HELP! Duet 2 WiFi Configuration and DWC Upload???

[PCNoobNeedsMajorHelp]

@phaedrux

It's still doing it. I wasn't paying attention and thought it was going to crash but it didn't. It's just doing what it normally does with the line before the print but at the opposite corner. Is that just how it is now or can we change that.

-So its starting the print from the front left instead of the back right (where in want it to start from)

Thoughts?

Thanks,

It's also not automatically heating the extruder to the Cura printing settings

[PCNoobNeedsMajorHelp]

@phaedrux

Ignore that last reply. I guess the bed heats up first

[PCNoobNeedsMajorHelp]

@phaedrux

Just finished the first print. At the end of the print it went to the wrong corner (opposite of home positions) and then X and Y crashed violently.

[Phaedrux]

I don't see anything in your slicer end gcode that would move it like that at the end of the print. Can you share the gcode file itself?

We set it up as a left hand coordinate system to match what the slicer uses. I'm not sure why Creality chose a mirrored X and Y for the Ender5. It makes no sense.

If you really wanted to, it can be switched back, but requires changing the M574 endstop location and the homing directions.

@phaedrux

Before I switched to the Duet the X and Y wasn't mirrored.

[PCNoobNeedsMajorHelp]

@phaedrux

As long as it homes to the back right and starts prints from the back right, I'll change whatever needs to be changed

Before I switched to the Duet the X and Y wasn't mirrored.

They were, actually. Both of them. Which results in a 180 degree rotation, so that when looking at the front of the printer 0,0 is the back right, -X is to the right, +x is to the left, -Y is to the back, +y is to the front.

What exactly is the problem right now that you want to change it?

[PCNoobNeedsMajorHelp]

@phaedrux

Well if it was mirrored before then that's the way I'd prefer it if possible but yes 0,0 in back/right (I think that's why I was so confused with the values being plugged in when we were originally homing everything)

The reason being 1: After its done with a print it crashes into the front/left (that's the biggest reason), 2: My home endstops are right there in the back/right corner, and 3: Although its only mere seconds my prints will take longer, if, before each print, X and Y have to home to the back/right from the front/left where the last print ended, and then go back to the front/left to start the new print. It's just a lot of wasted time and makes more sense to have it start the print at the corner that it's home at.

[PCNoobNeedsMajorHelp]

@phaedrux

Do I just change my M574 X2 Y2 to -X2 -Y2? or would that not work at all?

Or I can just start the whole setting up endstop process over again from scratch

[PCNoobNeedsMajorHelp]

@phaedrux

Or is it my drivers that I need to swap

Well the behaviour after the print is over should be controlled by the slicer end gcode. Please post a sliced gcode file so we can see what it's actually being commanded to do.

Have you updated the cura with the bed size we measured before and put in M208?

@pcnoobneedsmajorhelp said in HELP! Duet 2 WiFi Configuration and DWC Upload???:

My home endstops are right there in the back/right corner

Endstop location can be at the high end or the low end. It doesn't really matter.

It's just a lot of wasted time and makes more sense to have it start the print at the corner that it's home at.

Prints are typically placed in the center, so the distance from one corner or the other should be the same. Do you mean it has to do a prime line first that's positioned at the opposite side? We can change the location of the prime line in the slicer start gcode.

But if you're really desperate to change it.

If you notice that after changing the directions that the axis is moving AWAY from the endstop instead of towards it, then change the rotation direction for the motor.

Ok. So.

-Yes, the axis limits are set up in Cura (Ok, cool, we'll change the end gcode)
-Prints are typically placed in the center, so the distance from one corner or the other should be the same. Do you mean it has to do a prime line first that's positioned at the opposite side? We can change the location of the prime line in the slicer start gcode.

1. Yes it's starting the prime line at the opposite side and then at the end, homes to the opposite side
2. So if that's the problem then yeah, I guess it would be in Cura. What lines would I have to change?
3. I think it homes fine but if the Cura changes don't fix it, I'll change those homing move directions and endstops in the firmware.

Thanks,

-Carson

For the prime line, where do you want it to start and end? Physically jog the nozzle to where you want it to start and end, and make note to the XY coordinates, then we can place those in the prime line.

For the end gcode, I don't see anything that would be moving it a large amount at the end of the print. It looks like it should be doing a retraction and then a small 5mm diagonal move to wipe the nozzle and then raise it. Can you maybe make a video showing what it's doing at the end of the print?

Here's what I plugged in (what I think it might be).

-I won't run anything until I get the okay from you. Just wanted to try and be proactive.
New Start G-code

New End G-code 1 of 2

New End G-code 2 of 2

[Phaedrux]

The prime line location looks good.

The end gcode has a problem though. You've changed the small wipe move of 5mm to a massive 230mm move. That's not what you want to happen.

The "present print" bit could be removed entirely. Is that below the first part? I hadn't see that before. That might have been what was causing the crashing. That move would make more sense for a cartesian i3 style printer with a bed that moves back and forth. The idea being that it will slide the bed forwards for you to get at the print. In this case you really just want the print head to move out of the way. The safest way to do that would be to replace G1 230 Y230 ; present print with G28 X Y which will just home the X and Y axis to get the print head out of the way.

@phaedrux

Yes, the second End G-code picture is below it when you scroll down

Ok. I've fixed a few things. Let's see how this is.

If all this looks good, I'll run another test print

Thanks,

[Phaedrux]

Yes that looks better.

[PCNoobNeedsMajorHelp]

@phaedrux

Everything looks good. After I get home from work tomorrow, I'll do a few different tests, other than the cube and just check everything out to be sure.

Thanks again for all your help! I couldn't have done it without you!
