In Masso you are able to set up Soft Limits. When you configure your soft limits you will not be able to do anything in that area, except for change tools. 

When configuring a soft limit area along the Y axis, it is along the full length of the Y axis, and the same with the X. If you home in the soft limit area, you can still jog around there, however once you leave, you cannot re-enter. In the picture the yellow rectangles are your soft limit options. 

 

 

With this information, here are some example tool rack layout ideas, and they can be mixed and matched as far as positioning goes, but you cannot mix and match tool rack heights. 

 

As said in the Flush Mount KB article, the flush racks are not best suited for a Z-Dependent boot, and are best suited for no boot, or Z-Independent boot, as long as the lowest obstruction of the boot clears the top of the tool holder, and other nearby tool holders. 

 

Conversely tall racks are best suited for Z-Dependent boots where they rise and fall with the spindle. The objective of the Tall is to bring the tool holder to an elevated position. The following picture is an example of a using a tool rack without a boot or with a retractable / automatically removable boot. 

  

 

If the boot is fixed position, like our v7 or v10 proper spacing needs to be given between to allow for the boot to capture and release the tool holder without coming in contact with any of its neighbors. 

In this picture, I show you various pickup/drop off locations, and the example boot brush track is for a 4", but if you have a 2.5" you can still apply the same principal when planning your layout. 

 

If however you use our v7 - Narrow Brush Track or v10 - Narrow Brush Track you will need to add even more spacing, however as with any option your also able to add more columns along with more rows.

 

The advantage of the pick and place tool racks is that you're able to put them anywhere you want, the disadvantage is that it takes up workspace. 

 

Here's several angles of the different options on one workspace for reference, the workspace shown is 48"x48"
