Hello all I just got done a butt kicking marathon getting my M Plus to drip feed. If you have aan M or T plus your trying to drip feed I will give you a cable/parameters combination that will work up to 9600 baud. You will be able to transfer mazatrol and G code programs back and forth, and be able to drip feed large G code programs. Should also work on M (T)32 copntrollers. But I dont have one to try it on.
