I have a problem of speed using replicape on corexy. Using branch master. I recently take time to confirm the issue with some users, different models of corexy/controllers.
For example, Kid buu (http://www.thingiverse.com/thing:1682656) with a 0.6mm nozzle and 0.225 layer the estimated time is 3h15, and the real print time is near 6h!
On a I3, same model, same speed , 0.4 nozzle 0.19 layer, estimated time 3h58, real print time 4h20.
With a more little model, Super Saiyan Marvin, to have a correct estimated print time I need to push speed to 140%
Pareil chez moi
