Hi My laser keeps cutting out after about 20mins. I have tried different angles and placing material in a different spot but it keeps happening. I get the following in the console
Target buffer size found
Thank you for your reply. I do have another power supply that a can change over. Iâm getting error 2, 8 and 9 limit switches everythingâs crunching!!! In your opinion do you think that could be related too?
I have the SculpfunS9 with the upgraded x axis bar with limit switches installed. Its been working fine for months now. I may have messed up my machine settings? how can i. show you screenshots Aaron? Thank you for your time
Your current $ values look like you either didnât adjust the settings when you made the upgrade, or they magically reverted to the defaults.
$22=0 means that the homing sequence isnât enabled.
Did this work after you made the upgrade?
We made this video explaining how to add limit switches to a Sculpfun laser:
$130, and $131=355 are the X- and Y-axis maximum travel distances. Youâll need to change the $131 value to the new extended distance and reflect those changes in the LightBurn Device Settings.
I am guessing all the other errors are centered around this one.
Here is some information that may be helpful.
Home - A machine physical location determined by limit switches. It cannot be moved (by physically relocating the switches) to any location other than one of the 4 corners. The controller may set this location to 0,0 for the Origin, but not always. Origin - A software or program location designated as the 0,0 location. The Origin can be anywhere within the machine frame. Moving the Origin requires a strong working knowledge of graphic coordinate systems. Lightburn requires operating in the First quadrant, where all locations are +X+Y values. G54 - A work coordinate offset, normally all zeroes. If any of the 3 positions (X, Y, or Z on that order) are non-Zero, then the numbers are algebraically added to the Origin numbers. This essentially moves the âworkingâ Origin to a new location.
I believe something to be wrong in here . the spindle attached to the motor makes hell of a noise when tavelling left. Any help gratefully received. Thanks
Aaron and Mike
Thank you both for all your help. I am now back up and running. I noticed that the spindle below the linear rail had worked loose, I tightened went through all your valuable information and the problem seems resolved. Thank tou both.
I read in your profile, that you upgraded from the 5W to the more power-hungry 10W module. If you used the same power supply for both, itâs it is entirely possible that this is the cause of the initial âConnection Lostâ problem.
If you see it again, do what Mikey suggested: Run the same job with 0% power to find out whether the power supply is at fault.
I may have misunderstood you here and thought you had installed the axis extension.
Disregard my previous comment about changing the âMax Travelâ if thatâs not the case.
