I just bought the Super max 19/38 and while I love this machine I keep having the same problem when sanding large pieces.
This unit is especially useful for planeing and finishing end grain cutting boards. I just finished sanding a 19×44 inch yellow birch coffee table top.
The problem I have is that no matter how slowly i run the board through and no matter how little I try to take off per pass ( 1/8 handle turn per pass ) the board suddenly stalls and then the drum proceeds to dip into the board about 1/32 inch burning the area and requiring three or four passes to get it level again and remove the burn marks.
I have tried not turning the feed handle at all every third pass to make sure I am not skating above the real depth of cut but that does not seem to eliminate the problem.
Any help would be appreciated.
Thanks

Is the feed motor stopping or is the drive roller slipping inside of the feed belt (indicating insufficient tension) or the belt slipping against the workpiece?

I have the Supermax 19-38 and I’ve had this issue before. For me, it was from not having the long work piece supported enough so when more than half of it had passed through the sander, there was enough pressure on the end still in the sander to push it up toward the drum causing it to be off the conveyor which then caused it to stop feeding and put a divot in it. The solution for me was two fold. First, I added a feed roller support at the outfeed end so my work piece didn’t tip upward and stayed on the conveyor and I pushed on the piece as it went through the machine keeping minor pushing pressure on it until most of it was beyond the sanding drum. I hope this helps!
