HELP! Duet 2 WiFi Configuration and DWC Upload???
-
All the M280 commands that need to be changed are only in the deploy and retract files, right?

Not sure what's missing/what I'm doing wrong
Your M557 command is invalid. I think it's because you have the max and min values reversed.
-
I don't know, that's why I asked. all you said was
Likely M280 P3 S160 I1 in your case.
and I was asking about the mesh bed
I thought the link was referring to the reset and the command was referring to why my Probing for the height map wasn't working

I hadn't seen that post yet. I was replying to the question about resetting the bltouch without rebooting.

I have them reversed because when my X and Y are homed, their "0" values are actually 229.5 and 231.1
-
Ah, got it.

The firmware doesn't see if that way. It just wants the minimum extent and the maximum extent.
Please send M98 P"config.g" and see if it complain about it. Or just copy and paste your M557 line into the gcode console and see if it complains.

There you go. Flip your values for X and Y and try again.

It seems to not be going all the way to the left and way too far to the right

Should I add (-) somewhere idk I'm just guessing
-
How did you measure the XY offset of the probe from the nozzle?
Keep that offset in mind when you set the M557 range. If you try and probe a point that it can't reach because of the offset it will give you that error.
You can also just use a full zero to max range for M557 and just let it skip the points it can't reach. Other than the warnings popping up it will still generate a heightmap for the area that it can reach.

After a couple hours of tuning I got this height map. Do you think its good enough, or should i keep adjusting the bed and do another height map?
This was done with my heaters on
And this was the one I did with the heaters off

Those look pretty good actually. If you want to test the effectiveness of the mesh compensation try printing something like this
-
Ok. I can print that now, right? So, like no more setting up the mesh compensation, or saving it to the SD Card?
What is the Z=0 datum for? Is that just if I want to use a different height map?
Before I checked my points with the probe, I would home Z and then bring the bed down 6.5mm and command the probe. Is that the Z datum? Z at 0 or at 6.5?The only other thing on the Mesh Bed Compensation page is Compensation Taper. Do I need to mess with that at all, or no?
I found this a while back. Does it apply to me? or is it the same thing I'm doing currently?

Yes you should be ready to go. The mesh is saved to the SD card as soon as it's created with G29. It's stored as heightmap.csv in the system folder.

What is the Z=0 datum for?
A datum is a fixed reference point. So in this context, all it means is the position where Z=0. In other words, it's where your bed surface is. The Z axis position displayed is the distance between the bed and the nozzle tip. This gets set by the probe when you home Z.
@pcnoobneedsmajorhelp said in HELP! Duet 2 WiFi Configuration and DWC Upload???:
Compensation Taper. Do I need to mess with that at all, or no?
That's up to you. It reduces the amount of compensation applied over a set amount of height. So in your case the bed is fairly flat and the deviations between low spots and high spots is pretty small. You could set a taper off value of 20mm so that by the time the print reaches 20mm it's not compensating anymore. Try it both ways when printing a simple tall tower and see what it does differently. You probably won't be able to tell.

You're basically already doing that using G29.

So before I do my test print (since I installed the new motor) I wanted to recheck my E-steps, so I did, and It's all good. Then I rechecked my max feed rate, and it went from 5.98 to 1.45mm/s. Is that going to be enough speed? If not, is it kosher to increase the motor current past 80%, or would it burn out on a long print/fry anything? Right now my new motor's current is set to 1200mA

If the new motor has much lower torque than the previous one that might explain it. Usually the shorter the motor the lower the torque.
Increasing the current past 80% is possible but heat becomes an issue and there are diminishing returns. Ultimately it won't help that much.
How did you measure the max flow rate?
