Thanks, I realized I was just using the wrong IP address to access the Duet Wifi. And I realize now that the DWC lives on the Duet, not on the PC. It has been quite some time since I set this thing up and I struggled with it a bit. I guess I should probably attempt to update the firmware and all. I first need to reconfigure Simplify3D since I lost all it's settings when I lost the laptop.

Thank you...so there must be an SD card in there then. Couldn’t remember. I guess I’ll have to take the printer apart to access the USB port. I don’t have an SD card reader for my PC. Very strange why it has stopped working.

Thanks, guys. I never use the SD card and am actually not sure there’s even one in there? Unfortunately can’t check without disassembly.

I have a Google router, forget what it’s called but it’s a round cylindrical device. It kind of has a mind of its own and some settings don’t seem to be adjustable. It had been working fine with the Duet but I’d always have to look up the IP address to use the web control because it changes frequently. I’ll try and check the link for troubleshooting and hopefully I can make sense of it. I struggle with computer and networking stuff!

Out of the blue, my Duet WiFi (it’s an older board, maybe a year or two old) has stopped connecting to my network. When I check the router, the Duet doesn’t show up. However, when I check for available networks with my phone, the Duet is there. Any thoughts on what happened or how to fix this? The Duet is not easily accessible and would require I disassemble the printer. Hoping to avoid that if it’s something simple that I’m overlooking.
Thanks!

Hi David,
It's been quite some time since I've been here as the Duet Wifi had been working great. The laptop I used just died and I can't figure out how to get the DWC installed. I found the github site but that site confuses me to no end. I downloaded the DWC zip file but can't figure out what to do with it. A google search for installing it also comes up with nothing. Please help.

Following the advice found in another thread (it was confusing to me at the time), I managed to figure it out.

I connected my PC to the Duet. Then went to 192.168.1.1. A screen came up (confused me the first time around as I didn’t understand the procedure) and I selected my new router and entered the password for it. Rebooted the Duet, reconnected the PC to the router, and it’s working!

I bought a new router and can’t figure out how to get the Duet to connect to it. I did a search but since I don’t know what firmware version I have on the Duet Wifi, I’m not sure how to proceed. It’s been some time since I updated the firmware and surely have forgotten how to do that. I know it was about the time babystepping was added. Anyway, I can see the Duet when I search for available networks but don’t know how to proceed. Any advice would be much appreciated.

Thanks!

Now that I reread what I wrote, I suppose it's somewhat like an extruder. But the feed/stop/retract is not written in the gcode, but rather is from an external input signal. And the "retract" would be in 2-axis. Wow, this is actually more confusing that I initially thought!

Hi Tony,

I'm slowly learning myself how it works but it's a machine that cuts metal via spark erosion. The wire is what is electrically charged and does the cutting. I suppose it's somewhat analogous to a 2-axis hot wire foam cutter. However, the electronics must sense when the spark starts as the wire moves close enough to the part being cut, when the spark is established, and when the wire shorts out. When it shorts out, the cutting action stops and the wire must be moved backwards in order to break the short, then move forward again to reestablish the arc.

I'm assuming the power supply for the wire also has a means of sending a signal to the control electronics. There are a few DIY power supply plans and such available but the big challenge seems to be the motion control. I'm a complete newbie when it comes to this stuff. I can see how you could use the Duet to control the steppers and even stop the advance when the wire shorts out. What I have no idea how to do (and perhaps it's not possible today), is how to make the wire back out…basically in the exact opposite direction it moved forward.

Does that make sense?

Thanks!
Scot

Okay, I guess this may be a little bit of an odd question but here goes…

I've been wanting to build a wire EDM machine for a while now and have finally found plans for the power source and mechanics. The mechanics are quite simple, just X-Y motion is necessary.

The question is can the Duet Wifi respond to a signal that would tell it to advance/stop/retract while following the path dictated by the g-code?

Hope the question makes sense?

Thanks, Scot
