Like others I have wanted to add a pen drawing device to my crossfire pro for some time. Initially I wanted to mark bend lines for the brake and draw nonstandard brackets to check bolt hole and other alignments needs prior to cutting them in steel.
I have seen others, but I didn’t like that some of them require you to take out the torch to draw then reinstall the touch etc. So wanting to keep it in place while cutting require it had to be made out of something non-burnable or meltable.
I also wanted it to be a little less idiot-proof (for me) so I wanted to make sure setting it up generally was as straightforward as possible.
I drilled and tapped two m5 bolts into the machine torch holders. Cut the long piece out of 1/8th and the pen holder out of 16 ga. The pen holder is modeled as sheet metal in fusion so bent it up and welded the two together.
This is great and like that you created the offset which would be the issue with doing this type of design. I’ll have to check this out over the holiday weekend. The design that I’ve been using is from @davebogdanski and really works good. He really thought of everything down to the correct spring in his design. I could even see using his sharpie setup in your bracket design. Best of both worlds.
Lastly in fusion, when you want to “draw something” you select the custom sharpie pen post processor. Again that shuts off the touch, the THC, and - temporarily - creates the offsets to position it properly. After use the offsets go back to normal zeros for cutting.
I’ll have to do a video on creating hatch lines because it’s a little tricky the first time you do it. I did it few months ago and found myself looking back at previous design scratching my head wondering how I did it for few minutes. If someone else wants to do a video please feel free to share. With all the recent sharpie talk I know it’s something others might like to tryout.
Here is one I did a couple of weeks ago works great.I used the axidraw extension for inkscape. Used the plate marker setup in sheetcam. I posted it on fireshare if anyone what’s to down load it. It took about 45 mins to draw it.
I’ll have to check out the gcode later. I played around with my easyscriber about 6 months ago on painted steel, but it was chipping so I lost interest in messing with it. I mainly used it for bend lines but now I just use my marker setup.
Recently we had a discussion on this forum and similar holder. He created the offset in the gcode which is the real issue with this type of pen holder. very cool to build that into the gcode. I like the one i have but you do have to remove the torch but no offset to deal with it. not sure if you care about the offset but if you plan on using for bend lines and things that also use your torch in combination you’ll want to figure it out. Once you know the offset you could zero torch in firecontrol and just move the pen to your offset and hit start. that would be the easiest way to accomplish it.
I think we’re talking about two different things. If you want to use your easyscriber and torch on the same design my post above might make sense. You can’t zero your pen and zero your pen at the same origin without understanding your offset. It’s very cool you’re doing the scribing. I look forward to seeing other designs.
