Recover a CNC Project in the Middle of a Cutting Process

I needed to stop my CNC router in the middle of a cutting process because I forgot to add some machining operations. I figured this would be a good video to show how I stop the machine and pick up where I left off. The process was made more complicated because the machine changed its location. Fortunately, I stopped the machine at a point I could use as a reference.
The pen-based monitor that I use. I highly recommend this monitor. It keeps my fingers from pressing the wrong buttons:
amzn.to/3aGqO6s
I use the Kamvas 16, but any of the Huion monitors will work well with the Mach3 screens.
My favorite tools:
Wera micro screwdrivers: amzn.to/3qEhynB
WorkPro Ratcheting Screwdriver (You see me using this in many of my newer videos): amzn.to/3qEQYLg
Knipex Cobra Water Pump Pliers (these are so versatile): amzn.to/34fIwur
Knipex Wrench Pliers (The most elegant tool I have seen and use constantly): amzn.to/3HyzNlv

Let me know if you know of another way to do this. Leave a comment. Thanks.

[@PatrickHoodDaniel]

This is only one of m any ways to recover from a stopped CNC process. I hope this helps anyone that needs to stop their CNC router and make modifications to their design.

Wouldn't it be easier to center on a known hole and then enter that location in your position readouts?

[@PatrickHoodDaniel]

That would definitely be another way to do it. Getting it centered on a hole is difficult, at least for me. If I know I need to stop the machine, I will wait for the machine to go to a hole that is a cammed operation (no spiraling) and press the feed hold button. That way, the machine did the positioning for me.

I agree, or send the spindle back to 0,0 and enter a coordinate near to where you had the problem and run from there and additionally as a test raise the z home to not touch the surface just to check positioning, then just rerun the first step again.

[@PatrickHoodDaniel]

@@chuckmoney1688 I forgot to mention. The starting location, where I set the origin, wasn't the home position. The position for this project was loosely based on a section of the machine where I had some contiguous material to use.

Any thoughts on the project I sent you?

if you had homing switches you would of not had to do this

[@PatrickHoodDaniel]

I have homing switches, and I do use them. Sometimes I want to make my origin at another place without the complexity of messing with absolute and relative coordinates. In most cases, I need to get these jobs done quickly, create an origin (because I never think I'm going to mess up), and just go. Also, I have noticed that homing switches (mechanical) are not too accurate, and this technique will be perfect since the machine did not move from that spot.
