Help! Toolchanging broken (offsets + T-1)

Merlin246

Hello,

Suddenly my Toolchanger is not recognizing T-1 commands, and is not applying tool offsets.

I can home, and pickup a tool, the dashboard shows the tool as active, however once picked up the offsets have not applied (including Z-offset, rip my bed) and I cannot rehome the tool via T-1.

Running Duet 2 Wifi + DueX, firmware 3.4.5. It was working an hour ago, now nothing. I have tried restarting (via both E-stop and actual power cycling), the problem persists.

The only thing I've changed was the sensitivity of my stall detection in my homing files. Send help.

Sounds like maybe your config.g isn't getting read completely. Maybe you've added something accidentally that is breaking the parsing.

Can you share the full config.g and the results of sending M122 and M98 P"config.g" in the gcode console tab of DWC?

@Phaedrux

M98 P"config.g" output:
M98 P"config.g"
HTTP is enabled on port 80
FTP is disabled
TELNET is disabled
Error: in file macro line 96 column 20: meta command: variable 't1_ready_X' already exists

The same problems as described in OP persist

M112 Result
The printer e-stops, same problems persist

config.g
The config-override.g and config-tool-offsets.g have not changed (let alone been opened) in the time between the printer working fine and the problems beginning.

@Phaedrux a quick update, I commented out the T-1 at the beginning of my t0pre.g that I added in, and it is now working. I guess that is causing confusion in the printer, just added it in for safety and forgot about it. Problem solved!

M122 not M112.

@Merlin246 I'm glad you solved it. Nesting tool changes is never a good idea. Perhaps we should detect that in RRF and report an error.
