You can set the tool change position to be anything you want, but the machine needs to be homed once when you start EMC, so that that position can be repeated every time you start it up.

I already have one. It's good, but it has problem, that you can not see, which reference voltage you have set. It happens than, that if operator set voltage too low, than usually after start, the torch hits table.

There is still one watchdog pin active and it is FALSE and I can't
seem
to set it true.
If by inactive you mean non-functional that would be just fine.
However, there must be something getting in the way of servo analog out.

Indeed! I am quite dismayed by the apparent fact that this doesn't
just take off and run.
More to the point though there doesn't seem to be anyway to easily
debug the thing unless
you are good at hal which I am not.
Oh, well, off to watch a US First Robotics meet and then to the beach
for a couple of days.
Maybe this will look less daunting when I get back.

HI Jeff - on the subject of home, why was the behaviour changed to force a home in 2.3? I found the NO_FORCE_HOMING=1 in the wiki. I'm trying to get my head around how to make AXIS and EMC behave like I'm used to with Mach Turn before trying it for real.

I don't use them during tool changes I do my tool changing just far enough off the end of the stock so the longest tool doesn't hit the stock, really a waste of time to travel any further ;) X0 is always the centre of the stock, Z0 is nearly always the end of the stock. My method is to jog to the end of the stock, touch with tool1( tool1 has no tool offsets) and Zero Z, then jog and touch the side of the stock and enter the stock diameter in the X DRO. (It's possible to type and enter data via the DRO's in Mach). I would then simply run the file. How do I do that? Touch off seems to mess with tool table?

Hi list, Would "serial_dac.comp" be a good starting point for making a "SPI.comp" or do you recommend anything else to start from? Maybe there is something written already?

Re: [Emc-users] compile problem in lenny
You are missing various important prerequisites to build emc2. RTAI is the kernel with real-time extensions required by emc2 to control machinery. A user has contributed instructions on building it on our wiki: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI The same user has also contributed instructions to install packages emc2 depends on, then compile emc2: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_EMC2 The packages listed in debian/control.in in the source tree can also be useful in determining the requirements to build or run emc2, though that file refers to ubuntu package names rather than debian package names; the two sometimes differ. If you find any mistakes in the wiki instructions, please update them.

The problem is that I can not set the tolerance on the CAM side the way I like. I use DeskProto and DP uses a raster to 'scan' an STL model and create the G-code from there. There is no way to tell DP to follow lines in the Z-height with a certain precision, it just follows lines in the X direction with a given step size in the Y direction to derermine the Z-height at each point. If only they would have made it such that I could create lines in the X-direction and tell DP to follow the contour with a given precision that would have been great. DP has different algorithms for different purposes but just not the one that I mostly use. I already thought of writing my own software for this special case and maybe I should just try.
