Hi there, I;m currently working on making a 5axis arm work with marlin, i can use marlin to drive everything and home correctly, but i want to implement the inverse kinematics. So that i can just run gcode. I was thinking about deleting the section "void calculate_delta(float cartesian[3])" at line 4251 in marlin_main.cpp and rewriting that with my inverse kinematics code(which i have already fiby Napalm1432 - Firmware - Marlin
Quotedc42 If you do want to print and/or upload files over USB, make sure that the sender does not wait for an OK response after sending each line of gcode. Many USB host programs have this as an option. Last time I looked, Octoprint didn't, but someone did a patch for it. I think i have seen some kind of option that looks like that, i will check after the weekend!by Napalm1432 - Duet
YES YES that fixed it all just a note for myself if i ever run into the same problem, when uploading the firmware with Bossa, do erase all and boot to flash I've tested it on pc and on the octopi both are now able to connect, tested sending the M105 command and got the right response! It doesn't seem to initialize the sd card in octopi right now though, i'm looking for a fix now Running an M20by Napalm1432 - Duet
Com port no shows up as Bossa Program Port even though repetier host SEEMS to connect, when i try from pronterface, it fails to connect however. It seems repetier host says it's connected when trying to send the M105 command. Just to check i also followed the instructions using the arduino IDE The com port shows up, and i can select the right board, when going to serial monitor, made sure baudrby Napalm1432 - Duet
After resetting the firmware a new device does show up under serial bus controllers as an unknown device: (Yes the correct lights were lit) EDIT: I also checked the SAM-BA USB Notice, which says to update that device with the driver in the samba directory, but when trying that, it says it already has the newest drivers installed (which i kind of weird for an unknown device but okay) EDIT EDITby Napalm1432 - Duet
Okay, so the issue of the usb host controller is solved, however, still no com ports showing upby Napalm1432 - Duet
yup, but i i'm also not able to go to the step of selecting a com port in those instructionsby Napalm1432 - Duet
i might be stupid right now, but shouldn't COM ports be listed under the device manager? Here's a screenshot of what shows up in device manager: When i knew the usb cable was good, i first tested it on the raspberry in the hope that it worked, but no luck, problem persists EDIT: When attaching an arduino it does show up though: EDIT: When i plug in the duet in my pc, it does not show com porby Napalm1432 - Duet
alright, so part of the problem was indeed the usb cable, when first pluggin into my pc it did nothing, now with a new cable it at least recognizes a device. But, that only solves the cable issue so far, when trying to connect it to my pc, i have to install the drivers, however, the only unknown devices are these: And when trying to update the drivers for them, they always fail. So, my next issuby Napalm1432 - Duet
I checked and there was actually already a jumper on the board 5v enable, i tried your suggestion to do the command ls /dev with and without duet attached. Sadly, it doesn't seem to want to show up in the list... The question now ofcourse is, how can i fix that partby Napalm1432 - Duet
i attached a power supply to see if that might have been the issue, but i still get the same error. I also put in the same settings as Maso, however, i cannot select a serial port other than auto, so still no connection EDIT: I do notice, that the 5v light on the duet board doesn't light up untill usb is plugged in, even though the Vin on the duet is on, do i need to set a jumper next to the powby Napalm1432 - Duet
Hi there, So i was planning to use a raspberry pi to run the web interface of the duet with a crosscable, failing at that, i thought it was easier setting up octopi and running that over usb (i'm aware of the consequences of slower write speeds). So i set up a raspi with octopi, using the adfruit 3.5 inch touchscreen, everything set up, until, i connect it to the duet board. When trying to conneby Napalm1432 - Duet
I am already using a crossover cable (a switch inside the printer doesn't seem like a good idea) I had tried accessing the web interface, but it won't load, anything i'm forgetting or doing wrong?by Napalm1432 - Duet
Hi there, I would like to add a raspberry pi as the display controller, and using the webinterface on the Pi. I thought of doing this by using the ethernet ports, and using a crosscable. I'm not sure if this is the way to go, or if another way is better. So far i haven't got it to work, so i hope someone can help me! Kind regards, Raymondby Napalm1432 - Duet
with uploading files to it, i assume you mean uploading files from the board to the sd card? If that's the cause, this will work fine for me, as i'm not planning on using thatby Napalm1432 - Duet
Hi there, I would like to add an external sd slot, or usb slot for a usb drive (preferably the usb drive). I did see that the firmware should support an external sd slot, and i'm assuming accesing usb drives works the same (correct me if i'm wrong, if so, is it still possible?) So i really have 2 questions here, could i use an usb slot, with a usb drive inserted? And how would i connect this toby Napalm1432 - Duet
Hi there, I just got my Duet electronics + expansion, and I have some plans as to how I want bed leveling to work. However, I need to adjust the firmware to fit these needs, I've done some adjustments inside marlin firmware, but never in reprap firmware, so i'm not sure where to look. Anyhow, my plan is as follows: I want my bed to have 3 axes (3 z motors) 2 in the front, 1 in the back. But i waby Napalm1432 - Duet
is the serial method used the same as with usb printing? example: let's pretend pronterface is the panelDue, and the usb connection is the serial connection Or do you use a completely different method? As maybe it would then be easier for me to understand what's exactly happening in your codeby Napalm1432 - Ormerod
Would you be able to point me to a scripting reference used for the display driver? or if it's arduino code, to the library used (i assume u need a library)by Napalm1432 - Ormerod
As an example you could look at the craftbot user interface, which keeps the interface really simple and easy to use, no need for classic buttons thereby Napalm1432 - Ormerod
Hate to pull out old topics, but couldn't find a more recent one. Anyhow, I was wondering if it's possible to replace the buttons with graphics, i saw some .bmp images being used inside a button, but i would like to use the .bmp AS the button. Any ideas on going about this? EDIT: The way i was thinking of going about this was to render the .bmp at the position, and check if the touch input is wiby Napalm1432 - Ormerod
Thank you for clearing this up! I was also thinking of making a seperate controller, with a seperate arduino (sd reader and potmeter built in(maybe opening for usb stick of possible??)) so you can just hook it up with usb to control any printer.by Napalm1432 - Developers
Hi, I would like to ask your expertise/advise on this: I want to add a adafruit RA8875 driver with tft screen to my printer (for this instance the ultimaker electronics) this board uses spi for communication.

Hello all, Let me introduce myself first since this is my first post, my name is Raymond and i'm a designer/developer. I'm currently building a SCARA Arm 3d printer and got some parts working. I'm using the Marlin firmware by qharley, edited byJCERNY to drive the arm.

Sorry to bring this thread back up, but i tried Abumaia's method, and it works for the most part. The problem i'm having is that it pauses 2 times in a row, now i did make the adjustments he stated in the last post which should solve the m600 command to be sent multiple times. But it still pauses 2 times in a row, is there any other way around this? Thanks in advanceby Napalm1432 - General
