Hi,

I'm trying out the passive probe I just got from Tormach, but having been pulling hair on the tool diameter offset.

I followed the manual to set up the passive probe in config fire, did the calibre, and stored it as tool 99 in my tool table, with 3mm as the tool as diameter.

but when I run the x+ and y- to locate the part's upper left corner. it did not compensate for the tool diameter when setting 0,0. I was trying to face mill 1mm from the side wall of a alum slab along the y axis and my tool totally missed it by a hair then I realized the origin is off by 1.5mm in both x and y to the northwest.

i restarted mach3 and it worked fine if i didn't select tool 99 and no preset diameter. but as soon as i load the program and tool 99 it'll not offset the 3mm tool diameter.

i'm totally confused. i've called tormach 3 times and got all kinds of answers, they were all very nice but i don't think they were on the point. one support told me to reload the controller image DVD which I don't have (i bought it used). can someone help? i'm using meshcam. below is my gcode.

thanks in advance. all units in mm
