Tevo Tarantual Pro Stability Modifications

thingiverse

I found the build plate stability lacking, as it only supported 1/3 of its travel. I added a 20x20 extrusion of 250mm length at the rear, attached to the frame with "2020 Profile 40mm Corner Bracket 20mm x 40mm." This moved the original 20x40 extrusion forward by 20mm. A new y-axis extrusion was brought in as the original one was twisted and mounted using filed-down "2020 Profile 20mm Corner Bracket 20mm x 20mm". I also used additional 40mm corner brackets on the forward extrusion to create a nice square frame. Two more were added to hold the Y axis and keep it straight and square. The electronics box and power supply no longer fit, so I designed an attached electronics box with fan support and mounts for simple mosfet boards that can be purchased on aliexpress or anywhere. One mosfet controls the fan, while the other, via a current-adjustable power supply, lights switches an LED COB strip for the enclosure light. I used a level to ensure the y-axis is straight and level, paying attention not to screw it too tight down. This resulted in a very straight and level print bed without the curve that the original Tevo design gave me. A power supply box mounted behind the right Z axis is needed; see my design or the one it's remixed from for one that suits. See https://github.com/mwinters-stuff/Marlin for my marlin configuration.
