I never have any trouble with it. Smiley

Here is the full tool change code where the tool number is 11. Most of you guys know this.
T11 M06 G43 H11

Here is the video I promised as well. All setting are very conservative.

The M01 wasn't what was missing.
It was the actual M06 with the tool number in front of it.
The tool number in the parentheses is what was throwing me. That don't count. Wink At least not as Gcode.  Roll Eyes

I have found some documentation on some of the control parts like Drives on the Novakon site, but haven't even searched for the BOB yet.

I did manage to figure out how to get it to stop for tool change though. A simple M01 command after the move to tool change position is all that was needed. That is provided that is checked in the General config screen. Smiley

So all that is working and I am just filling in my offsets now, so I should be able to run a few parts fully on the machine later today.
I have been manually drilling and tapping these parts for years now. It will be nice to finally let a machine do it.

Novakon is coming out with a PDB and an ATC that I will need to save some pennies for. That would be a very nice upgrade.
Thanks, Hood.
I'll post a video when I have something.

I'm not sure what it is.
The manuals are not ready for these machines yet. I don't recall what the labeling on the BOB said if anything.
I do have a picture I think, but not that great.
The switch is the little black slider in the lower left.

Here is a code snippet, BTW.

I have different tool numbers, so Mach should stop. I have it set that way in the general settings.

Great thread, Guys. Nice machine too, Hood.
I recently received a Novakon Torus. It can do rigid tapping too and I have been working with John at Novakon on it.
Sheetcam outputs nice rigid tapping gcode, but when I try it in standard Mach, once at the bottom of the tap, the spindle starts a few thousandths of a second before the Z starts lifting. That is a crying shame.

This machine has a servo spindle and it has a switch on the BOB.
You don't have to flip the switch each time, but I keep it switched to tapping.
It still does all other milling and drilling well too.
That switch makes it like the spindle is the A axis I think and then A and Z are synced with some code snippets that are adjustable.

I have it all working on my first test tapping run now except that I cannot get it to stop in between the drilling cycle and the tapping cycle. Mach stops at tool change fine earlier in.
Is there a code snippet I can use to force Mach to stop and stay at the tool change position?

I'll post some video when I get it doing right.
Thanks in advance.

Approaching those stops slowly will likely help with accuracy, but go at them a bit too fast and that is where the discrepancies normally appear.
Mach has a slow down function when approaching a switch, which is nice.

I haven't setup any switches on mine other than Estop.
You would really have to have some accurate switches in order to set it up as precisely as the tool zero. I fire mine up in the morning and zero to the tool zero. By the end of the day, its still within tolerances for my parts. Not so sure that would be the case if I used home switches.

The tool table reflects my offset travel in each direction. It has the actual distance loaded in the tool tables from zero.
However, if you are at the tools offset and hit that tool number, it will show zero. A bit confusing, but it makes sense. Stay at your main tools zero and then pull up different tool numbers. You should see the offsets appear in the DRO's.
