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

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

I inserted the following lines into my hal -
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
net probefiltered flipflop.0.out => motion.probe-input parport.0.pin-01-out

when I start, I get an error -

parameter or pi 'flipflop.0.set' not found

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.

I just migrated from Mach4 and Pokeys57cnc, and was hoping to keep Postep60-256 drives in my new setup. I wired postep drive to Mesa 7i96s as follows: Postep pins 1/2/3/5, 2 to TB1 pin1 (GND) / 3 to TB1 pin5 (DIR+) / 5 to TB1 pin3 (STEP+) and 1(enable) to TB3 pin13 (OUT-).
I have been at it for about a week now, I can’t figure out what I am doing wrong. Using Pncconf wizard, the home/limit/ estop are working but the drives are not getting enabled and the stepper motors are not getting any pulse.
any help would be greatly appreciated, thank you in advance!
ps! I am very new to Linuxcnc, migrating from Mach for almost 2 decades.

Well I had that set to 0 so I figured it would stay at 0 but perhaps I should make it set to be further in the other direction

I log data the following way, LOGAPPEND extends the file, while LOGOPEN overwrites with new content
 

Thank you, I'll try

backlash should be seen an all part,
first i would try to repeat it with very slow feed rates
