MicroCube with autobed leveling function-Titan Extruder

thingiverse

Thanks @Stargrove1 for this nice design. I have made lots of modifications as below: Added nema 11 as Z axis with an 8mm threaded rod. Used a 220v 100W silicone heater as heated bed, paired with a 2.5mm aluminum plate. Installed LM8LUU bearings on all axes (X, Y, and Z). Switched to aluminum rods for the bed and completely redesigned it. Mounted a titan extruder and designed a custom mount for it. Added an autobed leveling function, utilizing an optical endstop and a 1.5mm allen key. SOME NOTES: *** X Axis Tensioner: It requires two M3 brass inserts: https://www.aliexpress.com/item/100PCS-M3-3-4-MM-Brass-Inserts-Double-Pass-Copper-Knurl-Nut-Embedded-Fastener/32825235531.html *** Z_Probe: You need to glue it onto the X carriage, where there is a special place for it. CA glue works well for this. Also, you'll need an 86mm tall, 1.5mm allen key or a similar 1.5mm wide Stainless rod. Be careful when gluing, making sure the allen key can easily pass through its hole. It uses an optical endstop. For more information about autobed function: https://www.thingiverse.com/thing:2551717 *** I used a 220V silicon heater for the bed with an SSR. Also, I placed all the electronics underneath the bottom of the printer, securing them with a 5mm wooden plate. A bottom plate holder was added for this reason. *** I utilized a unique aluminum rod that I had found in my old stuff as the bed holder rod. It might be challenging to find a similar rod, so I included an stp file for you to modify the bed structure according to your needs. *** The stabilizers were made with 10mm aluminum rods. You will need 110mm for shorter ones and 240mm for longer ones. *** In some parts, brass inserts were used instead of M3 Nuts: https://www.aliexpress.com/item/100PCS-M3-5-5mm-OD-5mm-Brass-Inserts-Double-Pass-Copper-Knurl-Nut-Embedded-Fastener/32822621373.html Here's a short video: https://www.youtube.com/watch?v=Jc38-6HCgBE
