I'm looking to fit a stepper motor to my horizontal mill table and wondering if anyone has any experience of setting up an LCD to monitor table speed/motor RPM. There's plenty of stuff on YT using aduino, which you have to code; I was wondering if there was a simpler way using a Stepper Motor Driver Controller PWM Pulse Signal Generator Speed Regulator thingy connected to a stepper driver? If not then I'll probably forget the RPM part, it was just that once knowing what is a good table speed is it can be reproduced as and when needed.

Search on ebay / amazon for PWM Signal Generator There are small modules with 3 digit display and UP/DOWN/SET push button switches that will do what you want. Most will generate 2 different rates. You can use this to control a stepper motor driver which has a step input.
