I also tried setting the G10 offset in between prints using the same Gcode, and I see no Y-offset being applied at all. When I apply the offset and move the printhead to the same position (for example X100 Y100) I do see the difference in Y, yet in the print itself it doesn't seem to work.

I am using RRF 3.2.2.
I got a -sorta- fix. Apparently the offset of the second nozzle isn't applied, yet when I apply it to the first nozzle it seems to work. Maybe this would need more investigation why the y-offset is only applied on the first nozzle and not the second.

And some pictures for reference that I am very happy with my results thus far! (except the tiny Y-offset)

Hi all,
With previous posts getting my UltiDuet (Ultimaker 2 + Duet + Dual nozzle) to work I am now in the final steps of calibration. I seem to have the X and Z offset of my second nozzle calibrated, yet the Y-offset seemns a little off still. In my slicer I have just the same filse sliced and I do tweaks on my config.g file to set the offsets.

The weird thing is that no matter how much I change the Y-offset my print doesnt seem to line up perfectly, yet the tool change macro I use (to change the nozzle) no longer lines up to its too change position, so some form of offset is being applied, yet not on the print itself.

This is my config.g:

For tool 0 I dont have any offset, and just for Tool 1 the actual nozzle position changes:

Flashing the correct firmware this time (>3.3.1) has resolved the issue. Thanks for all the information!

I changed to DFF v3 and changed the needed config lines to make my printer operational again.
Running "echo move.axes[0].machinePosition" in the console I still get the following:

Also changing the macro to the code that @T3P3Tony mentioned also didn't seem to work.

Currently I am using RepRapFirmware for Duet 2 WiFi/Ethernet 2.03 (2019-06-13b2). Beginner's mistake here i guess to assume I used 3.2.2 (but it was only the Duet WEb Control 3.2.2)...

@T3P3Tony sending that command trhough the console gives me back the same "Bad command" message.

I tried, yet I still get the error and lines 2 and 3 are executed even when X<195

Hi all,
I'm trying to get a conditional move command into a tool change macro, as with X being over 195 it will crash the lever into the actual tool change tab (ultimaker 3 style).

For this I have the following command, yet whatever I try I cannot seems to get it right (as I keep getting a "Bad command" message

Thank you! That seemed to do the trick.
