net negated-encoder-out comp.0.in1       # Connect to comparator input
net encoder-threshold-met    <=    comp.0.out   => and2.1.in0

then, when the command is executed -
M64 P3
G38.3 F15 Z0

the machine does not respond to the sensor.

And in the usual configuration -
        net probe-in        <= parport.0.pin-13-in-not
        net probe-in => motion.probe-input

the sensor is triggered, the machine understands this, but sometimes there is an error "non-probe mode"

What am I doing wrong?

Can you show a bit more about how the enables are wired?

What is OUT0+ (TB3 pin 14) connected to?

Why do you need a PC with a parallel port?
PCIe parallel port cards are great and very cheap.

I have an extra SUNIX parallel port card; they work quite well for CNC control.

However, it uses a highly inefficient 7805 voltage regulator, guess you get what you pay for!

I'm glad you managed to fix it.

Define "sort of worked".

This option completely ignores the sensor operation G38.3 F550 Z0!
loadrt flipflop count=2
addf flipflop.0 servo-thread
addf flipflop.1 servo-thread
setp flipflop.0.set FALSE
setp flipflop.0.data TRUE
net probepin parport.0.pin-13-in-not => flipflop.0.clk
net probereset motion.digital-out-00 => flipflop.0.reset

My simple task is to find the bottom when the sensor is triggered, to move away from the found bottom without triggering an error "non-probe mode error" 

 

yes.
in the second option it was necessary to add -
loadrt flipflop count=2
addf flipflop.0 servo-thread
addf flipflop.1 servo-thread

LNCNC started without errors.

However, the scanning program worked crookedly - the probe reached the workpiece, rested on it and went to the side.


but it’s not yet possible to launch the first option; I don’t know which loadrt + addf are needed for and2.1
I found about others -
loadrt mult2 count=3
addf mult2.2 servo-thread
loadrt comp count=1
addf comp.0 servo-thread

So can you walk me through getting the machine out of estop.
I have linuxcnc installed on a pc mounted in the machine connected to 7i97t, 7i74,7i84 and a 7i73. 3 heidenhain 602s wired to the 7i97t. just wired +10/-10 signals aswell and Im going through pnc config atmo, tring to figure out soft limit locations and directions for all axis.

Maybe you forgot the 'loadrt ...' and 'addf ...' lines for those components in your hal?

I decided to change the velocity it homes at from 1 to 0.1 and that made all the difference. It actually stopped and backed up the the home position. I am guessing that the little stutter I was witnessing was the motor attempting to reverse direction but failing causing it to continue to drift into the hard limit. I then tried that solution on the other axis but the knee decided to go all the way down to the hard stop so I need to figure out how to spin that screw back up off of it. Otherwise i think I have that all sorted. Just need to better figure out the PID tuning and whatnot. I pulled all the relavemt information from the machine constants of the old controller but I don't know if anything other than the max speeds will be relevant.

Yes I did! I am currently figuring out getting the machine to home properly. Should be getting the touchscreen for the control panel today so maybe I'll have time to work on the interface tomorrow.

v2.8.4

from what has been said here - 
forum.linuxcnc.org/38-general-linuxcnc-q...ue-with-g38-5#336766

I inserted the following lines into my hal -
#Negate Encoder Position
setp mult2.2.in0 -1.0
setp comp.0.in0 0.005 # Threshold value for encoder
net enable-probe <= motion.digital-out-03 => and2.1.in1

# Encoder position and comparator
net negated-encoder-out <= mult2.2.out
net negated-encoder-out comp.0.in1 # Connect to comparator input
net encoder-threshold-met <= comp.0.out => and2.1.in0

# AND logic to trigger only during probing motion
net probe-trigger and2.1.out motion.probe-input

when I start, I get an error -
parameter or pi 'mult2.2.in0' not found

from what has been said here - www.forum.linuxcnc.org/38-general-linuxc...dlock?start=0#332412

I inserted the following lines into my hal -
setp flipflop.0.set FALSE

net probereset motion.digital-out-00 => flipflop.0.reset
net probefiltered flipflop.0.out => motion.probe-input parport.0.pin-01-out

when I start, I get an error -

What am I doing wrong?

 

Meant to put this in the last post.  

I get that error if I change the feedrate for material 35 to 0.0.

Have them check the feed rate of that material. I imagine that's the problem.

Of course I am testing on QtPlasmaC, but I would posit it behaves the same.

There are 4 parts that seem misaligned, on the same left side only, and those have the error mirrored, so more probably to be something actually loose and moving on the machine, or bending that much ???.

Hey cooped-up.
Im at a similar stage of retrofit on an MH800w.
Following closely! did you manage to get the machine latched and out of E-stop?
Thanks Paul

What have you tried? Which Leadshine drive model?
I am going to propose to use PV mode. It is similar to a vfd.
You just give a speed and the driver ramps up and down as needed.
I have not tried it myself, and I don't have a driver to try it so it is up to you.
I foresee that the cia402 component needs modification, it only handles csp and csv.
