Lines.... Help

[ChrisAlb]

There should be a small amount of up & down movement in that brass roller with a noticable soft "spring" tension lifting it up. How about that Z belt? It seem tight, clean and OK?

[flemingswoodworks]

brass roller def feels stiff...the belt looks almost new. how tight should the belt feel..should it be real tight or just slightly

[ChrisAlb]

Check for any obstruction around that roller. The belt should be tight with just a little side to side play. Also, you may want to check the screws that hold the Z motor and make sure they're tight.

I know you said you adjusted the Z truck bearings. With the unit turned off, make sure there's no play at both the top and bottom positions. If memory serves, that bottom right bearing being ever so slightly loose was a cause of lines for some folks.

ChrisAlb, good to see you back on.

We had a Good Visit today, Chris looks Great.... Life on the Road is agreeing with him.

As for the lines....

1st possible cause is the Y Roller Rail Bearings have one bearing out of top dead center letting the head tilt. To check Grab the whole head assembly and try to twist clockwise then counter clockwise. You would feel the looseness.... Remember the 2 top Y Roller Bearings need to be adjusted to Top Dead Center or the most closed position.

2nd possible cause is the Z Rail Bearings and checked the same way.

3rd possible cause is the screws holding the Z Motor to the machine or the 2 screws inside the gearbox holding the gearbox to the Motor are loose.

4th possible cause is that the screws going into the bottom of the smooth 4 corner posts are loose letting the head raise on sawdust on the board.

@chrisalb nothing is loose at all I took the whole z assem off again and reinstalled it with same results..

@Digitalwoodshop I went through all your suggestions and all looked good...I snuged the screws tight on the 4 smooth corners and am running a test carve now..will let you know the results....

just a question on cost if anyone knows the answer. how much does it run to ship these things back and forth to CW

I don't know is CW bumps up the price shipping it back to you but I have shipped a few of these across the U.S. and they cost between $75 and $85 ground UPS if you buy and print label on line.
