LIMIT POSITION not easily separating tool carriage

[IsItFasst]

VS-640 wouldn't "cut sheet" so I decided to the the LIMIT POSITION & CUT DOWN POSITION INITIALIZE procedure. But when I do this the tool carriage is VERY hard to separate from the head carriage. From what I understand when doing this procedure the magnet should let go so the tool carriage separates easily correct? I am having to force it apart. After the procedure completes I instantly get a motor error of either 0080 or 0040 when I go to turn the machine off. This appears to happen when the head tries to cap itself.

I have cleaned the encoder strip to make sure that wasn't the problem. I have tried doing the limit procedure about 10 times with the same results. Even tried moving the head carriage all the way to the left but it keeps giving the error when gets all the way back right trying to cap itself. If the head isn't capped when doing the procedure I get the "unrecoverable limit sensor" error. Currently can't do anything as I get the 0040 error when turning the machine on.

The machine was cutting sheets just fine. But recently had the main board out and since reassembly it started doing this. I guess my main question is shouldn't the tool carriage separate easily during that procedure? If not, what am I doing wrong? Seems pretty idiot proof.

easy solution, you are doing it wrong

At the start of limit position initialize, it prompts you to move to cap position. You have to lock the head, or it will fail. There is a youtube video by all graphics that shows the limit position initialize way better than i can type it out. The heads will separate themselves when done correctly, and make sure you only move the tool carriage to the left after they separate, not both.

The all graphics video is on a different machine if i remember, but it is the same on all print + cut machines.

I am following the directions exactly as shown from video at https://www.youtube.com/watch?v=uEYS7A6fpbU (this is my machine) and the tool carriage simply isn't disconnecting from the head carriage. It stays stuck to the magnet after it is supposed to release. I end up having to pry very hard to get the 2 to separate. That's why I am on here as this doesn't seem right.

I've had a lock get jammed, and took it apart to fix. It's just a ball bearing in a spring. took it apart, put it back together, and it worked after that.

The magnet works permanently, it needs power everytime when the carriages separate, and the carriage needs to be hooked. If you get motor errors 0040 and 0080, the magnet itself could not be the reason.

One reason for it could be truly a wrong limit initialize.

So I am supposed to force-ably separate the 2 carriages? In the video it looks like he just pulls on the tool carriage away from the edge with one hand. I have to pry hard to get mine apart. Which is what I have been doing but I am having the problems listed in the original post doing it that way which is why I thought this was the problem.

the heads separate themselves, which is why in the video it is effortless. If the head is not locking into place, the limit position initialize will fail 100% of the time. The head will only lock if a) it is moved into the correct position and b) the lock is functioning.

I've never replaced a lock, but strange things can happen. It's likely still the positioning.

Okay, that's what I thought as I'm pretty sure I have done this on my other machine at some point. Even if I get it to "take" the setting, it seems that the motor error occurs once the head tries to cap itself. The only odd thing I can see in the video that is slightly different than mine is the print carriage never really locks in place. I can pull it to the left without effort. Which is (I'm guessing) is the problem. Since that carriage never locks in place it won't pull the head. I guess I will take that apart and see what the problem is. Thanks for the input. Will report back.

I could see that the pin on the lock wasn't popping back up so I took it apart, and added some WD-40 to it. Now it works as it is supposed to. New limit is set and that is working. Now on to the next issue.
