Yeah, pull off is even easier than M666. Change the setting, test, save. No M666 in grbl, not needed just use the pulloff.

Agreed. My first experience with GRBL and using pull off was on a little diode laser set I got. It took only seconds to get at how it works, and only minutes to get it working like I wanted.

Just to follow up with the new config file. I ran the following test.

Still Low Memory warning, but not quite as low
Hmph… I’ve been running on Low Memory since the early aughts…

What about in polling mode?
Low memory warning goes away if I switch from Auto:1500 to Poll:3

I need to find a way to make that a setting in the preferences file then.
Thank you so much for trying that. I can’t seem to trigger a low memory without just logging in with a bunch of browsers.
Is the memory limitation the 520KB of RAM included on the ESP32?
Would it be possible in the future release of the board to include an external RAM chip on the board, or switch to one of the ESP32’s that already have it included?
Or does FluidNC have to be compiled in a certain way to be able to address that?
(I’m very new to ESP32 and looking into this type of hardware, so bear with me…)
I was reading here:How to use external RAM on ESP32?
And then searched and found these with an extra 4MB included. HiLetgo 2pcs ESP32-CAM Camera Module ESP32-S OV2640 2MP Camera Development Board + Micro USB to Serial Port CH340C 4.75V-5.25V Wireless WiFi Bluetooth with TF Card Slot for Arduino Raspberry Pi
No idea if this is even an equivalent thing to what’s in the Jackpot, but is that something that could help in the future? Or am I way off?
Think I got it, Testing again now before changing github configs.
No idea honestly.
As far as I know…seriously not much…this is just a matter of a lot of things happening at the same time. I am more wondering why that file triggers a low memory warning. I have not seen that yet and I loaded some giant small segment files from open sauce and didn;t see it.
It does not happen with the test crown for you right?
I’ll check it out in a little bit. This is the file if you want to peek at it.
YZ plate DXF v1.gcode (66.8 KB)
It does a 3mm drill in all of the linear mount holes with a v bit to mark the holes to drill later.
Then using the 1/8" endmill, 15mm/s, 1mm DOC, 45% stepover at 13.2mm total depth for the rest of the holes/parts.
I run a set of 12 yz plates nearly everyday, I am going to take another look at your file and mine.
I just hit run on your file (loaded on a microsd card), no memory error.
Poll or Auto?
Both I think Poll for sure.
I just updated the preferences to polling at 5 seconds, tested your file at 3 seconds polling.
No warning running the crown gcode from docs page

Reboot, run file.
No memory warnings.
Edit: Also found this in the FluidNC wiki

I know right?!
I just did a bunch of cuts and used pause a bunch…man is it nice to know it is going to pause and resume when you want. Liking this board more and more. I would have never paused the SKR I would have just went without the dust shoe.

I did figure out the pause job and resume finally the other day. it took a bit figuring things out from my phone since you get no tooltips and can’t see the whole interface at once.
It would be nice if there was a popup or something though with the MSG text during probing, etc for prompting
