Unsolved Horrible banging noise
-
Hello,
I have a problem with my newest Caribou Duet printer. I used all the same parts as in my perfectly working one (0.9 degree stepper LDO-42STH48-1684MAC) but a Duet 3 Mini 5+ Wireless. I'm using the firmware (3.3, tested 3.4 and no difference) and config from the Caribou website (https://caribou3d.com/Software-Duet/Duet3Mini-Configuration-Macros/01_Latest Version 1.0.0/CaribouDuet220/E3d-SE/SUPERPINDA/CC100-Duet3Mini-Caribou220-NSP-Build19.zip). However, something isn't right:- movement is possible, when moving the axes manually from the DWC it's fine (albeit a bit noisy, probably it's using spreadCycle)
(see https://www.youtube.com/watch?v=C2JrvcvyYhE) - however, if I print I get a horrible noise, like metal banging on metal (https://youtu.be/HtB3_VIQFys?t=7). It's only there in faster movements, if the printer slows down it disappears. The printer also makes grinding noise when moving from the purge line to the print
- I cannot find any mechanical source of the noise, here I am showing that there is nothing that is loose or can move: https://www.youtube.com/watch?v=c_bFNBjb-7E
- the prints come out perfect, so if there would be something that is mechanically loose or incorrectly assembled, I don't think the prints would be flawless
- the z-axis is also louder than my other caribou Duet (https://www.youtube.com/watch?v=tQQLP8KZQ_8)
Could this be an issue with stealthChop? I've read that there might be problems with stealthChop and 0.9 degree motors. I tried switching to spreadCycle only, but then homing wouldn't work.
I have attached some more pictures of my printer and the print that came out without any signs of mechanical issues
- movement is possible, when moving the axes manually from the DWC it's fine (albeit a bit noisy, probably it's using spreadCycle)

@weeky go into console in the DWC and type in M122 - and paste that resultant code output into some </> code brackets in here - lets see exact firmware.
Also do the same for your homeX.g and HomeY.g files under system.
Probably a good idea to post your config.g as well

@weeky The fact that you say it prints OK, would tend to indicate that maybe some ancillary device like say the PSU or the Duet board mount is loose on the frame. Have you tried shaking the entire the machine to see if you can replicate it?
You could try printing something like a large cuboid with infill at 90 degrees rather than the usual 45 degrees. That would generate moves which are pure X and pure Y which might help to narrow things down a bit.

@deckingman - same machine, board and setup as the one on the threads I linked. Pretty sure its the stealthchop / spread cycle change over at certain speeds.

Here is the output of the M122 (I tested the newest Beta Firmware to see if it makes a difference, but didn't):

@weeky - nice work ...
I think there is a D2 / D3 parameter missing / needed in the "current-sense-normal.g" file that puts the drivers back into Spreadcycle in conjunction with the V100 parameter.
When I get homeI can locate mine im using on the voron - that took me all weekend to get workingM569 P5 D2 V2000 ; Take driver out of StealthChop Mode
M569 P6 D2 V2000 ; Take driver out of StealthChop ModeAdd the D2 and increase the V parameter some more than 100 to test and see ...
I also dont see an M915 call in any of your stuff. That sets the drivers sensitivity

Updated the above post - that is my current in use homeY.g - based upon MY motors and current settings - you mileage may vary. Now that said - I think your missing a few small items from your that may make a difference.
