Stepper Z2
Hi, after my old Octopus card burned out, I bought an Octopus with an H723 v1.1 processor. However, after installation, I encountered problems with the Z-axis and the Z2 stepper driver. Can someone explain or help me fix it?
TMC 'stepper_z2' reports error: DRV_STATUS: 00130054 s2ga=1(ShortToGND_A!) s2vsa=1(ShortToSupply_A!) ola=1(OpenLoad_A!) cs_actual=19

Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.

It is saying you have a short in your wiring or driver
I have tried connecting the motors in the place where the extruder is located, and they work fine. I followed the instructions in the manual.
What driver is Z2? Should I replace all the drivers and the extruder, or just the 5 drivers? What do you think?
Each stepper driver works fine in the place for the extruder's stepper driver.
sounds like your cfg is not calling up the proper board. Which 'include' statement' did you enable in printer.cfg?
After my Octopus Pro v1.1 branch, I purchased the Octopus Pro H723 v1.1, which was not listed in the printer.cfg file, only the regular version H723. However, everything else is present in the RATOS/Board folder with the name btt-octopus-pro-h723-11. So, I changed the include to the same name.
default h723 only
Sometimes the axes move, but the Y-axis does not respond to the Y-endstop. The Z-axis moves slightly, sometimes all the motors move, and sometimes only the right one moves.
sounds like you'll need to go in and check all the default pin assignments for the board. There should be a file that you will need to edit to make the pin assignments match the board documentation. you'll probably need to copy that (highlighted in your post) file to the same dir. as the printer.cfg, edit it, and include that vs the highlighted file.
hhhmmm... I just took a look at and tried to compare
config/RatOS/boards/btt-octopus-pro-h723/config.cfg and
/config/RatOS/boards/btt-octopus-pro-h723-11 /config.cfg and can't say I see any difference in the two cfg files.
That leads me to believe you have a pin or two in a connector somewhere that is not making contact the way you think it is/should be.
worst case...try reflashing the new board
There is a difference in pins. If we compare both files.
For some reason I didn't understand, I initially flashed it with a file for the h723 version, but the heater did not work, the motors worked fine. When I noticed this and corrected it, it became the opposite. The heater works, but the motors do not.
I can't understand what the problem is. I flashed the regular h723 firmware version, and it worked fine for 3-4 times, but then it stopped working. Sometimes I can park the x, y, and z axes separately, but suddenly the same issue arises with the z2 driver. Additionally, the extruder heater is not functioning on this software version.
Has this board ever flashed/worked properly? Perhaps it's simply defective (bad processor chip?) or some other abnormality here.
Its 100% h723 v 1.1
might have to ask @miklschmidt what variation if any exists between rev 1 and 1.1 if there is any.
for octopus - just the silkscreening. the 1.0 had the silkscreen wrong, so they fixed it and called it 1.1. That's why you don't see different documentation for 1.0 vs 1.1
I have checked and switched all the connections on the motors, flashed firmware version 1.1, and now it
