To touch the tool off I am physically cutting an OD, measuring that diameter
and touching off the tool using that mic’d measurement, so the “actual tip” as
you say. So, yes, we are cutting a tiny bit deeper.
However, what we were seeing (and have seen multiple times now but cannot yet

That should be fine then.
Something different:
I see that the hm2_rpspi module is

There are actually two lines
Ok, I set up simulated home switches, It will home all of the axis without
setting any alarms, and after homing I can jog the W axis. But I still can't
jog the W when I first open Linuxcnc using the on screen jog buttons. But I
can jog it before homing using the [ ] keys on the keyboard. If
How are you touching off (or otherwise determining the X tool offset for the
insert)?
For example, if you calculate the offset assuming a sharp-V geometry (the
simplest case), but touch off with the actual tip of the insert (not sharp),
the insert will be in deeper than LCNC thinks it is when
Ok, thanks for the responses. I found some thread gauge wires and with them
have determined that we are cutting too deep. This would cause the pointy
peaks and root, so the next question is why are we cutting too deep…? We
believe we are entering the correct value for K (thread depth) but I

If the proper geometry is important then you may want to consider using full

If this is a 3/8 x 24 then I assume it is a UNF thread.
As I understand it, UNF (and UNC) threads are part of the UTC system, but the
specification for UNF and UNC threads is that UN threads typically have a flat
root, with the option of a rounded root. The rounded root simply gives more
As that one has a range then you turn to final diameter ans dont go
too deep with the insert, that leaves a flat on top.
Measure on the job with thread wires etc to check depth.

They are made to class 2 or perhaps even class 3. I know
