@chrishamm Thank you for your response.
I will adapt the T parameter of M669 and see how it works.

@Macwolf you measured that with the bed still installed on the frame, right?

Please try to adjusting the back right corner of the frame right Y rail) by .1mm upwards and remeasure.

@dindo59 if it's that far you then you have a wiring error and you are feeding 5V to the 3.3V rail. Correct your wiring before you cause permanent damage. If it's a Duet 2 then this is typically because the PanelDue ribbon cable is plugged into the wrong socket.

@dindo59 i doubt B4138 is the correct for a CR10. they should be B4092.

When do you see the temperature oscillation? If its during heating, have you PID tuned the bed and hotend?

@dc42 Hi

Sorry I was with vacation.

Could you please specify what you mean with the macro's?? and the S parameter?

Hope to hear from you.

@dmtulsa You don't say exactly what you doing that won't control the hot end. Is it the controls in DWC? Make sure you are running the same version of DWC as RepRapFirmware, ie DWC v3.4.5. It could be that you are running an old version, where heater control is different.

Your thermistor settings (M308) are using the default thermistor. This is unlikely to be correct. Do you know what thermistors you are using?

It may be better to tune your extruder heater as a tool, rather than the heater itself. Rather than using M303 H1 ... , use M303 T0 ... to tune the tool. See https://docs.duet3d.com/en/How_to_guides/Commissioning#h-7-tune-heaters

If that doesn't help, power off then power on the board, then send M98 P"config.g" to check there are no errors in your config. Send M307 H1 to check that the correct PID values are being used. Post any output if it is not what is expected. Post your full config.g, as you may have errors in the tool configuration that is stopping the heater working.

@Phaedrux Yes I tested the outer pins on both of those connectors and they were both 47.1K Ohms. But I think I found the issue, when removing the X plug from the board, one wire pulled out of the connector but the pin remained in the connector. The wire was broken clean, I removed the pin and found a good crimp, it just broke off right through the insulation and the wire. Makes me wonder if these original Creality wires are at all trustworthy now, might purge these old wires from my setup. And on a good note, I was finally able to print an XYZ block!

@MIke-1
This here at the very end fixted the issue!

Thanks to the Duet Team!

@OwenD I'm on 3.4.5, so not sure if the bug is exclusive to b3, or if it goes farther back. I can try manually entering M701 S"filament" M703, and see what it does.

@Surgikill said in Filament unload.g waiting for temperature to drop:

On line 26 I see that you have global.LoadedFilament. I'm assuming you are assigning this variable somewhere in your load.g for the filament that you load, correct?

FYI this is my slicer start gcode
Without it some of the other macros may not make sense.

@dc42
Thank you

@selva_tvi I think the problem is that you are trying to send tool 1 below Z0. The left tool, which I assume is Tool 0, has G10 P0 Z0. When applying offsets:

Tool offsets are given as the offset of the nozzle relative to the print head reference point, so the signs are opposite to what you might expect because tool offsets are subtracted from the required printing locations during printing.

You are using Tool 0 nozzle tip as your 'print head reference point', with Z0 at the tip, but you need to go -0.3 below this for Tool1, which takes it below Z0. I think there are a couple of options:

Set M208 to allow for some negative Z movement, or Set Tool 0 to G10 P0 Z-0.3, and adjust the Z probe trigger height/homing height, and set Tool 1 to G10 P1 Z0

See also https://docs.duet3d.com/User_manual/Tuning/Defining_tool_and_Z_probe_offsets for a better explanation of using tool offsets.

Realistically if you are printing in duplicate and mirror mode, you will achieve better results by getting both nozzle to the same height.

@jens55 I'm glad you found a solution. 240C does sound rather high for PETG. I use 225C.

@LuniLAB said in Position after tool changing.:

otherwise it prints midair. Is there any solution to make tool change work the way that next extruder doesnt move to the previous extruded location?

Unfortunately there isn't at present. The fact that it prints in midair when you don't give it the commands to resume position in the tool change file means that your slicer isn't commanding it to go to the correct XYZ coordinates for the start of the next move.

To solve this would require RRF to ignore any travel moves after the tool change command, then when an extruding move is seen, generate a travel move with all coordinates specified. This is a little complicated, however we already do something similar when skipping objects, so I will take a look at it when I can.

Issue https://github.com/Duet3D/RepRapFirmware/issues/807 refers.

@Gubbfittan said in Flashforge creator pro ---> Duet 2 wifi:

Anyhow,the printer only have one motor for Z and a BLTouch.
So i think the guide you refer to does not apply ?

If you only have a single motor you could do the manual leveling assistant which would tell you how much to adjust your bed screws to get it level. And/or use the mesh compensation to map out the surface of the bed and adjust on the fly during a print.
