Change max retraction speed in community firmeare

compman2

I was trying to get my cura to give accurate print times based on a linked article in the forum.  I was looking up settings in the config.h file for DEFAULT_MAX_FEEDRATE and it appears that the extruder is set to a max speed of 25mm per second.  I have seen recommendations for retraction speed for the A5 at 50mm per second.  Is there a down side to setting this rate higher in the firmware to give more options?

I had it set at 25mm/s to avoid skipping steps - there's no other downside. If higher works ok for you without skipping, definitely give it a go and see if it improves your retraction results! I'd be interested to hear how you go!
