Duet WiFi firmware new feature priorities
-
Yes, there is a Z parameter in the G10 command that defines the tool offsets. You can define whatever parking moves you want in the tool change gcode files.
-
I was not aware of tool change gcodes… this is fascinating. The more I use RRF, the more I am impressed by its capability.
Does the mere existence of T0.g, T1.g, etc, allow for their execution upon tool selection?
-
They are called tpree0.g, tpost0.g and tfree0.g for tool 0, and similarly for the other tools. See https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Cartesian_printer#Tool_change_files.

Curious if there is a beta of the Grid leveling that can be tested
The grid levelling is more than 50% implemented in the 1.17dev5 release that is now on GitHub. You can define the grid using M557 and probe it using G29. Still to do is to finish the interpolation code, then add save/restore of the height map to file, and segment long moves. I may get time to do those next week.

Hi all,
I have not found a smooth way to have the heat bed cooled down in a controlled (following a temperature function) way.
Just switching the heatbed power off cools down to fast and results (from my opinion) on some filaments in warping on the print object.How about implement a firmware function to allow the heat bed cool down on a parameter like e.g. 3 ° Celsius per minute ?
The same feature would be useable for those having a heated chamber.What do you think ?
Regards

That feature could certainly be added. However, I haven't seen anyone else ask for it. OTOH a common complaint is that the bed cools down too slowly and a fan is needed to speed up the process.
What is the construction of the bed on your printer? Does it have insulation beneath it?
-
I use a 8 mm Aluminum heatbed with some temp isolation at the reverse side.
I notice that (depending on the filament) the edges are warping.
This warping may occurre during the print itself, or even when not happing during the print, it can happen after printing,
when the temp is falling too fast.
Currently I'm sitting beside the printer and do manually controll the bed temp in some steps downwards.
I have the impression this helps, may be others didn't try this, or have no warping issue at all with the filament.Not sure how much work it is to add this as a feature into the firmware.
How about having a macro that after print is completed, contains some timers with mapped temperatures ?
e.g.
Macro cool_down
timer 1: 5 minute (after Macro call) - bed temp 70 °
timer 2: 10 minute (after Macro call) - bed temp 60 °
timer 3: 15 minute (after Macro call) - bed temp 50 °
timer 4: 20 minute (after Macro call) - bed temp 40 °
timer 5: 25 minute (after Macro call) - bed temp 30 °
timer 6: 30 minute (after Macro call) - bed heater off -
I had no idea that the wish list was so long, what would we do without you.
Here are my priorities.O. Support for restore points. This would allow the print to be paused, a restore point created, and the printer shut down - either automatically because of power failure (although a UPS or SLA battery would be needed to power the printer for a few seconds), or manually. Then the printer could be re-started and the print continued from the same point. Only practical for 3D printers that can be re-homed when there is a print on the bed, or for which the motors can be relied upon to retain their positions if they are shut down at an appropriate full step position.
B. Multi-threaded web server, capable of supporting several concurrent connections even when one of them is uploading a file. May also increase the speed of file uploading a little.
J. Dynamically-varying microstepping, allowing true 256x microstepping at low speeds, with microstepping automatically reduced for faster moves.
M. Babystepping, i.e. ability to change where the printer thinks Z=0 is in small steps during a print.
C. Predictive temperature control. This will replace PID. Probably the main benefit is that it will have a simple and fast auto tune procedure. implemented in version 1.15 -
I might have missed it but did babystepping make it into one of the updates?
Also will grid levelling be available for delta as well as other kinematics?
Just read the grid levelling thread. -
Babystepping is still on the to-be-implemented list. Grid based bed compensation got more votes.
-
A filament tracking with encoder plug to an endstop pin can be my request on firmware wishlist !
-
What about adding an access point mode somehow?
For example if you want to travel with your Duet you don't need to reconfigure another WiFi connection.(Not with your smartphone, notebook or a foreign access point)When the Duet doesn't find the preconfigured WiFi there could be an additional access point mode option in the WiFi setup menu (192.168.1.1).

Can Enable auto sleep by turned on my default?
-

Please define what you mean by auto sleep.
Currently the default behaviour is that when all motors have been inactive for 30 seconds, the motor currents are reduced to 30% of normal. The timeout and percentage are configurable.

In another thread it was discussed to add an exception for trigger 0 so that it was prioritised over running macro events. Purpose being to have the ability to add a physical emergency stop using a micro switch
Is this possible? -

Is this possible?That's already coded in 1.17RC1, although I haven't tested it or measured the latency yet.
-
G. Support for three independently-controlled Z motors, normally moved in sync but moved independently when performing bed leveling (and I really do mean bed levelling, not bed compensation).
I just want to thank you for this being in a new feature list.
And i have a question if this is a proper thread. Is it possible to do a two side filament diameter measurement with live adjusting printing parameters depending on filament diameter? -

Possible in principle, but to do it accurately I think it would need two linear CCD sensors and probably lenses. Unless you are extruding your own filament, it's probably not worth while IMO because most filament has good diameter accuracy these days.

Yes, i want to use my own filament(From Filastruder 2) and yes, you get my bad English right, dual CCD sensors is what i want. Not a must have thing, but i think it will increase quality of my prints and make my printer more userfriendly.
I saw this, not my thing, i want dual sensor because filament may have an oval profile.
