Oh yes I see how you calculate it for this example on simulation. Actually I would need to make and calculate it for general case where fillet can be only quarter of length or any other arbitrary length. I get line segments from 3d cad program. Need to think if calculation of g93 feed is possible

Thank you Andy - interesting video I looked all of it - but I couldn't find out where I made mistake - I mean - I understand what guy is saying in video, and I think that formula I wrote still holds - g93feed = g1Speed / length_of_segment - or I am mistaken? however I cannot find place for arc

Thank you Chris and Andy, I read about G93, and rewrite my gcode program, in a way, that I assume I want to have G1 speed 700mm/min. So for each segment I have I calculate F value for G93 with formula: g93feed = g1Speed / length_of_segment I rerun program in simulation this time using halscope
