After scaling by 10.0:

The code involved is:

def __init__(self):
    ...
    self.zeros = "T"
    ...

def parse_number(self, number_str):

    if self.zeros == "L":
        match = self.leadingzeros_re.search(number_str)
        return float(number_str)/(10**(len(match.group(2))-2+len(match.group(1))))
    else:  # Trailing
        return float(number_str)/10000

The numbers are being divided by 10000. If “L” had been specified, the following regex would have applied:

# Parse coordinates
self.leadingzeros_re = re.compile(r'^(0*)(\d*)')

Then the number 02664 would have been divided by 10**(4-2+1) = 10**3 = 1000, which is what is desired.

Leading zeros weren’t specified, but www.excellon.com says:

The CNC-7 uses leading zeros unless you specify otherwise through a part program or the console.

Note

The parser has been modified to default to leading zeros.
