HI Leonardo, Yes I have and I actually got very far in implementing it. I am using the Mesa 7i76e to control and Peter helped me convert the spindle output to a standard analog out that I could control with M68 but I need a way to scale it similarly to how spindle speed is modified as well. Unfortunately the pump rate control is a bit of an art rather than a science so it's not straightforward to program and always needs some tweaking, so rather than writing my own UI elements and implementing new hardware controls I fell back to using the spindle output.
Having it synchronized to the axis movements would be ideal but I am not sure I will have the ability to prototype that before this needs to be deployed. Do you have examples of where what is done currently?
