Max Chamber Temp Pulsar?

[Alex LaVelle]

Hi,

What is the max rated chamber temp for a Pulsar? 

[Technical Support]

Hi Alex,

The maximum rated chamber temperature for the Pulsar is 60°C.

We advise against exceeding this limit, as most of the internal connectors are not designed to handle temperatures higher than this.

Can you clarify on the “internal connectors”? I’d imagine anything touching the main barrel would be far beyond 60C during printing so I assume you mean the primary wiring connectors? I need to run the Pulsar in a 70-100C chamber so I’ll need to make modifications to the Pulsar. Knowing what parts you’re talking about would be helpful.

Hi Alex,

To clarify, the "internal connectors" we referred to are primarily the Molex Mega Fit, Molex Mini Fit, and Molex SL connectors located at the back of the heat zone. While these specific Molex connectors are rated for up to 95°C, the overall concern at higher chamber temperatures extends beyond just these connectors.

Inside a heated chamber, the temperature rise can critically affect the PCB and some of its components, including the soldering points, if the surrounding ambient temperature is too high. This is why we advise against exceeding 60°C for the entire unit.

If you intend to operate the Pulsar in a chamber ranging from 70-100°C, significant modifications would be necessary to ensure reliable operation and prevent damage. This would involve completely removing the stock PCB and connections, and replacing them. All wires would need to be properly soldered using high-temperature solder, and high-temperature rated wires should be used throughout.

Please also note that the PT100 sensor wires are very fragile, and extreme care should be taken when handling them during any modifications.

While we can offer assistance and guidance as much as possible, any modifications made to the Pulsar will void the product warranty, and the cost of replacing any broken parts would be at your own expense.
