Board selection (RoHS, no wifi, 5x, g-code at startup, REACH?)?
-
Hi,
I'm new to this board, could someone please help me confirm whether Duet boards fulfill the following requirements? If yes, which board versions in particular would be suitable? I believe "Duet 2 Ethernet", "Duet 2 Maestro" and "Duet 3 6HC" would work, but maybe I've missed something.
Thanks a lot

RoHS compliant: I've seen threads about that (like here), but I have not found official certificates. Is there one somewhere or should we contact resellers privately?
-
I believe that there is no need for costly Electromagnetic Compatibility/Interference (EMC/EMi) testing in the boards "Duet 2 Ethernet", "Duet 2 Maestro" and "Duet 3 6HC" because they simply do not have a wifi module, correct? These boards are then not considered as intentional emitters.

independent simultaneous control of 5 stepper motors with g-code
-
automatic execution of g-code upon startup (no button press needed). Can the g-code be preloaded in the board or in the SD card? It seems to be possible, by writing commands at the end of config.g as mentioned here?
-
Is there any information about the REACH compliance of these boards, that is, is there a certificate stating that they do not contain any SVHC (substance of very high concern)?

@yurk_12 email info@duet3d.com and we can provide ROHS certificates. REACH does not apply to finished PCBs AFAIK. All substances are contained within the PCB and components so ROHS applies.
The Ethernet versions of the boards contain no intentional emitters
Yes you can control more that 5 steppers independently on all versions of the duet 2 and duet 3.
Gcode can be stored as macro files or as prints/jobs on the SD card. Those files.can be called from the startup gcode, although it makes sense to think carefully of that is a good idea.

@t3p3tony Excellent, thanks a lot for your answer. I'll send an email then.
I agree with you on being careful with the startup code.
