Defective Zstop limit switch

Recommended Posts

We got set back months by the failed filament heater:


$50, for a $5 part, arg. We got gouged, and a long lead time, to boot. Now the Zstop limit switch was found to be defective by the Cura self test, and my multimeter reveals that it stays open circuit regardless of being pressed, unlike Xstop & Ystop.

We want so badly to make our first print! Does Ultimaker sell replacement parts (or even better, replace a part that was part of the original kit and doesn't work?). Or do we forage out on our own and get gouged again?

What is the fastest way we can get a replacement Zstop limit switch?

Thank you!

The absolute quickest way would probably be to head to your local electronics store, if you have one, and grab a switch from there. If not, get in contact with your local reseller and see if they have any in stock to send you. If they don't and have to order from Ultimaker first, I would order a switch online from one of the many electronics suppliers like Digikey etc (not sure where you're located).

That would be quicker than waiting for two shipping times so to speak. You'll have to de-solder the old switch from the wires and solder on the new one though.

Hi, Clark,

Since you've just built your printer, fbrc8 should be able to provide a Z-switch for you under warranty. Our office is closed for the weekend, but if you open a ticket at Support@fbrc8.com, we should be able to ship the part to you on Monday. We'll need your serial number, name and shipping address, and the name of the part you need (UMO+ Z-switch). Email in to Support@fbrc8.com. It may also be helpful for you to include the link to this thread. All of our parts in our webstore and for our warranty support are official parts direct from Ultimaker.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
