I downloaded DO firmware from the firmware download tool using these settings
Machine -TAZ Pro
Board - Standard
Probe Style - Standard
Toolhead - Dual extruder
Display - Standard
Media - Standard
Runout Detection - Standard
I downloaded file:
Marlin_Quiver_TAZPro_Quiver_DualExtruder_2.0.0.1_fcc869d20d
I did the firmware upload with the ‘upgrade eeprom settings’ option.
I then reset the printer to factory defaults in the touchscreen.
TO be sure I repeated flashing and restore to defaults
The 5-30sec hoppping of Extruder #1 does not occur.
I set the extruder steps/mm to 423 as I earlier measured this.
I issued M420 S0 in the gecode terminal (octoprint)
I then proceeded via the touchscreen to do
-backlash automatic measurement
-autohome
-nozzle offset calibration automatic measurement
-save settings
-autohome
-cooldown (extruders are not turned off after calibration)
-manually
When the printer performs a nozzle offset calibration, it does 3 measurements on extruder 1 and the measuring cube. It does only 2 measurements using extruder 2. Just like the original firmware does.
Following happens (both in original and DO firmware):
-measure extruder 1 fast
-change extruder
-measure extruder 2 fast
-change extruder
-measure extruder 1 slower
-change extruder
(no measurement!!!)
-change extruder
-measure extruder 1 superslow
-change extruder
-measure extruder 2 superslow
-report measurement complete
Same happens when doing backlash auto calibrate (which seems to incorporate nozzle offset measurement if I’m correct).
I was distracted for a while and then the hopping of extruder 1 started.
But now it occurs much less frequent than before…
Then I did M420 S0
Then I did G28

The I wanted to adjust the Z Offset using the ‘Advanced settings > Probe Z Offset’ option in the display menu.
It reads -1.10 in the display.
I coose ‘Z probe wizard’.
The toolhead moves to approximately X=140 and stops.
The display messages about being able to slip a piece of paper between bed and nozzle.
If you press ‘Okay’ (only option on the screen) you come back to the Z offset menu but
the wizard is grayed out.
Printer is stuck.
In the Gcode terminal following is displayed. (I gave an M119 to check endstops)

Printer now needs hard reset.
After hard reset, I select auto home. Toolhead homes.
Then I select Probe Z offset. Toolhead moves to middle of bed and buries itself there.
Offset is the default -1.10mm
Message is displayed about paper between toolhead and bed.
After Okay-ing this message I can manually move the toolhead using the buttons in
the Z Offset menu.
At -0.20 the piece of paper slightly drags between nozzle and bed.
Paper can be inserted and removed while slight drag is felt.
I leave the menu via the back button and leave the advanced settings menu.
A window pops to ask i want to save current settings. I press Yes.
Then I go back to Probe Z offset and -0.20 is shown as value.
I autohome the toolhead
Then I loaded filament and printed the vernier which is included on the Lulzbot USB stick
Especially when the toolhead is making tiny movements like bed levelling
before printing, Extruder #1 jumps very often and in rapid succession.
The print (same gcode as with original firmware) fails.
I tried both the original code and the code optimized by ArcWelder.
Original firmware did flawlessly.
Both codes go wrong after the initial G29 (bed levelling).
After probing washer 4 (left rear if seen from the front)
toolhead moves X axis to middle of bed, Bed stays all the way forward (Y=292).
Screen reports both X and Y in the middle of the bed.
Extruders puke all over the Y axis belt behind the build platform.
In the original firmware, after G29, the same gcode moves head to Y=negative, X= middle of bed.
THen both extruders get primed and wiped on the edge of the bed.
Then the toolhead moves to the middle of the bed, draws 2 large perimeters with both extruders.
The starts printing the vernier.
