Get the chain on the biggest cogs, front and rear. The cross chaining position. Reset your low limit screw to move the der cage so the jockey wheel is aligned right under the large cog. Then turn the screw another half turn to move the jockey wheel towards the spokes. This will cure the problem for the large rear cog. Should help the rest, too.
To make sure the extra half turn isn't too much, on the stand, shift 3-2-1 on the cogs several times. You want to make sure the chain doesn't jump into the spokes. bk
