That says go, at the same time, to X0 Y0 and Z0. Z0 is all the way down, you don’t want that. You want Z up so usually +10 from where you currently are when you finish a job.
Park is Z all teh way down so when we power off it doesn;t drop.
Exactly M98 is subprogram call and M99 is subprogram end
So you can make one program that calls another program. But I have never tested does this work in Marlin.
If you change M00 to end, steppers stay energised and gantry will not fall?
Thanks that’s what I needed to know I just started learning gcode the past month or 2 , I didn’t realize there were commands such as END, and I will look more into M98, which sounds like what I would want also. This way some repeated work won’t have to be done each time.
Feel free to try. I havent try it with Marlin. But I don’t see reason for that. For example. If you want to move the router away from your workpiece at the end of program. As many have said You can modify the basic end of program like G00 Z+10. Y+900(means raise z10mm move y900mm). Before M30 or M02 (or M00). Or you can modify it like you need. And you can save these information into estlcam so everytime you post new program tje same end you have made appear into g-code file.

Marlin does not have M98 or M99. But it does have M32 to launch another gcode file as a subprogram.

Apologies if this is off in the weeds from your original question, but https://youtu.be/fGtbkVJBXyE?si=_nYAI3zjYi8zyxOO showed me that I could just choose a parking position and save it permanently under G28 or G30, then I just wrote a quick macro to move to 0 0 0 in those workspaces. (Not sure if your controller supports that, I use the glorious v1e Jackpot board.)
Edit : if you’re using Marlin, G28 and G30 do totally different things, so never mind in that case!!

Old thread but I thought I would reach out to the author. Trying to plan a CNC for machine for foil board milling. My stock is 8" thick so need to recreate what you have done and hopefully no repeat your mistakes. I decided to modify the Lowrider V4 as I want to be able to mill a 8’x2’x8" stock.
Besides taller XZ plates and longer lead screws (plus the dust extraction bristle) what else did you have to modify? What lessons did you learn along the way?
Again, Eli, please stick to one thread. Modifying the 4’s plates is not really possible.
This Author has built a similar cnc machine for the same purpose. I don’t understand why to start a new thread for every question I have.
You have just one question: how to make it taller and you are asking it in every thread. Open up a build thread, ask your questions in it and you are good. You will also later find the information you asked for again… 
Also, he did it with the LR3, you want to do it with the LR4 which is completely different since the side plates are fully printed.

I 100% agree, this thread is not the right place. New threads are free and drastically help us, help you.
