Sometimes that is the best thing to do.

I had three deltas and decided I didn't like them - gave two away, trashed the third.

@imrj said in Adding wifi to a duet 3:

well on the duet2 i swapped a wifi to ethernet and also the reserved (added wifi to Eth) and it worked just fine in both cases, you will just need to give up that SPI port I think , just use a decent wifi module like ESP12 with some external antenna and give it a shot, unless they went as far to the effort of removing wifi support native from RRF3

both wifi and ethernet use the same spi port on the duet2 - but the wifi also needs an uart++. the support isn't removed from rrf3 as such, just not enabled when built for the duet3. its probably doable, but not as easy as with the duet2 as the ethernet is part of the pcb, not a module like the duet2 (and you need to change some of the sources for the duet3 part of rrf3 and build custom firmware)

Sensorless homing is accurate to three or four full steps. Works great for things where the last tenth of a millimeter doesn't really matter, like X and Y on a 3D printer. You'll find that printers that stall detect x and y still have a probe for Z.

This would probably be OK for a laser X and Y in terms of being in one corner of the bed, etc. Probably not accurate enough for Z (focus) repeatability.

It would NOT work for, say, a home, cut, home, engrave sequence. Or a multi-pass cut that had home in between. It would work fine for a cut then engrave without a home inbetween, or a multi pass cut without a home.

So, it depends just a little bit on how you intend to use it.
