Material surface height Vs Toolsetter

I have watched Peters video on How to set up a Toolsetter in Masso - Episode 017 and found this very good. At least it worked fine for me. My question is after setting tool length at start up how does MASSO know where the surface of the material to be worked on is when the height of the material changes ? What have I missed?

Hi @supman

MAGIC ;-)

The tool setter is a fixed height as is the material. When you set Zero point of your tool to the material the difference between this height and the the tool setter block is saved. The relationship between the 2 doesn't change unless you move your stock or Auto tool Zero block

In future tool changes the new tool is measured against the block and since it knows what the new tool length is and what the offset is between it and the stock, Masso can work out the actual zero point of the new tool.

In our school days it was call Mathematics.

Hope this helps

Cheers Peter

Yes as when i did mathematics at school (a long time ago) there was 2 parts minimum to work out a answer. As above. All I need to do is set the zero point of the tool to the material. "Voila"

the setting of the zero point of tool to material. can this be done at any time?

Hi @supman

There are 2 parts to this equation as well. The first part is homing to measure the current tool length and the 2nd part is zeroing the Tool to the stock to work out the off set.

All you need to do is set the tool to the stock and zero the Z axis after homing and before you start machining. you can set the Zero either manually or use the probing function.

This video shows the basic process.

supman,
the setting of the zero point of tool to material. can this be done at any time?

Anytime after tool has been "Zeroed" by ATZ. Once tool has been "Zeroed" don't change tools unless instructed by MASSO to do so. Either because of tool change in Gcode or by you issuing a T0x M06 command in MDI.

Hello.

Is there a way to set a soft limit to prevent the cutter diving into the bed of the machine by telling masso the height of the tool height sensor? Lets say the sensor is 16mm thick and you place it on the table. A soft limit could be set at -16mm from the machine height when zeroed from the sensor, yes? Is there a soft limit to prevent tools hitting the table? Where is that set?

I would assume that as material thicknesses can vary that mistakes could be made. For example Program 1 has a material thickness of 20mm and so you set the cut depth at 20.5mm cutting into your waste board 0.5mm. You then change jobs and put a 4mm sheet of acrylic on the table. You prob it so the machine knows the material height and then accidentally run Program 1 instead of the intended Program 2. The machine then cuts 20.5mm from the top of the acrylic which sends it through the wasteboard which is only 12mm cutting into your table (20.5-12-4) 4.5mm. Ouch... But we have a controller that knew the tool height and bed height so it should be able to prevent this. So the question is since we know the height of the tool above the table is there a soft limit to prevent us diving the cutter into the table. If so where do you set the height of the tool height sensor? If not how do we make a request for this to be a feature?

Thank you.
