I am still very wet behind the ears concerning CNC so I'm hoping this is just something simple I don't know about yet.
I recently purchased a converted Sieg Mini Mill from Syil America labeled by them as the X2. The motors they install are Nema 23 stepppers and they drive ball screws. I have set up the machine with the bundled software they provided, including Mach3 and BobCAD/CAM. When opening Mach3 there is a profile provided for the X2 which loads correctly all relevant settings. This made it very simple to get the machine up and running but I ran into something puzzling when I tried to run my first program.
When jogging the machine the motors appear to be tuned well and the steps per for all axes is 25400. I wrote a very simple pocket milling program using BobCAD to test with and when I run it the machine does not run smoothly. The end result is still accurate and well finished but the nice smooth motor motion present while jogging is gone. I was not sure what post processor to choose when writing the program so I just randomly selected the Haas post processor in BobCAD and ran with that.
The options in BobCAD for post processors are:
Haas VF Series
Is this where my error occurs? Is it a motor tuning issue? Is there even an error? Perhaps it is normal for the machine to take audible steps while machining? I apologize if this is a ridiculous question but I didn't find a solution in the training videos, manual, or previous forum posts. Perhaps I haven't looked closely enough. Thanks for reading.
