Slicing software can take obj and 3ds files as well. Are these also incompatible with arcs ? I have read somewhere that there was an option to preserve smooth arcs inside slicing software. Not sure if it's still up to date... Also found this quite interestingby unromeo21 - Duet
Quotedc42 I think you are the first person to ask for support for G2 and G3 on RRF. Slicing programs for 3D printers don't generate them. What application are you using that does? I'll add G2 and G3 support to the firmware wish list. Controlled Arc Moves (G2 and G3) are generated by other tools not intended for 3d printing (like my example with Inkscape and J Tech laser cutter plugin). But I bby unromeo21 - Duet
Just curious ... I noticed that most of the other firmware have already implemented G2 and G3, but not RRF. Are there plans to introduce this in the future ? This is kind of a let down so to say... I was trying to plot something (first with a pen, later will use a Laser) and noticed that my drawings are not what they should look like. There are a lot of G2 and G3 commands in the G file that theby unromeo21 - Duet
Oh, I just hijacked this thread to ask a question, so I won't have to open a new one. I am building my own heater and was thinking of ways to control it with the duet...by unromeo21 - Controllers
Quoteo_lampe Why not use a linear actuator to move the plotter pen up/down? This would be much easier to implement. Maybe electronically. Mecanically it's way easier with a servo. And the servo are already lying in the drawer. Maybe would be easyer to interface an ATTiny between the servo and the Duet ...by unromeo21 - Controllers
A question for the electrical engineers out there : is it safe to drive a power mosfet like IRFP4004 from the heated bed output on the Duet ? Basically using the integrated mosfet on the duet to drive the external more powerful mosfet. Everything is going to be powered from only one 12V power supply. Unfortunately, I am not that knowledgeable when it comes to MOSFETs... don't know what is bettby unromeo21 - Controllers
Any updates on this ? Anybody managed to control a servo with the Duet ? I would also like to do some plotting with my printer, and a servo controlled pen would be much faster than moving the 8Kg Z axis up and down all the time.by unromeo21 - Controllers
Old post, but here is my take on it: For 12V power supply you could go with self adhesive copper foil. Way easier to lay down and stay flat. plus you get a better thermal contact. You can use this calculator to compute the length / width of the trace. The most common copper foil is usually 1.4 mil thick. For electrical isolation with the aluminium bed use standard kapton tape. Same tape to be uby unromeo21 - Experimental and Hobby
Quotedc42 Btw there is a web based configuration tool in beta that will generate the configuration gcodes for you. Oh, that would be a really nice feature for those that just jumped into G-code boat. A web based tool to generate config files, much like the repetier configuration tool. DuetWiFi is one of the most advanced controllers on the market at the moment.

That's why I am designing my printer to keep the frame cool but the inside of the printing chamber warm. I'm going to try the Stratasys method with the bellows right under the X axis and the walls will be within the frame. So practically, all the supporting structures will be outside the heated chamber.by unromeo21 - CoreXY Machines
or you can bolt the X rail directly onto the aluminium bracket and leave the extra bearing block.by unromeo21 - CoreXY Machines
Thanks DC42 ! This is what happens when the information is scattered all over the place. I was reading the reprap.org wiki, configuring duet for Cartesian; same content almost, but this specific detail is missing there. Regardsby unromeo21 - Duet
So I am commissioning my Duet on my home build printer (cartesian style, bed on Z axis) and decided to skip a Z probe at first, just a simple optical endstop on the Z axis, same as X and Y. Now, this low end endstop is positioned to trigger a few mm before reaching 0 (when the nozzle should touch the bed). I was going to setup an offset for the endstop, and issue a G1 Z0 in the homez.g file toby unromeo21 - Duet
Quotedc42 Would it be possible to use your code for the ESP8266 and the modified DuetWebControl which you implemented in the DuetWifi to add WiFi capability to a Duet 0.8.5 ? (although a wifi to LAN bridge would be a far less difficult to implement). If this is doable, how would we connect the ESP to the Duet board ?by unromeo21 - Developers
I am going to change my plan, decided to make a 220V heater after all. Switching a 12V at 55Amps is not an easy task. I do have to proper MOSFETs but for such powers, it's better to go with AC and SSR. Just have to be very careful regarding the insulation. I found flat Nichrome wires of 0.8mm wide and 0.08mm thick. They are used for electronic cigars (ebay). 17 Ohm per meter. This would be perfecby unromeo21 - Reprappers
Quotedc42 Aim for a power density of about 0.4W or 0.45W per square cm. The usual choice of heater for aluminium tooling plate is a silicone heater. These can be ordered in custom size and power ratings from China at relatively little cost. Yeah, I am aware of those silicone heaters, I'm just aiming at sourcing locally or doing it myself, you know, learning by doing. I'm just not that good withby unromeo21 - Reprappers
Hi everybody, So as the title says, I want to try my hand at building a heated bed out of a tooling plate 6 mm thick and a custom made heater, from self adhesive copper tape (3-4 mm wide) between two sheets of kapton foil. Basically, something looking like these commercial versions : The heatbed will be around 350 x 350 mm in size. I was planning on using a high power 12 volts supply, up tby unromeo21 - Reprappers
Can you tell us more about the performance of the drivers ? How do they compare with the "old" ones regarding noise, smoothness ? To me this would be the greatest plus over the current controllers on the market.by unromeo21 - Duet
Why not use the 5VSB from the ATX power supply to power the microcontroller, and the PS-ON to turn on the PSU to power the heaters and fans and steppers ? No other external relay or SSR required. Yes, the microcontroller will be always on while the ATX power supply is plugged in the mains, but it would be an advantage to have it turn off all the other power hungry devices once the printing is doby unromeo21 - Duet
