Hi,

I'm probably missing an obvious example, but how to do you get KFlop to display a message box in KMotionCNC asking for a value?

I'm working on my turret recovery program, and I'm wanting to ask the operator for a position to attempt to change to, then use that value within the KFlop program.

Also, are there any examples for setting tool offsets by taking a test cut then entering the actual value?

My final major job before getting my lathe fully working on KMotionCNC is some way of setting the tool offsets easier. I'll admit I've not had a chance to look at any of the offset functionality in much detail, but was wondering if there are any examples to get an idea of the process involved.

Thanks,

Moray

 

I knew I'd seen an example somewhere. That'll tech me for not looking past the MessageBox examples.

I've always classed them tool offsets on the lathe, but you could class them as tool lengths.

What I'd like to implement is something vaguely similar to the tool setup in Mach 3 turn.

The basic process I have in mind is -

Jog to a suitable point

Take a test cut.

Measure the test cut

Enter the actual size into a pop-up box

Offset is then calculated and stored into the tool table

Mach3 does it by entering the value into a DRO, and then using a Touch X/Z button to set the current tool position and update the tool table.

The critical axis is the X.

I normally just rely on visually touching of the Z, but a similar technique and entering 0 for the actual size will work.

Thanks,

Moray

Hi Moray,

See the example MessageInputBox.c

When referring to tool offsets do you mean length?  I suppose not as you have a lathe.

So I've done a bit reading up on tool offsets, and from previous posts I've gathered the following points-

Within G-code any number below 100 is assumed to be a slot ID, with 100&above a tool ID.

The M6 command within KMotionCNC transfers the Slot ID in the chosen VAR and the tool ID in VAR+1 (which in my case I'm using 7, so Slot is in 7, and ID in 8).

Would it be correct to assume that all tool table values are in imperial/inches?

And given I run in metric, I'll have to convert values before storing them in the table?

I'm wanting to make sure I understand the basics before I start work on the on any code.

Thanks,

Moray

Moray,

I think you'd have to code something along the lines:

#1 Read the X DRO
#2 Ask Operator what it should be
#3 Compute a correction (ie difference)
#4 GetToolOffsetX
#5 Adjust it
#6 SetToolOffsetX

See the ToolTableSet.c example

My plan was to use 100 and upwards in g-code, as that way I don't need to continually swap Slot numbers in the tool table when I change tools. The same tools usually go in the same slots, so all I need to do is swap tools and adjust the necessary offsets (typically just length for drills, as the turning tools rarely get changed). Would this work?

So if the offset values are unitless, what happens if I was to set everything up in metric/mm, then load an imperial/inches (G20) g-code file?

I always work in metric, but I'm curious as to what would happen in regards to tool offsets.

Thanks,

Moray

Hi Moray,

Yes tool numbers 100 and greater are assumed to be IDs.  I would think you could just use the specified Slot number regardless.

No.  Tool table values and fixture offsets are just unit less numeric values.  They are assumed to be in the same units as the context they are being used.  You can request the current units that the Interpreter is in as shown in the example by calling:

    GetMiscSettings(&Units, &TWORD, &HWORD, &DWORD);
