@tjb1: @Kerzal: @tjb1: I have modified the original design in KiCAD to fit 20x15 but have never had them made. I can share that with you tonight if you want to have someone like OSHPark make them. Wow, this sounds like exactly what I'm looking for! I would appreciate if you share this with me, no need to rush it tho, I'm a patient guy. This should be it - https://github.com/limited660/DuetSmartEffector15x20 Looks great! I've ordered 3 of them now, never ordered services like this before, so its exciting to see the result

More than 12 steppers won't be in next month's announcement; but we are working on it.

1. Yes there are people using RRF with no heaters. Why would a program for sending CNC GCode send M105? 2. You can configure the response of RRF to M0 by providing a stop.g file. If stop.g is provided, it doesn't turn the motors off.

It will be months rather than weeks.

Yes you lose a third of the DAC range initially; but you will need op amps to get the drive voltage range you need anyway, so you can get the range back at the expense of a slight loss of resolution (that's why I described the resolution as "almost 12 bits"). You didn't answer the question in my previous post. The answer to it is critical in determining whether an external DAC is a viable solution and what speed microcontroller you need to drive it.

How about using two flat CAT6 cables? One for low voltage stuff (temp sensor and Z probe) and one for heaters and fans? Mind the heater current doesn't exceed the cable rating.

When you’re dealing with high currents “simple” is a bit of a relative term. Resistance has a nasty habit of changing as things heat up. Admittedly it goes up for cheap copper heaters so a cold measurement would suffice for a safety check. Having said that, insulation is a bit of a relative term when dealing with cheap imports. DC is, of course, right though - current measurement is definitely a nice to have and almost certainly not worth the additional cost.

Nice to see somebody actually did it. Thanks, Kraegar! Good to know.

There isn't wiki page on getting a good WiFi connection at https://duet3d.com/wiki/WiFi_disconnections_and_AJAX_timeout_errors.

@dc42: The problem with that approach is that you can either mount the SD card as a removable drive, or the electronics can access files on it; but not both at the same time. Smoothieboard users sometimes get into a mess because they forget which mode it is in. Ah, I didn't noticed. It seams that I'm one of those users

We may change Erase to be a jumper on the next generation Duets. In the meantime, setting the Erase button further back as we do on 1.02 and later revision Duets has greatly reduced the risk of pressing it by accident.

Hi… Can post setup, in config.g of Nimble extruder? Thanks

@T3P3Tony: Fair enough I would be pretty surprised if anyone managed to make it fit on 2 layers. Also that would remove the ground plane which would be a bad idea. Would most likely mean just quite a "few" 0ohm resistors and a larger sized board (which isn't bad in terms of heat dissipation though).

Like I said, we're looking at alternative connectors for the next generation - the current Duets don't have enough space for anything else. I already have some samples of lever-operated terminal blocks, and we are evaluating XT30 connectors too. We're also considering the same type of screw terminals that most PSUs have.
