Hello grasshoppers I need some help in calculate the angle (c axis) between to points (x,y) and (x",y"),and puting that result in the gcode tks

[angle of rotation] Hello This was my solution Thanks for the help

Hello I have a clay 3d printer, the nozzlle have rotation. I need to create in the gcode c factor to control the rotation I think is the angle between two vectors(x,y ) and (x",y")

You need to investigate the slicer that is recommended for your printer. I am not aware of any 3D printing slicer that has an option to rotate the nozzle. My guess is you are printing with a non-circular nozzle opening, and your printer has the ability to rotate that while printing. Try contacting t…

Hello Xavier The problem is that i need the rotation of the C axis ,and the slicer programs I know no one have it. The only software I know that works with C axis are cnc software, not 3d printers software Tks

Some CAM software allow other variables. But i dont know what C is or how your printer expect to see that in gcode (one operation or sequential ops). You could search-replace or write a script to reprocess the G code. The rest is just math and interpolating your position/angle.

a device manufacturer will usually put commands specific to their machine in what is called an “M” code, which can simply be a line in your gcode file. something like “M30 60p” ; mcodes are usually machine specific, although some are generic across machines. Manufacturer of your machine will know. …

tks This is similar to Tangential Knife Rotation , but in 3d

Do you mean two points? There is no angle between two points. You probably mean the angle between two lines (or vectors) from a third point to each of two points? Posting some geometry with a clear image usually helps to communicate your goal.
