Thermal Runaway

in AXIS 3D Printer

The second power supply went out today. This is getting stupid. I cant believe the amount of things that are sub par on quality.

I had bought these as a replacement, but they dont have enough to power the heated bed. Does any one have an idea on what can be a better replacement? Thank you

The "solution" is to go with a Mean Well 300W power supply. It would be a small project. Most of them are sold as just the supply unit itself. You'd need to get the socket with toggle switch and fuse. Then build an enclosure or something to hold those bits and then run the wiring to the mainboard. You'd have to be comfortable with doing some soldering and electrical stuff. It's a project I had anticipated on taking up once I get the printer actually printing to a level that it's worth doing it.

These hot beds have a problem staying at 60°C The power supply just isnt made to do that. 50°C wasnt keeping the print on the bed.

Heated bed temp is limited to 55 degrees Celsius, at room temperature, on the Axis because of the power supply capability (96W). This should be enough for PLA. If you're finding you're having to go higher then it's likely that your nozzle for the first layer is too high. Going higher will put more strain on the PSU.

but from the website it says this.


Our heated bed is a high quality aluminium platform with an integrated copper heater trace. It reaches temperatures of up to 110 degrees Celsius and is controlled through a beefy external MOSFET.

The platform is powered by a dedicated independent 24V power supply.


So are you saying that you lied to sell me a product?

Funny how the website has now been upgraded to say the correct information.

but you can still find the offending one on the kickstarter.

When putting together the kickstarter the heated bed info was copied over from the Proforge 2S as they both run the same heated beds (identical spec). The heated bed itself is actually capable of running at 110 degrees.


The power supply for the heated bed needed to be the same as the one that runs the printer and in order to reach the buying power needed to purchase for the low cost Axis printer.


The heated bed was still tested with these power supplies and works well. If you're having trouble getting prints to stick it's likely that the first layer is not close enough to the print surface.


The description on the website has just been updated.
