expected program runtime searched was created by chris@cnc

Hello,
The expected program runtime can be seen in file -> properties. Is there a way to export this signal to Pyvcp? I want to run my program runtime timer backwards and need the expected runtime for the calculation.

First - to you quiestion - I don't know. Second - the estimate is very very poor.

The estimate is very precise, it just does not include anything except the feed distance at the given feed rate. So rapids, tool changes, acceleration/deceleration, probing, etc are not included.

And that's the point. I don't have a tool changer. And so it's good to know when to be back. 5 minutes don't matter. But I have 4 cores and I no longer want to do their work. They are better at calculating and with a little offset the estimate fits usefully.

For Plasma, since there are probing and waiting for the arcok signal besides the rapids and accel/decel, i just double the value that i get from file>properties.
It usually is near enough, but when it has to do a lot of pierces/probes/waits i tend to triple the time. That requires a bit of experience with the machine and types of work.

I found the calculation of the estimated program runtime in /usr/bin/axis from line 1964 to 2018. Could someone point me to the variable where this time is written?
I would export to the pyvcp panel and calculate backwards to zero

def gcode_properties(event=None):
        props = {}
        if not loaded_file:
            props['name'] = _("No file loaded")
        else:
            ext = os.path.splitext(loaded_file)[1]
            program_filter = None
            if ext:
                program_filter = inifile.find("FILTER", ext[1:])
            name = os.path.basename(loaded_file)
            if program_filter:
                props['name'] = _("generated from %s") % name
            else:
                props['name'] = name

            size = os.stat(loaded_file).st_size
            lines = int(widgets.text.index("end").split(".")[0])-2
            props['size'] = _("%(size)s bytes\n%(lines)s gcode lines") % {'size': size, 'lines': lines}

            if vars.metric.get():
                conv = 1
                units = _("mm")
                fmt = "%.3f"
            else:
                conv = 1/25.4
                units = _("in")
                fmt = "%.4f"

            mf = vars.max_speed.get()
            #print o.canon.traverse[0]

            g0 = sum(dist(l[1][:3], l[2][:3]) for l in o.canon.traverse)
            g1 = (sum(dist(l[1][:3], l[2][:3]) for l in o.canon.feed) +
                sum(dist(l[1][:3], l[2][:3]) for l in o.canon.arcfeed))
            gt = (sum(dist(l[1][:3], l[2][:3])/min(mf, l[3]) for l in o.canon.feed) +
                sum(dist(l[1][:3], l[2][:3])/min(mf, l[3])  for l in o.canon.arcfeed) +
                sum(dist(l[1][:3], l[2][:3])/mf  for l in o.canon.traverse) +
                o.canon.dwell_time
                )

            props['g0'] = "%f %s".replace("%f", fmt) % (from_internal_linear_unit(g0, conv), units)
            props['g1'] = "%f %s".replace("%f", fmt) % (from_internal_linear_unit(g1, conv), units)
            if gt > 120:
                props['run'] = _("%.1f minutes") % (gt/60)
            else:
                props['run'] = _("%d seconds") % (int(gt))

            min_extents = from_internal_units(o.canon.min_extents, conv)
            max_extents = from_internal_units(o.canon.max_extents, conv)
            for (i, c) in enumerate("xyz"):
                a = min_extents[i]
                b = max_extents[i]
                if a != b:
                    props[c] = _("%(a)f to %(b)f = %(diff)f %(units)s").replace("%f", fmt) % {'a': a, 'b': b, 'diff': b-a, 'units': units}
        properties(root_window, _("G-Code Properties"), property_names, props)
