Ultimaker 2 with 35W heater cartridge

Recommended Posts

Posted · Ultimaker 2 with 35W heater cartridge

Hey everybody,

this week my heater cartridge of my UM2 needed to be replaced because of a broken cable. So I ordered a new one labeled "Only compatible with the Ultimaker 2 family". After I replaced the cartridge the temperature of my UMO2 overshoots and oscillates in a range of +/- 10 °C.

I noticed that there is only one version with 35W available. The original Ultimaker 2 without the extrusion upgrade was shipped with a 25W cartridge. So I took the PID values from the UM2+ which uses the 35W cartridge -> No Problems.

 

M301 P10.03 I1.5 D70.00M500

 

It would be nice to have an option in the settings menu for selecting the cartridge version.

So did I something wrong or is that the normal behavior with a 35W cartridge? I didn't find the old 25W version

Well that certainly should be clear when you buy a 35W heater. Specially if inly says Ultimaker 2 Family.

Indeed your changes where perfect if the heater is 35W. Oficial firmware doesn't allow you to change pid of the heater, but @tinkergnome firmware does. Is much more flexible and it allows you to even change the esteps if you ever need it (along with some pretty useful options).

Also @sandervg maybe the heaters are being mislabeled? Because it could be slightly problematic for novice users I think. Just my 2 cents.

Anyhow you fixed your issue perfectly @jofleck

Perfect :)Then I´m not worried while printing :)

And thats the problem. The heaters aren't labeled as a 35W heater. In the moment I haven´t a use case for a more powerful heater. I don't care about waiting a few seconds longer for heating up. I just wanted a replacement which works out of the box and I think many other users too :).

I don't think they are mislabeled, but maybe they should come with clearer instructions. I'll double check and see if and where they can be included. Thanks for notifying us!

For the reference. My current PID values on UM2 (Tinker firmware) before upgrading from 25W heater to 35W one:

P10.00 I2.50 D100.00

They can me be viewed using M503 command.

Maybe we should port the UM3 PID controller to the UM2? It has a few extra features that greatly assist in stability of the temperature control. Then we might be able to find a parameter set that works for both the 25W and 35W.
