Are the blue lines (tool paths) in gSender the center of the tool or the edge of the cut? I’m having some issues calibrating my machine and can’t seem to find the answer to this question. I’m also having a challenge with my CAM software, so that’s not helping me.
Thanks in advance!
My guess is the centre because when setting the tool position before starting a job the centre of the cutter is used as the starting position.
Thanks, fasttiger. I don’t know who checked it as “solved” or why - it’s by definition not solved when the only reply is quite literally a guess.
I’d love a definitive answer from someone who knows for a fact before I spend another day figuring this out. I really didn’t think this would be such a mystery. But again, I appreciate your input, fasttiger.
@AlexLTDLX I jumped the “solved gun”. Sorry about that.
I have no idea how the answer to this will affect the calibration of your machine, so I regret that I can be of no help.
No worries. I’m working it out now with some tests (still using Chat GPT to generate NC files, BTW). I’ll post here if I figure it out and update the other post when I figure that out too. I’m now a bit under the gun on this project - I’ve got another youtuber with a much bigger channel than mine who wants a couple of these things for a project he’s doing…
@AlexLTDLX When you get it all worked out, I’ll be interested to read what the blue lines in gSender have to do with the calibration of your machine - according to ChatGPT. I can only suggest that, since it’s already given you incorrect information about gSender, you may want to proceed cautiously. Carefully, review the gcode it creates before running it.
TLDR: The blue lines in gSender are the center of the tool. fasttiger was right.
After much swearing at ChatGPT, it took one of my employees to point out the coordinates in gSender tell me the extents of a project file. I’ve been trying to dial in the exact (well, as exact as is reasonable) steps per mm for my machine, and I needed a 80mm x 150mm rectangle to do it. I know it sounds easy, but since I’m using ChatGPT to fix the Kiri:Moto generated nc file, I wanted to make sure everything was working on the same page.
Of course, none of this guarantees the steppers in my old chinese 3040 are accurate and repeatable, but the 80x150mm test cut repeated within about 0.06mm. Good enough for this project and this machine. I’ll now go back to the other thread…
@AlexLTDLX I’ve checked @fasttiger post as the solution as we now know that it was. I realize that you have other issues in other posts, but at least this one is resolved.
I’ll close this topic.
