CoreXY x2 #120

Closed oilytin closed 4 years ago

oilytin commented 4 years ago

would it be possible to add coreXY kinematics on two sets of axis XY and UZ? I've built a 4 axis hotwire before realising the limitations of the firmware. I have started looking at the code and fumbling my way through it. would you be able to give me your opinion(and any advice). Thanks

Hi @oilytin

To respond to the question: It would be necessary to give a little more information on your machine... An image or a diagram would be interesting to understand.

The axes defined in your need (X, Y) & (U, Z) seem strange to me...
According to the usual standard definitions of the axes (cf. http://linuxcnc.org/docs/html/gcode/machining-center.html#_axes), U must be parallel to X and Z perpendicular to X and Y ... Ne shouldn't they rather be defined as (X, Y) & (U, V) Should the movements of the 2 CoreXY systems be synchronized (mirror) or independent? In the first case, you will have to add code in the axis mirroring mechanism, in the second, you will have to duplicate all the CoreXY code to the new chosen axes.

A pull request is absolutely not the right place to ask a question or request a new feature. This question should have been asked in an issue. So, I close this request, please open a new issue to deal with your need.

Thank you for your reply Gauthier, I have posted the information as an issue. Regards Anthony
