Hey Norbert!

Thanks for the reply, Sorry I haven't responded as of yet. I will try to switch to a button to see if I get the same behavior. Where is the logic performed for Gmoccapy in reference to the E-Stop. I really like the design and will almost certainly be using this for my frontend.

I am replacing the computer I use to control the mill. I had a few complete freezes this past weekend. However I don't believe that this will be the culprit.

Did I mention I really like Gmoccapy? Also do you believe it will be possible to embed Linuxcnc-Features into a user tab? I have tried but failed at the attempt so far.

Thanks!

It is done in a combination of gladevcp, pytho status and gmoccapy.py.

Look in the gmoccapy.py file for on_hal_status as entry point.

Is it possible to get rid of the error i get when i embed the gearchange tab in gmoccapy, see the two images!





The gearchange tab is connected to the postgui hal with this code that runs an "M" file that changes the scale and offset in for the pwm gen.
Code:
postgui hal net vaxel-580 halui.mdi-command-16 <= vaxlar.hal_radiobutton1 net vaxel-2800 halui.mdi-command-17 <= vaxlar.hal_radiobutton2 net vaxel-1700 halui.mdi-command-18 <= vaxlar.hal_radiobutton3 net vaxel-160 halui.mdi-command-19 <= vaxlar.hal_radiobutton4 net vaxel-800 halui.mdi-command-20 <= vaxlar.hal_radiobutton5 net vaxel-490 halui.mdi-command-21 <= vaxlar.hal_radiobutton6 net vaxel-450 halui.mdi-command-22 <= vaxlar.hal_radiobutton7 net vaxel-2200 halui.mdi-command-23 <= vaxlar.hal_radiobutton8 net vaxel-1350 halui.mdi-command-24 <= vaxlar.hal_radiobutton9 gmoccapy.ini #16 MDI_COMMAND=M100 P580 Q-0.005 #17 MDI_COMMAND=M100 P2800 Q-0.002 #18 MDI_COMMAND=M100 P1700 Q-0.005 #19 MDI_COMMAND=M100 P160 Q-0.005 #20 MDI_COMMAND=M100 P800 Q-0.005 #21 MDI_COMMAND=M100 P490 Q-0.005 #22 MDI_COMMAND=M100 P450 Q-0.005 #23 MDI_COMMAND=M100 P2200 Q-0.005 #24 MDI_COMMAND=M100 P1350 Q-0.005 M100 file #!/bin/bash scale=$1 offset=$2 halcmd setp pwmgen.0.scale $scale #Scale halcmd setp pwmgen.0.offset $offset #Offset exit 0

Please try to connect the signals with a own hal file, called together with the gladevcp embedding function in the ini file.
Code:
gladevcp -c gladevcp -u hitcounter.py -H manual-example.hal manual-example.ui

-c = the name of the component
-u = a python handler
-H a user hal file, please connect here

Hello!
1) I have a problem with halui.spindle.forward/reverse/stop and gmoccapy.

in mu postgui_halfile.hal
Code:
net hw_sp_fwd halui.spindle.forward hm2_5i25.0.7i70.0.2.input-16 net hw_sp_stop halui.spindle.stop hm2_5i25.0.7i70.0.2.input-15 net hw_sp_rev halui.spindle.reverse hm2_5i25.0.7i70.0.2.input-14

When spindle is stopped and I press "hw_sp_fwd", spindle starts to cw. When spindle is running and I pressing "hw_sp_rev", spindle stops, but software button spindle CCW is active and target speed of spindle equal of zero.
When spindle is running and I pressing "hw_sp_stop" spindle stops through time
After some cycle pressing of hw button stop-rev spindle starts with reverse direction yet.

When I run the spindle from gmoccapy sowtware button everything works as it should.

When changing direction, the output voltage change the sign to target voltage for a short time and then output voltage is set to zero.


2) When in list of G code is G95 and F0.1. The seted value of feed is zero. When F1.2 setted value of feed is 1.
I corrected it:
Code:
def _update_vel( self ): # self.stat.program_units will return 1 for inch, 2 for mm and 3 for cm real_feed = float( self.stat.settings[1] * self.stat.feedrate ) if self.stat.program_units != 1: self.widgets.lbl_current_vel.set_text( "%d" % ( self.stat.current_vel * 60.0 * self.faktor ) ) if "G95" in self.active_gcodes: feed_str = "%s" % self.stat.settings[1] real_feed_str = "F %s" % real_feed else: feed_str = "%d" % self.stat.settings[1] real_feed_str = "F %.d" % real_feed else: self.widgets.lbl_current_vel.set_text( "%.3f" % ( self.stat.current_vel * 60.0 * self.faktor ) ) if "G95" in self.active_gcodes: feed_str = "%s" % self.stat.settings[1] real_feed_str = "F %s" % real_feed else: feed_str = "%.3f" % self.stat.settings[1] real_feed_str = "F %.3f" % real_feed # converting 0.0 to string brings nothing, so the string is empty # happens only on start up if not real_feed: feed_str = "0" real_feed_str = "F 0" self.widgets.lbl_active_feed.set_label( feed_str ) self.widgets.lbl_feed_act.set_text( real_feed_str )
i.e
Code:
feed_str = "%d" % self.stat.settings[1] change to feed_str = "%s" % self.stat.settings[1] real_feed_str = "F %.2f" % real_feed change to real_feed_str = "F %s" % real_feed real_feed_str = "F %.4f" % real_feed change to real_feed_str = "F %s" % real_feed
and
Code:
if not real_feed: feed_str = "0" real_feed_str = "F 0"

How add hal pins to correct control the spindle (and coolant, mist)?

I am pretty sure, that that is caused due to non perfect Hal connections.

if you do:
setp halui.spindle.forward 1
setp haluie.spindle.stop 1
setp halui.spindle.reverse 1

you will get problems, because the halui pin do only react on getting high.
setp halui.spindle.forward 1
setp halui.spindle.forward 0
setp haluie.spindle.stop 1
setp halui.spindle.forward 0
setp halui.spindle.reverse 1
setp halui.spindle.reverse 0

will work. Do you use momentary switches?

2) When in list of G code is G95 and F0.1. The seted value of feed is zero. When F1.2 setted value of feed is 1.

I just tested on gmoccapy 1.6.0 and if I enter in MDI G95 F0.1 I do get F0.1 and if I enter G95 F1.2 I get F1.2
I tested in metric and imperial units.
Or do you refer to the F value in active gcode?

Please check from MDI and tell me if that does work.
What version of gmoccapy do you use?
