OK Figured it out....FINALLY!!

Just so you know, the motors are louder than the creality stock board. I plan on replacing them, once I have found a "better" version of stepper motors that are more compatible with the Duet 2 Maestro board. (Anyone have any suggestions? What's the best on the market?)

The stepper motor for the Z axis needs to be set to 800, not 400 steps. It seems the stock motors of Ender 3 and 5 Pro are different. The lead screw is "TR4" with a 4mm pitch and set to 1:1 ratio. You can then set whatever microstepping you want. 16 works fine for me.

Also, make sure you set your extruder to run 'Backwards' not forwards (another difference between Ender 3 and 5).

If you want higher resolution you can set your extruder to 128(on) microstepping. Whatever you choose, make sure that you set your "Hob Diameter" in the reprap config tool to 10.9 and 1:1 gear. That will set the calculation to the correct value.

The rest of the settings that you see below are directly from the Marlin board, so I am sure they are right and I'm getting some decent prints now. Louder, mind you! At this point, I don't mind.

To be honest, I am still not convinced I have the right settings for the motor currents. I couldn't find any conclusive info on this. I will do some more digging and update if I find anything.

Attached is my config file.

Bear in mind that I added an additional 5015 blower to my filament blower. Thus the tool to make sure they are running in-sync.

***Pro tip: if you have a brand new board, it seems they ship the jumper for the "FAN2" to 5V. Make sure you change it to "VIN".

I also have a Hero Me Gen3 cooling duct attached, thus the offsets, Mesh grids, etc. If you plan to copy-paste, make sure you calibrate these to your machine.

I also google and found the correct settings for the heaters of the hotend and bed. the ones here are safe to use. I have not done a PID tunning yet though...never done before, will try that to see if it works out for me.

It took me a while to find all of this in various places on the internet.

Hopefully, this starts you off well.

Happy Printing!

I just updated to latest firmware on my Duet 2 Maestro (3.1.1). I also purchased a NPN NO proximity sensor, but having a hard time understanding how to make it work on the board and what options to select. I’m trying to figure out what options I should select on the online config tool. Its not very clear and uses terminology that doesn't match/hint the sensor type.

@P3D , did you figure our what options to use?

Ok, I just tried adding the probe offset on one side of the green coordinates and minus’’Ed on the other and that seems to have done the trick.

So my coordinates for M557 is now X-170:-5 Y-122:94. Probing is perfect now.

Argh, so frustrating!

Everywhere I look it’s seems you only get part of the story to fix your issue, only to find that you need some other special setting….

Here is a question. Why can’t there be a simple webpage that helps to auto generate the code you need to copy paste into your config file(etc.?)

Kinda like the one I’ve used to create the bed.g file (which didn’t help because it’s didn’t account for my probe offset).

Surely there mush be a way to make this much easier than it is trying to find all the pieces in the puzzle hidden in all of the forum??

For example, it could would like the reprap config tool.

Have it ask what size your bed is; what type of printer it’s is; what’s your probe offset; what is your axis limits considering your prob(or other equipment attached to your print head).; what duet board are you using; then, when you’ve put all of this in, it generates all the settings you need to copy/paste and where.

Surely there has got to be a way to do this??

Anyway, onto my issue. I have FINALLY figured out how to complete my first successful G29 without my probe going off the bed (had to minus the offset on the map limits). But that’s where the advice I’ve found stops.

Nothing about what to do when your height map is not centered on your bed, but offset because of the parameters you put in for the map to compensate for the offset.

there doesn’t seem to be any topics that speak on how to correct this either.

If someone could create a tool like this, it’d be a massive public service!

Little help?

After trying to figure out and finally figuring out(I think) how to input mesh grid for my printer which has center of bed as origin; I have decided to make my origin back to its original place in the corner.

I've decided this because I am not getting a good consistent squish across the various spots on my bed. Plus, I am not confident that the mesh on my bed that I got is correct. (See below)

I'm just about to redo my trigger height, but I have a question. In the guide(https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe), it calls for you to bring your nozzle to the center of the bed and do the paper test. Afterward, it asks you to begin your trigger height routine. BUT, here is my question...

Seeing as my probe offset is so far(x-60 Y-12), isn't it a better idea to bring the probe over the same spot I did the paper check to make sure I have a consistent base height? Or, does the programming for the G29 somehow compensate for this?

Thanks in advance!

@Phaedrux Before I continue, I wanted to say a big thank you for your help before! It's good to have people like you helping us all make the most out of our printers.

@Phaedrux all the coordinates you see in the green are ones where the sensor stays over the bed. But, so some reason when I put my M557 x-110:55 Y-110:82 S10 other first probe starts at x-50 y-98. 🤨

Then it proceeds to keep probing until off the bed on the x axis, which I then have to emergency kill it.

@Phaedrux When I input the ranges of the green the probe still goes over the edge. Any pointers?

Ok, here it is....What do you think?

Thank you for this. I'll fill in and see if it helps. I'll post image if I still can't work it out.

In the meantime, here are some pics of my setup. With the Induction sensor I have, this is the closest I could get it...

Ok....I am still so confused!

So I took you suggestion about jogging head around to find what I can work with based on my mods.

As a result, my min/Max axis has changed.

Below is my config. What calculations should I use to figure out how to define the grid again?

Thank so much in advance!!
