RRF36 disconnecting mid-print
-
@justGuner how do you have that connector wired? post a picture.
-
I feel like I should mention that this system worked for the last month, and only just now that I started to print faster it began showing the initial behavior.
-
@justGuner With the power off unplug that cable and with a meter check the resistance between them.
As I said above I suspect there is a problem with the CAN bus wiring. Unfortunately if you keep flexing wires they tend to break and have other problems. Maybe post a picture of how the wires are connected at the print head.
-
@gloomyandy do you mean the white and yellow wires?
Also, the board refuses to boot up if i have the can adapter connected but not the toolboard.
-
@justGuner If you disconnect the connector from with the white and yellow wires in it from the CAN-FD adaptor but connect the CAN-FD board to the mainboard does it boot or not?
-
@gloomyandy no, it does not.
-
@justGuner Sounds like your CAN-FD board may have died then. Not something I've seen any other reports about. Probably worth examining the CAN-FD board to see if you can see any sign of damage or anything shorting any of the pins.
It seems very odd that the maiinboard seems to start up and only reboots after a short while. If you unplug everything else from the board and just have the CAN-FD connected do you seem the same issue? When you are running these tests how are you powering the board?
-
@gloomyandy I honestly can't observe any damage on the CAN-FD board. Is there a posibility that something might have happened to the exp ports on the skr?
If you unplug everything else from the board and just have the CAN-FD connected do you seem the same issue?
Yes, I still have the same issue.
When you are running these tests how are you powering the board?
The board is connected to a 24v psu. I have tried powering the board over usb as well (yes, I did move the vdd-usb jumper for this), but to no avail.
-
I'm about to buy a SKR 3, hopefully this will solve the original issue that started this thread. If it still keeps on disconnecting, I'll buy a new cable or replace the original wires that it came with and hopefully that will be the end of it.
-
First time power on with the skr 3 ez and the CAN-FD adapter went fine. I guess that means that something went wrong with the exp ports on the skr 2.
I need to print a new mounting bracket for the new board before doing more in-depth testing. I'll also ubdate everything to 3.5.1 .
-
@justGuner It may also mean that you have an intermittent problem with the wiring that movement during printing triggers. I guess you will find out over time!
-
First print with the new board at relatively high speeds (compared to the previous setup) and no CAN disconnects! I guess this means that the cabling is fine.
