MRRF 2018, Ideas?

For completeness sake, I changed the arc resolution setting to 0.1mm as you suggested and reran the logo gcode file. Definitely seems inproved. I also had to update the firmware as I had no clue what was flashed previously… had to remap D9 to pin 44 for laser control, and set in steps/mm for X/Y, etc.

Wow huge improvement. I guess I need to make the change then. Looking into some different wiring harnesses as well. So many things…

Finally, and not surprisingly, slowing down improves things greatly. Feed of 600 mm/min and half-power (128… to avoid cardboard fire) gives

That’s cool. The ‘I’ definitely looks like my grandpa’s handwriting though. Is that the cardboard surface?

I thought it looked more like my hand-writing… 71 years will do that to you. Not sure really… the "I"s in “ENGINEERING” are slightly different and all the linework is [to me] alarmingly “shakey” in close like that. That is some heavy cardboard from a mattress box… but it seems smooth enough to not be the culprit. But maybe…

Maybe try your laser burning on some Masonite? That stuff is very smooth.

The Lulzbot touch screen experiment panel finally arrived.

I just looked through the files to get this working…yikes. I think I will need to shelf it for a bit. There is a lot to digest in there. I think I can get it working but it might be one hell of a rabbit hole once I get started if it doesn’t work right away.

Is there an image file this came from? I have something in mind I want to do…

I swear I have the files for the 2019 MRRF linked somewhere, DXF and Gcode.

Yeah I saw the DXF. Was wondering if it was based off of a SVG or some file with colors or shading.

No, I pulled the DXF from solidworks ISO view. I am not sure what type of file I can get with color other than the renders I have up already.

Is the 2019 one any different? I am going to make this and frame it at some point…

Hmmm, not sure it does say MRRF2019 on it though. So if it is going on a wall maybe the 2018 is the better one.

I don’t see a dxf. I downloaded the zip file in the post i quoted and it’s a .e10 file. What in the world is that?


oh, it’s estlcam.

I do not see a way to export it. Here are the two dxf’s I used. (647 KB)

Kinda funny I have permission to upload any file type…even I get spam filtered.

lol, I was like… there ain’t no file attached!



It’s for our protection, really. :slight_smile:

I’ll trust my shop with his machine shoving a spindle running at 20,000 RPM from tearing it up, but I don’t trust my laptop with a zip file from his website :slight_smile: :slight_smile: :slight_smile:

Trust has got to be earned, man… :wink:
