¶ Resolving Chamber Heater Malfunction
This guide will help you troubleshoot and resolve issues related to the malfunctioning of the chamber heater in the Vision Miner 22 IDEX 3D printer. Follow the steps outlined below to diagnose and fix the problem. If the issue persists, please contact our support team.
¶ Step-by-Step Instructions
¶ 1. Set Temperature Manually via Web Interface
Access the Web Interface:
- At the top part of any tab, find the largest section l`beled Tools. At the bottom find Chamber line with two dropdowns.
Set Temperatures:
- Set both the Active and Standby temperature dropdowns to 70 degrees Celsius.
Observe the Temperature Graph:
- Check the right part of the screen for the linear graph.
- Verify if the "Chamber" line is increasing.
If the Chamber Line Increases:
- The issue might be with the slised file.
If the Chamber Line Does Not Increase:
- Proceed with the following hardware checks.
Safety Precautions
- Always ensure the printer is powered off and unplugged before performing any hardware checks or replacements.
- Handle electrical components with care to avoid damage or injury.
¶ 2. Hardware Check
Inspect Signal Wire Connection:
- Open the right rear door of the printer.
- Ensure the signal wire is securely connected to the circuit board (see picture below).
Verify Relay Functionality
Check Relay LED:
- While the chamber heater is supposed to be enabled, observe if the LED on the relay is lit (see picture above).
If the LED Is Not Lit:
- The relay needs to be replaced.
If the LED Is Lit:
- Proceed to check the heater itself.
¶ 3. Heater Resistance Check
Power Off the Printer:
- Turn off the printer and disconnect the power cord from the socket.
Disconnect Heater Wire:
- Disconnect one of the bed heater wires from the relay (see picture below).
Measure Heater Resistance:
- Use a multimeter set to the resistance measurement option.
- Measure the resistance of the heater.
Expected Resistance:
- A functioning heater should show a resistance between 50 to 60 Ohms. If the resistance is out of range the heater needs to be replaced.
¶ Troubleshooting Tips
- If the problem persists after following the above steps, it might be indicative of a deeper hardware issue.
- Contact our support team for assistance if you need to replace any parts or have further questions.
