When I cut wax models I can easily vacuum the chips as I cut for really long runs.

0.5.3.3 Expressions and Binary Operations
An expression is a set of characters starting with a left bracket [ and ending with a
balancing right bracket ]. In between the brackets are numbers, parameter values,
mathematical operations, and other expressions. An expression may be evaluated to
produce a number. The expressions on a line are evaluated when the line is read, before
anything on the line is executed. An example of an expression is:
[1+acos[0]-[#3**[4.0/2]]]
Binary operations appear only inside expressions. Nine binary operations are defined. There
are four basic mathematical operations: addition (+), subtraction (-), multiplication (*), and
division (/). There are three logical operations: non-exclusive or (OR), exclusive or (XOR),
and logical and (AND). The eighth operation is the modulus operation (MOD). The ninth
operation is the "power" operation (**) of raising the number on the left of the operation to
the power on the right.
The binary operations are divided into three groups. The first group is: power. The second
group is: multiplication, division, and modulus. The third group is: addition, subtraction,
logical non-exclusive or, logical exclusive or, and logical and. If operations are strung
together (for example in the expression [2.0/3*1.5-5.5/11.0]), operations in the
first group are to be performed before operations in the second group and operations in the
second group before operations in the third group. If an expression contains more than one
operation from the same group (such as the first / and * in the example), the operation on
the left is performed first. Thus, the example is equivalent to: [((2.0/3)*1.5)-
(5.5/11.0)] which simplifies to [1.0-0.5] which is 0.5.
The logical operations and modulus are to be performed on any real numbers, not just on
integers. The number zero is equivalent to logical false, and any non-zero number is
equivalent to logical true.
