After years of working with Glowforge, I feel compelled to address a recurring issue that continues to disrupt our workflow.
The machines randomly going offline — often at odd hours during the night — has become increasingly frequent. When this happens, the noise the Glowforge produces is extremely disruptive. The grinding and howling sounds when the system encounters an error are impossible to ignore, especially in the middle of the night.
What makes this even more frustrating is the lack of clear communication. A simple system-wide email notifying users of server or connectivity issues would resolve much of the confusion. Instead, users are left wondering whether the problem lies with their machine, their network, or Glowforge itself.
It is entirely possible for some machines to appear unaffected, given that Glowforge operates across multiple servers. However, when your specific machine loses connection, the experience is very real and very disruptive.
We have been using Glowforge machines for approximately seven years, and this issue has never truly been resolved — only tolerated.
Over time, we developed workarounds simply to maintain efficiency. One of those decisions was leaving our machines powered on 24/7. The centering process can be unnecessarily time-consuming, often requiring repeated adjustments using flashlights, shadows, restarts, material color changes, and multiple recalibrations.
Leaving the machines on became the most practical solution.
However, with three machines running continuously, the consequences of nighttime disconnects are significant. When a machine drops offline and attempts to reinitialize, the grinding and mechanical noise is loud enough to wake everyone in the house.
This happened again tonight.
Being forced to get up, shut down the machines, and then face the lengthy alignment process the following day is incredibly disruptive.
Why have we remained with Glowforge?
Primarily because, when paired with the external air filter, it has been one of the quieter systems available. Noise levels matter greatly in our working environment, and Glowforge offered a reasonable balance.
But with the number of alternatives now available — many offering local control, improved reliability, and more refined workflows — this ongoing instability is becoming increasingly difficult to justify.
Nothing creates stress quite like being woken up by the harsh grinding of a machine reacting to a connection failure.
Lately, this issue has been wearing thin.
