Can you post your hal/ini files?
 

Hi guys sorry to spam I've been told I need two of these opb866t55 but as cannot solder in need the wired equivalent could
anyone recommend from rs components link please?

It is not a following error.
The pop up says "operator error: joint 0 amplifier fault".
The terminal says
joint 0 amplifier fault
emc/task/taskintf.cc 976: Error on joint 0, command number 110

I never hooked up a way for the 7i97t to sense amplifier faults. The only input from the amplifier is the encoder.

Is the error an amplifier fault (something that would require a 7I97T input connection to sense)
or a joint following error? (cause by incorrect or lack of motion/feedback)

I try again and C turning in all direction.

Hi
the board is a 3-axis, but I don't think it depends on that, I think.
Ultimately, on six axes XYB working, Z and C turning in one direction, dir doesn't work, A doesn't work.
I haven't had any luck....
this is the second board, the first one in understanding how to flash it I must have made it unusable, I can't get it back.
I don't want to buy another one, never mind.
Thanks for the feedback
 

try this:pair the contents in this dir:
github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
download this: github.com/scottalford75/Remora-RT1052-c...xCNC/nvem-rt1052.txtpair your files:nvem-rt1052.hal,nvem-rt1052.ini
then: 
and try again please

I recently started working on finishing a plasma table retrofit that was put on hold for about 6 months.
It has servos, a hypertherm hsd 130 (I believe HF start), and a mesa 7i97t.

I thought I had it ready for a trial cut, but when the torch fired, I got an error.
error finishing read! iter=172124.
I tried again with the same result. I eventually realized that I had removed the torch start relay and diode, and instead hooked the torch start wires directly to the 7i97t. (Not for any good reason, I just kinda forgot what little I had figured out from 6 months ago and was hastily making wiring changes.)

Despite not making any changes after my 2 failed test cut attempts, I am having a new problem.
Now, after I start linuxcnc, when I hit the power button at the top of the plasmac screen, I immediately get joint 0 amplifier fault.
The DRO stays at 0 for all axis's when physically moved, but the amplifiers appear to be on and displaying encoder counts correctly on their little read outs.

I'm worried I damaged the 7i97t, but don't know where to go from here. Any advice is appreciated.

Hi guys just an update it should have 2 separate ones one counts the large slot and one counts a single slot. so two go one plug. still unsure what to buy something like this? but pre wired ones as my soldering ability

hi
thanks for the feedback,
for testing I downloaded again from the link you posted, I loaded the configuration file that is in the folder, the I/O seem not to be suitable for the NVEM, however dir/step are suitable,
my result does not change XY works, Z pressing forward and backward only turns in one direction, the dir channel does not work, and I think that by also setting the A axis it does not work.
I think it is a hardware problem.
thanks
 

Hi, I used your configuration by copying your files to mine and all the axes work. Did you get a board with only 3 axes? Or do you have a 6 axes? Because the manufacturer could have not soldered the bga. Or simply there is some faulty circuit, I don't know if there are opto-isolators in the output but there should be.
but I didn't compile any hal file like this  "nvem-rt1052.hal"
