If you did not do a PID tune, then approach this temperature slowly, exceeding 295✬ may permanently damage the thermistor.Īs the components of the hotend will expand as they get up to printing temperatures, the hotend must be re-tightened while hot to prevent leaking of plastic. Please note that not all firmwares support autotune, and you may need to tune manually. Run M303 to autotune your PID - check out Thomas Sanladerer's video guide for more information.PID Tuning ensures that the hotend gets up to temperature correctly, with minimal overshoot and oscillation.

The E3D-v6 Firmware Configuration section shows how to implement this for the supplied thermistor sensor on a range of common firmwares. Measure the new distance to the mark if you do not measure 20mm after extrusion has finished, you may need to tweak this value accordingly.Įnsure that your firmware settings are correct for the hotend's temperature sensor. To test your value, mark the filament 120mm from the extruder then extrude 100mm slowly. Standard motor steps / rev = 400 for the motor that is supplied as an option with Titan.Steps per Unit (Extruder) = Motor Steps * Micro-stepping * Gear Ratio / (Hobb Diameter * Pi) This is not required for 3mm filament.īefore running the extruder, updates may need to be made to the firmware for both the extruder and the hotend.Įnsure that the extruder steps per mm value is correct in the firmware so that your printer extrudes the correct ammount of filament.Īs Titan uses a known gearing ratio and a consistently machined drive gear, we can offer a fairly accurate steps / mm set-point. Without this, the filament risks coming off the hobbed area of the extruder. This will provide guidance for the filament. When the extruder is ready to use, ensure that you put a piece of 4mm OD, 2mm ID PTFE tubing into the hole in the top of the idler. An early version can be identified by the fact the hole for the motor shaft does not go all the way through the heatsink. The early version of the 1.75 standard heatsink also requires a nylon spacer between the idler lever and the heatsink.Slide the idler lever onto the motor shaft, ensuring that the spring locates onto the bump on the back of the idler.In the best-case this will be a waste your time spent looking for it, worst-case it may hit someone in the face. Failure to do so can cause the spring / screw to pop out and fly to the other side of the room. Warning: Do not compress the spring without the lid on, and always ensure the idler tension is set to minimum before removing the lid.Drop this assembly into the nut-channel in the extruder body.Locate the spring around the threaded part of the screw.Screw the M4 nut all the way onto the M4 screw or thumbscrew.Otherwise they are functionally the same, so the choice is purely your own preference. The thumbscrew allows you to adjust the tension without tools whereas the button head does not, however it is more compact. An M4 button head screw (left) or an M4 thumbscrew (right). There are 2 options for adjusting the tension on a Titan. Here is a list of through-hole mounting thicknesses and associated screw lengths & spacer thicknesses you will need.If you run into problems with the screws being too long, you will also need a customisable spacer.If your mounting circumstances requires more than 2mm then you will need to use the longer mounting screws.If your mounting circumstances mean the extruder will be held less than 2mm off the face of the motor, you need to print a customisable spacer.The E3D Titan bracket sold in our store is 2mm thick, the model of this part can also be downloaded from Thingiverse.This ensures that the pinion gear clears the face of the motor. The spacer must be at least 2mm thick.When installing a Titan, be it with and Aero hotend or otherwise a spacer is always required between the motor and the extruder body: It only needs to be tightened up hand-tight. Screw the Aero heatsink onto the heat break by gripping the heatsink in one hand and the heater block in the other.
