You can remove the resistor networks and install them in backwards
to have pulldowns rather than pullups. I would not simply remove them.

If you do this you should also disable pre-config pullups (W3 down)

Note that you should not do this for Mesa daughtercards that are active low

Is that a CoreXY machine?
If not, remove that line in the ini file and use the line above it.

See if this helps

Ok just checked and not much there, so
How are you loading the file and from what?
If from network or USB, try copying to HDD and load from there.

7i80hd pullups are removable can remove them to do outputs active high ?
What about internal pullups must disable them also ?

 And when I do get it to load I allways get this notification. Everything still sends to cut ok but maybe it’s time for me to face my fears and just update. 

What is causing this error when I load my Gcode file. It only seams happen when I load a file with a large amount of parts. Some times I can close the notification and reload but today I couldn’t and even closing linuxcnc did not remove it. I had to restart the computer to remove it but it when I loaded the Gcode it showed up agian. The sheet only has 32 parts in it so not overly large. I’m running a plasmaC version at least a few years old as it just works for me and I could not afford the risk of trying yo update and break something.  Thank you, I’m hope it’s just a setting somewhere where I can increase the timeout duration. 

Oh. Forgot to mention. I got a 12mm ballscrew for the cross slide. Hoping it is small enough to make it work.

I was a bit busy with other work, so I didn't respond to your answers earlier.
The barcode has 2 series of numbers with 5 characters x+y, I can do that in the plc controller, but only the positioning is the hardest part for me, that's why I thought that maybe there is a solution, for example in linuxcnc, which is much better for positioning.

jtrantow - Good to hear from someone with the same hardware to convert. I think what I will try first is a slotted disk with as many slots as I can reasonably fit on it with one deeper slot and 2 optical slot detectors. It may wind up less slots than you have and since I would only have one detector reading them, I will have less counts per rev but will see how it goes. I like the idea of the slot detectors because they don't have any moving mechanical parts like a rotary encoder. It should also be less involved to implement than a rotary with the sprockets, belts, brackets etc. Maybe I'll wind up with a rotary but I'm going to give this a try.

Thanks Again.

Thanks for the reply PCW. I guess I will go with a system that has an index and also at least some number of pulses per rev on an additional channel.

Originally all 50 pin FPGA cards were made to be pinout/functionally compatible with OPTO22
relay modules. These are all active low. Some 50 pin cards have plug-in pullup resistors that
you can reverse to change from pullups to pulldowns.

Its also a side effect of Xilinx FPGA characteristics where you can define pre-configuration
pullups but not pre-configuration pulldowns.
 

The ping times look OK but 6000 is not really enough (60000 is one minute
and a more reliable indicator of timing issues)

Note that 184004924 hm2_7i96s.0.read.tmax means about
6ms delay (at a 3 GHz CPU clock) which is why you would
get a watchdog bite.

What host Ethernet chip do you have?

lspci | grep -i eth

Should show this

Have you run a latency test on the PC?

Another question..
Why mesa fpga cards have pullup resistors ?
If i have breakout board with relays that the inputs are active high
when linuxcnc is closed mesa fpga outputs +5v to output pins
and it enables breakout board relays which is unwanted behavior.
Why not have pulldown resistors ?
For inputs this is not a problem because i can read gpio.000.in_not
also for outputs can do gpio.010.invert_output true
but this is when linuxcnc runs when fpga card is powered without
connected with linuxcnc what can i do ?

I am using byte2bot, and my XY axes are based on a CoreXY system.Right now, I’m trying to use homing, but when I enter the system, I can only use the XY axis after the joints are homed. However, I am unable to home both joints at the same time.Is there a way to skip joint homing and directly enter the XY system, then perform homing from there?
Like the attached picture.
