hi, I am having a problem with fusion 360 using guffy’s post processor (for marlin) where the z axis moves up at the same speed as the xy feedrate, while the plunge feed rate is going down what I set it to. I am a new user so please forgive me for my copy pasted gcode.
using latest post processor and fusion 360 version.
bought all parts from v1 engineering website.
copy pasted only a small part of the gcode as the entire thing would be too big

;When using Fusion 360 for Personal Use, the feedrate of rapid moves is reduced to match the feedrate of cutting moves, which can increase machining time. Unrestricted rapid moves are available with a Fusion 360 Subscription.
