it might be the modual insead of the cam, i had to get new mods for 4 of my bows, where the mod & the cam surfaces meet the edge on the mod may be thicker , the cable will ride up on that little flat surface then snap down into the groove and wear bad on the serving , they make a mod that comes to a sharp edge and doesn't permit the cable to ride up on mod it goes right in the groove & doesn't wear the cable. you can file that mod.
to a beveled edge, better to call joel and get the newest mods ,be sure to mention that you want beveled almost sharp edged mods. may not be your problem but a place to look, best if we had some pics. to look at, hope this helps & good luck.
