Running a flattening pass on my spoilboard and the speed setting on the Makita router won’t stay constant. Anyone else seen this? Is there a fix?

I don’t have a Makita but a Google search makes it sound like this is a common issue.
I see fixes involving tape, tightening screws, clips for purchase.
Since I don’t have one, I won’t make a suggestion, just leave what I searched for:

Thanks, found this on Printables - can’t hurt to give it a try and see if it works…
If the dial itself isn’t moving (possible that it is moving, but unlikely IME), then there are some likely culprits:
Is there another device on the same AC circuit? Things like air compressors, refrigerators, air conditioners, vacuum cleaners etc.(pretty much anything with a motor) can make the router slow down when they cycle on, and speed up when they cycle off. Space heaters can do the same thing
Are you taking too big a Depth of Cut (DOC) when you are surfacing? With a large diameter bit, even 0.5mm DOC can put a huge load on the router. Try taking 0.2mm at a pass and see if the router stays constant speed.
Note that the spoilboard surface is uneven (hence why you are surfacing), so even if you start at 0.2mm DOC, there may be places where you end up taking a much bigger DOC. It’s always best to identify the highest section of the spoilboard, and start surfacing with that point as your Z=0 point.
That’s fancy, I use a bit of electrical tape.
