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 mayb…

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 gc…

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 th…

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.

It is supported, the sm can parse it, but it just doesn’t work well: Snapmaker/Snapmaker2-Controller/blob/b6162fd040a2aee155143978a908c39a6f9d16d3/Marlin/Configuration_adv.h#L1094 #define G29_RECOVER_COMMANDS "M117 Probe failed. Rewiping.\nG28\nG12 P0 S12 T0" …

@nivekmai I wonder why that is.

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 …

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…

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.

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

@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.
