Changing the tool length in a macro

[jjude]

Hi

I measure the tool (M6).
I run the gcode.
I want to set the tool length to be shorter.
How can I set the tool length to something other than what was measured?
I run the same code and get the "deeper groove" I want

You could write the value in the tool length ofset field using AS3.Setfield and AS3.validatefield.
Please check the UCCNC/Documentation and macro capability document about the syntax of these functions.
You could check the DRO number using the built in screen editor of the UCCNC, just open the screen editor, click that DRO and check the fieldnumber parameter in the screen editor.
Then use that number in the setfield function, you could write any numbers you want into the DRO from your M6 macro.

if just using one tool, adjust your z height by the difference. (change number in z dro)
to go deeper add the difference
to go shallower - the difference

Hi everyone,

I have a quick question regarding adjusting the tool length during a macro. When I try changing the tool length using the Z DRO value, I'm unsure of how exactly to calculate the "difference" in the Z height for different tools. Could someone explain how I can determine this difference more accurately?

Thanks in advance!

do you have a tool length probe added to your machine?
if not you would have to jog to a fixed point and subtract the z dro readings

if machine is single tool, just jog new tool down to your zero plane and zero the z axis dro (same reference point as previous tool)

Many Many Thanks.

I don’t have a tool length probe, so I’ll try jogging to a fixed point and subtracting the Z DRO readings. For single tools, I’ll make sure to zero the Z axis DRO at the same reference point.
