Okay, cool. Let us know if you try it out. Maybe you could check if its the same for you as for me when trying to jog while running gcode prior to updating the xhc-whb04b-6 component. The pendant always disconnects in that situation for me.

Yes, i have noticed that, hence my question, but i think you should be clear from now on, based on what i gather this happens when there is a single post from a member in a certain timeframe and might be due to automation set to disable spammer accounts.

_usually_ CR343 will protect the rest of the card from overvoltages

CR43 is (or was) a SMBJ5V0 TVS diode across the 5V supply
 

You need to install a user configuration (the fallback configuration has no modules except GPIO):

mesaflash --device 7i95t --addr 192.168.1.121 --write  7i95t_d.bin 

(7i95t_d.bin  is from the 7i95t.zip file in configs/hostmot2)

Once this is done, you can set the IP select jumpers to DOWN,DOWN (192.168.1.121)
or DOWN,UP (10.10.10.10)
 

I remember you mention something about the dpll?

I was trying to create a machine to test the borad

The computer screen, with the g-code trace. 
I have some user macro buttons, they are on the screen in Man but are removed in Auto and the trace window is resized.
I agree with the too long blocking diagnose, sounds exactly like the problem.
I'll try that tomorrow, it would be great to get a fix.

Do you means when the computer screen re-organizes? Or the pendant screen?

I found that if I try to jog when a g-code program is running, the pendant will disconnect every time. The reason is too long blocking (like I mentioned in the first post) without USB polling. The pendant will request manual/teleop mode (I don't recall which) and wait for minimum 300 ms if the mode does not change. It's these two functions:
github.com/LinuxCNC/linuxcnc/blob/master...6/hal.cc#L1361-L1420
I solved this issue by reducing the "loops" parameters here:
github.com/LinuxCNC/linuxcnc/blob/master...b04b-6/hal.h#L71-L86
Maybe your issue could be because of the same reason?

Still, if I use the mill for an hour or so, the pendant is likely to disconnect. And I have not found any specific reason for that yet.

There it is.

 

The problem is with your slave 5, the EL1014.
Can it be that it is a very old version? They had a different PDO mapping.

Can you temporarily remove or comment out slave idx=5 and see if you 
come any further?
We can come back to how to fix it for the EL1014.
Well, it is to run lcec_configgen with the option, "lcec_configgen --typedb=false"
and then take the info for slave 5 from that output.

that's awesome great progress.

quick question

have you caught up with Rob from tormach yet about including any of their work from the 1500mx machines

Hi everyone,

I just started my first LinuxCNC project and unfortunately managed to damage my Mesa 7i96S right away. I accidentally applied about 10 V to the 5 V input for a few seconds. There was a little smoke, and now the board draws about 3 A at 5 V even with no external load connected.

Using a thermal camera, I identified a hot SMD component marked “KE 2E66B” located very close to the 5 V input connector (designator CR43 on the PCB). It heats up immediately when power is applied. Measuring across it shows about 0.6 ohm. From the package and marking it looks like it could be a polarized SMD capacitor (possibly tantalum), but I can’t determine the value or rating.

Can anyone tell me the specifications of this component, or point me to the correct replacement part? Is there a BOM or schematic available that lists its value?

Thanks a lot for your help.

Hello,

I have made the decision to try LinuxCNC for my plasma machine that has been running with Mach3 so far.

Thebplan is to use EtherCAT servos for the motion of the machine. I installed LinuxCNC from the official site Downloads section, the latest stable version - 2.9.8. Then followed MrRodW's video about installing the EtherCAT master and CiA402. This is the -  Video .

The computer I try to run LinuxCNC EtherCAT is a mini conputer a few years old with an HDD of 1TB.

The problem is that when I reched the step that requires using the halcompile command, it executes without any error but there is no cia402 folder in /linuxcnc/configs. Without having the folder, I cannot continue the procedure for CiA40w installation.

What could be the reason that prevents creation of the cia402 folder?

Best Regards
Konstantin Kolev

Beautiful!

You are hands down a genius

Do I still need to flash the fallback.bin and the .bin file?
if so, how can I point mesaflash to these files?

If UP.UP works, stay with that

Then setup you hosts Ethernet interface to a static IP address of say 192.168.1.100

(the current settings will not allow access to the card)

I guess I never tried access to 192.168.1.121?
I have always used 10.10.10.11
