I have not been able to find in cura how to set speed of an additional fan. ex: M106 P2 S150 Currently I have a find and replace script just to turn on my aux fan at a certain layer. What I would like to do is to use "insert at layer change" to reference the part fan speed at the start of each layer. ex: when to insert : before G-code to insert : M106 P2 S{cool_fan_speed} but when the file is processed the g-code shows as M106 P2 S{cool_fan_speed} not M106 P2 Sxxx am I missing something or can this not be done?

Well...... I'm an idiot...... So the 60% I was seeing in the g-code was actually the requested speed (500 mm/s) x 60 (seconds) = 30000 mm/m.

@GregValiant I have minimum layer time set to 0 as this was an issue not long ago when printing in vase mode. I had to disable print recovery and set minimum layer time to 0 to get vase mode to work correctly. Minimum layer time is still set to 0. I can't think of anything that would affect the entered print speed vs g-code print speed. No matter what speed I set its always exactly reduced by 40% (or 60% of set speed). If I enter 500 mm/s I get 300. If I enter 100 I get 60. If I enter 224 I get 134.4 The only time it deviates from the 60% is if the set speed is really low. Sub 50 mm/s. Is this a bug or is there something else that's reducing the speed? Also. Downloaded "Printer Settings" last night. I will play around with that and report back.

Dialing in speed settings for my printer and noticed that the speed shown in the g code file is only giving me 60% of the requested print speed. So if the speed settings are set to 200 mm/s. I slice and save the file. Open the g code file and the speeds will only be 120mm/s. Anyone have any ideas? Also how do I change the Z axis speed? It's at 3mm/s at the moment.
