Firmware 2.02 released!

As promised
, a 3mm radius corner, with two facets properly visible.

Rather than making the upper limit configurable, I think it better to make it speed-dependent. The reason I made it radius-dependent in the first place is that users complained that in 3D printer mode, the maximum speed achievable for G2/G3 commands was too low. But speeds are much lower in CNC machines anyway, so I could leave the segment length at 0.1mm unless the requested speed requires a longer segment and the radius allows that without losing much accuracy.

@dc42 Sounds better! But it is important to know the threshold speed value. While roughing apparently is done at higher speed than finishing, it depends on many factors and it may be actually done at lower speeds (bulk material removal requires a lot more torque than just shaving off a thin layer). 4000mm/s is a reasonable upper limit for 0.1mm/s, if possible. The WorkBee that I have is capable of 2500mm/s, and it's not that rare that I need to set feed rates close to the top limit. If using larger cutters I would have to go faster, just that I know that the machine is not rigid enough for the associated torques and thus I don't go beyond a certain diameter.

DIY CNCs usually rely on lowest cost motion solutions - that is stepper. Considering a 300rpm limit for the stepper while still having meaningful torque, combined with the usual 1610 lead screw (16mm thick screw, 10mm lead), that gives 3000mm/min feed rate. That is why I consider 4000mm/min a reasonable limit for CNCs that use steppers rated for up to 3A. CNCs that use belts are imprecise at higher speeds because of the belts flexibility and the ones that use screws and can go faster have much larger steppers, impossible to use with the Duet 2.

Or make different rules depending on the controller mode if the threshold speed is too low - no more than or fixed at 0.1mm for CNC (whatever was before) and new algorithm for 3D printing.

@dc42 have you stopped supporting DUETWIFI or something? I can't find any new firmware on that board, all firmware switched to DUET2WIFI, which is basically the same board, but the problem is that firmware won't install on DUETWIFI. Needless to say, that there is of course zero instructions about that.

@vlad the duetwifi and duwt2wifi are one in the same.

Instructions for updating are the same.

@phaedrux Thanks. Only if it was mentioned anywhere, as the firmware has different name and won't install, unless you rename it, which I did.

I guess you didn't read https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Upgrading_a_Duet_2_WiFi_or_Ethernet_to_firmware_1_21_or_later_from_1_20_or_earlier.

@dc42 I figured that out on my own already. Not easy to find a documentation in your holly mess here David lol. I haven't seen such a mess since I saw my room when I was a kid. Impossible to find any required info. You should check adafruit website as a good example of how documentation should be organized. P.S: my board has failed, so I guess I won't need anything for a while.

dc42

And you should learn to use the search facility. Duet+RRF is 100x more complicated than anything Adafriot sells.

M291 no longer allows S0 and T0 together because that would create a message that can never time out of be dismissed

@dc42

I used it as follows

M291 P"Nozzle is heated" R"Loading Support" S0 T0

G10 S230; TEMP

G28

G1 X125. Y10. F6000

M116 H1:2 S3
M292 ; Hide the message
......

I see now no way to implement the equivalent after the change.

Maybe we could create a new mode that includes:

not blocking
Only with the "Cancel" button, to cancel the current process.

That would have been missing before me, because if there is a mistake (for example, unintentional confirm) was the one zigste way to end this with an emergency stop.

What do the other people mean?

Thx very much for the release sadly I got massive wifi connection issues with this release.
Sometimes 2/10 I would say, I'm loosing connection during the print.

But I'm loosing always connection when idle for some time. I thought this firmware release fixed the reconnect issue?

Any ideas how to get around this?

Why don't you just set a long timeout instead of no timeout? Or allow it to be dismissed?
