Hey Nicholas,
There is a reason that the CrossFire includes casters whereas the PRO includes stationary leveling feet; due to the CrossFire PRO machine’s weight, there is too much tension while moving the table when using casters directly inside of the leg tubes. The tension causes the inserts in the leg tubes to pop out, resulting in the PRO machine tilting over and dumping the entire contents of the water table. Additionally, the larger cutting surface of the CrossFire PRO is more difficult to level than the smaller original CrossFire. Because of these two factors, we found that the best user experience was to have the PRO machine be stationary.
If you must have the PRO be mobile, we recommend assembling it onto a rolling platform that can support the weight of the machine. Here’s an example of such a platform:
