Hello, despite attending one of the top computer science schools in the country, my entire schools ethernet has been down all day so I only had access to wifi on my laptop running arch linux. I had to make a few minor changes to the firmware for my printer so i decided to try and build reprapfirmware on linux. After a few hours of messing around I finally got it to compile. Here is what I did, but please keep in mind that I did this for RADDS on 1.19, and that I did this on Arch Linux which is a little bit different than most distros…

Install Eclipse through pacman

[[language]]
sudo pacman -S eclipse-cpp

As described in BuildInstructions.md, download CoreNG and RRF, create a workspace (doesn't matter where), in my case i created one in /home/Documents/Firmware, and move folders there with proper names as described. Some of these packages are probably unnecessary but it doesn't hurt to install them all

[[language]]
sudo pacman -S arduino arduino-avr-core arduino-builder  arduino-ctags arduino-docs arm-none-eabi-gdb

You would think that the pacman arm-none-eabi-gcc and arm-none-eabi-newlib packages would work for this but they don't. You need to use a community made package in order for RRF to compile. Doesn't matter what folder you install it into.

[[language]]
cd /home/Applications
git clone https://aur.archlinux.org/gcc-arm-none-eabi-bin.git
cd gcc-arm-none-eabi-bin
make -sri

Then open eclipse, import both projects as described, and open the project properties for CoreNG. Under 'Settings', change 'Cross Settings' path to '/usr/bin/arm-none-eabi-gcc'. Then go to 'Tool Chain Editor' and change the 'Current Builder' to 'CDT Internal Builder'. Repeat for RRF. All thats left is to build CoreNG followed by RRF, and then that's it! Hope this helps others!

Hello so I am having an issue where when I set the heated bed to say 60C, the heated bed is getting power in very short blips. Both the led next to the mosfet on radds, and the led on the heated bed, blink at a consistent rate when I turn it on. It looks like it is only on for a very short blip, every half of a second or so. In my room the bed lies around 22-23C, but after having the bed blinking for 30 minutes it reaches 26C, so it is working. I believe the issue is the PID parameters. This is my config file, if someone could tell me what I am doing wrong that'd be great. The bed I am using is a standard pcb heater from an old anet a8. Here part of my config.g…

Hello, I am new to RFF and am trying to install RRF on my custom designed IDEX 3D Printer. All of the motors are using the RAPS128 driver except for the extruders, which are using drv8825 stepper drivers. The two motors using the drv8825 drivers make a high pitched noise and dont move when i send the command for them to move. I have the things on the bottom of RADDS properly set for 1/32nd stepping, and I have checked all of the connections. The motors work with raps but not with the drv8825 driver. All motor currents are properly set for the current rating of the motor. I believe the issue lies in the configuration but im not totally sure. Are the drv8825 drivers compatible with radds and RRF in the first place. I have attached my config.g for reference. Thanks!

Hello, I am a new RRF user trying to install and configure RRF for my custom independent dual x axis 3d printer. I am stuck on trying to figure out where to wire the U axis endstop and how to get RRF to recognize it. I have tried plugging the end stop into every single min and max endstop pin on radds minus the ones being used(x min and y min). Where do I wire the U max endstop to on RADDS and what do I have to do in the config to map the U axis endstop to wherever it is plugged in? I have attached my config.g for reference Thanks!

P3 is the only one that doesnt give me an invalid servo index for M280 and that doesnt work. The issue is radds actually uses heater 3. H3's pin is 21. I think to fix my issue I need to direct M558 to pin 39 instead of heater 3 in order for it to work.

So I have been trying to get my BLTouch sensor working with reprap firmware on radds but have been unsuccessful. I currently have the black and white pins connected to z min, and the other 3 pins connected to pin 39 or PWM3 on Radds. From my understanding reading other bltouch related threads, M558 P4 uses pin 39 while M558 P5 uses pin 5. In the z probe documentation for reprap firmware it says to use P5 for the BLTouch however most people use P4. I have tried both P5 and P4 however I cannot figure out which pin on Radds is pin 5. Whether I use P4 or P5 the Bltouch does not respond to any of my commands even the retract and deploy probe commands. Whenever I try to home Z, I get an error saying something like the probe is already at min. One thing I noticed is if i turn on the printer normally, M119 returns z min: at min stop, z probe: at min stop. However if i turn on the printer and hold the bltouch pin to put it in the error state, then M119 returns z min: not stopped z probe: at min stop. I also am not using the bltouch's 3.3v logic because its stealing 5v from an lcd pin and that seemed to have worked before with marlin. I know for the Duet the 3.3v logic needs to be turned on but should I turn it on in this case? I believe the problem with the bltouch lies in the config.g trying to communicate through a different pin but I'm not sure. Please let me know what you think.

Okay so I fixed the endstop logic but am still having troubles with the bltouch. I can get it to home the x and y but when it goes to home the z it says the z probe is already triggered. Here are the lines from my config.g for the bltouch. I've tried setting p as both 5 and 4 just but neither work.

I am also having an issue with thermal runaways. When heating my hotend, I configured it so it heats slowly but even when it hits its target temperature it continues to heat. The entire time it is heating up, it does so in bursts. I dont know how to configure the pid properly please help.

M301 H2 P0.1 I0.10 D100 T0.10 S1

Okay so I changed the M574 command to use S1 and now it is responding to the endstops however the logical is inverted. How do i invert the logic?

As for the bltouch I do have the deployprobe.g and retractprobe.g files, but when sending those commands myself through simplify3d, I cannot get the pin to move on the bltouch. I would try to home Z but when i do the x and y axis start grinding because the logic of the endstops are inverted.
