base: master
Are you sure you want to change the base?
Conversation
Do we have really now be careful not voiding our warranties just because we are trying to make the product better? |
I don't know @workinghard , I'm just following the spirit of the new changes from Prusa, unofficial firmware voids your warranty. I accept this, but want to make sure others are aware as well. |
I have submitted this pull request so this fix can be merged into the official release so that nobody has to worry about that. |
@vertigo235 We had more issues with MK2.5+MMU2 in the past that‘s why I‘m asking for the printers used. |
Also there will be some sort of developer program to allow folks to improve the product without risking their warranty, but there is no details about that yet. |
Hey, This might sound like a stupid question.But how do I flash this into my MMU. I'm also having this issue even after calibating finda and IR it randomly starts flashing after an unload. Just wanted to know how to implement this. Thanks |
@ajax122-bot As this fix is not merged into the main branch, you can check out the one from vertigo235 (https://github.com/vertigo235/MM-control-01/tree/flashing_light_fix), compile it and flash to your MMU2. |
I started experiencing the issue again I think that it might be exasperated at the least by crappy connectors , wiggling the connections on the back of the MMU2S seems to help for a bit. I am thinking about crimping some new molex connectors. |
I flashed this into my mmu. Still got it randomly in between prints but the frequency of it happening has reduced significantly. Really at a loss as of why it’s happening. Maybe it’s the wires or something . So frustrating at times! |
Yeah, I think this helps but I believe it's really just crappy connectors. I know some folks that got a new wiring harness for their MMU2S and that resolved it. |
@chriswal I think you are right, still get the issue occasionally, I will try your change |
voltage drop is probably related to prusa3d/MM-control-2.0#15 |
After installing 1.0.6 I started getting the 10 flashing light fix pretty regularly. It appears this is some sort of voltage drop detection.
Reviewed the changes and noticed that the currents were changed pretty significantly in 1.0.6 so I decided to drop them down. I did also increase the homing current a little.
This seems to have fully resolved the flashing light issue for me and at least two other community members have verified the fix. I will leave their names anonymous as to not risk voiding their warranties due to using non official firmware.
