Attempting to extrude with no tool selected.

Gamefanatic3D

Trying to get some bugs worked out of the Tool Changer system. Right now I have a single tool defined in the system. I was running into random pauses in the prints that I am now troubleshooting.

I created the following Gcode (TC-Baiscs):

T-1
G28 ; home all axes

When running the file the first time I startup the system there are no problems. However subsequent times the following errors will occur and pause before the G28 command completes:

M24
Error: Attempting to extrude with no tool selected.

Or sometimes:

Error: Invalid tool number

Post your config.g, homeall.g (and any other homing files and macros called) your tool change files. And post the results of sending M122 and M98 P"config.g" so we can see what's actually happening.

You've got some problems in your config.g to sort out.

Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset.

Remove the M375 at the end of config.g. You should only load the heightmap after you've defined Z0 by probing.

These are just warnings about what your max temps could be in a runaway condition.

Gamefanatic3D

Okay. I changed some of the things in the config.g, but the change I made to homeall.g appears to have resolved the problem. Apparently somewhere along the line homing the tool coupler axis was removed from the scene. Odd as it would do it with a G28 or clicking the home all button.

I wasn't sure where the best place to move the M375 command. But I placed it in the movez.g so it executes after a Z homing.

Okay. I remember removing it from the homeall.g on purpose as I can't check to see if my tool is loaded upon startup without being able to check for the existence of my tactive.g file. My understanding is this ability to check for a file existence within the system will be coming in a future firmware update...

I'm just going to have to be cautious. This is why I tell the system to unload the tools at the end of prints. Some tools are going to be taller than my probe and it could be quite disastrous if I can't be sure how the system responds.

Gamefanatic3D

Well, I jumped too soon. Still having the problem. It's not consistent but does happen more so after a print. I have had it happen just after a restart as well.

I'm going to keep messing around to see if I can get some consistency...

Phaedrux

It's still not clear to me when and where those errors are being thrown.

Gamefanatic3D

I can understand the confusion as it's a head scratcher for me.

I still need more testing, but so far this appears to only happen when running a Job.

It appears to occur when I run G28.

TC-Basics.gcode

T-1
G28 ; home all axes

and I will get different results. I would expect if it was related to a short, there be some indication of what the system was detecting.

If I run G28 from the web console it executes, so far every time.

Only seems bomb when I run it within a Job.

Here is the output from the console when I run those two lines of code within a job:

@Gamefanatic3D said in Attempting to extrude with no tool selected.:

; Home C (Tool Coupler) M98 P"homec.g"

What's in homec? And how bout your tool change files?

Can you also post the first 50 lines or so of a sliced gcode file so we can see what it's doing during a job?

Gamefanatic3D

Homec is for the E3D Tool Changer motor.
