Re: Uneven cut

Also, are all drive screws cleaned and properly lubricated? If not, it could cause the mismatched outline cut. Tramming could cure the uneven bottom, and clean up the surfacing cut. I'm still a little suspicious of those couplers... Also what feedrates are you using. Could you post your crv. file? H...

Re: Uneven cut

Be sure to check all couplers between the motors and the drive screws. The setscrews can become loose.

Re: Bob's Super Simple 4th Axis

Steve, It was an attempt to shield the gears from sawdust. It would also serve as a guide to keep the work centered. Probably not even necessary. Try it without disks.

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...
