Save position after AXIS shutdown
Putting in POSITION_FILE = position.txt doesn't seem to cause that to happen nor does a fully qualified path name. Is that supposed to be how it works and is there any place to see a message that might explain why it didn't if so?
EMC V2.4 Integrator Manual Chapter 4. INI File
NO_FORCE_HOMING = 1 The default behavior is for EMC to force the user to home the machine
before any MDI command or a program is run. Normally jogging only is allowed before homing.
Setting NO_FORCE_HOMING = 1 allows the user to make MDI moves and run programs without
homing the machine first. Interfaces without homing ability will need to have this option
set to 1.
Warning: Using this will allow the machine to run past soft limits while in operation and is not
generally desirable to allow this.
In the Traj section of the ini file set NO-FORCE-HOMING = 1 this will llow you to start your machine at the saved location without homing.
Otherwise it will still help when I have a part that is going to be in the vice over a few nights and shutdowns.
One strategy that I use is to initially start the machine and home all axis. I then jog to the position I want to work, say the lower left side of the work zero height. I then use G92 to set all my axis at 0 (or the position I need). You can then perform your work from this position. When done use G53 G0 x0y0z0 and the machine will return to your original homed position. If you look at the DRO it will show relative numbers for xyz from home to your work position. These positions will be stored in the position file. When you restart EMC these numbers will appear, you can home to them. Then G0 x0y0z0 to the position you left off at. The soft limits will now work. The G53 move has the benefit of verifying that your machine is in the correct machine position on your indexes when you start.
Next up I need to map my screw for better accuracy with the acme nuts till I have the equipment to get ball screws installed.
Thanks for all the assistance. I have really been enjoying the machine and you guys have helped greatly in getting me started with EMC. I really appreciate all the tips, suggestions and help.
