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.
