Gmoccapy - A new screen for linuxcnc

Just pusher 1.0.9,

it solves a "Ignore Limit" bug.

Hi Norbert,

I went to use Gmoccapy today to turn some parts and the spindle readout is not the same.
In Forward I get the spindle speed of 500 rpm and a spindle at speed light.
In reverse I now get a negitive spindle speed -500 rpm with no spindle at speed light.

I have a back tool lathe it spends most of it's time in reverse.

Is this a change you have made?
Is this the way it will be from now on?
I have changed nothing in my config files except the disply section and
changes to posthui.hal required for Gmoccapy.

Hallo Jim,

I checked the spindle stuff and found some "strange" behavior, but nothing should have influence to spindle at speed, as this is linuxcnc internal, we just lit the LED when the spindle is at speed, I do not control that in gmoccapy again.

But I had several complains about the spindle bar changing its direction for reverse. So I took the opportunity to rework the spindle stuff.
Gmoccapy will from 1.0.10 (just pushed) only work with absolute spindle revs, as physically rpm is an abs value and should not be negative!

I needed to introduce a rt_component in postgui hal for that purpose.

Check and keep me informed.

Hi Norbert,

I did a reload and complete rebuild and I am still seeing negitive numbers.

Make clean etc.

When in MIDI mode I can set forward and reverse and I get a spindle at speed.

When in Auto mode I the spindle rotates but no spindle at speed light.

I am using the facingTOOL in NGCGUI with a surface speed of 500.

Hallo Jim,

where are the negative numbers? In the feedback bar? If so, this has influence also on the rest of the display, but not on the spindle_at_speed led. You must feed the spindle feedback bar with an absolut value.

Unfortunately your "hal snipped" of your post does not see all connections, as some abs are not connected and some signals seemed to be created on other parts.

gmoccapy 1.0.2

please update!!!!

- solved a bug in getting active gcodes, because I took also the first
element of linuxcnc.stat.gcodes, but that seems not to be a gcode, but
some kind of control number or something like that, so it causes wrong
code and changed gmoccapy behavior in an erroneous way, may also
result in wrong parts!
- In this bug finding I also needed to change the gladevcp widget combiDRO
to get the correct results

Sorry this was my bug!
