Oops, forgot to reply here. I sent the project file over a couple of days ago. Please let me know if it didn't come through. Thanks!

Not sure if this is a bug or expected behavior but where sharp corners meet, I get cut paths during roughing that remove too much material:

It seems like it makes a decision to place the cut path based on average height within the tool's diameter rather than max height. If so, perhaps that could be configurable? So far I've been able to work around it by adjusting stepover and other things but thought I'd mention it.

Thanks!

Hi Charlie,

I'm just realizing that I can actually set jog/rapid speed via gcode and override whatever might be in the firmware. Is there some way to specify that the "rapid speed" from the settings gets exported? It looks like the way Snapmaker's Luban does it is just by including a "G0 Z80.00 F[speed]" at the top, though I'm not sure if Z80.00 is relevant.

Thanks again!

Hi Charlie,

Wow. Looks good! Yeah I think that would help a lot. It would save a lot of trouble compared to fiddling with PBR textures when you can just adjust some parameters until it looks right. Nice work!

To answer your earlier question, I've been mostly interested in hardwoods lately: cherry, walnut, bamboo, oak, and the like. I'm still very new at this though so I'm not sure what defaults would be more generally useful.

Just for fun, here is a draft of a relief I'm working on in Blender for my video game-loving siblings and myself. The plan is to put it on a display-only side of a cutting board.

Is there a way to simulate material texture like wood or bamboo? I didn't see one but was hoping for at least normal maps, or maybe something fancy, like displacement maps and tessellated geometry to simulate how well details of your relief would show against a particular grain.

Hey, a quick update with a couple more settings I changed. It looks like FeedMax ought to be 1000 mm/min for the 50 watt module that comes with it, and 3000 mm/min for the upcoming 200 watt module upgrade (I think they're shipping now but I don't have one yet). The top spindle speed is 12000 for the 50 watt, 18000 for the 200.

Anyway, PixelCNC's Easel-based output continues to work well with the Snapmaker with the above settings changes. I'm doing a 6" diameter relief right now about 1/6" deep that seems to be going well. It has both a roughing and a finishing pass with a 0.25mm radius tapered bit. At 50 watts, its not exactly fast, but its relatively quiet and its getting it done. :-)

Thanks again!

Hello! Got a chance to try this today. It looks like Easel gets the closest. Unfortunately, while it drew out the right overall motions in the air, it never turned the spindle on. So, I made a copy of the Easel post, renamed it for Snapmaker, and set the UseSpindle field to 1 and the FileExtension to ".cnc" (so Snapmaker will show it on the thumbdrive). After that, I was able to cut a test project successfully (just some text 0.5mm deep). I'll try to do a more involved project from here and update with any more tweaks I discover I need.

Eventually, it would be nice to add a PixelCNC profile here:

GitHub - Snapmaker/snapmaker_cnc_post_process

because I think this program is what a lot of artists / casual CNC users are looking for.

Also, minor thing: it would be nice if the app warned that paths need to be recomputed after things like changing the work origin. 

Anyway, thanks for your help!

Tips and tricks welcome, starting with which file format works best for export. Thanks in advance!
