I have a question regarding stepper motor wiring:
People suggest to use shielded cable and that it should go to ground on one side.
But where and how shall i ground the cable shields on the duet wifi?
Using shielded cable without ground doesn't bring any advantage or?
I assume the magnetic field caused by the stepper motor current will induce voltage into the cable shield. But there is no way current can flow.
See http://reprappro.com/documentation/ormerod-2/wiring/#Fitting_the_cover_and_wire_routing for how RepRapPro did it.
This is nice as you see what it could look like.

And its description:
"All the wiring looms use shielded cable, to reduce the effects of Electro-Magnetic Interference (EMI). It is important that the shielding makes contact with ground, by earthing them through the metal case. Each wire has a slot in the case; bend each cable so it sits in the slot. Make sure that there is not sideways pressure on the housings, where they are plugged onto the pins of the Duet; they can loose their contact with the pin, and make a faulty connection."
Sorry for not making myself clear.
According to the wiki page printing in relative coordinates is more accurate, as errors don't accumulate. So using M82 is not recommended I suppose?
Is this effect even recognizable compared to absolute positioning EDIT: extrusion?
Found a confusing wiki page: https://duet3d.com/wiki/Slicing_recommendations
MatterControl and Cura don't support relative coordinates: https://www.duet3d.com/forum/thread.php?id=953#p9446
So the only free slicer to support it is Slic3r??
This question is important to me, because I need accurate prints.
@tape: Do you mean "update from 1.19 beta"? Please check if all the firmware versions are correct or just try flashing Firmware/Server again.
My question:
In standalone access point mode (M589 S"DuetWifi" P"Silverspoon" I192.168.1.1 –> M552 S2) I can connect to the DuetWifi.
DHCP works as I get an IP adress but "ping 192.168.1.1" leads to "Destination Host Unreachable".
So I don't have access to the web interface. However the Web Control was accessible before when connecting to a known network (mode M552 S1).
See http://reprappro.com/documentation/ormerod-2/wiring/#Fitting_the_cover_and_wire_routing for how RepRapPro did it.

Here is another thread regarding a similar issue, unfortunately unsolved:

But pinging should usually work nevertheless. This is quite strange.
Apparently this is not a problem many people observe…
As the wifi server is not crashing what could cause the upload to stop?
@thomasf: What's your signal strength? Do you have the problem since the beginning?
I created a thread in the firmware wishlist section of the forum about adding G2/G3:
https://www.duet3d.com/forum/thread.php?id=755
I believe CNC GCodes more often contain G2/G3 commands so to widen the applicability of RepRapFirmware this would be good to add. Also there is a bit of chicken and egg. If no firmware supports it then why bother implementing it in a slicer.
Like T3P3Tony pointed out, it would be a first step towards making .stl a thing of the past.

This will help on our way towards .amf support and to get more accurate hole dimensions:
