Titan E3D UM Mount for flat nema stepper

youmagine

The mount is designed to work seamlessly with UM + or other printers featuring identical XY rods configurations. To minimize print area loss, I utilize a small flat stepper motor. This design choice reduces the Y-axis loss by approximately the thickness of the motor itself. However, due to the motor's shorter threads, I had to employ the stepper distance modifier. A few millimeters of clearance between the motor and Titan require an additional attachment. I strongly recommend using nylon nuts, as the motor tends to become very warm, reaching temperatures around 60C. The mount is a straightforward design that utilizes four screws provided with the Titan. The upper two screws, which are longer in length, use a distance plate that also serves to secure the wires in place. One of the lower screws passes through the bearing cylinder; therefore, I suggest installing it before inserting the bearings. The hotend is positioned at the same height as the standard UM hotend, requiring only a slight Z-endstop adjustment. The cooling shroud is not included, but I have been using a snap-on design that was shared previously. I am currently working on an improvement. +++ IMPORTANT +++ It's essential to note that the flat stepper motor I use has a rated power of 1A. In contrast, the standard Nema 17 motor for UM extruder is significantly higher (up to 2A). If not corrected, the smaller motor will overheat, causing problems with the extruder. To mitigate this issue, I reduce the motor current in Cura's start gcode using the following command: M907 X1100 Y1100 Z1100 E850 *** *** *EDIT* New elements have been added to the design. The flat stepper motor cannot run reliably without heat sinks; therefore, a couple of them have been attached. Additionally, a new hotend fan cooling bracket with print cooling fans mount has been integrated into the setup. To use this configuration effectively, set Cura's Machine settings property "E-steps per 1mm filament" to 350. A retraction distance of 1.5mm with a retraction speed of 25mm/sec works perfectly. To enhance cooling performance, I have added two 12V 40mm fans in series and connected them to the standard UM 19V output. This setup functions well even when operating at minimum 40% power for the fans. Stepper: http://goo.gl/XeVZUk
