In this episode I am testing several different Limit Switch Sensors to improve the accuracy of my CNC Router. I choose 5 different Limit Switches that I thought are a popular choice and that made sense to me. You will note that there is no capacitive sensor, this is because they usually have too much fluctuations with environmental changes. Most of the Limit Sensors are accurate to 0.015mm and it was a surprize to me that the cheap simple snap action switch was this accurate. On the contrary the hall sensor I was disappointed by. I don't mention this in the video but a possibility is that they are rated to run on 6-24V and I used 5V as they seem to function fine. I think that the accuracy was possibly lowered by this. The Metrol switch is the best and just blows away any other option. Check my site for more information: www.JBWorxstudio.com

In this episode I am updating my Mist Coolant System. I built a system about a year ago and have been using it but there are several short falls. The main problem is the needle valve delivering the Coolant. The system is pressurized and should deliver a constant flow of liquid to the Spray head but I often have to adjust it. So I am improving my Current Coolant delivery system by metering the fluid in using a peristaltic pump. I will show you the electronics needed and also how to hook everything up.

In this video I like to show you how I use my Festool Miter Saw to cut Metal. This is the Oshlun Non Ferrous Cutting Blade and it is producing very nice cuts and I am also happy with the longevity of the blade. I am sharing 5 Tips at the end of the video.

In this video I go through the steps required for the JMC Servo Motor Tuning. MY CNC Router got an upgrade from Stepper Motors to JMC Servo Motors and since then I had the opportunity to install several more on custom CNC Systems. Here is what I learned in the process of the JMC Motor Tuning and most importantly how to minimize the following or positioning error. In this video I get results using the autotune function.

In this episode I am further improving my CNC Router by adding stiffener plates to the CNC Router Z Axis. I went online for some design inspiration and found a bridge design that I liked, it is on the Sorotec machine. In the End it made only a very small improvement for my machine but maybe it makes all the difference for yours.

In this Video I am further improving my CNC Router by installing an additional Router Spindle Mount. Adding a mounting point to the top of the spindle is supposed to reduce chatter as reported by many DIY builders. There is no static movement of the spindle itself in its existing mount however that can look very different dynamically. To quantify a before and after change I like to make a measurement. So the iPhone it is but understand it is not the ideal tool for the job as its accelerometer can not measure higher frequency's. However I was able to detect a difference with the Spindle Mount installed. All the charts you see in the video are from the Vibration App and the axis are time and g-values. It was an interesting project but please take the charts with a grain of salt ... these are not professional vibration tool results and for all I know it is all backwards LOL.
