Got the ezboard installed and Firmware flashed for ender 5. After setting the temperature on the bed and hotend. the encoder constantly clicks, its very annoying. any idea what is causing this?
Edit: It only seems to happen while the bed is heating. I dont think it does it when the hotend is heating...
I haven't seen that one come up before. Is it possible that there is a wire making contact on the back of the board in the printer enclosure? Can you post some pictures of the installed board?
It wont let me attach pics, there is no wires on the back of the board. It seems to be an EMI issue as it only seems to happen when I put the back cover on or stand it up on the metal desk. But weird it doenst do it with the hotend.
Edit: when I try to add pics, it says Opps! Something went wrong. Please reload the page and try again.
@rtremmel can you try uploading again? Just changed some of the server settings to allow larger uploads.
Here is a video of it. I know its dark, but when I pick it up off the desk it stops, but when i put it back down it starts again. The back cover is off and I have a piece of aluminum under it. It does it all the time when I put the back cover on it.
Wiring looks good. Did you check the grounding on the PSU? Is that the Landy or a Meanwell? We had another guy with an Ender 5 that was having odd electrical issues that ended up being the PSU, not the board, that was a Landy brand.
The ground is wired from the plug. It is a landy.
It may be the PSU. Please check that it is actually properly grounded: https://www.th3dstudio.com/knowledgebase/printer-grounding-how-to-check-your-psu-and-grounding-your-bed/
We have seen some issues with the Landy PSU's. If it is not properly grounded to the chassis like Tim said, there could be some EMI for sure.
@rcabor I just got off the phone with another guy that has the Ender 5 with the landy. I am sending him out a Meanwell to test to see if that fixes the issue. If you can run your stock board for now until we figure out what the root cause is I would appreciate it. If not you can email firstname.lastname@example.org and we can setup a return. I don't think a new board would fix the issue as it looks like its a general problem with that machine + PSU combination.
Tim its interesting that the stock board doesn't have a problem.
If you think it's a faulty board you're welcome to send it back. We don't handle returns through the forums through but you can email Support@TH3DStudio.com with your order number and a link to this forum post and we'll get the RMA setup.
This was happening to me but it was when I turned on the parts fan below 100%. Try removing the display unit from the rest of the printer to see if it goes away. This will let you know if it's a grounding issue between the ps and the chassis.
I checked the power supply with an ohmmeter and it is grounded to the chassis. 0.1 ohms.
I am not in a hurry to send it back. I am a test Engineer by trade for a company that makes Radar Transmitters and High Voltage Power supplies so I dont mind experimenting with these things. I have performed a PID autotune on the bed and hot end, but it made no difference (hoping a less aggressive bed heat would reduce the issue). I disconnected the display and I am currently printing through Octoprint and it seems to be printing ok. I have a lot of different ferrite beads at work, so monday I will bring a few home and try that.
rcabor we just bought a new Ender 5 that should have that Landy PSU in it to test on. The one we have here that testing was done on has a Meanwell and didn't have any issues. I will update everyone once we get the new printer in and get the board installed in it.
