Internal machining. Error messages.
Posted: Fri 13 Jun , 2025 15:19 pm
I've been experimenting with internal machining on a Mirac and have produced the attached .LCM file.
When I try to generate Gcode I get the errors below which I do not understand.
(Drilling)
Cannot Process: Drill:8 diam:6.00 is less than current internal diam:11.11
Cannot Process: Drill:4 diam:10.00 is less than current internal diam:11.11
(Internal Roughing)
Cannot Process: Current internal diam:11.11 is less than min. tool diam:12.00
There is no internal diameter of 11.11mm and I don't see how it matters in any case when drilling.
I can understand the Internal Roughing problem as the boring tool is specified as 12mm and in order to start boring it would need to make a cut of 1mm in order to enter a 10mm drilled hole and that's with zero clearance on the back edge of the tool. There's still a reference to an internal diameter of 11.11mm though.
Would appreciate any advice. Thanks, Max.
