maybe trying to turn the pot slower?

I never touch mine anymore, I leave them as they come from DTR because I find them to be sensitive and I have a couple that deviate with heat, this is one reason why I want to go with the fixed SXD from now on.
There are a lot of good safety features, slow start, over surge protection and bleed down caps, there is also the ramp up cap that could be affecting your setting.
I know Tater May said he was having trouble with half of his a while back, maybe he can tell you how he worked it out.
This is the driver that was set at 5.0a running my decanned nubm44 that dimmed down, so I attempted to set it to 4.5a while off then checked it until I had it at 4.5a with 2 fully charged LG INR 18650 cells, they are good cells that hold 4 volts and 4 amps into 1 ohm when charged as they slowly discharge they will go down some, but way before they reach the 6.8 volt cutoff the heatsinked driver starts dropping output.
I am guessing the little pot heats up and changes resistance, they seem very touchy too me and may be fragil, so much that any more than the initial setting weakens the tension on the graphite surface, I would rather just buy the output I need fixed and skip the little pot.
The German guy, sorry I forget his name, he had trouble getting it to stabilize when we first were building our nubm44's...there may be a trick to setting it with the ramp up, but mine drops and I have not touched the pot in months. Before I touched it, it was rock solid at 4.9- 5.0
Otherwise the SXD drivers work well, my 3.4 is solid and both my living 44's work well with them, but I will happily give up the adjustable pot and pay for more fixed drivers.
I like the SXD drivers, just not this adjustable pot.

You can request Angelos make you some with multi turn pots.
