Z - Zero not Setting to Zero.

Hi jlt206
Could you explain what you are trying to do while machining.
Unfortunately I cannot see the full screen to see if you have a temporary work offset in use or not. The best way to get a screen print is to use CTRL+P and it will copy the screen to the flash drive.
From what you have said it sounds like it has asked for a tool change and you have taken the new tool down to the material surface and pressed the Z zero button.
MASSO is not designed to work like that. The value you see on the screen is a calculation based on the old tool length, the new tool length and the original zero point of the axis.
If you want to use the paper method to change tools you will need to split each tool change into a separate files and run each individually.
The correct way to do a tool change in MASSO is to set up the auto tool zero feature. When you do a tool change it will bring the spindle to you where you can change the tool and it will then automatically measure the tool length for you and continue machining. It is very simple to set up and will make tool change a breeze. As a bonus you can use the same tool setter as a probe if you want for setting the initial Z zero height.

Hope this helps

Hi Peter,
is it possible to set up all of your tool length offsets before you actually run the program?
i usually plan the job and set out all of the tools needed in the proper order, then set up the tool length offsets, and other tool data, then run the program.
that way when the program calls for the next tool you load it in then resume machining and the offset is already stored in the tool length register. This is basically how I do that using a Haas mill

Hi Guy,
You sure can. That is what the tool table is for.
Many tool changes are run like this to eliminate the need to measure tools each time they are changed.
Measure each tool when you first install it in the tool holder and from then on then when you change the tool the length will be used from the tool table.
Just make sure that you turn Auto tool zero off or if you have set up an auto tool zero touch off for measuring your tools, put a check in the "Only measure tool when manually requested".
Hope that makes sense.

Hi Guy
In @jlt206 case I don't think he is using an auto tool change spindle so he can't use the tool table.
I could be wrong but I suspect that like me he is using a manual tool change setup similar mine.
To use the tool table the tool length has to be fixed and cannot change its measured length when installed into the spindle.
This is done by the tool holder in an auto tool change spindle.
In theory I could put collars on all my tools so they always had a fixed length but since the Auto tool zero touch off does everything for me anyway I don't see the point of complicating things to save a few seconds.

Thanks for all your replies... However...
I didn't use the tool setter as I'm having some issues with it, I don't have all the tools setup in the table and I don't use an auto tool changer.
I am just using the paper test for Z height for now, so an all manual interactive process.
The Tool height was set for the correct tool, for the first tool, but the program just stopped until I carried on with "Cycle Start" up until I reached the point that the controller then asked for a the tool to be changed. It was only then, that that I could set the new tool height, but until then it wouldn't accept it.
I'm going to go through the process a few more times, to better understand it.
One really annoying thing I found.. is that I couldn't view the G-code that was coming up. I also couldn't view mine in the editor as Masso says the file was too large.
I have actually viewed the videos, but sometimes they don't actually make sense until you get into the work.
It seems I just have more learning about the Masso controller and how it works from the code produced from Fusion 360.
Thanks!

In my case I am using tapered tool holders ( cat 40 ) and the whole unit is changed at a tool change call. I can set the tool length offsets before doing any machining and the lengths stay the same when the holder is in the rack or in the machine. That is the difference. You probably have a collet at the end of your spindle I'm guessing.

Just an Update...
After all my testing... Setting the Z height with paper during the tool change procedure was just not possible.
So I went ahead and configured an Auto Tool Touch Plate and a separately a Probe Plate, using the recommended Resistors this time.
This will work out better and I can get back to working now.
Thanks!
