Config file with TAP. HELP!

[7milesup]

Background...  I'm a total beginner when it comes to configuration files because this is my first 3D printer build (other than a Prusa 2.5s that I "built").  

I am going nuts trying to figure out a z_offset issue when trying to update Klipper.  Here is what the ERROR states...  (sorry, I was going to do a screenshot but can't figure out how to do that either in a Linux ecosystem).

 

Option 'z_offset' in section 'probe' must be specified

Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted

I followed the "Updating your Klipper config for Tap" instructions from Github BUT, I have no idea where or how the "PROBE_CALIBRATE" line is used.  

There are no values at the end of my config file because this error, and others that I have encountered, will not let the printer run.  I have attached my config file, which probably has a bunch of errors in it. 

Build is Voron 2.4r with Phaetus Rapido and TAP as the only non standard mods from the Formbot kit.

Help would be greatly appreciated.

You are correct that mine just has the Print_start in start of g-code under machine settings.  So the "[=first_layer_bed_temperature] is telling the printer to look at the g-code produced by the slicer and set the bed and extruder temp to those first layer settings? 

In your second post, would all of that be in the Cura machine settings, thus expanding on your previous basic settings of bed and extruder temps?

The only thing that goes in cura GCode settings is this line:

START_PRINT BED_TEMP=[first_layer_bed_temperature] EXTRUDER_TEMP=[first_layer_temperature]

[mvdveer]

Then in your printer.cfg file - look for the [gcode macro START_PRINT]

Deleted this

Copy the following and paste that into your printer.cfg file

[gcode_macro START_PRINT]
gcode:
    #G32                            ; home all axes

Now before you start to print anything make sure to calibrate your probe first, if not already done. We don't want scratches on that brand new PEI plate How do I know this - Experience and a couple of ruined plates

PROBE_CALIBRATE

[7milesup]

Now this error....

 

DRV_STATUS: 800f00e0 s2vsb=1(LowSideShort_B!) ola=1(OpenLoad_A!) olb=1(OpenLoad_B!) cs_actual=15 stst=1

Looks like a possible wiring issue?  I have the two piece Hartk PCB tool head.  I will review the wiring.

Did you test the extruder seperately to the motors? This is most likely a cross over in the wires.(Been there, done that) . Could also be the hold_current in the TMC section

If X homes, Y home and Z homes, and you can sucessfully do a QGL, then it means their drivers are A-OK. The only one left is the extruder.

Heat the toolhead to 200 for PLA.

Issue the following command:

G1 E50 F60  - extrude 50mm of filament slowly

If you get the same error, we know it is a cross over of the extruder motor wires.

Gotta think which two wires we have to swap.

Looks like a wire issue.  I get the same error when trying your G-code command.  I am going to go grab my ohm meter to verify which wire is which for the coils.  standby

Sensible thing to do - unlike me that would just start swapping wires .

[7milesup]

It's printing!!! 

The error came from the Extruder wiring harness on the Octopus board.  For some reason I had two wires switched around.  Now I need to do the fine tuning.  I also need to look at the LED commands because at the moment I have no light on the toolhead. 

Thank you guys sooooooo much.  What a ride.  I have learned so much in the last few days.  I have a friend and coworker that is building the same exact one that I have, so hopefully I can help him out when his Voron is finished and pass it forward.

Don't get too comfortable though, I am sure that there will be more questions coming from me tomorrow.

Good starting point is the Ellis tuning guide - the gold standard for excellence in printing

First step again is wiring and making sure you have the LEDs connected to 5V and the board pins are defined correctly.

Looking through your printer.cfg file it seems the LEDs have not been defined. See here for further info.

Happy to run you through this when needed.

Roger that @mvdveer!  I will pick this up tomorrow evening again.
