Thanks Matt appreciate your support and agree on the pseudo steps. No need for you to switch back to klipper yet, I’ll take a stab first. I’m switching back and forth between klipper setup and designing 3D parts for drag chains. I’ve got some prototypes printing so I’ll try working on the resume code before work this morning.
Update: I’m close, I see how it works and am able to store the position at the point the process is paused. I just need to get the syntax right for retrieving them in the resume macro when saved in the pause macro.
I see how other functions do it and so expect to crack it tonight when I take another look.
Wasn’t too difficult and not finished yet as I want to put in some more safety coverage and not stopping the starting the spindle, but I do have it returning to X,Y before Z. I’ll paste the code here for anyone looking, and I’ll repost a more complete version later.

Wow. I’m not that into coding. I just tried this on my Voron Trident and it didn’t function as I expected, but like I said, I’m not that into coding to fully understand what it is supposed to do. It is funny that I was about to start playing around with figuring this out and you posted. I’m trying something a bit more simpler. It might not have a lot of safety built in like you are planning but it is simpler and I can follow along and understand it .
I just might have to reconnect my Pi (I only have a zero that will not work for cutting, but it worked for moving around) and re-test your macros. It wont be an issue since I still have the image on a SD card that I can re-insert into the Pi and I’m back to where I left it when I switched to Marlin.
EDITED: Well, I’m now running into whenever I PAUSE it moves the router/spindle to the MAX X,Y when it would be more helpful to move to the MIN X,Y (0,0) to be able to change the bit. Trying to figure out how to change the PARK location for the PAUSE.
3rd EDIT: I found my mistake - I had the PAUSE macro defined multiple times (I never looked into the mailsail.cfg file where it was original defined). Neil, your RESUME works nicely.
Hello,
Very nice project
I’m also on klipper on an octopus BTT for my MPCNC Primo.
For the resumption of the break, it’s quite complicated, what I do is that I make a gcode for each change of tools.
You have a risk of moving your motors by changing the tool.
Sorry my English is very bad, I am French speaking.
Cool!
I didn’t give instructions as I’ll do that once I have it working the way I want. I just shared the code in it’s current basic state as I’d solved the initial problem and so folks following along can benefit.
Here’s the latest version of the mainsail config I have for klipper which allow me to use Pause and Resume. NOTE: This should be used with caution, it is not complete AND not yet been tested on a CNC with an actual spindle connected
I haven’t yet worked out how to persist the speed the spindle was running at before pausing, so it’s hardcoded to resume at 5000.
I didn’t get much time to work on it yesterday and won’t tomorrow so wanted to share where I’m at.
This is my current complete mainsail.cfg

I’ll be focusing on the drag chains and other modifications next, and still some time away from being ready for cutting. i.e. I need to build a table, speed control for the Makita etc.
Here’s the drag chain mount I’ve been working on, doesn’t require any screws or modifications to existing parts, just slides into the end of my Stainless Steel 1" tubes. Please excuse the quality of the print, I made some tweaks and haven’t spent the time to retune

@N7NJO I do like those stainless steel tubes. Could you provide the link of the exact ones you purchased from Metal Supermarkets? They have so many options. Thank you
I’m trying to follow along with all of this.
I put the cb1 on the manta and got it on my Wi-Fi. I can’t get the “make flash “ to work but Klipper will at least start. It always shows errors.
Because I don’t know what I’m doing I’m being really conservative. I haven’t connected the motors and when I do I’ll have the belts off.
So I keep starting Klipper and chasing errors. Each time it starts I see an error. I know I fixed it when I get the next error.
I put the hardware cfg files in a directory and the macros too. ( including Neil’s macros. ). Also I fixed a few duplicate pin used errors. The one that I am stuck on is “file has no header”
Maybe I started wrong. I used the generic klipper for the m8p board. Or is there another one that I should use?
Thank you for any clues.
Mark
Actually I followed the recommendations from many others and didn’t order online. I went in the store and asked to look what they had, for stainless tube with 1" outer diameter. I believe they called it “decorative”… and there wasn’t anything else to choose but it was just what I was looking for.
Beware, wasn’t cheap.
I started with the generic klipper file for the m8p, then tweaked it to work with my set up. The contents of the files you see above are the result of my taking that modified generic and splitting it into separate files.
So when Klipper starts it looks for the printer.cfg, you can see mine then includes all the specific files. I no longer reference the generic mp8 file.
As for the “make flash” did you follow the steps on page 36 of the Manta manual?
Can you share more of the error you get for “file has no header”
I’ve made more progress on the design of the drag chains mounts, although I’ve been slowed by having to troubleshoot some printer issues. I wanted a solution which kept the chains of the main surface, while not replacing any of the parts Ryan designed. So I’m taking most of the support from the tubes, while only resting on the CNC parts. I still have more to do, but once I have the cabling clear I’ll start working more with Klipper and plan to upload the parts if others want to use.
Unrelated: I just figured out today that if you sear the edges of the mesh thingy (where you put the cables in) they can’t unravel. I can’t see whether you did that.
I had a similar experience. I called Metal supermarkets and asked for stainless 1 inch OD. 304 SS with a 0.65 wall. This is the common “plumbing” for Food and Pharma factories. (Plentiful in NJ).
I just read my cut list on the phone, and picked it up the next day. ~$105 for a 18 x 24 build area.
Only partially. I used MobaXterm instead of Putty because they had a portable version that ran without an install.
I did the first part 6.2 Compile firmware “make menuconfig. I adjusted the menu choices to match the image.
The “make” command worked and I copied klipper.bin, renamed and put firmware.bin in the/biqu. It won’t let me put it in the root of the SD card.
More to come, I should be typing this on laptop not iPad so I can copy and paste.
