Sticks at the end of X Pro V5

[dustypilot]

After using my machine successfully for 4 years, I finally tried a full-bed carve: 24" x 48". It works great for full Y travel, but when it gets to the last inch to the right of X it grinds.

So I home it per normal and then use the controller to manually send it to the right (X+). When it get's to the last inch, it acts like there is sand or something on the screw and makes a horrible noise. I back it up a few inches and try again - smoother the second time. Then i try a third and it moves great. 

If I re-home it, same exact, predictable behavior: Bad, better, gone. I have cleaned the guides, the screw and am out of options. 

Ideas? Thank you.

It sounds like the limit switch for the X travel is mis-located. This once happened for my Y switch. Try re-locating the switch a little to the left. If you move it too far left the grinding will happen on the opposite side. Adjust until there in no sound on either side.
The reason the sound disappears it that the motor loses steps each time it grinds against the limit of its travel. This does not actually clear the problem, as you have noticed when you re-set home.


Alternatively, check to see that you have the proper table size entered in the pendant for your table.

I don't think there are any MaxX or MaxY limit switches. I'm pretty sure they are controlled via the the max parameters in the controller. The table size may not be defined with the correct values.

It wouldn't be the first time I was wrong. Mine has limit switches. They are on the HOME XYZ limits. Once, I had to move the Y switch a little because the Y travel was hitting the end of travel and losing steps. (grinding noise)

First, thanks for all the input guys. I was on a long trip and was very eager to try your suggestions upon my return home.

I checked and the table size was correct. So I unscrewed the X drive carriage and moved it out from the head. It was caked with stuff so I cleaned it off. I ran it all the way to the right and it went fine. Then I pushed the head to the right and it glided right to the end. So I screwed it all back together and it works fine. Sometimes you get lucky.


PS- I did hear back from Chad at Axiom. He said that sometimes at the very end of travel there can be binding and what I did essentially re-aligned the drive with the carriage. So it was exactly the right thing to do.

Not "lucky", but persistent.
Thank you for updating us with the solution.

It seems like you're encountering issues with your CNC machine when carving a full-bed project, specifically with the X-axis movement towards the right side. The machine experiences grinding and makes a horrible noise, particularly in the last inch of travel. Despite cleaning the guides and screws, the problem persists. This issue could be attributed to various factors, including mechanical wear, misalignment, or debris accumulation. I recommend thoroughly inspecting the X-axis components for any signs of damage or obstruction, ensuring that all parts are properly lubricated and aligned. Additionally, consider adjusting the tension on the X-axis belt or checking for any loose connections. If the problem persists, contacting Monport's customer support for further assistance and troubleshooting guidance would be advisable. Given Monport's reputation for manufacturing high-quality and reliable laser products, their support team should be able to offer valuable insights and help resolve the issue with your CNC machine. monportlaser.com/collections/co2-laser-engravers/products/monport-40w-lightburn-ready-12-x-8-co2-laser-engraver-cutter-with-fda-approval?sca_ref=5031521.ka374VZjm3

Well, this isn't a Monport machine or problem. And it doesn't use belts. As a matter of fact, when visiting the monport site as suggested in other posts, it has quite a few adds and tracking cookies so...don't know how this is relevant to my post.

It has nothing to do with your post or 120+ reply that he (or it) made to other posts a few days ago. Best I can tell it is some kind of AI or bot of some type. I sent a PM to it after about 30 posts on less than an hour. Basically the same post in all of them with the same non-working link. There has been 2 major bombardments in the last few days. Hopefully one of the admins found a way to lock it out.
