Are those standard Misumi brackets at the base of the MakerSlide?
The brackets are the standard cast 40mm wide brackets. They have little alignment bosses on them to align in the slots. That is handy in most cases, but I had to route pockets in the base for them.
The Makerslide is also bolted to the base using tapped holes in the center. The 4 bolts made it easy to get the rails straight. A little extra torque on the right bolt pulls the rail straight. The top plywood plates lock it in.
I have the end effector on now and was able to do a few air cuts. I have used both Repetier and Marlin. Marlin was not as smooth running. It may have been just different default settings. The motors are a little louder than I hoped. The X axis on my Hadron is super quiet and I hoped these would be similar. I guess you always have three motors at the same time, so that could be he reason.
The next step is mounting the extruder. I may just mount the Bowden extruder on top of my acrylic spool case for now.
