Wanhao/Maker Select i3 Ramps Conversion for OSOYOO Ramps Kit with 2.8" Touch Screen

thingiverse

2/17/2017 I tweaked the LCD adapter to enable printing without support material. 2/18/2017 I modified the Melzi to Ramps adapter so that power cables are better aligned with the PSU and the fan is positioned for optimal cooling of the stepper drivers. 2/26/2017 I added a USB socket plug, allowing access to the main RAMPS USB connector. This project was based on the Osoyoo Ramps kit purchased from Amazon for $69: https://www.amazon.com/OSOYOO-Controller-Combination-MEGA2560-RAMPS1-4/dp/B01J9ZVPZU/ *A few users reported that the above package is no longer available. Here's a second source that looks identical: https://www.amazon.com/gp/product/B01JA5EQJG With this link, you'll need to buy the LCD board and the RAMPS board separately. They provide a link to the same osoyoo page I used - so this is a good sign. This conversion is specifically for converting a Wanhao Duplicator i3 or MonoPrice Maker Select V2 i3 to Ramps with touch screen using the kit linked above. The parts I made include: MKSTFT28_Adapter05.stl - This is the mount for the LCD touch screen, USB, and Card Reader. Melzi2RampsAdapter02.stl - This adapter allows you to use existing screws that held the Melzi board in place to hold the new RAMPS board instead. 4mm_spacer.stl - Use these between 20mm stand-offs from the i3 enclosure and the LCD board. (optional). Print 4 of these. (takes about 5 minutes to print 4). USBPort_for_MP_Case01.stl is an optional part. Parts needed: 4 qty 15mm M3 screws for LCD 4 qty 20MM M3 standoffs (Vinyl or Brass) 8 qty 10MM M3 screws for Melzi to RAMPS mount 4 qty 10MM or 15MM standoffs to raise the Ramps board. Assembly: Print the 3 parts attached. Disassemble your metal enclosure and remove the Melzi board. Carefully label connections before pulling them from the Melzi board. Before full assembly - Configure and test the Ramps board (get that working first). Guide is here: http://osoyoo.com/2016/06/30/mks-1-4-3d-printer-board-marlin-firmware-installation-guide/ Ramps Board - Do this after programming and testing your Ramps board. Eye up the location of the USB socket on the ramps connector and mark the case with a sharpie (please carefully measure before you cut). Remove all electronics from the enclosure for safe drilling (You don't want metal shavings on your electronics). Drill 4 holes ~7 to 8mm in diameter at the corners of the square you measured. They should be spaced 22mm apart horizontally and 23.5mm apart vertically. Use a jigsaw or hacksaw with a metal cutting blade to cut a straight line between each hole. It should open up to a rectangle once all 4 lines are cut. Pop in the printed "USBPort_for_MP_Case01.stl" part. The fit should be a snug pressure fit. Use Hot glue if the fit is loose. This conversion pairs nicely with this backplate for 80mm fans: http://www.thingiverse.com/thing:2137022 Post-Printing Tip! - Pull the little heatsinks off on your Melzi board and place them on the Ramps board's stepper drivers.
