Railcore II 300 ZL X-rail Height Adjuster

thingiverse

The STL scale is 10 times normal, so be sure to scale it down to 10% in your slicer. Sorry I'm unable to easily adjust this as I lost my f360 timeline, but it's a breeze for you to compensate on your end. For those of us who struggle to get the Railcore perfectly square, this x-rail adjuster did the trick for me. This is based on the excellent XRAT tool by jslaker, but I was unable to get that version to fit properly with the 713maker halo. There are two versions available - one for use with the 713maker halo, which has a small recess in case your construction is like mine with the halo slightly inward of the extrusion, and another version without the halo that has a smooth back. You can mirror the STL as necessary. This uses the longer McMaster Carr part number 94180A333 Tapered Heat-Set Inserts for Plastic, Brass, M3 x 0.50 mm Thread Size, 6.400 mm Installed Length. These will work better than the shorter ones because the part relies on set screws pressed into the rails. I made these for the Misumi rails, and I'm not sure if they will work on others, but probably will. I only needed to make adjustments to the right side of the printer after centering the rails on the left. Adjustments may be necessary on either side of the rails, though the x-endstop may need to be redesigned in that case. For printing, orient the open side up and leave the little parts that set in the rail tracks as they help grip and protect the rail at the same time. Be sure to remove all bolts and nuts except for the end that doesn't require height adjustment.
