Weird Tail
Using a VCore 3.1(ish) 500. Added the front end tensioners rather than on the toolhead.
I have behavior on my input shaper graphs that I do not know how to troubleshoot.
These are the graphs as they were last measured. That noise at the upper range, I have no idea what that is. They're not perfect outside of that, but I don't think chasing down that little bump on the lower end is going to be worth it unless I get the bigger noise down....
Dampening issue on Y-axis (VC3.1 - 300 enclosed)
Hi I have a dampening issue on the y-axis (I think). I believe that the left linear rail starts "rubbing" once I tighten the gantry bolts and have tension on the belts. I have been figthing this ever since I have the printer 2 years ago. usually, I can "fuss about" intill it's gone but not today. Any tips? (X-axis seems smooth as babies bottom...)
Solution:
btw, made a first successfull print. not 100% content with the quality yet but good enough to mark this solved. Thanx @mazas !
VC4 500 IDEX extra spikes on X axis
Why do I have 2 spikes about the same amlpitude? Tried to run oscillator on that range and don't hear anything loose. IDEX belts are installed, without them toolheads are moving both axes when running tests on X.
Y accel wont go above 2000 - vcore 3.1 with toolhead
I recently upgraded my printer to the new ratrig toolhead with the ebb42 1.2 board, (I also have the beacon but it was fine with the beacon before the upgrade) and now my recommended Y accel wont go above 2000. Before the upgrade it was around 6000 accel. When I move the motion system around it feels smooth and stable. I've check every screw related to the Y access and I can't find anything loose. I'm not sure how to read these graphs but hopefully someone else can help
v4 idex 500 tuning
hello,
so ive been spending a lot, A LOT, of time trying to tune my printer and ive reached that point that im only getting things worse.
as far as i understand x axis are not so bad, could be better but... meh. but the y axis looks terrible....
Wonky shaper, accepting ideas on what to check
Belts look good, but shaper graphs are weird, Y is almost clean but X is messed up, I have tried to find the source of the vibrations but can't seemingly find anything, any ideas?
VCore 4 IDEX 400 Belt Tension
Hi all,
I have come here due to the acknowledged lack of information for tensioning the IDEX variant of the VCore 4.
These are my Belt tension graphs, and with the lack of information, I have no idea where to really start with looking for things to fix. Built according to build guide, bed level is good, but these graphs seem to suggest something is very out....
Belt tension & shaper graphs
I have an enclosed VC-3.1 500. Doing the 1st resonance tests after a installing a new toolhead & AWD.
Can someone help as to what might be the cause of 3 peaks on the belt tension?
I think the X & Y resonance graphs look OK but would like suggestions for improvement especially on X....
VC4 500 Idex Belt Tension
This is my current result after trying for the whole day now. I cant get it smoother than this. I dont fully understand how to read the graphs i just did it by trial and error. Any Tips?
VC4 500mm IDEX
So I've been at this for quite a while now. I've made sure the gantry is square to the back motor mounts with no belts on it. I then added the belts on. I kept Y loose (almost slack), tuned the X and DC belts without issue to get either MZV or ZV recommended with usually 0% vibration. Both T0 and T1 X look good, and are giving what I think are reasonable accelerations with MZV (upper 6k) - first photo is representative).
I can also usually get T0 Y to be pretty decent, all things considered. T1 Y has been a significant problem, often with an unknown peak around 90hz. I occasionally get one around 125hz, however cannot find anything loose or vibrating on the toolhead (and I have T1 wire managed the exact same way as T0, which does not have this issue).
Furthermore, while I can ultimately get somewhat decent graphs and accelerations at the end of the day, I get significant dynamic skewing during printing. I suspect this is because my Y belts need to be so loose to achieve good Y IS graphs. Tightening them even slightly produces horrible Y graphs (third photo)....
Can't get second peaks to align
I've been struggling with this for a few weeks basically. No matter what i do they won't align.
Here is what i've already tried:
- evenly cutting belts
- realigning x axis ...
PI appears to crash after running GENERATE_SHAPER_GRAPHS and MEASURE_COREXYBELT_TENSION
(I hope I'm asking this in the right place, I can't post in https://discord.com/channels/582187371529764864/1047083812875677756)
I have an error after mounting an ADXL345 on my rat rig and I'm not as technically inclined as a lot of other people on here, my printer appears to keep crashing after doing a frequency test - this one occurred after I did the "MEASURE_COREXY_BELT_TENSION" command and any measurement command related to the ADXL345.
When running those commands the PI seems to either crash or enter some bizarre infinite loop, because it stops sending information to the web interface when starting its calculations for the shaper graph and it eventually disconnects from that altogether and I have to restart it to get it to reconnect and control....
Hybrid Vcore4 400mm where to trouble shoot?
Not sure how to trouble shoot this, why does the Y differ so much from the X axis? Also I believe the late peak has something to do with the eebb board not being attached to the extruder would this be a correct assumption?
VC4 500 Hybrid Belts graphs
Hello, I'm trying to adjust the belt tension of my hybrid system. These are the input shaper graphs so far.
Are them good enough? Why I'm having a "cut" on the curve?...
V4 500 Only Corexy for now.
Is there any guidelines to tune properly the belts?
I've tried more tension, less tension and I can't get a second spike....
Upper Belt Flatlines
V-Core 3.1. Tension is the same on both belts, resonance graph is confusing me. Upper and Lower belts look really close except for that 50-125 range. Something is causing the Upper belt to not register in that range. Any help?
V4 500 Hybrid second Y resonance peak?
Any ideas what could be causing this second peak on my Y graph? Is it likely toolhead vibrations since it's around 100Hz?
V4 500 IDEX Y Problem
Hello
I have the V4 500 Idex and every IS is good (mzv) only from toolhead 0 the y is bad. I don’t know what I can do anymore.
Do you have any ideas or Tipps ?...
