I move this from from the "Plasmac Post Processors" subject as it has nothing to do with Plasmac Post Processors. 

One idea might be for you to be more specific.  What program did you export the tool library from?  It would probably be helpful if you posted the exported tool library here as well.  Otherwise it's impossible to help you.

~/linuxcnc/src/emc/usr_intf/halui.cc Line 894

The total program time could be difficult to estimate. This is possible to do so, but you need to do some calculations
over the entire trajectory.

It sounds simple, but i looked at the vertical scrollbar of the gcode file to get a indication of how far program is.
I did know how long a program usually took. 10-12 minutes for me.
 

@JT,

In a few post earlyer you mentioned:
Qt Creator is for C++ and Qt Designer is for python.

The qt designer creates .ui files that can be used with qt creator.

The link is broken:

Made a new link for you:

I want to say, i really like your work. A few years ago when i started linuxcnc,
i followed your gtk course gnipsel.com/glade/index.html.

I think you can also do widget overlay in the gremlin screen these days to show dro's.






 

I think it is not necessary, for that you can use the strobe signal, which guarantees the valid position.

Thanks for your feedback. Is it mandatory to connect the parity pin for a binary encoder? Because the parity pin of my encoder is not connected.For a bidirectional rotation I had the same idea by muxing the output numbers but you need to know if the first rotation is in cw or ccw. We'll wait for andypugh and hope he sees our request. As for the solenoid, watching the video in slow motion, I get the impression that it's activated when the pre-indexing sensor changes state. So your solution may be valid. 

Interesting, what Hal are you currently using to control that turret, could you share?
 

Thanks I got it fixed by poking around the wiring in the control board, couple loose wires that were giving intermittent signals I think.

Up to date with lcnc master :  lcnc repo

Then we now we can think about how to use this GENERAL MOTION. G9. stuff.

It has a lot off values we can use : x,y,z,a,b,c,u,v,w,i,j,k,p,q,r,e,l.
Normally the L is of type integer.

They idea is to create gcode like :

E= is proposed to be a identifyer for line, arc, etc.
L= is proposed to be a indicator for startpoint, waypoint, endpoint.
P = tollerance for G64
Q = naive cam value for G64
E100.1 or E100.2 is also valid identifyer. Really no limits over here now !!

# 3d Line
G9 E1 X0 Y0 Z0 L0 (start)
G9 E1 X100, Y100, Z0, L1 (end)

# 3d Arc
G9 E2 X0 Y0 Z0 L0
G9 E2 X50, Y50, Z0, L1
G9 E2 X100, Y0, Z0, L2

# 3d Plane, set current plane
G9 E100 X0 Y0 Z0 L0 (plane point one)
G9 E100 X0 Y50 Z0 L1 (plane point two)
G9 E100 X50 Y0 Z0 L2 (plane point three)

# 3d Circle
(set 3d plane)
G9 E3 X0 Y0 Z0 L0 (start)
G9 E3 X50, Y50, Z0, L1 (center)

# 3d Spline
G9 E4 X0 Y0 Z0 L0
G9 E4 X50, Y50, Z0, L1
G9 E4 X100, Y0, Z0, L2

# 2d Tri-Clothoid in 3d space.
(set 3d plane)
G9 E5 X0 Y0 Z0, I0, J0, L0 (where I=start angle, J=curvature begin)
G9 E5 X50, Y50, Z0, I0, J0, L1 (where I=end angle, J=curvature end)

So, we can just push multiple gcode lines into one object. Here we have no limits.
If you have any idea. Great!

Sampe G9 gcode that is currently running in TPMOD.so component :


G9 updating values.
 

My vtk error is on start up, any tool in the spindle, any (first) motion of the machine. The screen doesn't move the spindle indicator, and the error pops up. It does not drive the error until I move the machine. I can ignore the error and continue, but the backplotting screen never updates. I've only modified the toolchange subroutines.

Have you tried a larger distance to see if the ratio stays the same?

if its not a mechanical issue (backlash, loose couplings etc) it might be
marginal step timing or an electrical/wiring issue where the state of the
direction pin influences the step pin.

Hi guysI have not seen that anyone mentioned LCD display that can be connected to NVEM boards via serial port (small white)There is not much info on AliExpress


Could this be easily implemented to be used directly with board? 
I do not own it myself but more info if this is touchscreen with jog or just preview for DRO.

I will just leave it here for initial data collection

www.forum.linuxcnc.org/18-computer/42276...er-via-spi?start=790

post it here, maybe Scott will know, it is not entire obvious from the docs, but it looks like hes soldering it to something. Im not very familiar with the LPC boards

Hi,

The G9 is working. It is now running in the TPMOD from Rob Ellenberg.
It's showing a line, as i told the python part in lcnc to draw a line if it see's a G9.

Now the framework for a general motion is working!
Coding this, was not easy. But afterwards you can search for : GENERAL_MOTION and almost everything that
i coded into the source will appear.

To finalize it, i will also include I, J, K letters to pass into the G9. Extra variable letters already included are P,Q,R,L

One more question. Should I buy stlink adapter as seen in your ec500 video to flash EC500 or I can do this with USB to UART adaptor? How can I backup my original flash so that I can revert back of I need it. I have v5 version of EC500 with iMXrt 1052.

It would be great if you and terje collaborate in making grblhal working on this board. Its easily available and have plenty of io with MPG and Ethernet. One use as LinuxCNC or grblhal. I think this board is much better and cheaper than other options available. Also with 600mhz cpu.

im not really involved with the rt1052 project, i just do techsupport sometimes. I dont think it is optional, you need the stlink.

you can refer to this for flashing firmware etc,

This is my first post here so please bear with me if I am lacking any standard info or procedure in this post.

I have a 3 axis mill running linux cnc and need help diagnosing the cause for the distance difference in movement in the Y positive and negative directions. I have compensated for backlash, adjusted the scale factor, tightened the pulley, and oiled the table's lead screw but am still getting about 0.101" for every 0.1" in one direction and 0.98' for every 0.1" in the other direction. Any ideas would be greatly appreciated.
