tool table
« on: April 03, 2020, 04:23:06 PM »
where can i find help in setting up a tool table in mach 4? i am new to mach 4; in the past i used linux cnc where there was a sample tool table that could be modified to the desired settings.
what i have found in mach 4 going to "view"-> "tool table", is a table named "tool offsets". that's as far as i get.

i looked at the video, that is for offsets. i am still at the stage of needing to enter all of my tools into the table before i can do offsets. perhaps if someone gave me a screenshot of the table so i can use it as a guide.....

There is no tool table as such, the tool table is normally in your CAM system, Mach only needs the tool length and diameter setting in the offset page.

now why couldn't anyone (i posted in many places) tell me that in the first place? THANK YOU!!!!!
can i ask another question?
i have looked at assorted videos regarding the offset procedures. all very well explained in terms of "how to do it", but nothing as to "why to do it".
do you have a simple explanation like you did for my first question?

p.s. i explain woodworking techniques to my clients (www.bois-exotique.com). i have come to understand that giving instructions or how to "do" things is fairly useless. instead, i explain the "why's" of things--from that point on, most people don't need "instruction interpretation"; they can figure things out.
thanks again.

All your tools will be of different lengths, Mach needs to know what the difference is between your reference tool (usually tool 1) and the rest of the tools, offsets do this, your reference tool has an offset of zero, each tool then has an offset that is the difference in length to the reference tool.

hi
i hate to impose on your generosity and patience, but i am desperate to learn and understand.
i saw the video showing how to use a reference tool, ie calibrate it. but i am not certain as to the reason for it.
when i used my cnc in the linux world, i would indicate a tool for a given tool path. when i ran the gcode, it would ask me to insert that given tool. i would then i let it run (i never did anything more fancy than vcarving or nameplates). so perhaps that is the reason that referencing to a tool or offsetting never was an issue.
it would certainly be nice if the folks at newfangled offered assistance by providing literature with information explaining the theories and concepts of cnc use with their software (reminds me of the first kawasaki motorcycle i purchased back in the early 80's--the salesman said "here's the keys, this is the clutch, this is the throttle, this is the brakes, and this is the gears. goodbye, good luck, enjoy!). it was a LONG ride home....  :-)
