Welcome to the SeeMeCNC Community

I would email support.

(psst! DHCP is *after* the connection is made. :D ) I suspect the root cause is related to both radios having the same SSID. It may also be specific to his particular make/model/firmware of wifi access point. It's certainly worth digging a bit more to see if the problem can be properly characterized ...

I'm really glad you got it working! Great catch on the 2.4Ghz restriction - I wasn't aware of that myself! (All of my WiFi access points use different names for the two different radios, so I NEVER would have caught this myself.)

Are you sending commands to the board via the screen, or via the usb cable? If you're using the screen, try using the USB cable. You'll need a serial terminal (YAT works) to talk to the board. I *think* the baud rate is 115200, but I'm not sure. That should be easy to look up though. I flinched at ...

You're welcome!

I would contact the Duet3D folks directly. They're best equipped to help you with this one.

g.

Heat the hot end and the bed, and while they're heating, check the 12v output of the power supply. It shouldn't be less than about 11.5V.

g.

I think I mentioned this before - if there's a wiring issue to the HE280's PCB, the firmware will hang on initialization, which it appears to be doing in your photo.

g.

Can you post a photo of what your screen looks like?

g.

Can you control the printer through the front panel?

g.

sus post is sus.

g.

They're nearly identical mechanically, but vastly different electronically.

g.

I would check the hot end wiring. If memory serves, the firmware will hang on init if it can't talk to the accel. circuit on the HE280.

Go here: https://www.seemecnc.com/pages/downloads and scroll down to the "Rostock MAX v2" section.

g.

What slicer are you using? What are your retract speed & distance set at? What's your nozzle size?

tnx!

g.

This might help you out: https://github.com/seemecnc/slicing-pro ... Cura%204-6

While the profiles are for 4.6, there's some dual extrusion ".curaprofile" files in there that may help.

g.

I'd be curious to see what the print walls look like.

Weird idea, but have you checked your extruder drive gear and nozzle for wear?

g.

Yeah, but it's very much worth it.

g.

Those self-inflicted wounds hurt the most.

Glad you got it sorted!

g.

Screenshots of errors would be a big help in assisting your problem diagnosis.

g.

Right, but in order to get that kit, you're going to have to contact them directly. It's highly unlikely that they'll see your post here.

g.

You need to email them directly.

g.

I suspect if it fits, it would work. If the idlers you have now are working, there's no reason to replace them however.

g.

...and thus spake dc42!
