@perseveranze You wouldn't need Mach4 with the Duet, you would create your gcode from your favourite cad/cam tool like Vectric Aspire, Fusion 360 etc and then upload this to the Duet via the web interface, the Duet then handles running the gcode and doing the motion control that Mach4 would normally do.

Very curious, I've been having similar perimeter quality issues with my Delta, it was built from day one with the bondtech and capricorn tubing. I always thought that I haven't got the retraction dialed in just right but perhaps its time to go back and try regular tube, its a cheap enough test.

thanks for sharing.

I built a DC42 Kossel, but one thing I could not source was the linear rail, I went taller (~1.8m) and although at the time I worked out my BOM when it came to ordering, RobotDigg cancelled my order and other sellers in Ali Express either said they had it and then didn't, or in one case agreed a discount for 3 lengths and then took the order and then wanted more money. They eventually refunded.

In the end I went with the think3d carriages and shaped wheels that run up the 2040 extrusions which so far i have been quite happy with, but ultimately I would like to get linear rails.

@dougal1957 1.21.2-dc42 was the that was on the Github with the firmware and its newer than on https://github.com/chrishamm/DuetWebControl so perhaps a pointer to the newer version would be helpful.

One very minor bug with the latest DWC, on smaller screens the text for speed is mangled, I think with some reduction in padding this should be fixable.

I'm using the 17HM19-2004S motors on my 1.7m tall Delta without issues, I wanted to use linear rails but was unable to source them. Ali express sellers said they had them but they let me down wanting more money and robotdig went out of stock after I ordered. I ended up with 3d printed carriages (the think3d ones) and v tracked delrin wheels. These worked well with the smart effector kit.

This was the carriage - https://github.com/T3P3/kossel/blob/master/Release3/STLs/R3-Vroller-adapter-V02.stl

If anyone's interested I have created a wrapper for the DWC interface available here https://github.com/DACreates/DWC-Desktop-App/

It basically does what the web browser does but without the browser chrome and keeps the process separate, you can have multiple copies each linked to a separate printer too.

@sparkymark79 I have the same ones (PA-20) and they work great, I initially got the generic JST style crimper and failed miserably and making good crimps.

@newyork347 said in Having issue printing walls with Duet 3D:

lso printed cube with Trigorilla and Duet WIFI - they look same. What could be a problem ? I opened different topic, but I'm thinking problem

There's a bug in the current version of Slic3r that causes this pattern, they say its to do with printing the inner and outer walls at different speeds with different cooling, maybe the same could apply to your Cura settings.

@dc42 This is already possible, I have the following in my end gcode -

Yes. It’s been running like that for 6 months without issue. My biggest problem was the extruder. I bought a Titan extruder but it didn’t have the grip for my tube. I’m now on the Bondtech and never had a problem.

Here’s two pics of it finished showing the cables etc.

@mysta Yes, My towers are just over 1.7 meters tall so i just made up some cables before inserting the towers into the base.

For anyone interested there are a few build photos of my printer here - https://imgur.com/gallery/O1jtC I do need to add some of the finished printer but these give an idea of size and include the custom table I built which suspends the filament under the table on a lazy suzanne.

All my end stop cabling runs up each tower on the inside (the center of the extrusion) so its totally invisible, even at the top I cut a small section out of the back of the slot to allow the cable to turn and come back down to the stop switch, cabling to the effector and extruder run up the rear tower in the slot on the back. I'm using a slightly modified version of DC42's cable clip.

The cable then passes over the top of the extruder and is spiral wrapped to the bowden tube down to the effector.

@mysta they didn't have anything in the 1.5m lengths even though they were advertised, hopefully that's changed now, please let us know if you go for it.

@mysta Will be interesting to see if they have them in stock, every time Ive ordered from them they've not had them, and other sellers on Ali took the order and then asked for more money, which I refused.

@Biggsis:

Thanks for you nice words, I don't think, that I ever insulted people, but of course I will ALWAYS discourage people from using any kind of mains in their printer. I (and most of the others) am a friend of SAFETY and precaution. And in most countries you are legally not allowed to mess with mains anyway, so that should be avoided in your printer too. My 2 cents. You don't like this safety measures, well, there is no obligation to join the group

Still everyone is free to join the group, even if (as a trained electronics engineer) I will always recommend low voltage (12V /24V) heatbed solutions….

The 240v AC silicon heater I added to my Kossel is one of the best heat beds I've ever had and would recommend it.

@fma:

My upload speed is more like 200-300kB/s… But I don't send big files.

I'm wondering if the Duet ethernet can upload at a faster speed?

I get the same as you with the Duet Ethernet and the SD card supplied with it. I never reformatted the card just used it as is.

@dc42:

The basic port to use RTOS is now working. Currently RepRapFirmware is running with just two tasks (one for heating control and one for everything else). The next step is to separate out the networking subsystem into a separate task, followed by GCode processing and movement. I've not yet decided whether to use a task for generating the step pulses or to leave that as an ISR.

The RTOS I chose is FreeRTOS. It is small and lightweight, ideally suited to embedded applications on ARM Cortex processors. It's coded to high standards - it claims compliance with the MISRA-C coding standard, which is the one used widely for critical C software in automotive, aerospace and other sectors.

Does this mean we might see the ability to upload a file at the same time as printing?
