Comes with firmware loaded, you will want to upgrade to the latest version which is drag and drop through the UI. No need to compile anything or install IDE to set it up.

P.s. forum.duet3d.com is the best please for support questions.

Hi Richard

Fair comments, the issue is exactly as you say. IR reflection is not listed for filaments. We only have what tests we, and our very helpful community have done. Generally ABSs tend to work well. PLAs work well to acceptable and PETGs work poorly with a few exceptions like e3d edge that is just about acceptable. There are so many variations in filament additives, let alone plastic types that it would require a dedicated team to test and qualify all of them.

Cheers

Tony

Daniel do you mind adding this to the the forum in the firmware wishlist category:

https://forum.duet3d.com/category/8/firm...

That will help get other people to comment which helps us understand how poipular it is as a requirement for prioritisation.

Hi Chris. please use our forum forum.duet3d.com for support.

The forum allows for a much better way of giving advice to specific problems. Comments here much more cumbersome to handle.

please discuss this on the forum.

The SX1509B is only for relatively slowly changing signals. it is not appropriate for stepper drivers. if you need that level of Expansion then use the Duet 2 Wifi or Duet 2 Ethernet.

Hi David

I have updated the picture to show an appropriate tool for dupont/Molex KKs - thanks

Hi Lucas, thanks for the comment. We use an Ethernet jack with isolation transformers so ground loops should not be a problem.

Thanks (and to Bill McDaniel, missed that one)

Updated the first step to state what ferrules we supply.

The wire gauge chosen will depend to a large part on the current being drawn, especially for the heaters which often dominate total current.
