Trying to fix my dual markforged (HAQ-XY) kinematics
-
Hey!
I am breaking my head over a serious print-quality issue with my machine...
- When printing the ringing tower in vase mode (M204 P5000 T10000, outline at 150mm/s, autocooling off) the layers look very good, with no ghosting at all and very good print quality
but;
When doing a "real" print, I get soooo much layer missallignments, even if I set "M204 P700 T1000". Layers do not seem consistent...
The images are 2 different filaments, but this happens with both heads, at all places on the bed, with all filaments...
I suspect the X, Y, and U axes are poorly synchronized. This is also because it only happens on Y moves.
I already have checked belt tension, set screws on pulleys, mounting of idlers, motors, all linear rails on X and Y, but it is a serious wobbleI have already set a test where I move Y quickly front and back, and you see the head moving left to right;
(see video; WhatsApp Video 2024-09-06 at 16.05.54.mp4 )Does anybody know what could be going on??

@SanderLPFRG ...looks like an elefant trunk
I'm not really familiar with the dual markforge design, but could you repeat the back and forth test in the middle of the bed, then on the outer edges?
If it shows less wobble in the middle, you might see racking. -
@o_lampe It is the same everywhere.
Also happens on slow prints..
Moves with only X or only Y motors (left to rigt, or diagonal) are fine, so it only happens when a move requires both motors

@SanderLPFRG what firmware version are you running? Please send M122 and post the results. Also post your config.g, and the response to M669.

Thanks @droftarts!
Here you go, if you need anything else, please let me know!

@droftarts to aid troubleshooting, I made 4 videos of short moves (20mm) at 200mm/s, at 10.000mm/s^2;
Only X-motor (Pure X-move);
Pure X.mp4Only Y-motors (Diagonal move to front-middle);
Diagonal.mp4Both X and Y middle of bed (Pure Y move);
Pure Y middle.mp4Both X and Y all the way at left of bed (Pure Y move);
Pure Y left.mp4You can see that the printhead only wobbles side-to-side on movement including both motors, and it is the same on the exact middle and all-left on the X axis
-
@SanderLPFRG This may be noting to do with your actual problem, but when watching the "Only Y-motors (Diagonal move to front-middle)" video I can see something in the blurred background wobbling up and down (possibly a belt?), it seems to me that the wobble in that may match the wobble we see in the head in your other videos. Either way in general having anything wobble like that on a printer is probably not good!
-
@SanderLPFRG I agree with @gloomyandy, it looks like something is wobbling. Perhaps an eccentric motor pulley or bearing, or a failed part of the belt?
Ian
-
@droftarts yeahh it is a big printer, belts are hanging free for 700mm, I need to tighten them a shitload to fix it, could this be the issue?
-
@SanderLPFRG Hard to say, but the wobble in whatever it was in the background did look to be at around the same sort of frequency as the movement of the nozzle in your other video. I'd certainly say that it is probably not a good thing!
-
@gloomyandy said in Trying to fix my dual markforged (HAQ-XY) kinematics:
at it is probably not a good thing
Ill redesign the belt tensioning mechanism and the belt mounting, when measuring it indeed looks to be too loose
WIll see what this does
