on my halcompil, i see the pin axisui.run-disable

The axis pins must be loaded after AXIS is fully loaded or else the pin does not exist error occurs.  Include them in another file so it loads later, like postgui.  hal or other.

 

Got the info together and placed it on github
github.com/ozzyrob/Linuxcnc-FPGA

Crickets ? A measure of lack of response ?

I already found the problem after two days, it was in the .HAL file in the various signal section, they had included the instruction halui.abort, but the truth is I don't know why this instruction changes from G54 to G53.

I think the problem is really because of the number of halui instructions within the file.  hal, as soon as I add an additional instruction of type halui, G53 appears at the beginning.  I don't understand why that happens.
 

This is an idea, without G41/G42, but it compensates tooldiameter from tooltable entry. Just enter the machining diameter near top.
Straight X move, then one round, and straight back to center.
You can do a helix also, just start at Z0, enter in the line with G2 also Z depth and amount P of turns (Z-2 P10)
Maybe G2 G3 can be changed for opposite direction.
It is not tested, so try careful dry run
Edit:
It is tested in my sim, and half circle lead in / lead out added for smooth transition to circle



 

You must mean 7I76E if you have CR17

CR17 is a SMBJ5V0 (SMB package)
Its job is to prevent overvoltages on the the
7I76Es 5V rail.

If PTC4 was fried that sounds like you accidentally
connected 24V to the 5V outputs on TB3. PTC4 is a
1206 2A PTC MF-NSMF200-2

Most likely hidden damage would be to 5V parts
U10 (serial), U12 (step/dir 0..3), U15 (encoder) ,
U19 (step/dir 0 ..3),  and U24 (step/dir 4)

Also if 24V got routed to step/dir outputs, the 27 Ohm resistor 
networks near the step/dir outputs may have been damaged
(check with ohmmeter, damage =  high resistance/open)

I feel really stupid asking this question.  I want to use G2 to cut a 1" diameter circle with a .125" end mill, with the center at (x,y).  There are tutorials on cutting arcs, on cutting rounded corners on squares.  There are lots of gCode generators that seem to produce nothing.  Can anyone tell me how tto write either G2 or G3 starting at (x, y) with diameter d feed rate 5?  IIf I have one working example, I will write a prograjm to produce the gCode for whatever size I need.  I am sure most of you can do this in your sleep.  I fear the stroke in 2014 took away too much analytic skill.

OP ?
Crickets...

Try oneshot or timedelay
linuxcnc.org/docs/stable/html/man/man9/oneshot.9.html
linuxcnc.org/docs/stable/html/man/man9/timedelay.9.html

Try this:

loadusr -W lube.py
or

loadusr -W ./lube.py
If that does not work, edit the lube.py file and check at the top there should be something like
#!/usr/bin/python
or
#!/usr/bin/python2
and change it to
#!/usr/bin/python3
save, try running LinuxCNC

In hal i think :
net just_a_name axisui.run-disable hm2_7i97.0.inmux.00.input-11-not

Then the python code is indeed stopping at this line when run-disable is active:
if comp : return

The name : axisui.run-disable looks ok to me.

I think you are almost there.

Hi,

Made a sample video of the progress so far for hal-core-2.0.

The gui sends the jog commands to the hal-component "state_machine.so" via shared memory.
Jogging is done by using scurve.
Motion speeds, acc, jerk, etc, is saved within the program settings tab. No ini file is needed so far.
Qt has a nice save settings framework, wich works ok.

In the state_machine.so component, all info is there to write the trajectory planner coming time.

So far the code is compact.

I have done this with and2 and works
but how can i give 1second delay to and2 output
so the hydraulic pump work 1s more after pressure switch triggered ?

Sorry to dig up an old thread but I have fried a 7I76 board due to connecting the end stop plug into the spindle connector and shoving 24V where it was never supposed to go!

Mine is a rev C board and PTC4 is badly scorched but still seems to be working. CR17 went short circuit and was burnt to a crisp which in some ways may have been a saving grace.

The FPGA is working and the voltage rails look good but the stepper buffers seem to be damaged.

I know I need to order SSOP versions of the 74ACT541 and 74ACT540 but what values are the PPTC and CR17? What else may have gone?

Finally is the schematic for the 7i76 available?
