Re: Bob's Super Simple 4th Axis

Re: Router tip does not reach cnc bed or spoil board

There are many solutions: 1. Try lowering the router in the clamp if possible. 2. There are holes of the sides of the gantry legs that can be used to adjust gantry height. Are there any empty holes beneath the holes being used now? 3. What you are doing now...raise the stock with scraps, or a thicke...

Re: Intermittent movement in Z axis.

OK John, A couple things to check: 1. Check the tightness of the screws holding the coupler on the stepper motor to the Z drive screw. These become loose.

You can control the depth if desired by setting the flat depth here: depth.jpg (Don't get confused by the start depth I'm using in this clip. Usually it's set a 0 inches.) Another note: Whenever you convert a bitmap to...
