AMS & Humidity Monitoring

Bambuddy provides comprehensive monitoring for your AMS (Automatic Material System) and AMS-HT (High Temperature) units.


AMS Slot Status

Each AMS slot displays:

Information Description
Filament color Visual color swatch
Material type PLA, PETG, ABS, ASA, etc.
Remaining Estimated filament left
Active Currently feeding indicator

Multi-AMS Support

Bambuddy supports multiple AMS units per printer:

  • Up to 4 AMS units (16 total slots)
  • Each unit displayed with its slots
  • Visual indication of active slot during printing

Humidity Monitoring

Track humidity levels inside your AMS units:

Current Reading

The humidity percentage is displayed on the printer card:

Level Status Action
< 20% Excellent None needed
20-40% Good None needed
40-60% Fair Consider drying
> 60% High Replace desiccant

Configurable Thresholds

Set custom warning thresholds in Settings:

  1. Go to Settings > General
  2. Find AMS Humidity Threshold
  3. Set your preferred warning level
  4. Save changes

Filament Sensitivity

Different filaments have different humidity sensitivities. PLA is more tolerant than Nylon or PETG.


Temperature Monitoring

For AMS-HT (High Temperature) units, temperature is also tracked:

Reading Description
Current temp Live temperature inside the unit
Target temp Configured drying temperature
Status Heating, holding, or idle

Historical Charts

Click on the humidity or temperature indicator to view historical data:

Time Ranges

  • 6 hours - Recent trends
  • 24 hours - Daily pattern
  • 48 hours - Extended view
  • 7 days - Weekly overview

Chart Features

  • Min/Max/Avg statistics
  • Threshold reference lines
  • Interactive tooltips
  • Zoom and pan

Data Retention

AMS data is stored for historical analysis:

Default Retention

  • 30 days of humidity/temperature data
  • Configurable in Settings

Configuring Retention

  1. Go to Settings > General
  2. Find AMS Data Retention
  3. Set number of days (1-365)
  4. Older data is automatically purged

Storage Impact

Longer retention periods increase database size. Consider your available storage.


AMS Notifications

Get notified about AMS conditions:

Available Alerts

Event Description
High Humidity When humidity exceeds threshold
Low Filament When filament is running low
AMS Error When AMS encounters issues

Setting Up

  1. Go to Settings > Notifications
  2. Add or edit a provider
  3. Enable AMS-related events
  4. Save changes

AMS-HT vs Standard AMS

Feature Standard AMS AMS-HT
Humidity monitoring
Temperature monitoring
Active drying
High-temp filaments

AMS-HT Temperature Control

AMS-HT units can actively dry filament:

  • Set target temperature in printer settings
  • Monitor heating status in Bambuddy
  • Track temperature over time

AMS Discovery

Bambuddy automatically discovers connected AMS units:

  • Detected during printer connection
  • Updates when AMS configuration changes
  • No manual configuration needed

Dual-Nozzle Wiring

For H2D and other dual-nozzle printers, Bambuddy displays the AMS wiring configuration:

  • Which AMS units feed which nozzle
  • Visual diagram of connections
  • Helps plan multi-material prints

Spoolman Integration

Sync AMS slots with Spoolman for complete filament tracking:

  1. Configure Spoolman integration in Settings
  2. AMS slots sync automatically
  3. Track usage across your inventory

Tips

Desiccant Maintenance

When humidity consistently stays high, it's time to replace or regenerate your desiccant packets.

Filament Storage

For filaments not in the AMS, store in vacuum bags with desiccant to maintain low humidity.

Historical Analysis

Review humidity charts to understand how your environment affects filament condition over time.

AMS-HT for Hygroscopic Filaments

Consider AMS-HT for moisture-sensitive materials like Nylon, PC, and PETG.
