This is not the centerline I know...what happened?

Uploading a video to youtube now. It shows the 49 and the H being carved in the method I tried to describe above.

When you install the rock.... Splice the old QC video sound and the ROCK sound back and fourth to hear the difference in noise level....

Curiosity make me ask this question...Have you used this same font and file exactly as is in a prior version of design? Just wondering if it has anything to do with the font itself instead of the version. I have heard on this forum in the past of people having certain fonts just not carve right...like missing letters and such.

I don't have a clue but check if the ztruck is tight enough

What is that chattering sound in the video? Sounds almost like the flex cable is binding or something..

After watching that video two things are clear. (not saying it's the cause but needs to be addressed anyway)

1) The RPMs are all over the place
2) That flex shaft definitely needs to be lubed.

That shaft should not chatter even when doing a deep raster carve let alone a shallow vector cut.

What font are you using? Forgive me if I missed it in the posts but, if anyone loading this MPC (including Alex) doesn't have it, Designer will just default to another one and thus render any testing by others irrelevant.

From the video, the CW is most definitely carving along vector lines so I think we can rule out any "raster like" carving going on.

Unless you've already used it successfully in the past, my "guess" is it's the font you are using and centerline doesn't much care for it. I've run across a few in the past myself that simply didn't cut right.

This is my conclusion as well. I just ran the same text through v1.134 and got exactly the same results, although it was in 17 minutes instead of 34. The font is Copperplate Light.

I ran some centerline text last week(different font) and everything worked fine. I just haven't run into this issue before with fonts not carving 'well'.


Regarding the noise my machine is making, I think it's a combination of worn QC issues (got the rock chuck on order) and possibly my flexshaft hole not being totally square (from removing the QC a few times with the wrong tool.) I have a brand new motor and rpm sensor (like 2 hours on it since it was replaced). Are you still using Crane Cams Assembly Lube for your flexshaft? That's what I switched to, and I don't have a heat buildup problem. I could add some more lube, but I was concerned about over-doing it.

Thanks.

While I can't comment on the QC without actually being there, I did watch closely on the video and saw no signs of it running out or vibrating. Now I couldn't really see the bit. The chatter I heard was definitely the shaft. I've heard that enough times to bet on it...LOL

Now an out of square drive hole could certainly be a part, if not all of what's causing that chatter.

Good deal on the motor and RPM sensor. Sounds like you're on top of that. I would recommend however (unless you have a lot of hours on the motor) just replacing the RPM sensor first. Hey, if the motor you have runs right with a new sensor, get as many miles as you can out of it and keep the new one as a spare.

Absolutely on the Crane Cam.... I will never use anything else. You don't need much at all. I haven't even used half of that first small flex package yet. I've only had to lube the flex shaft 3 times since using that lube and I have over 250 hours of cut time.

After wiping off the old, just a thin film of new is all you need. Also, I go even thinner after the section where it turns down into the Z truck.

One more tip too (regardless of the lube you use), if you notice the shaft core is wound in a spiral. I make sure that spiral (like a screw) spins pulling up and away from the spindle. This will "aid" in not allowing the lube to run down on the bearings. Although I've never had an issue with that using the Crane Cam.

EDIT: I just checked and I have copperplate "gothic" Bold and Light. If that's the same, chances are a lot of folks have it so it may just indeed be a "bad" font for Centerline. Now if Alex's carve used the same font as yours and it carved OK, we're back to finding the cause which may indeed be mechanical in nature then.

looks like centerline is cutting twice.. you said that you rolled back to 1.134 and had the same results.

Did you roll back the firmware two? as the firmware drives the cutter not the software so to speak.

As a side note for testing you can keep 1.150 Designer installed but use 1.133 firmware to test.

PS thanks for the video..

Good pont buddy! Didn't even think of that myself.....
