Hi to all the Fadal experts!
I have a new to me '91 4020. I've machined a few parts OK on it, but am stumped at times why it does the unexpected. I have run a Makino with a Fanuc 0m for years, so not a newbie.
The machine is configured for Format 2 in G90 (absolute mode)
The part in the vice has the upper far left hand corner set as X0Y0Z0. I set the XYZ in MDI using G92, with appropriate X or Y value accounting for edge finder diameter, and set Z with a block under the tool. I've also set X,Y,Z using SETX/SETY/SETZ, still the same behaviour.
In the offset table I offset all the tools +3" in Z to run high above the part.
The first tool is T10 (1/2 EM)
When running programs I run using slide hold for the 1st pass, when I ran it for the 1st time I could see the -Z distance to go was to great, so I stopped the program, jogged it in -X and -Y away from the part and vise, and started the program again. The result is the video.

The program starts by going up to the toolchange position, plunges down below the part before the spindle starts, then rapids up to where it starts it's 1st G1 move in +Y.
The program start is below. So what am I missing?? I've tried Format 1 and 2, I've tried both Fanuc and Fadal posts nothing makes a difference. The E1 values are X0,Y0,Z0. Is it picking up an offset from somewhere that I can cancel at the begining of the program? I don't understand why it plunges down before the spindle starts. I ran a Fadal in the mid 90's and can't remember any of these issues. There's probably plenty of other mistakes in the program.
Thanks in advance for any help you can provide!!
Is the 'whine' from the spindle common, it sounds like a VFD issue, it goes away at higher speeds
