I have been working to create a growler carrier utilizing CNC box type construction. I wound up designing in Easel, mainly because of the ease of creating dog bones. I am having an extremely hard time getting my tolerance to work out. Somehow, I believe, I cant get my machine to be as accurate as needed. As an example, within Easel I specified a box .5 x 1 to be pocketed and it comes out .462 x 1.01.
I have ran the circle, square, triangle test and it comes out just fine.
I have checked the set screws on the drive gears, I measured the tension in the y axis belts to be just over 4 lbs when 1 inch off of the rail. Something I have never seen described is how much force is need to move the gantry when free of the belt? I wonder if my v-wheels might not be adjusted correctly?
Any help would be appreciated.
