I've noticed that the chameleon is slightly slow to adjust the cam. The extruder motor feels faster than it was. I've noticed that with my Mk3 settings the filament is extratced more on unloads.
But for homing or anything that involves the CAM motor, the device takes half a second to register the commands. I dont think I have the courage to flash it back to MK3 to do a comparison. Is this normal or am I imagining things?
That's normal... you'll need to adjust for the delay for 3DClippy to be activated. Even if you don't have it, it's running it. I'm working on an update to allow you to skip that so it will restore it back to close to the Mk3 timings... but if you have the 3DClippy installed, it needs to run before it backs out filament, so you need to add that time to your G4 delay code to compensate for it.
