Connecting Duet Wifi to slicer software
-
Ok!!
More positive progress. First, I bought and installed Simplify3d, then I watched their introductory tutorials.
I am perfectly clear on the relationship between the Slicer and the DuetWifi and have a good solid process for loading my file, slicing it, and then using File Upload to SD.
I have the nozzle heater come up to temperature by starting it manually, and the bed come up to temperature also by manual input, and then I start seeing messages that I am trying to heat without a tool selected, and then trying to extrude without a tool selected.
In Simplify3d, I have the Extruder in Process1 set as Primary Extruder. In the Primary Extruder Toolhead, Index is set to Tool 0.
My start script is:
G21; Metric Values
M116; wait for all temps
M561
T0
M116
G28 ; home all axes
G32What am I missing to link the Primary Extruder in Simplify3d to tool0 in DuetWifi, or should it be something else?
I have a Titan Bowden Extruder that is E0 on the Wifi board. It seems that at the best of times, I am only getting a tiny little bit of filiment coming out of the nozzle, and sometimes none at all. I'm not sure if that is because of the tool error message or something related to steps / mm on the Titan Extruder. (where do I set that and to what value?)
In Simplify 3d, the diameter is set to 0,4, the extrusion multiplier is 1 and extrusion width is auto. I do know that the Titan extruder has a 3:1 ratio.
Should my extrusion multiplier be set to 3?
Making progress but not printing yet….
Thanks.

Have you set the extruder steps/mm value correctly, in the appropriate M92 command in config.g ?
-
I have not set an M92 command anywhere. I know pretty much 0 about g codes
Is there a document anywhere that explains how to setup Simplify3d with DuetWifi? I feel like I'm twisting in the wind.

Did you download the .fff file for the Tevo for S3D?
Try adding a M104 T0 to the top of the startup script.
M92 defines the number of steps of your motors. I found this for the Tevo.
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,1600,822}
Add M92 X80 Y80 Z1600 E822 to your config.g before your M906.
It would then be best to manually move each stepper motor in DWC 100 mm and check that it does move that far. With the extruder, mark the filament 150mm before it enters the motor, warm up the hotend, command 100mm movement at 1mm/sec (so it won't skip) and measure how far away the mark on the filament is now from the motor. Should be 50mm,

Hi number40fan
Thank you so much for your post with this level of detail. You are amazingly helpful and I really appreciate it. I will follow your outline and report back.
I am having some problems also with setting the initial Z height. It is too high.I will look for the .fff file for the Tevo for S3D

Hi number40fan
I downloaded the .fff Tevo file for S3d. It was for a dual extruder model, where mine is a single. I removed the 2nd extuder and the heater for it within Simplify3d and saved the profile.
I will modify the script to reflect your contribution above and then test my actual distances.
My configuration has the Titan extruder which they were including with the purchase of the printer. I mention it because from what I read, it changes the distance / mm from what the stock extruder would provide.
I will keep you posted.

Ok:
I was under the impression that the script file from Simplify3d would overwrite the bed / config files from DWC.
Here is my current script file:
M104
T0
M92 X80 Y80 Z1600 E822 ; define steps / mm configurations
G28 ; home all
G92 E0
G1 Z0.1 F1000
G1 X8.0 F2000
G1 Y60.0 E4.0 F1000.0 ; prime
G1 Y100.0 E8.5 F1000.0 ; prime
G92 E0When I uploaded the file to DWC, the printer ran what appears to be the autobed compensation file as I saw errors indicating that the Z probe had not triggered during the hot end's move.
Here is the home all content which is called from the Simplify3d script:

;G1 Z5 F100The hot end is still high and I am not getting much extrusion (if any), so I killed the print.
I am now going to go through the manual tests to measure the steps / mm settings that you referenced in your post.
Thanks,

Note
Sorry, I forgot to mention that I still get the messages indicating movement with no tools selected and then heating an extruder without a tool selected. -
Ok . Travel distances
X moved forward 100MM
Y moved forward 100MM
Z moved up 30MME made a lot of noise but did not move. Set the heater to 240 and clicked to unload filament. No unload.
Unlocked the plastic tube where it enters the hot end and removed it with the filament. Good solid 5mm length of filament at the end that was removed. Looks like the tube did not go all the way in, or something else is off in the hot end. I will take it apart, check the nozzle for a clog, and then check to make sure the metal tube is sitting against the back end of the nozzle before I put it back together.Nozzle is clogged.
Thanks,
Tim

Unclogged. I can manually push on the filament and it will flow out of the nozzle. I've played with the feedrate and amount settings and it doesn't seem to want to push it through.
If I manually get it started, it will feed for a bit, and then it will stop and the stepper just rocks back and forth, seemingly between forward and backward. Any chance it need more current to turn the motor against the backpressure of feeding the filament out of the nozzle?
Thanks

Could be. A sent you an email, btw.

Ok, after your post of 20:12
Current M92 in config.g :
X640 Y640 Z3200 E400Changed to
M92 X80 Y80 Z1600 E822Commented two lines that set Z probe since I don't have mine yet.
Rmoved M92 line from script fileEdited last line in Config.g to change tool to T0 since I only have 1 extruder.
Moved T0 to M104 line in script file:Thanks

How many amps do your motors use? Should be a sticker on them.

Woah
I think it might be doing something, but it is really hard to tell. It took forever to make the effort to home all and it did that very slowly and so far it has not moved off of home.
I had forgotten the other change to M92. for the extruder settings so I have done that and reset.
I am still getting "attempting to extrude with no tool selected" and the extruder is not feeding.
-
After the last reset, the speed is ok, but still "attempting to extrude with no tool selected."
-
Under tools. M563 P0 instead of P1.
-
The G10's under it, change to P0 as well.

Make sure you do these steps too.

The sticker says Tevo 17HD4401-c5.18
Google was no help on that number. I found a posting on their facebook owner page where someone got a spec sheet. Theirs is 1.5A, and Tevo says 1.4 to 1.7 is ok to use.

Once you get everything squared away, you can up the numbers in M906 X855 Y855 Z855 to 1200 or so and even E up to a 1000 or so.
