Hello. I am in the middle of constructing my gantry....and I have a few questions. Having never built a cnc router I dont know what to expect in the building process. The gantry is 36 inches long and 20 inches high on rails with two trucks on each side. I have it pretty much mocked up....Also using two 4.5 inch wide x 36 inche long aluminum cross members which will hold my rails. The question is with everything mocked up when I push one side of the gantry it seems that the other will kinda lag behind. There seems to be no binding on the rails and it does track well for just being mocked. Is this to be expected? My ballscrew will be below the gantry and in the middle.( if I push from the center then it will track evenly on both sides.) Does this sound normal for not have the bottom assembly attached? Thanks. |
