For a stock extruder. The original aluminum plate that holds the extruder bolts right on the face of New X gantry.stl...... one of the slots that holds the belt needs to be elongated by about 4mm with a dremel or whatever. I used 2 cuts with a hacksaw blade along each side & then break out the sliver in the middle. Print New X gantry 2.stl with supports for where the belt goes. Uses this 400mm linear bearing.....
Center between the Y gantry brackets and mount on the top of the 20x20 aluminum with M3x7mm screws with T-nuts. M3x7mm will work to mount the piece to the block as well. It's going to raise your extruder nozzle height by about 7mm. This will work with a stock X5S or one with any one of my upgrades.
If you have a longer rail than 400mm just measure between the Y gantry brackets and cut it with a hacksaw.
Added New X Gantry46mmBlock.stl & New X Gantry 2 46mmBlock.stl because the bearing block that came in (finally) was 45.4mm like the data sheet showed instead of 49mm like the first set I got when I did the Y gantry. So I have to re-print. Measure and used accordingly....
Published print & hot end cooling fans made specifically to work with this.
