Speed control for UCF

I have bought a speed controller for the new UCF and mounted it in the same box as the stepper motor controller. This speed controller does not have forward and reverse on it as standard and so as a result I have added a DPDT on/on switch appropriately wired on the output of the speed controller. I ordered the speed controller from AliExpress for just over £6 and it arrived from China in 6 days. It has now increased in price but this is a link to the controller I bought.
