CNC Gcode Estlcam

Sal1 · October 11, 2021, 1:39pm

Hello,

I’m trying to generate gcode for the CNC function in Snapmaker 2, through Estlcam, but it seems that something’s wrong because Snapmaker doesn’t start the job, instead it gives me the messages “FabScreen has stopped”. Also I notice that coordinates are set “infinity x infinity”. I think maybe it has to do with gcode type differences between Estlcam and Snapmaker. How can I correct the gcode? Below you can see the code I’m using.

Thanks

M05

Most likely, the cause is leading zeros in the gcode commands. The Snapmaker expects G0, G1, M3, M5, etc. rather than G00, G01, M03, M05.

In addition, G3 is an iffy command for the Snapmaker (some people have gotten G2 or G3 to work, but they don’t always behave as expected). Also, none of the gcode samples I have on-hand have negative values for any parameter but Z, although this may be due to different origin positions.

brent113 · October 11, 2021, 4:11pm

Leading zeroes are handled in the gcode parser, that is valid gcode.

A quirk is power (not RPM) is 0-100%, so setting it to 12000 is capped at 100, but that doesn’t affect anything here

I have used G2/G3 manually successfully, never tried it in a program though.

I don’t see anything wrong with that gcode. Can you play it via Luban over USB directly to the controller?

And finally, when posting blocks of code wrap them like so with ticks so a scrollbar is added and the post isn’t 8 pages long:
```

I think G3 suffers in SM firmware for smaller arcs, idk if .5 is small enough to cause a problem, but I know some code I tried to run though arc welder had issues.

Artezio · October 12, 2021, 12:23pm

@nivekmai i remember something being said about G2/3 not being supported, they were supposed to add the support but I’m not sure if it happened or not, Edwin left Snapmaker shortly after I think.

nivekmai · October 12, 2021, 12:41pm

It is supported, the sm can parse it, but it just doesn’t work well:

@nivekmai I wonder why that is.

nivekmai · October 12, 2021, 1:44pm

No idea, I can barely read c and I suck at math, it seems to be something with the machine being flooded with too many commands, I’m guessing there’s some exponential algorithm somewhere, but I’m not seeing it. I do notice that the marlin source code has been updated quite a few times since SM last pulled in changes (many of the recent updates are intended to allow smaller arcs).

Sal1 · October 15, 2021, 6:01pm

Thanks for your replies. Turns out I was making a novice mistake: I wasn’t selecting the right gcode format for SM (Marlin) and I was expecting that “rub boundaries” would work, so I didn’t try to start the job without running boundaries… When I press run boundaries, it crashes. But if I go directly to start job, it works perfectly. I loke Estlcam a lot, very simple and novice-friendly.

Sal1 · October 15, 2021, 6:04pm

Another thing: in Luban’s working area, the arc commands don’t work, they appear as straight lines. But when it runs in the machine, they work perfectly also. Luban doesn’t read the file as well as the machine, apparently.

anjoku · October 30, 2023, 4:38pm

Hello, can you tell me how to create a file for snapmaker using estlcam?

Did I understand correctly that just “determine the limits” doesn’t work

Greetings
Andre
