So I've setup a few duet boards in the past but this time Im falling at the first hurdle.

The SD card was formatted and files transferred to it. On first power up, terminal on Mac seems to be able to connect but as soon as you send M115 the serial connection is closed. Thinking this was a Mac issue I tried this on a PC with Putty. Same issue. And then even tried YAT but all serial programs either report a communication error or disconnect. Its as if the response fails.

The firmware.bin file appears to have been renamed on the SD card so assume the firmware was installed.

I just don't know where to go from here. Any ideas would be appreciated.

@droftarts Thats a good heads up. Thanks

@T3P3Tony Yeah exactly. So just find one with the right RPM for cutting the material?

Hi guys I'm building a tool changer which will be able to insert screws. But I am also interested in creating a countersinking toolhead and wonder what the best way to implement this is. Ideally need a small sized motor. Was thinking about a brushless motor but reading some of these threads on brushless motors they may not be the easiest thing or the ideal thing to implement with Duet hardware. Any suggestions on this would be really helpful and might help others.

@jay_s_uk Ok. Thanks for your help its much appreciated.

@jay_s_uk I read something in the read me file on GitHub about editing locally. Does that mean you can edit DWC by accessing the RPi directly? Would that be via nano or something? I don't want to make massive changes.

@jay_s_uk So if you connect a display via hdmi to the RPi then it'll show the DWC by default?

Thanks for the plugin link. Its something to consider. The main issue is terminology like extruder and filaments which you wouldn't find on a injection moulding machine control panel.

Ideally id like to edit the actual DWC code. Is that possible? Im alright with code im just not sure if you can compile it and use it after editing.

@Phaedrux Thanks for that. I'll have a look at DueUI.

Did you mean yes it can be done on one raspberry pi or id need two? Can an operating system and browser be installed on a raspberry pi which is serving the duet control board?

I think klippers mainsail approach to ui customisation is good. You can at least re position panes and toggle them on and off even if it is all 3d printing orientated.

Im building an automatic Injection moulder which id like to use duet hardware for. However the DWC UI is heavily orientated towards 3d printers and the panel due even more locked down. I think Duet hardware would appeal to a wider market if the UI was more easily customisable for machines outside of 3d printers.

Can the DWC GitHub files be loaded in to software like visual studio for example, edited and then used to replace the stock DWC? How did ooznest make a custom ui?

What I want to do is use a duet 3 and RPi to host DWC. As the panel due isn't ideal for a machine like this im looking for alternatives. What im not sure is if that same RPi can be connected to a large touchscreen say 10inch + and be used to control the machine via DWC.

I think what Id need to do is have a second RPi for the large display which has raspian OS and chromium and setup it to run in kiosk mode fullscreen. Then access the controller by wifi by calling its IP address in the browser. However im not sure if DWC is touch compatible or what you do for a keyboard. Short comings in my knowledge.

If anyone knows a way to better achieve a touchscreen interface for machine other than a 3d printer without moving away from duet hardware, id be very grateful to learn more.

@alankilian Thats interesting but its not a duet or RRF solution. I was hoping for some RRF magic

I'll cut the the question and then if your interested in what its for i'll provide further reading.

Can a stepper motor speed be controlled based on its load. ie if the load on the motor increases it will speed up and if the load reduces can the speed be reduced? It almost like PID control I guess.

Ive built a winding machine for 3D printed filament and implemented some code using duet and RRF to create perfect winding on to smaller spools. Although it works quite well one of the important considerations is how to maintain tension on the filament so that the winding isn't too loose or too tight. I've mostly got the speed between a puller motor and a geared spooler motor perfect and have simply lowered the spooler motors current so that it turns but if the tension becomes too much then the stepper skips steps momentarily but is there a better solution? and does RRF have any tricks that might be useful here?

I have seen a winding machine running Arduino code do this by measuring changes in motor current and then changing the speed to compensate.

@OwenD Thanks. I must have been getting errors from another section of code.

Id like to run a few calculations.

for example (1 + 2) * 3 = 9 is not he same as 1+2*3 = 7 because of the bracket notation. But how do you implement this in RRF? Round brackets don't work and curly brackets don't work either. Is the only way to separate the sum in to multiple parts?

@Falcounet Fab. Thank you. There are no examples of this in the docs that I could see so wasn't sure how to implement it, brackets etc

Can you round down a decimal value to a whole number? Is that what Floor does but how do you implement it?

No. Thats not it. Removed underscores and the SSID still won't add. Maybe a MAC quotes issue although they look straight.

@gloomyandy Yeah My SSID isn't in there despite several attempts to add it. Think maybe its not adding due to an underscore in the network name.

@Herve_Smith I assure you I followed the guide to the letter because its been a few years since I last did this. I fully appreciate it say in several places that it will say no network found but you could do with some feedback to know your M commands are doing something especially if your disabling the wifi module but it continues to report errors. Just the way it is I suppose. I think what's happened is the SSID isn't being added to the remembered list. Are under scores in the SSID an issue by any chance?

@Herve_Smith Yeah. So entering M552 S-1 and I get no immediate output and the module continues to output no network found. Isn't that supposed to stop the wifi module?

@Herve_Smith Its Mac
