Printing issues ...

@pdbeal setting a home offset like this and then making sure your travel limits are correct will not limit your travel across the bed unless that's a limitation in marlin 1.0.x in all 1.1.0 RC versions it works just fine
My offsets are x-7 y-39 and my travel limits are x0-280 y0-200 z-3 - 170 on my enlarged machine.

Your steps are probably off in the configuration.h file. The kit I received included (4) DRV8825 boards instead of the (4) A4988 boards. This means your microstepping is 1/32 and not 1/16, so your X and Y should be 160 and not 80 with the GT2 belt and pulley setup.
One thing to note that I noticed with my kit build, if you offset your home to something besides 0,0, your print area won't be 200

I have an industrial Siemens SITOP 24VDC powersupply rated at 10A with voltage adjustment from a demo kit that was scrapped, but had one of those hmm moments and figured to double check and ask if the 10A 24V powersupply would be enough.

So, I'm working on my third printer build and after going for the larger 300x300 print area I noticed all the heatbeds that size are 24V, since the Duet can function with 24V I figure I'll just build it around 24V. But, how large a powersupply would I need for a Duet with 5 motors (XYZ and Dual extruder) and a heatbed? On my 12V version, its a 30A powersupply. This is for the 0.8.5 Duet board

Does your slic3r configuration have the correct nozzle setting that matches your nozzle in the machine? Slic3r could be assuming you have a larger nozzle, so it's paths are further apart knowing the plastic would spread?

The stepper motor current is the pot on the top of the driver modules that are plugged into your RAMPS board assuming your using the Mega/RAMPS setup since you said Marlin.

Does it have the same issue if you change the bed control to bang-bang mode with M301 H0 P-1?
Have you tried the 1.12a firmware or the 1.13a firmware files with the same result since you said you were using the 1.13beta1 firmware?

I had a similar problem when I was first getting the Smartrapcore ALU version working, the bolt that was on the Z axis that was used to tension the belt made itself a hole through the belt. It would work for homing, but as soon as it got any amount of weight on the bed plate, the screw would pop through the belt causing a slack belt and dropping the bed slightly. I ended up just using a ziptie

I was getting a lot of vibrations and grinding and chunking on mine with the Ramps Controller. Replaced that with the Duet 0.8.5, and couldn't be happier. Runs smoother, and achieves higher speeds than the Ramps setup with only the controller change, and having the web interface to upload gcode to print makes it so much more reliable and less reliant on the computer. I did also replace the Z-P

I'll reslice it with Cura and see what it looks like, but I've run into issues with Cura not wanting to slice some objects. As it refuses to slice the attached stl file so I quit trying to use it.

I never changed the extra length on restart, so it's set to 0. I think I might have a small amount of over extrusion as the top surface of a box shows some ridges compared to the verticle shells on the outside of the top, but I wasn't sure if that would still cause the seam.

Seams - 7 years ago
I know there is the option in slic3r for randomizing the start/stop position, but is there any other way around hiding the start and stop seam? some parts get it really bad, others it doesn't seem to be noticeable. Any suggestions?

Ah, that'll work for me then for that issue.
On a different topic but still related to DWC, is there any way to make the time portion of the graph display a longer time? I'd like to be able to use the temp graphs to tune the PIDs, but for the bed I think it would need to show a longer time period. I am assuming the data for the graph is stored within the webserver and not the Duet firmware its

Out of curiosity, once you have finalized the latest design, what's the time-delay involved before Filastruder will have these boards or will it be month(s) long delays before the US supplier can sell / offer them?

Yea, all my browsers clear history on exit and the ones that can run in private sessions rather than storing any sort of information. If that's what makes it remember those values, I might have to just monkey around the html file and hardcode my options in there. I had hoped this might be some permission setting that didn't let it right some file on the SD card for storing the settings.

It is version 1.11, and I pulled it from github.com on 6/4/2016 and paired with firmware 1.12a-dc42 that was also pulled on 6/4/2016 from github.com
It also appears to be cookie related, as if I close Firefox and reopen it, it looses the same information too although I expected it would have saved this information somewhere else besides a browser cookie. Or if I open it on one PC and then open

Is there some trick to making the Duet Web Control remember the checkboxs and webcam url on the settings section through a power cycle? Everytime I unplug the 12V powersupply and plug t back in, the Duet Web Control has lost what checkboxes selected and the webcam url disappears.

I've seen a lot of people complaining they can't get past 90C with the aluminum heatbeds without insulating the bottom of the bed with cork or some other heat insulator. But that is just what I've seen as I don't have an aluminum heatbed.

That worked, although after I created a done.g file and uploaded it to the /sys folder,
M98 Pdone
didn't work so I tried
M98 Pdone.g
which did work.
I know it's probably asking a lot, but is there any chance of using macros like this and pass it other parameters? I was thinking about making a prestart.g macro that would normally be handled in slic3r, but would need to pass the temperatu

The only sensible way to cool those modules is to use a fan to blow air over the PCB, and not to stick heatsinks on the top (because they obstruct the air flow to the PCB ).
So would you recommend a fan on top blowing down, a fan on the bottom blowing up, or a fan on the side blowing across (on this one I'm presuming the fan would be near the SD card and blow towards the power connecto

So the 7" LCD from Filastruder that I ordered with the PanelDue board appears to have an SD socket on the back of it. Is this functional? Can this be used to insert SD cards and print from it? I know the Duet doesn't like to have its SD card removed and uploading through the web interface can be done, but just wondered if the SD card on the back of the 7" display was usable or not and if so wh

Is there any sort of .g file similar to the homex.g, homey.g that could be added for after a print is done, or does one already exist that I just didn't see? I'm currently using the after the job finishes code section in slic3r to do it, but that makes everything I print 160mm tall as the last entry before turning off the motors is to lower my Z axis to the bottom.

One thing to note, I upgraded the Arduino Mega / Ramps / 4x20 LCD boards to a Duet with PanelDue 7". With the base motors, the Duet is able to achieve higher travel speeds with ease, no grinding, no missed steps, no chunking. I'm not sure I'd go faster while extruding, but it is interesting even travel moves are speed limited by the 8-bot processing of the Arduino Mega.

Just to close the loop on this one, I have upgraded the Arduino Mega / Ramps / 4x20 LCD boards to the Duet 0.8.5 / PanelDue 7". With that being the only change, the system was able to achieve much higher speeds on all axis through the First test.gcode.
And on a positive side, the PanelDue for the Duet is miles beyond the 4x20 LCD screen for the Arduino Mega. I can't say I'd buy another Duet ye

At this point, if I can achieve higher travel speeds that would be sufficient, I know it can't print that fast, but it just seems so slow to move around sometimes and would be nice to remove some of the dead time.
I'm really not too interested in the whole direct drive, especially if I'm looking ahead to a future build I'm planning to try the kraken extruder head which 4 direct drives would be a

I've wondered about Simplify3d, but not ready to jump in the $149 game for something I can't try out first especially while I'm still dialing in my machine setup. You think it is worth it?
It talks about dual extrusion support, but any chance it also supports the kraken? My ultimate goal would be to build a printer that can print 450 x 450 x 700 and use the kraken with 3 colors and 1 dissolubl

You can see what z offset slic3r is using in the slic3r configuration.
Alternatively, it could be in the repetier firmware depending what you have for Z_PROBE_Z_OFFSET, as I noticed this appears to make the Z axis move down for a given length after the Z endstop is triggered.

Since lower speeds seem like a workaround, I've pulled the trigger and ordered a 0.8.5 Duet and the Panel Due 7" LCD from Filastruder. It'll be interesting to see the difference and to find out if higher speeds are possible.
In my head, I can't see a bowden corexy not going faster than 200mm/s, but it'll be an interesting trial for the 2 very different controllers.

I too am using a 0.4 nozzle. Just out of curiosity, if you go into your slicer config and on the print settings tab under advanced, set all your extrusion widths to 0.4 and see if its any different when it prints. Nice part with the 20x20 empty box, its very little plastic and very quick to print.
