Basic Information:

Printer Model: TEVO Tornado

Host / SBC - RPI

Describe your issue:

Starting from scratch on this printer, I have it printing properly, but I think I messed up my macros. I was taking suggestions from too many different places and I think I really messed things up.

Here’s my rundown.
Tevo Tornado - Printer specs in the config are good (feel free to take a look and suggest if you see something out of the ordinary)

Using a Filament sensor (switch style)
Klipperscreen
Slicer - Simplify3d
(Let me know if there are other specifics needed)

Here’s my printer.cfg. Please review my macros, let me know what needs to be fixed, removed, added.

I totally confused myself and now I can’t make heads or tails of what I need and how to format for my setup.

I really appreciate this! I have been struggling for days trying to make sense of everything.

One short questiion?

What’s the deal with always deleting this section?

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

sorry about that. New to all of this and just learning the cadence. I’ll know for next time.

It’s ok. Just wanted to say that the printer.cfg usually appears in the klippy.log.

So, the config looks legit.

Some errors explain themself.

gcode.CommandError: Must home axis first: 134.220 111.780 26.510 [24016.562]

Maybe you tried to move the printhead before homing (G28).

There are some macros that include the M84 command.

This turns off all motors and Klipper is in an undefined state and has to be homed again.

You may need it in END_PRINT and CANCEL_PRINT but it is questionable if it’s use is required in the other macros.

what sent me down the rabbit hole was a 16 hour print that ran out of filament.

The run-out sensor did it’s thing, however, when I went to reload the filament and resume the print, Klipper wouldn’t resume till I re-homed.

Well, there was no way I could re-home because my print was on the bed right where Z would home.

I have been racking my brain trying to figure it out.

Then as I was reading, I saw how others changed their macros “for the better” and now I am completely messed up.

So, I think I need to start from scratch and re-do all the macros properly.

Just trying to figure out what a “proper” macro is and which ones do I actually need.
