X Axis stall 289

[Gerald Bennett]

Haven't seen a 289 stall thread (sigh)

Setting up a project and when it went to measure the board length it moves a small distance and stops, since it moves I don't think its the gear but havent opened it yet to try to look at them. If I push the front belt by hand the back belt also moves. Head pressure is 75 lbs.

The sandpaper belts don't appear to be rolled under but the bck one IS nearer to the keypad than it used to be. DO you all think the belts could be cauing the problem and what would cause the belts to move to the keypad side? I check the head pressure before every carve and haven't had a problem with pressure

Edit: Ok, answered this one by playing around. A 289 error can be caused by something jamming the roller, in this case the edge of the sandpaper belt had started to separate along the seam and was catching on the plate by the brass roller. In the process of trying to see exactly what was happening the belt started to catch and tear jamming the rollers. I tired tearing off a strip as was mentioned in other posts to make a temporary fix until I can get new belts but they just keep on catching so I am down until new belts can be ordered. Still don't know why with the head pressure being monitored the belts moved over so would appreciate other ideas in that department so I know what else to watch for.

I have also had belts koving sideways all of a sudden...

The belt rollers can be adjusted to some extent, which may help.

I believe the belts can also move due to things like uneven roller pressure (e.g. caused by slight warping of the piece of wood). Please correct me, anybody, if I'm wrong.

You are correct.
There are, also, other things that could cause the belt to shift.
1) Long boards, with no external roller support (beyond the machine). Without them, you accent any defect in the board.
2) Dirt under Belt.

In my opinon 3 things cause the forward belt to creep toward the keypad and roll under....

1. Boards placed in the machine at a SLIGHT Angle.

2. Too tight head pressure so the belt is pressed so hard on the paper tray that it stretches.... Since we do boards up to 11.25 most of the time... The stress is not equal and the bit flag end does not get stretched as much... So we end up with a Funnel shaped belt that migrates toward the keypad and rolls under....

3. I think as the sand paper belts age and break down and get broke in... Like a pair of Leather gloves.... They expand.... to a cone shape and roll under.... I get about 9 months out of a set of belts.... could be more...

That is my 3 cents....

Gerald,

Take the belt off and turn it around so you can use it until your new ones arrive.
