Limit Stop and Soft Stop MPC6515 and LaserCut5.3

[JHamilton]

I have purchased a complete set of laser engraving machine from a Chinese company and I have been setting up the machine for a month. I am now trying to engrave a sample text on a paper to see if the machine works properly and I have a problem the machine always return as an error message "Soft Stop" or "Limit Stop"with a series of beeps. I read a similar posting here but my problem seems to be different. The working area of the machin is 60cm x 40cm, and the letter I am trying to engrave is just three letters "cat" which is about 1cm x 2cm.

First of all, the laser head doesn't move at all when it is in the original position which is the upper right hand corner, and then "Soft Stop" or "Limit Stop" sign comes out immediately with a series of beeps.

When I preliminarily move the laser head to the center of the working area before I operate Laser Cut software, the head moves for few seconds and it goes to the light to left edge of the working area and it stops working and "Soft Stop" or "Limit Stop" error come out with a series of beeps in the machine display.

And also it doesn't engrave a paper at at all. I confirmed there is laser coming out from the focus lens when I adjusted ray path, but when the laser head is moving the laser doesn't seem to come out from the lens.

It is just three letters but it seems the laser head is overlapping the actual working width; however I know "cat" is only 1cm x 2cm. Are there any other part of the software I need to change parameters or is this machine defective?

Does anyone know what is going on with my new machine? I highly appreciate it if you would help me fix the machine to make it work properly. If any other information will be needed for finding out the issue, I will post a new message accordingly.

Hi bro, base on your description I think it is software setting problem.
Did you install laser software by yourself?After installed software did you config laser machine?Before you using this new maching you must set the table area otherwise the laser head will keeping move towards start point which local out of your table area so the error message will come out.

After the laser has been turned on and it is ready to operate, hit the "reset" button on the laser control panel. I think that may solve your problem.

There is no reset button on the control panel of my laser machine. There are datum, laser, stop, test, start/pause, esc, and menu. Did you mean to hit the esc button?

Yes, I did install the software by myself. I looked at the parameter of the software. The working area size is adjusted properly height 40cm and width 60cm which is the actual working area of the machine.

Try the Datum button on the laser not the computer.

In LaserCut, in the download window where you click "Download Current" to send the file to the laser, there's also a button that says "Download Config". If your settings are correct in the software, maybe they've never been sent to the laser machine. That's what the download config button does, it sends the settings to the laser controller.

Could that be your problem?

Is there a SCAN button on your laser machine control panel?If yes, turn it off before you open your LaserCut5.3.then go to OUTPUT(one printer icon) click CANCEL, turn on SCAN button, use arrow key on control panel to move laser head.Try it and good luck :-)

For the laser output problem,you sure there is laser come out form laser head?If laser head dirt,it also not work.If you confirm laser won't come out only when laser head is moving,then you may try slow down the engraving speed and add up laser output power

Hello. Thank you for your reply. Today I tried the Datum button before I start operating the software and also just in case before clicking on the start button, but the "limit stop" error popped up immediately.

Hello. Thank you for your reply. I click on both "Download Current" and "Download Config" before clicking on the start button. When I click on "Download Config", I hear my machine beep and on the display of my machine, I can confirm the file name I downloaded. I think the file is downloaded properly.

Hello. Thank you for your reply. Unfortunately, there is no scan button on my machine. The buttons I can find are datum, laser, stop, test, start/pause, esc, menu, and also arrow keys and enter. I looked for a scan button under the menu button, but there were no such function I can find. For the laser output problem, I will try to use the higher power, but right now the laser head travel issue is more serious problem. It never moves when the head is at the original right hand corner. I wonder how I can fix this. I have been struggling on this for all day.

Hi..
In all lasers there is a place in configuration to set whether the software
does the stopping and monitoring of where the laser is, or it is done with
a mechanical switch that is activated at zero. Its possible that in shipping something has been knocked out of line and the software is not seeing
an absoluter zero so it is confused as to which direction to go. Look in
your menu and see if soft stop is enable or a mechanical sw. Its very possible that 1 to 2 cm may be too small an increment for a mechanical switch and
you need to be on soft stop. Thats the best I can do without actually
seeing the machine...I hope this is of some help.
