Hi Vlad,
Ouch!
But I don't think your main problems were related to the amount of buffering. Although maybe Mach3 has an issue with buffering Jog Keys? What jog mode were you in? Step or Velocity?
But with regard to estop, I think the best approach is to have it hard wired to a contactor relay that will kill power to all drives.
The estop input to Mach3 should cause it to turn off all the Drive Enable Outputs. Are those wired to your drives? But all this relies on Windows, USB communication, and KFlop to be responsive.
Limit Switches should be wired to KFlop and configured in the axis configuration to "Kill Motor Drive". This will disable the axis which will stop generating pulses. This should be instantaneous regardless of the state of Windows, Mach3, USB, or any buffering.
Regarding jerky jogging. There might be an issue where if the Jerk setting is so low that it is impossible to reach full acceleration without exceeding max velocity that the motion blending has problems. Try increasing the Jerk to see if it works better.

I have noticed that even though Mach is in "reset mode" (reset flashing) it is still possible to jog with the arrow keys when using the kflop. I have been meaning to try a work around that I think will work. My idea is to use a brain in mach3 to sense when the reset led is flashing and inhibit all the axis then enable the axis when the reset has been cleared (green). Not sure if it would work but the theory is sound :)

Hi Allen,
Mach3 still sends Jog commands to the plugin while it estop mode. We could change the plugin to ignore them if in estop. Would that help?
Normally it shouldn't matter because Mach3 disables the amplifiers when in estop anyway.

If you could do that then yes that would be very helpful. Just upgraded a stepper system last week and those drives are always enabled so it was possible to jog while in estop.

Hi Allen,
Here is a Mach3 Plugin compatable with V4.23 that:
Disallows Jogging while in EStop
RESET will now immediately halt any motion
External EStop will now immediately halt any motion
Please let me know if you find any problems.

I get an error when starting Mach3 that the plugin is defective and that it will ignore it. The file size of this plugin is much smaller than the current one.

Hi...
Safety should never be done in software. There are a FEW pieces of software running on even fewer platforms that are safety rated.
I worked on a machine that had safety in the controller, it passed all tests until the firmware was upgraded. The machine then failed to respond to stop inputs and worse yet e-stop. Luckily, no one was hurt and the machine only did $50,000 worth of damage to itself before some one could jump on the main disconnect.
It's a good idea to have an e-stop on a long cable sitting next to you programming station as you work. I like to have a box with an 'e-stop', 'resume' and 'cycle hold' in it next to the keyboard.
PLEASE don't do safety in software.
