I think you are probably better staying with the XYZA configuration (it means all your G-code continues to work). Yes, it should be C, but the problem is that EMC won't run with B or C, only 'A' (unless I've messee up the 'ini' somehow, but I can't see it :-) If you want to stop changes in A value moving the tool in the preview display then all you need to do is edit the INI file GEOMETRY setting.

But then the 'A' word doesn't move the chuck either. I would like just to get the display sensible, leaving the mechanism the same. This is what the GEOMETRY setting does. It is separate from the COORDINATES setting. There are 3 semi-related settings in the INI file in the newer versions of EMC2 (your version might not use all of them) [TRAJ]AXES: This sets how far up the joints list we can go. This is the axis.N pins in HAL. where the X-word in G-code is linked to axis.0 and the W-word to axis.8. For reference the A-word controls axis.3 and C controls axis.5. If you want to use the C-word then you need to link axis.5 and that requires AXES=6. This hard link between G-code and joint numbers is likely to be removed in the future. [TRAJ]COORDINATES specifies which axis names are valid in the G-code. [DISPLAY]GEOMETRY controls the preview display. So, for your machine, using A you would have AXES=4, COORDINATES=XYZA and GEOMETRY=XYZ Using C would be AXES=6, COORDINATES=XYZC and GEOMETRY=XYZC (or maybe CXYZ). This would also require HAL changes. The full INI file docs for the current version are here: http://www.linuxcnc.org/docview/html/config_ini_config.html The corresponding doc for what I suspect is your version is: http://www.linuxcnc.org/docview/2.2/html/config_ini_config.html It is perfectly possible to upgrade EMC2 without upgrading Ubuntu, maybe even through the package manager. -- atp Torque wrenches are for the obedience of fools and the guidance of wise men -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

A refrigerator, generally doesn't get a GFCI, it supposed to get a single socket (round) outlet, to keep it from being used for anything else. It's far more hazardous to move a refrigerator out of it's hole (tipping hazard), to reset a GFCI, than the protection the GFCI is affording.

Let me explain in full: The application is to control a butterfly valve mounted in the exhaust of an engine to emulate the back-pressure from the production system including cat and particulate filter. The valve and motor (12V) already exist. The Dyno controller can operate the valve in closed-loop control (it is already controlling about 7 other process variables). It can output a voltage of up to +/- 11V and a current of +-25mA, but this is on a single wire which must be able to drive the valve actuator in either direction. The only power in the cell is 12V, 240V and 380V 3P. I have a feeling that a set of back-to-back power transistors could do the job linearly, at the expense of getting a bit hot, but an existing commercial solution would be best. The problem with the power-amp ideas is that that I don't see how that would drive the motor in the reverse direction, I think an H-bridge is needed. (unless we were to hold one terminal of the motor at 6V, and drive the other to 0V and 12V, I suppose) -- atp Torque wrenches are for the obedience of fools and the guidance of wise men -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

I was able to get a few as samples for the prototypes. I used a split supply to make the servo board cheaper (its a half bridge), and the common power supply more complicated. For a wiper motor, a supply of +-18v is very easy to make by taking a standard analog 12v supply and replacing the 2 diode full wave rectifier with a bridge and adding another filter cap for the negative rail. By the way, I was using car heater fan motors as brushed servo motors by adding an encoder. http://www.members.shaw.ca/swstuff/dspic-servo.html cheers, Lawrence VE7IT -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
