How to change axis velocity during Gcode operation

Question

Good work everyone,

I have been working on a 3 axis CNC machine for a while. A lot of things are going great! But I couldn't find how to increase or decrease the axis speeds while processing the g code. I am using the SMC_INTERPOLTAOR block to manipulate the G code. I think I can overcome this problem with the 'dwtime' value in the entry of this block, but this does not offer a healthy solution.

I need support for this! I need to do an instant increase or decrease of the axis speed during a motion!

Thanks. / ByCNC

What is motion axis speed control problem method

Answer 1

While I have no experience with SoftMotion CNC libraries, looking through the documentation the dOverride input argument seems to be promissing:

... The scheduled velocity of the particular objects will get scaled by dOverride; thus the scheduled velocity can be increased resp. reduced in online mode...
