Thought others would like to see the latest video from Stefan @ CNC Kitchen.

@milesthomas I’d say look at a Prusa for ease of use.

@arnold_r_clark fair point I have boxes of various printer (spares), just in case.....

@bot I’ve added the T0 to config.g as suggested above. Using reprap FW in settings. First few test prints look good to be fair. A benchy looked better than from Cura

Give Prusaslicer a go. I’ve moved to it from Cura and I’m impressed with it

@TF_Sinthoras You can use the retraction tab here to tune it.

@Sindarius Thanks! Something new I've learnt today.

@fcwilt

Ah, gotcha. That makes sense now. Thank you. You guys have been super helpful. I just closed about 30 tabs since those questions have been solved for me. haha

I am now trying to see if I can get the probe to work. I am googling how to change the mesh grid(?) when it probes. I noticed when it first tried to probe it wasn't quite on the bed. I am assuming its coordinates on the m557 line. Still searching. The other thing I have to find is why it doesn't deploy the probe when it starts homing. It is lit up, it will kick in and out when I turn the printer on. But I need to find what I change to make it deploy when it goes to home.

Do you have a deploy probe and retract probe script? M401 should deploy it and M402 retract. I was in a very similar position to you just the other week so this is all very fresh and familiar for me!

Interesting videos. New gear design required. I had the thought of using two motors to drive in unison but that comes with it's own issues.

@bearer Thanks. I'm making some progress now with this approach. testing my dexterity for sure

@droftarts No, I found that setting. Now I think about it though I had already downloaded the file so changing it afterwards makes no sense. I needed to download the file again..... Sometimes looking at things with fresh eyes help! thanks

@jay_s_uk Sorry, I kinda did a thread hijack. I was trying to update via DWC. I was on a 3.4.1rc and wanted to update to 3.4.2

It was just incredibly frustrating yesterday trying to get it to work.

I tried updating my Duet yesterday using my Mac but couldn't simply because when I tried to upload the firmware instead of uploading the zip it automatically extracts it and shows the file contents. I couldn't figure out how to resolve it.

In the end I had to use my work laptop (Windows). Would love to know how to use the Mac for this.

@zapta Is he buying the boards himself or are they provided FOC. The pain isn't the same when someone gives you these things.

I Got one .
It is fast.
Also very close to experince like geting HP laser jet and runing it. Espesialy with PLA.
This thing will take away the good sleep of Prusa, ultimaker, Raise 3d etc

I got mine last week, Have to agree. Only going to get better as well.

@asdfasdf426

These are my old 280 files. Maybe a better starting point.

Printer Profile

Explains how to setup a new printer profile, also where to save/edit the files.
https://github.com/Ultimaker/Cura/wiki/Definition-Files-Explained

Created by GH (15/5/19)

Updated version (20/05/2019) NOTE: May need to switch the left and right extruders in the definitions to match Cura. Currently Material 1 prints on the right extruder, I think logically you'd want it on the left and Material 2 on the right?

If you want a representation of the build plate (helps with positioning). Then save this to the meshes folder

Material I created (PLA)

In addition I wanted to find a way to have Cura save out the gcode files with the ebp extension. Using this link I was able to find a way….

https://github.com/Ultimaker/Cura/issues/1059

Save the file below to this location.
C:\Program Files\Ultimaker Cura 4.0\plugins\GCodeWriter

Copyright (c) 2015 Ultimaker B.V.

Cura is released under the terms of the LGPLv3 or higher.

from . import GCodeWriter

from UM.i18n import i18nCatalog
catalog = i18nCatalog("cura")

def getMetaData():
return {

    "mesh_writer": {
        "output": [{
            "extension": "ebp",
            "description": catalog.i18nc("@item:inlistbox", "G-code File"),
            "mime_type": "text/x-gcode",
            "mode": GCodeWriter.GCodeWriter.OutputMode.TextMode
        }]
    }
}

def register(app):
return { "mesh_writer": GCodeWriter.GCodeWriter() }

The next thing I'd like to figure out is how to edit or stop Cura adding text to the start of the output file. This needed to be deleted before you can print.

Example: Yellow text need deleting or a way of having the ebp@280 line first (I think the printer FW looks for this to authenticate the file is suitable for the printer).

@asdfasdf426 said in ST3Di Modelsmart 280 - Duet Maestro repair/upgrade:

@blacksheep99 Hi I think I may be having a small problem when I load gcode (from cura) onto a Micro SD card and put it in the printer the printer says no models found. To set up cura I just copied and pasted the start and gcode from your ST3Di_Modelsmart_200.def.json.zip file. Was this the right way to that or have I done it wrong. Or do you know if this may be another Issue.
Additionally, do you know what I should put for the X and Y offsets for the nozzles because I don't really know what they are and how to find them out. (I just measured the distance between the nozzles with a vernier callipers and but that as the X offset Which I'm sure is not the right way, Do you possibly know how to do it and/or have the offsets?) Thanks for all your help so far.

Hi, I'm struggling to remember if I'm honest. I'll check for old configs for the 280 as the ones in the zip are for the 200 (principle is the same). Did you save those files to the folders as per the guide?

For the 280 I think you need 2 extruder files and they should be referenced in the definition file.

I don't recall needing to change the offset of the two extruders as I think they FW controls it. You may be able to use Cura to tweak it though if they are slightly out.

let me know if this works.

@asdfasdf426 Hi, send me a DM with your email. I'll send you the word doc. I hoped you could right click the links here and save as?

@danwilliams94

Hopefully this word doc has the config files in. The principles should still be true.

I'd move to Cura or Prusaslicer rather than use the old ST3DI slicer if you can.

The pla@**** is what is telling the printer how much filament you have used from their spools.
