Have owned the Glowforge for almost a year now. It has been working excellent with just a few simple issue we have been able to troubleshoot ourselves. However, we have a strange issue, that may not actually be the Glowforge, but maybe an interface issue. We have the Glowforge connected to a HP laptop, all WiFi. We have had zero issues and it has been in this configuration since we took the Glowgforge out of the box. Over the past couple of months, the countdown time in the GUI does not keep pace with the Glowforge. For example, if we send a project to the Glowforge that says it will take 18 minutes to cut, the GF will cut the project, return to the home position and go into the power mode (lights dim, fan speed reduces, etc.). The project turns out just fine, but the GUI may still show 3, 4, 6 (not these exact times) random time remaining. We thought this was a cleanliness issue, so we did a deep clean of the GF, making it sparkle like new. However, the first cut after the cleaning, the GUI countdown, time remaining was off again. We have made sure we updated our computer software and drivers, accepted any and all Microsoft Updates, but this has not solved the issue.
