Tronxy X3 Bed Enlargment

thingiverse

Hi everyone! Hope my instructions are relatively straightforward. Any tips are greatly appreciated. Enjoy! This Tronxy X3 modification allows for the installation of a larger heatbed, up to approx 330x330 mm (same size as the X3S). NOTE: The custom parts are a work in progress so check back here for the updated versions. X/Z AXIS: The mod involves relocating the Z-motors to the outside of the 2020 uprights. This means the x axis must be extended to allow for x motor to sit further left (Using the custom x motor mount in the files section). The lead-screws will now need to be supported as they sits outside the frame. I have designed simple holder that can take a standard bearing to align the top of the lead-screws. (Lead-screw support left and right in the files section). The extruder can now be mounted quite easily on the right z carrriage. (See photos for better understanding.) The 'x-tensioner' component (not shown in pictures) has also been customized fully to fit between the right end of the x axis and the extruder motor. However the tensioning functionality has been removed as space was tight and retensioning is only needed from time to time. (part found in files section). Y-AXIS: The y axis is a work in progress. In its current state there is only enough y travel to use approx 70% of the bed (I aim to use the full 330x330mm bed). The motor may need to be re-orientated as well as some extended 2020 extrusions. I will keep updating as i go. FURTHER NOTES: -Any other printed parts you see in the attached photos that i did not mention (Z motor mounts, z carriages, 2020 braces etc) were found here on thingiverse uploaded by various talented X3 owners. -Bigger PSU needed to satisfactorily heat bigger bed. -Mosfet needed to accomodate PSU for safety. -Longer belts may be needed depending.
