Carriage plate belt

so my carriage belt seems very loose and I’ve tightened the tension as much as i can .
having some issues with my engraves looking fuzzy and would like to replace the belt but i don’t see on the glowforge site a place to purchase it . so my questioned is , where can i purchase a the belt from ? thank you in advance for your help .

Belts aren’t available OTC yet, but by posting here you’ve let them know that you’d like one. They’ll close this post and contact you via email since you’ll be discussing personal address info etc. If your machine is still under warranty it’ll likely be covered, but if not they’ll send you an invoice. It will take a week or so between waiting for their response, and then waiting for the invoice to be generated, to getting it in the mail, so prep yourself for that :slight_smile:


You can shorten the carriage plate belt where it attaches to the carriage plate.

Replacing the belt would be the exact same process as shortening the one you already have, so it’s worth a shot.


Belts should not stretch. They are fiberglass or Kevlar reinforced and should last many years without an identifiable increase in length. If yours has stretched, you have damage somewhere. If it is loose, you may have a pulley that isn’t tight.

My Glowforge is more than two years old and has no stretch in its belts. You should look for something else that is causing the issue.

my pully is as tight as it can get and belt is still loose . but i will look at other areas to see if there is any other damage thank you for your help

Oh no, I’m sorry to hear about the trouble!

To better understand, would you send me the following photos:

1. The belt under your laser arm with the head pushed to the left:

2. The pulley under the laser arm on the right side from the front:

3. The right side pulley under the laser arm from underneath:

This will help us determine whether or not you need replacement parts.​


so I decided to take your suggestion and shorten the belt . i only cut about a half inch off which is about the size that fits in the clamping area . and it worked great . i was very hesitant but since i wasn’t cutting that much off i felt i had nothing to lose at this point . and it worked perfectly ty very much for your response and giving me the idea to try this , it was such a simple fix .
