Smoothieboard X5 v1.0a frame for MakerFarm i3v

thingiverse

This is a designed plate and housing for a Smoothieboard v1.0a electronic board. The design mounts are optimized for use with a MakerFarm i3/i3v printer, utilizing the RAMPS mounting holes furnished on the wood structure of the MakerFarm i3v. The high mount location provides space on the printer frame side wall for other electronics such as a Raspberry Pi. This case design positions the USB, SD card and Ethernet connectors toward the rear of the printer, the motor connectors downward, and the majority of MOSFET switch connections atop the case. This seemed to be the most effective orientation for use with the MakerFarm 8-inch i3v printer. The given design is tailored for an X5 board purchased without connectors. Due to their compact size, Euro-style screw terminal blocks were used in all power and MOSFET switch connector positions. To simplify wire installation and ensure robust connections, contact pins, R/C hobby EC2 connector contacts or crimp sleeves were utilized on all wires linking to screw terminals. Mounting posts are included for use with cable clamps. Significant vent openings are provided for cooling purposes. In the event that active cooling is required, holes on the backside or the top could be replaced by mounts for small fans. Holes are featured in the lid for GLCD ribbon cables assuming use of the Uberclock Smoothieboard GLCD shield. Gallery pictures showcase the Smoothieboard mount utilized with the Printbus GLCD mount accessible at http://www.thingiverse.com/thing:817274. This case is a tailored version of Generic Case and Lid - Improved by Printbus (http://www.thingiverse.com/thing:643264) which is a remix of Generic case (box and lid) by davidmpye (http://www.thingiverse.com/thing:28608). It uses the polyhole and teardrop modules from the openSCAD MCAD library. It also utilizes roundCornersCube available at http://www.thingiverse.com/thing:8812, and my universal post available at http://www.thingiverse.com/thing:790359. For fit test purposes, the openSCAD file provides facilities for previewing STL models of the Smoothieboard accessible at http://www.thingiverse.com/thing:290180 and http://www.thingiverse.com/thing:414426. The case was built for use on an 8-inch MakerFarm i3v printer bought in April 2014. On at least that printer, the RAMPS mounting holes on the wood frame appeared to be slightly incorrect and were adjusted for correct RAMPS fitment. The utilized RAMPS hole pattern in the design reflects dimensioning for the Arduino MEGA2560 board, not the incorrect hole positions noticed on the i3v printer. The openSCAD file furnishes various parameters that can be tailored by the user based on the required inset clearance amount desired between the edges of the boards and the casing, and then the desired outcome from the walls of the box to the edge of the mounting lips furnished on the case.
