Is it possible to use G92 multiple times in code?
For example move LowRider to certain area, use G92 X0 Y0 Z5, do the work, move it to different area and again use G92 X0 Y0 Z5 and do the work using exact same code like previously.
I would try it myself on LowRider but I am not close to it but want to prepare code. That is why I ask the question.
Thank you
It is possible to do, but I would not advise it.
For one, Gcode does not have looping structures, so running the same code repeatedly doesn’t work. (CAVEAT: RepRap Firmware supports Gcode loops, but GRBL and Marlin do not.)
So you would basically be running the same file multiple times. Since you really should be monitoring the machine while it is running, there is little time to gain by letting the machine run in loops. You have the possibility of running the job too many times, and running off of your work material or into a physical limitation of the machine, (and there is one easy way to start a fire right there) or mess up way more material than necessary.
It might be worthwhile for very small jobs, I suppose, with a very proscribed and limited set of loops.
Anyway, yes. It will work, but without a looping structure, it probably isn’t really worth it. (With RepRap firmware, BTW, I do not use G92 at all, as there is a more direct way to manage that.)
Thank you for your answer. It is for different purpose than LowRider is usually used, so I don’t worry about fire or anything like that. I would categorize it as small job and it is for very limited set of loops.
I will try multiple use of G92 when I have access to LowRider. So far I tried gcode simulation program and it was not working with that command, so that is why I was asking the question.
It will work fine, the program you used does not understand G92, as the conventional way to do what you are asking is change “Workspaces”, G54+. Coordinates - V1 Engineering Documentation
As an alternate solution, you may want to take a look at the features in your CAM. In Fusion 360, I can create various patterns of toolpaths.
Thanks for Your answer, I didn’t know about G54+ before.
What do You usually use differemt patterns of toolpaths for?
I’ve never used Fusion 360 patterns feature. When I first found this functionality, I thought it was cool, but I’ve never found a personal use case for it. I mostly make individual gifts with my CNC and therefore don’t need repeats of the same tool path. I imagine if I was manufacturing some items for sale, I’d find them very useful.
I tried to post the flyout menus for this feature when I mentioned it in my last post, but my image clipping utility couldn’t grab them. So, going lower tech, here are phone images of the flyouts:
Very interesting, thanks for sharing. I had no idea about these options
