@dc42 . on the latest build G30 S-1 does not flash a value anymore. Is this a change that i missed?

ahh. i read that as the threshold of demagnetization. im glad to hear that it can run hot and not break. Thanks!!!

@X4TEC:

I've just been experimenting with sending the S3D output to the Duet Web Control using the rr_upload api. Its a work in progress and what I'd love to be able to do is upload to job to the SDcard via DWC from S3D, then see the job in the live preview, but not sure it will work that way.

I'm on windows so I installed CURL, then you added the following to the additional terminal post processing section of the S3D profile.

curl -d "@[output_filepath]" -X POST http://xxx.xxx.xxx.xxx/rr_upload?name=gcodes\S3D

I've just got it to work so may not be the final script. Ideally I'd like to store the upload with the model name, but I've not found the S3D attribute to send instead of "\S3D"

i believe you can get the file name using:

[output_filepath] = the full path to the file being saved, including extension
[output_dir] = full path to the folder that you're saving the file in (excluding the actual file itself)
[otuput_filename] = filename without extension or path

Hi,

My extruder motors (https://images-na.ssl-images-amazon.com/images/I/81rKW7OedjL.pdf) are running really warm (55d C) during an avg. print (2hrs). Here is the Config that im using currently:

; Drives
M569 P0 S1 ; Drive 0 goes backwards
M569 P1 S1 ; Drive 1 goes forwards
M569 P2 S0 ; Drive 2 goes backwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S1 ; Drive 4 goes forwards
M350 X16 Y16 Z16 E16:16 I1 ; Configure microstepping with interpolation
M92 X100 Y100 Z400 E399.54:409.35 ; Set steps per mm
M566 X900 Y900 Z12 E120:120 ; Set maximum instantaneous speed changes (mm/min)
M203 X6000 Y6000 Z180 E1200:1200 ; Set maximum speeds (mm/min)
M201 X500 Y500 Z250 E250:250 ; Set accelerations (mm/s^2)
M906 X1000 Y1000 Z1000 E400:400 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

Do you have any idea of why they would be running so hot? Given that the stepper is rated at .4 Amps, should it be set to lower than 400mA in the config?

Thanks in advance!

Can this also be added when the print is cancelled? it would really be amazing during calibration tests.

@T3P3Tony:

If it is a conventional MK2a (ie the one I adapted from Prusa's original design years ago), with a resistance of 1Ohm then at 12V it will draw 12A which is fine for directly being driven from the Duet.

That is assuming your power supply can happly provide 12A for the bed+the power for your heaters, fans etc. It may be that D-Bot power specifications work on the idea of having two power supplies one for the bed and one for the heater, in which case look at their capabilities.

If the heated bed you have is not 1A, specifically if it is going to draw more than 15A then you should use the DC SSR (but make sure you follow the guidance here: https://duet3d.com/wiki/Connecting_a_bed_heater#Bed_heater_driven_using_a_Solid_State_Relay))

Ive noticed this topic come up a few times, and the documentation referenced does not mention anything about Mosfet expansion boards like the MKS-Mos or BIQU boards (https://www.amazon.com/BIQU-Power-Module-Expansion-Printer/dp/B01HEQVQAK) .

Can you comment on why this would not be an alternative to the SSR listed in the Duet3D Documentation?

Hi,

I dont know if this is the right place to pose this question – I would like to figure out the best way to remotely Turn On/Off the Duet Wifi.

I have a Raspberry Pi 3 that will be part of the overall system that I would like to use to Toggle my printer to turn on/off. I can either run it off a separate 110V transformer or use the 12V Powersupply (350w Meanwell) using a Buck transformer to 5v.

My thought was to wire the Raspberry Pi to the 12V power supply (via the Buck Transformer) and then use the GPIO rail on the Pi to trigger the Duet from Standby to Fully energized.

Is this the doable, Or the right way? Should I run the 12V supply to the Duet through a SSR (like the Heatbed) via the Pi?

Anyone have any good ideas?
