I kind of figure out what your saying above the more I looked into it. As a beginner we tend to forget that if your move the tool in .005 your actually cutting .010 off the part on a manual lathe. Here the CnC software takes into consideration the Mode your in and compensates.

If I setup all 12 tools I use as per the manual and go to setup a work piece that uses only 3 tools. Do I need to set it up off of the master each time or can I setup off a tool it will be turned with.

Example . I use a general turning tool Angle Right Diamond shaped as #5 tool and a Drill as #10 and a cutoff as #3.  My operation is drill a hole with #10, then turn a chamfer on the end and turn down the OD with #5, then cut off with #3. Its all in the code to do tool changes and it works as its supposed to but I always setup off of #1 even if I'm not using #1. Can I setup off of any tool I'm actually using or is it best to setup from the master.

Setting up a drill chucks. If I set up a drill chuck I need to make sure it's aligned with X0.0 and not on an angle so it drills straight and does not taper the hole or worse bind and snap a drill. what is the recommended way to square the tool post with the lathe chuck?   What I have been doing is put a piece of drill rod in the chuck loosen the QCTP and the move the drill chuck onto the drill rod and adjust and tighten it all down, Then go and setup all the tool starting at master and working my way to #10 drill #11 drill an #13 boring bar. Is there an easier way to set up drill chucks?

All good info, You are correct the better you setup your tool the less you have out of tolerance issues, but being a novice I'm prone to beginner errors and bad methods just because I don't know better.

I'm on 062 now and in the lathe > Auto > Cycle , there is a button just under the code window that says "Tool Adjust". In some documentation  it mentions it but only in one sentence, basically this is where you do that adjustment but no reference as to which dro or how to enter i.e... diameter, radius, half number or full number.

I wanted to use it for making adjustments on the fly as I run a job of 100 or so items. I setup the job and tooling as per the manual then run a few and make the adjustment and run a few more an see where it is, if it's good I check every 10 - 15 and adjust if needed. but as I said its mainly due to me being a nube on CNC and most likely not having setup correctly. I did find some backlash issues that I corrected that also contributed to the variances.

For all the new guys I found that there are a few ways to do tool cut adjustments on the fly. The easiest being "Tool Adjust" and enter the desired correction into the wear field off either X or Z
This is for lathe front tool post in diameter mode.

After you setup your tooling and make a few test runs, you can enter the needed adjustment or as your turning a run of parts and periodically need to compensate for tool wear or other anomalies on the X or Z axis. Enter the whole number of the difference between the cut and measurement, if it's 0.005 larger in diameter you need to enter -0.005. if its 0.005 to small enter +0.005. + brings the tool out toward you and - brings it in away from you. Z is the same thing.  Anything to the right of Z0.0 will be + and anything to the left of Z0.0 is -

The entries for a tool in tool table are added up for in each tool to give you the offset or position of the control point. Using tool wear does not change the base offset for any particular tool it just adds to or takes from that tool. So changing the #1 master tool by using X Wear does not change how you set it up in tool table as Z 0.000 X0.0000 and does not change the relationships between master and the other tools, that remains unchanged. If you enter for the master #1 tool 0.0015 in X wear you will see the Z0.000 X 0.000 stay the same and X wear as 0.00075 and it will cut the the part larger by 0.0015. 

You just need to remember you have a wear entry in the table when setting up for another job or changing the inserts

General Mach Discussion / Re: Threading Wizard

I had the very same issue, It turned out to be a corrupt license file. I closed the program and re installed the license and it worked, It will not run line 7 in demo mode or without reading a valid license.

The other question is when I make a change to the master does it make the change to all tools or do I change each individually.
I'm thinking more of changing on the fly to dial in the part being turned.

General Mach Discussion / Mach3 Turn Master tool setup, Tool Adjust
« on: July 17, 2017, 02:26:26 PM »
I'm very new to Mach3 and I have searched all over and looked in the support docs and the Turn manual for information on the tool adjust button to no avail. Its briefly mentioned in many places but nothing specific as to how you use it and what field you put the changes into.

I setup all the tools as per the instructions, and I understand all that. But when I setup the master tool or any tool the lathe and take a cut, I measure and see there is a difference of lets say +0.003 (part is larger that it should be) between where the software thinks the cut was and what it actually ended up with.

I assume tool adjust is for this purpose but which of the 10 fields do you put the change into. Wear.. offet, ? I'm in diameter mode so I would half that number to 0.0015, I got that. 
I'm on 066 and realize it has an issue with some turn functions. I will be reverting to 064 or 057.

I'd like to get your screen set, I pm'd you last week
