2.2KW water-cooled spindle VS. wood router - 3D art relief made easy - VFD + USB RNRMotion Mach3

#DIYCNCMill #3018CNC #Fusion360 #Mach3 #Tutorials In this video, I upgrade my home-built CNC with a 2.2KW water cooled spindle. The spindle and VFD itself were easy to install. But I'm using a cheap RNR-Motion breakout board that I couldn't find any official guide anywhere. After long time digging on Google, I finally stumble on a forum thread that showed exactly how I should connect the breakout board to the VFD: https://www.machsupport.com/forum/ind... After connecting the board to the VFD, I was able to vary the speed using Mach3 software but the frequency was very jumpy. I found out that the problem was coming from the AVI pin output wasn't analog voltage as required by the VFD. THe signal output from AVI was still PWM that go from 0-10V. To solve this problem, I bought a PWM to 0-10V Analog voltage converter module from Amazon. After input the signal from the AVI into the PWM port of the converter unit, the output was converted to analog from 0-10 V that stabilized the the frequency on the VFD and everything was working correctly from there. To mount the spindle clamp to the machine, I needed to drill a few hole on the clamp. To drill the holes at precise positions, I made a drill guide using my CNC machine and attach it to the clamp for drilling. I added the 3D models of the drill guide and also the new gantry plate for the Z axis, the mounting plate for the spindle clamp to the 3D CAD design of my CNC machine.
