Hi
Video Address:  http://www.youtube.com/watch?v=_8apTgMTvjI&playnext=1&videos=srC9h9H00Ps&feature=mfu_in_order

I have  tooling holders by Tormach that I`m using in my DIY router. I have gone over
the details of tool offsets in the above video. At this time I do not have the Tomach dial indicator
mounted in a holder. As a substitute I used a long drill bit mounted in a holder.
I setup tool 1 i.e. a long drill bit as the datum tool. It was placed on 123 blocks.
I brought the spindle down to the top of the 123 block and set in Mach3 that point
as zero.
I then found the top of tool1 and got a measurement of 5.2766

Tool2= 5.2356

Tool3=4.3434

Tool4=2.2066

Tool5=4.1271

 

I then loaded my code into Mach3 and brought T1 down to the surface of the part.
I set xyz to 0.000
I manually moved the machine from the part to allow for a manual tool change.
I placed T2 in the spindle and ran the program.

Problem: Tool2 raised extremely high over the work surface triggering my Z limit.
I have no idea why the second tool raised so high when it was a bit shorter the T1
I have a clearance plane set for .2 above the surface. Still the tool seems to be moving
just too high.

Do you have the safe Z enabled and set up as an incremental move?

Hi
Here they are. I didn`t find any tool.dat files in the macro folder but did in C: Mach3 main folder.
I hope I attached the right file.

Hi
I got a email from Tormach. They mention to call a tool changes as follows: T2 M6 G43 H2.
I have T2 M6 and G43H2 on separate lines. At the beginning of Tormach code they have a
G28. I do not. Are any of these differences causing the problem.

Just a thought , If the master tool (drill bit ) is the longest tool then all the rest will be - numbers when doing the measurement.  If you put in + values then mach thinks they are longer and raises the spindle??
