Z-tilt configuration

When working on running the Pressure Advance config print. The x and y and z homes ok but when it starts the z-tilt calibration, it errors when it goes to the back left corner for being unable to see the probe. The reason why is, it has dropped the back motor down so the probe can't see the bed. I've reset the bed position a couple of times with the same result. What do I adjust to get it to not drop the back z motor down?

VORON 2.4 SPEED DURING BEACON

Well getting pretty close to being able to run and tried my first actual non calibration print and hit an error. How do I reduce/control the travel speeds during the beacon scan and probing at the start of a print? I have been able to reduce all the other max speeds for my early version of Voron to handle but am unable to figure out how to slow down the Beacon stuff.

How to activate a PWM Fan with two PWM Ports

Can somebody help me to turn on a 12V PWM Fan via PD14 and PD15? I want to turn the chamber heater fan with 80% PD14 needs to be 1.0 (on) and PD15 needs to be 0.8 (80%) Is this possible without a "always on port" ?...

Vcore 4 400 IDEX - Z-Offset

I tried to finish the commissioning guide, last step: z-offset. I get the following error message: Error during homing move: Move out of range: 200.555 428.538 -7.000 [0.000]...

Solution:

With a little help from a friend and chatgpt we found the solution: We changed "position_min" for z from -5 to -8 so that -7 is not a problem anymore...

Having problem with the skew profiles

Hey, I just read Lemcott's thread after buying the CaliFlower Mk2 and having the same problem. Basically, I included everything in the printer.cfg, but the GET_CURRENT_SKEW doesn't change

Z Macro travel speed

I have TR8x2 lead screws and the current macros spin the steppers faster then I'd like. Are there variables for controlling the Z speed on all the macros similar to the XY, where the bed flys down and back up?

RatOS-v2.1.0-RC2 No boot

I have trouble upgrading from RatOS 1.0 to newest version. I downloaded the RatOS img file and verified the sha256. First installed the image on a new brand 64GB sdcard using dd: it creates two partitions and it looks fine, but it cannot boot my rpi3b. (permanent red led, no green blinking) Then i used BalenaEtcher with the same image and got the same result - I even tried three different sdcards. (including a new Sandisk as recommended) I tried to see if they would boot an rpi5 i had laying around..No cheese......

Firmware restart button doesn't work until I reboot the RPi

I have just installed ratos 2.1 rc2, fresh SD card with a stock image from ratos github burnt onto it. (Previously running ratos 2.0 on my vcore 3.) Now, when I click emergency stop, the "Firmware Restart" button doesn't work until I reboot the raspberry Pi. Possibly related: during config and flashing the mcu I couldn't get it to stop giving a warning about the mcu klipper version being different to the RPi klipper version. ...

The configuration manager has me stuck on "Waiting for DFU...". No options to flash, just waiting.

I've removed all jumpers besides boot and 5v, reset and still no change.

Configure new Hybrid 3.1

I powered up the v3 for the first time and made it to the homing checks. It homed to the back but went the wrong way to home the X axis. I have it configured as hybrid but everything I've read says to get it working without the hybrid belts first. Do I need to change the configuration to coreXY first then change it to Hybrid after I make it to that point? I was thinking that would undo any changes I have to make to get it working.

Solution:

It was a rookie mistake. I am using a different leadscrew guide then you and thought that it mounted to the top side of the extrusion instead of the bottom. I cut the leadscrew down and moved the bracket to the bottom and it is homing normal now.

Any way to functionally rename the [T0] macro?

I realize this might sound like a very odd question, but I'm caught in a sort of catch 22 here. I recently installed a Box Turtle AFC on my VC3.1 (single extruder) and have got most everything working great on it. The problem I'm running into now, however, is that Box Turtle's T0, T1, T2, and T3 lane load macros collide with RatOS' T0 macro. Everything Box Turtle wise works if I were to, say, comment out the T0 macro in RatOS.cfg, but then that obviously breaks starting a print. And remapping T0-T3 into T1-T4 works as far as Klipper goes, but OrcaSlicer gets really fiddly doing that (some discussion on that over here https://discord.com/channels/1229586267671629945/1368588039840071710). Even you put T{next_extruder + 1} into the slicer it still ends up breaking the AFC mainsail UI too as T[whatever-your-last-lane-is] will end up showing up as not used...so if there was any way to just alias RatOS' T0 over to something else that would be amazing. Can anyone offer any assistance or advice here please?...

Incorrect print history time after first print

I have noticed the print history is only showing accurate print times for the first part printed after a restart. Subsequent prints of the exact same file show wildly inaccurate print estimates and records them to the history. This may be a separate issue, but I also noticed the history is stating the print date is Jan when I have recently updated the time on the RPi to the current local time and date....

Prime blob volume

Running ratos 2.1 rc3.. I switched from a 0.4 nozzle to a 1.2mm nozzle and found the prime blob was gigantic. How can one control the volume of the blob - seems it should be independent of nozzle size shouldn't it?...
