I’m curious if anyone else has experienced this issue or has found a solution.
The machine completely locks up whenever I attempt to connect to it via WiFi from my phone or laptop. The machine becomes unresponsive and requires a reboot.
I’m using the TP-Link AC600 USB WiFi adapter that Onefinity recommended.
I purchased the powered USB hub they recommended, but the issue still persists.
Thanks!
Did you try plugging in a wired mouse to see if it works? I think internal EMI is causing issues with the touch screen. I was having issues where the touch screen would flicker and than cursor/screen orientation would change. I didn’t have to do anything but turn on the wifi. I think I have it figured. Giving my fix a day to see if it works. If my fix works I will post it.
I tried using the ethernet connection, but my system wouldn’t boot up, and I experienced the same cursor issues. As soon as I unplugged the Ethernet cable and went to the same USB TP-LINK AC600, I had all kinds of wifi spots show up, and it connected like it was supposed to.
Cross posting this so it’s here too. Hope it helps.
I do a lot of radio systems work professionally and even more with software define radios. Because they produce radio frequencies and antennas are designed to pick up extremely weak electromagnetic fields, EMI is a constant battle to get the best signal. I say that to say, I have learned, sometimes it’s easier to defend your system better than it is to eliminate all the sources of EMI.
I upgraded my Onefinity from BB, so I had already grounded and bonded my dust collection system. Even with the dust system off and disconnected, I was getting errors however. The real telltale for me was when I would turn the wifi on, and half the time, the screen would flicker and the touch screen would loose orientation. That monetary pulse of Wi-Fi signal was enough to cause issue. As touch screens are very sensitive to electrical fields, I suspected the screen was my issue. I pulled off my screen, and at least the power cable (far left cable in the picture) seems to be completely un-shielded. Without taking apart the HDMI (far right cable) or USB cable, I can’t speak to their shielding. The power supply inside the HMI is unshielded as well. My guess is the screen cables were picking up common mode current from somewhere (like the Wi-Fi radio) and causing issues.
There is enough room at the bottom of the cables to snap on some ferrite beads and still fit inside the case. If it doesn’t work, they don’t cause any harm unless you break something trying to get them in/on the system. I happen to have some USB sized ones laying around, so I did throw one on each cable. I DON’T recommend unplugging the screen like I did. The Micro-HDMI cable into the Raspberry PI is a pain. Best to have someone hold the screen for you while you snap on the ferrite chokes.
My system has been on for 18 hours, I have done a few carves and just left the system sitting on, and have had no issues. No returning to screen problems or messages about stepper motor errors. Honestly, it seems like something they should have done in manufacturing, or install cables with built in ferrite chokes like what you seen on laptop power supplies.
I can’t guarantee this will fix your system, and no idea how Onefinity feels this effects their warranty. But in my case, them minimal cost (you can get 24 ferrite chokes for $10 on amazon, even cheaper for aliexpress) it was worth the end of frustration.
Picture of cables into screen. From left to right, power to system power supply, USB for touch screen, micro-hdmi to hdmi cable.
Nice little cavity below the Raspberry Pi where I was able to fit the chokes.
Makes sense, single board computer’s built in wi-fi isn’t great already. Putting it in a metal box only compounds the problem.
I feel ya, I put chokes on almost every cable in the garage. I have two machine one Masso one Redline. I put chokes on everything I can see.
Thanks for the feedback. I appreciate the suggestions.
I’ve already installed ferrites on all of the machine’s cables. What’s interesting is that I never experienced this issue before updating to 1.5.9. As soon as I upgraded to 1.5.9, the Wi-Fi lockups started. Nothing else in my setup or environment has changed, which is why I’m questioning whether the software update could be related.
To troubleshoot, I first purchased the recommended TP-Link Wi-Fi adapter, but that didn’t resolve the issue. I then purchased the powered USB hub that was also recommended, and unfortunately the problem still persists.
I’m not saying it’s definitely a software issue, but given that the only variable that changed was the firmware, it seems like a possibility worth investigating. I’m curious if anyone else started experiencing similar behavior after upgrading to 1.5.9.
