Alignment off and not cutting all the way through


#1

So, ive been having issues for a while now, thought it would work itself out, but no such luck.
Firstly the alignment is of every try i make, ive cleaned the camera, rebooted but nothing works, also, mainly on proffgrade wood, it wont cut all the way through.

Given the fisheye lens, alignment is best right under the lens, and does shift as you get to the edges of the bed. But off more than 1/4" is an issue–there are many other threads about tests you can do and steps to take.

For cutting through, be sure the boards are flat, flat, flat against the crumb tray. Magnets and the awesome pins that are a free pattern help. But many woods can be in consistent due to knots, which are much denser & harder to cut through.

And if using a full PG board, I’ve found the overhang of the masking film can double up under the edge, or keep it from seating well, and need to trim it back.

You can try slowing the speed down a bit, as well as add a second pass. And I’ve learned to never remove pins or magnets until I know the cut is thru, as when it’s still in position, I can run another cut to get it clean & not worry about trying to realign it.

But I totally understand–somedays seems no problem and the next is nothing but second passes…

The software on your Glowforge is responsible for ensuring that the print lands on the material in the same place as the preview. When you’re done with a print, let a new image load. If the print appears on screen far from where it was supposed to go, you may have an alignment problem.

Most alignment problems come from the material being closer or farther from the camera than expected. While the software is still improving, you can take these steps for the most accurate alignment results:

  • Use Proofgrade™ materials.
  • If you don’t use Proofgrade materials, use a precision set of calipers to measure your material, and enter the thickness in the “uncertified materials” dialog.
  • Use material that is not warped or tilted.
  • Place your design near the center of the bed.
  • Clean the area underneath your crumb tray, particularly the four indentations on the floor.
  • Reboot the machine. Alignment can drift over time, particularly if you bump the head of your Glowforge while removing material.

We’d like to have you try a few troubleshooting steps for us:

  1. Turn off your Glowforge.
  2. Check for small pieces of debris or dust.
  • Check the lower door to make sure it closes all the way. It may require some force to open, but open it, wipe any dust off the edges, and close it all the way.
  • Remove the tray and clean any dust or debris from the surface underneath. Pay careful attention to remove all debris from the four dimples where the tray rests.
  • Check the lid to make sure it closes all the way. Small particles of material, such as dust or debris, can prevent it from closing completely.
  1. Check the surface your Glowforge is on to make sure it’s flat. Ensure it is not twisted slightly and that there is no debris propping up one side of the machine.
  2. Turn your Glowforge back on.
  3. We included an extra piece of Proofgrade Draftboard with your materials shipment for troubleshooting. Place the Proofgrade Draftboard on the far side of the bed and print the Gift of Good Measure using the default settings.
  4. When the print finishes, leave the lid closed and wait until the fans stop and the picture updates. Without moving your artwork or your material, take a screenshot of the Workspace to show us the difference between the artwork placement and the actual print placement. Make sure to include the rulers in your screenshot and show as much of the bed as possible.
  • Mac: Press Shift-Command-4 and click and drag a box around your image. You’ll find the screenshot file saved on your desktop.
  • Windows: Click on the Start Menu and type “snipping tool”. Open the Snipping Tool > New then click and drag a box around your image. Click the Save icon and name and save your file.
  1. Send us the screenshot along with the date and time of the print, and we’ll investigate.

Should you finish all of these steps, and find that you have an alignment error of more than 1/4", please contact us so we can investigate.

It’s been a little while since I’ve seen any replies on this thread so I’m going to close it. If you still need help with this please either start a new thread or email support@glowforge.com.
