General Mach Discussion / Re: Need help setting up tools for first time

Something you have to remember there always has to be a master of some sort that references Z0.000 TOP of material.
As a simple method and you have to repeat this exactly each time you setup tools.
Take the longest tool you have in the set to use as the master. Set its offsets to ZERO. Touch off the Master however you want and set Mach3 to Zzero. NOW touchoff each of the other tools and record the offsets from the master. and record in the tool table.
NOW when you start the program run you MUST touch off on the part with the master tool and set the Z to ZERO. NOW all the tools are synced to the correct offsets based on the master.
NOW you must remember that in order for the TOOL height comp to work you must invoke the G43xx xx Call. You can do it in the M6 macro or from Gcode in the program BUT it must be done in order for Tool height comp to work. You also must remember to remove the Comp with G49 afterwards.
AFTER you see how it all works it will be easy peezy from then on.
I suggest testing with a styrofoam block. To SLOW down the machine motion use the FRO and RRO to slow it down to a crawl. This will give you TIME to see what is about to happen. You can also single step thought the code and watch EACH line function. You can also use the distance to go DROs to see IF it is going to STOP where it should for each line call.
NOW there are as many ways to do this as there are hairs on your head. Starting out pick ONE method and get it perfected in your head. Then the process will become second nature.
Just a thought, (;-) TP
