You’re halfway through a case. The patient is waiting. Everything seems fine — until your chairside system stalls. Nothing responds. You force a restart, again.

It’s frustrating, but also common. Across clinics, many dentists and technicians report chairside system “freezes” that interrupt treatment and kill productivity. Surprisingly, these issues often aren’t caused by faulty software or outdated machines. Instead, they come down to a few simple but overlooked system settings.

Here’s what might actually be going wrong — and what you can do to fix it.

Your Network Isn’t as Stable as You Think

Even if you’re not scanning online or using cloud storage, your scanner, design software, and milling unit still rely on a local network to communicate. And when that connection isn’t stable, everything slows down — or breaks.

What often goes unnoticed is that Wi-Fi dropouts, especially in multi-room clinics or buildings with poor signal coverage, can cause random crashes or data interruptions. Files might stop halfway during transfer. Milling jobs may disappear from the queue. Some users report delays that happen only at certain times of day — usually when other devices in the clinic compete for bandwidth.

If you’re using a SOREAL chairside setup with UP3D devices, they support both wired and wireless connections. But for best results:

Use direct Ethernet cables between scanner, PC, and milling machine when possible.

If using Wi-Fi, assign static IP addresses to avoid conflicts.

Make sure all components are running on the same network band (don’t mix 2.4GHz and 5GHz for critical devices).

File Format Conflicts Could Be Slowing You Down

Many modern scanners export in multiple formats — STL, PLY, or OBJ. But your design software might not be equally happy with all of them.

For instance, a color PLY file that’s too large can choke a system with low memory. Or a mesh that wasn’t fully closed during scanning might crash the margin detection tool in your CAD software. In some cases, the software might misread the data entirely, causing auto-recognition to fail or default to the wrong restoration type.

If you’re using UP3D’s own workflow — say, a UP610 scanner paired with UPCAD and the P42 PLUS — you won’t run into these issues. The data pipeline is consistent, and everything is designed to speak the same “language.” But in mixed setups, it’s important to check your output settings.

To avoid issues:

Confirm the file format your scanner is set to export — and make sure it aligns with your CAD system’s supported inputs.

Keep file sizes manageable by trimming unnecessary scan areas.

Double-check mesh integrity before entering design.

A single corrupted file can bring the entire workflow to a halt — often without a clear error message.

Smart Features Can Misfire if Left Untuned

Software with “smart” features — automatic jaw detection, case-type recognition, or auto-orientation — can be incredibly helpful. But they’re not flawless.

Sometimes, a scan taken from a slightly wrong angle tricks the system into thinking you’re working on a different jaw. Or the software auto-classifies a posterior case as an anterior one, assigning the wrong design strategy. These errors may not be obvious at first — until your milling result turns out unusable.

That’s why it's important to occasionally review and recalibrate your automation settings.

In UPCAD, for example, you can adjust how sensitive the system is to model type detection. You can also pre-set your preferred default case types to avoid misclassification. And with the latest firmware on 610 scanners, improvements in AI-based recognition help avoid scanning reversals and mid-case confusion.

The takeaway? Smart tools are great, but only if you stay smarter than they are.

It’s Not Always a Hardware Problem

When a chairside workflow keeps freezing, it’s easy to blame the machine. But more often than not, the issue lies in something much smaller: a network hiccup, a mismatched file, or a misunderstood automation setting.

The good news? All of these are fixable. And if you’re using a fully integrated chairside system — like UP3D’s SOREAL solution — many of these risks are already designed out of the process.

If your chairside system still stalls, don’t guess. Start with the basics. Check your connections. Review your files. Adjust your settings. The solution might be one click away.
