgrade with Leo_N's [Anet A8 X-Idler Mounts](https://www.thingiverse.com/thing:1919544) due to the slightly wider spacing of the Anet A8's X rods. Using the Anet supplied X carriage may cause binding of the linear bearings, resulting in reduced print quality and increased wear on the motors.\r\n\r\nThe Anet board seems incapable of supplying the correct current for anything other than the supplied motors. If you have the older version of the Anet board, you might be able to use the smaller motor available for the Aero. Since my board lacks adjustable trimpots, I was unable to get the E3D pancake motor or a clone to work properly. As such, I had to use the supplied Anet motor with the 39mm duct.\r\n\r\nFirmware settings provided are based on the use of [SkyNet3D](https://www.facebook.com/skynet3ddevelopment/)/[Marlin](https://github.com/MarlinFirmware/Marlin).\r\n\r\n**Configuration.h Settings:**\r\n\#define DEFAULT_AXIS_STEPS_PER_UNIT {100, 100, 400, 496}\r\n\#define DEFAULT_MAX_FEEDRATE {400, 400, 8, 1.5}\r\n\#define DEFAULT_MAX_ACCELERATION { 1000, 1000, 100, 1000 }\r\n\#define INVERT_X_DIR true\r\n\#define INVERT_E0_DIR true\r\n\r\nAfter making these changes, recompile and flash the printer with the new firmware.\r\n\r\nFor DEFAULT_AXIS_STEPS_PER_UNIT, the last value represents the Extruder Stepper. Your value may differ, so use a [guide](http://reprap.org/wiki/Triffid_Hunter%27s_Calibration_Guide#E_steps) to help you determine the correct setting. If you use M92 Exxx to set the value, you may need to employ the Load Settings option on the LCD for the changes to take effect.\r\n\r\nThe maximum feed rate is approximately 1/25th of the original setting, which initially seemed low but has not caused any issues while printing at 40mm/s with a layer height of 0.32mm. Any higher speed resulted in my [rigid.ink](http://r.sloyalty.com/r/vGN2toWSdWdl) (referral link) PLA at 180C not feeding accurately due to the gear grinding through the filament.\r\n\r\n**Note:** M8 proximity probes do not provide sufficient detection range for the Aluminium heat bed, and no larger sensor fits in the mount. I plan to create an attachment for M12 or larger probes when time permits.\r\n\r\n**Edit 2017/09/011:** The first sensor mount is now available, which fits the [Tronxy XY-08N](https://www.gearbest.com/3d-printer-parts/pp_591321.html) and similar models. It also allows for the use of an [E3D Volcano](https://e3d-online.com/volcano-sensor-cartridge-block) hot end, thanks to its adjustable design. Cylindrical mounts should follow soon, along with firmware offsets.\r\n\r\nAs a side note, I have switched to using [Simplify3D](https://www.simplify3d.com/) v4 and am very impressed. Out of the box, it prints faster (over half an hour quicker for this model at 0.24mm and 40mm/s) with better quality than Cura 2.6.2 that I had spent weeks tweaking. I do miss the ability to print directly to OctoPrint, but I am sorely tempted to keep [Simplify3D](https://www.simplify3d.com/), despite its high cost of approximately 5 quid less than what I paid for the A8.
