Hi @Bigburlybug
I had some Lowrider Drift action happening and I did 2 things:
- Make sure my starting position was truly square between y and x (y was off by 1/8 across the x - shockingly bad construction!) by adding a registration board across the top.
- Add a small strip of wood along the y track to keep the wheels running true.
Both these things made a huge difference and the machine somehow feels like it runs more solid.
Hope this helps.
