Printed gears stick together

[raylo32]

I am trying to print a herringbone gear set I found on Thingiverse. It is a pair of matching gears... basically a small gear driving a larger gear for a reduction that I customized for size. I printed this out on my Qidi XOne (2) and it worked fine, the 2 gears mesh perfectly but came apart nicely as if they were 2 separate parts. Only issue is that I need to make these bigger than the Qidi can print so I sent the job to my Clik N Print which is a Makerbot clone. Again, it printed fine but the gears are welded together and will not come apart without breaking the ring gear. See pics below, blue is the Qidi gearset and red is the Clik N Print. I stopped the red print early to check for size and to see if the gears would separate... and they don't. Are there any settings I can change to get the Clik N Print to print this properly? Any other tips?
