Any idea how to get rid of these vertical bars? My X is left to right at 0.7 Line Interval.
This is Mirror Acrylic, and the bars are definitely on the Engraved side.
I first thought I wasn’t removing all the mirror, but another pass, they remain.
ok, so noticed X gear slipped on shaft, and belt was not lined up and at an angle.
It grinded it down somewhat, so need to buy a new belt now.
Best place to get belt?
Which was harder, the motor shaft, pulley or belt?
I suspect the pulley was soft and wore. Order one for replacement and you can try and limp along until it arrives. If it wobbles, it will probably show in the end product. How much depends on the wobble.
Belts you have to wait for, but it’s the same thing, how bad is it?
It has to come apart and it should be relatively easy to check and see what wore.
Hi Jack,
The set screws were not very tight, and pulley slid on shaft, which put belt at angle, and it rubbed against pulley, which tore into it. Took me awhile to find that small of an allen wrench in my toolbox drawer.
I was able to use a dental tool to scrape the rubber crud out between teeth and can almost see metal, so it will work for now, but definitely need new belt. Don’t think I need pulley, but might as well if ordering belt. Saw that it was like $3 on cloudray.
I did notice the Stepper was very hot, but not sure if that’s normal.
I ordered a lens tube and it came in about 48 hours. I order another one along with a nozzle. Customs from China called my wife a couple days later wondering if it was a medical laser… Then took it a week more…
I don’t know what to think anymore… pays my money and takes my chances like everyone else. I have never had a problem with them.
Just looked at the picture, should have posted that with the original post…worth 1k in words.
That looks kind of wasted, it looks like areas have no teeth… You’ll have to run a test and see how it does. Keep an eye on it. You may have to work on one end or the other…
Yes, pic was after I fixed pulley and finally tighten the 2 set screws.
I did run another full sheet afterwards, and it still had some x banding, but not as bad.
Just set the tension properly and it will be fine… lol… Wish I could just tell you, but like most things, you have to do it to get a handle on it… I’ve had a couple different belts on the X axis on my machine. The current one is very hard compared to the original that came with the machine.
This is how I’ve done it when totally lost. If it’s an area I can duplicate the problem and make a short test pattern that shows it quickly. Change the tension, then re-run your program and see what changes it makes. You can see where it needs to be, if that’s the issue.
All of these timing belts are different. The one that come stock are generally low quality and vary in the material. Also some are not supposed to be cut. They build them different if it can be separated.
