shaper graph low y acceleration V Core 500
Just wanting tips on how to improve my y acceleration wondering it is a vibration issues as I was unwilling to cut most of the wires short to path them as in the v core 500 documents.
VC4 500mm Hybrid Belt Tensioning Trouble Shooting
Having some trouble getting a good clean input shaper now with the Hybrid Y installed. I'll start from the beginning:
First three photos are belt tension and the X and Y Axis input shaper. All three look good. CoreXY Y Axis MZV is 3,400.
Fourth photo shows the initial hybrid setup giving me two peaks. At this point, I was getting lots of 2 and 3 hump EI recommendations (not great)....
vc3.1 new toolhead
been running the EVA perfectly fine for a while now, just switch to the RRTH (or at least my modified version of it) and I can not fix a resonance graph in the same way or with the same ease as I used to.
first run didn't seem too bad, decided that the lower belt needed to be tensioned more but I had run out of movement on my tensioner so I had to pop off the grabber and trim down a few teeth and now it is even worse.
I'm gonna walk away from the machine for the rest of the day so any input (heh) I can act on when I get back would be super helpful....
Can't get good graphs on VC4 400
This is 24th graph I did today. After 3 hours I still can't get the belts to align. It doesn't make any sense. When I loose the upper belt it doesn't get closer to the lower belt. Either the second smaller peak dissapears or nothing changes. I tried realigning Y rails, the X gantry. Measured distances between various points to check for obvious frame issues.
Solution:
Getting there finally! I unbolted everything I could and tried to alignt and bolted again. This is the latest:
VC4 400: Second peak not appearing
Hey, first time tuning belts on a coreXY. Not sure why the second peak is not appearing. @miklschmidt suggested before that my belt tension is too high, but I matched both belts on the one peak I have and reached low end of 1e6. Is it still too high, or can there be another explanation for this issue? There might be some noise due to the fact I didn't finish cable management on the toolhead yet, but I reckon it doesn't influence the general look of the graph. Thanks!
I need help on with my graphs (V4 500)
Any tips, trick , obvious problem are welcome to be discussed and shown here to achieve a good enough graph so i can finally move on and print to my heart content. FYI this is corexy only, the hybrid motor are unplugged so far
Belt tension graphs degraded
Removed my belts off the printer to trim them to exact same length and the reinstealled them and my previously wonderful tension graphs have turned to rubbish.
Have not been able to track down the culprit yet. Driving me nuts. Whats a list of what I should be looking for?...
VC4 500 hybrid y resonance speed low
I just ran the resonance tests again, and I'm seeing charts that look great for X, but y is showing half of what I'd expect for acceleration speeds. I'm wondering what I missed.
two peaks on belt tension
they're just about the same. but idk what to do about the secondary peak. my printer does NOT like printing around 100-120mm/s, but is perfectly quiet below and above that range.
What do you guys think? Vcore 300
Belts tensioned to 94hz through spectroid (what an incredible app by the way) with x gantry all the way on the Y endstop.
How does this look for a VC4 500
Never had a machine this size so I'm not sure if the recommended accels and graphs are good or not. This is a hybrid machine so I expected Y to be higher than what it is
Y all over the place
Hey there, I know this is not a vcore printer, but I hope someone could still help me.
I just run input shaping with an adxl345 and the X result looks quite "normal" but y is all over the place.
Does anyone have some tips on what could cause this?...
Vcore 4 only has one large peak...Is this ok?
Is this acceptable? I only really have one big peak here. Is something binding? New Vcore 4 500 build. CoreXY, not Hybrid yet.
Trying to make sense of this. Is this fine for a vc200?
Just started tuning my printer and I was wonderingf if these results where fine or if there's someting i should look in to.
Comparison between ZF (slight clearance) and Z1 (medium preload) HIWIN linear guides on X axis
I got HIWIN linear ZF (slight clearance) in January due to irrelevant reasons. I bought the Z1 version (medium preload) for the X axis at least. The pictures show measurements BEFORE (both X and Y axis have carriages with slight clearance) and AFTER (X axis with preload, Y axis with slight clearance), at ambient and during warm-up. The measurement took place within about 12 hours of each other.
X axis and Belt tension measurements without comment. I find it interesting that the Y axis looks better, but the PSD remained at the same height.

VC3.1 400 Enclosed - Ringing only on X after Input Shaper?
Printer:

Spike in y shaper at 80hz to 100+ hz
Been trying to work this shit out for weeks on my open V-core 3.1 400
1. belts are not riding up or down on any of the idlers
2. using FMMM with BRS lever m1
3. aligned my y-axis linear rails with provided alignment tool while loosening all bolts on rails and on xy joiner carriage
4. Custom vz printhead with short goliath hotend...
