Is there a difference between a parallel cable and a serial cable. I always thought the serial crossed over 2 and 3 pins and parallel kept them in line?

Also, should I use a parallel cable from Lpt1 to Breakout board?

Hi, Beezerlm

Yes, Most BOB use a 25 pin connector, So you need a 25pin M to 25pin F cable (normally called a Printer extender cable), Serial cables rarely use all 25 pins.

All though some BOB use a standard printer cable.

Yes, Most computers Lpt1 is the only one unless some one has added more Lpt's.

Hope this Helps, Chip

Is there a way to transfer tool & work offsets from one profile to another in mach3 ? If so, how ?

Hi, Beezerlm

Mach can retain the tool & work offsets, In your G-code you can call them, If your meaning of profile is G-code.

If your meaning of profile is Mach startup profile, Not sure if the Tools/Fixtures Data-files can be placed in a different  profile.

Hope this Helps, Chip
