Works great...
FWIW my plain ol' MARS (s/n M20SILVER20200401, fw v 4.3.2) has supported .ctb files since I got it in May of this year--my previous M13... model (October 2019) did also.
The MARS 4.3.4 f/w supports the .ctb files too--the "Pro" is a plain ol' MARS with minor upgrades--if they really wanted to make a "Pro" version they'd need to put a better Z-axis mast on it
