Mirror/Copy mode and cancel print not working

Hello, I recently opened a topic, but due to the late night it got a bit messy. The main issue is, that neither mirror and copy mode are working, nor cancel print while trying to use copy/mirror mode. system: Orca Slicer 2.2.0 with the preset RatRig V-Core 4 500 Profile. ...

Solution:

Solution for the IDEX 500 Copy/mirror mode issue for RatOS 2.1.0 RC3: - include this file into printer.cfg - set variable_nozzle_priming to False --> the printer will print without a primeblob. --> set the variable to "Primeblob" and it will do the primeblob...

Pause print nozzle temp

Is there any way to set the nozzle temp when the print is paused? I had some ABS burn in and clog the nozzle while the print got paused after a tangle detection while I was away for a couple of hours. I guess a temp of 150c would be a bit safer than 260c I presume....

Cancel print with mirror mode not working

Hello, I have a small issue with the mirror mode. First of all, I really don’t get it to work. Secondly, if I want to cancel the print, it’s still printing with a z offset. And then it stops due to a low temp on the extruder. That doesn’t seem to be right to me. Can somebody help me? https://cdn.discordapp.com/attachments/1223286652949106748/1352779968643465296/76429102546__BCE8C203-BB7A-4D40-9A73-4B2AB9FD44C8.mov?ex=67df4205&is=67ddf085&hm=a00718e166de2ad1671f9398569221f933bc24bcc89aa2a30799e40679e99d52&...

Print pausing after tool change (waiting for temperature)

I am able to set a standby temperature in the ratos config of the vcore 4 idex, but is there no way to make the toolhead preheat the nozzle before it needs to be used? I always have to wait 15-30sec before the printer is ready to print again. If I use the "ooze prevention" function in orca slicer the toolhead is correctly preheated, but I still have to wait till the not used toolhead to reach the standby temperature. I imagine it would be a quite easy implementation in ratos to set variable preheat parameter. If anyone got a soluton for that I would be very thankful 🙂...

TEMPERATURE_WAIT not doing anything

Hello all, I have done a fresh install of Ratos and ran into an issue I hadn't seen before, is there any way of fixing this? for context im using Prusa slicer on a Voron 0 Pandoras Box (hence why its configured as a vcore 3), is there a way of skipping all the pre print stuff, since it seems to just get stuck at that point and not heat up or do anything.

Solution:

apologies, I had changed something in the prusa slicer pre print gcode and it messed with it, I went back to the ratos recs and it works fine, sorry for wasting time

Automatic unload of Filament after "FIRMWARE_RESTART"

Hey there! Since I use the Orbiter Filament Sensor, everytime the "FIRMWARE_RESTART" is used the Hotend heats up and the Filament gets unloaded. Because the FIRMWARE_RESTART is normal start procedure for me, due to a shelly that seperatly can be triggered to connect and disconnect 230V for heatbed and else, this is very inconvenient. I guess this is not a normal behaviour? How can this be changed? Filament Sensor Code of printer.cfg can be seen in screenshot. ...

Apple iPad keyboard request not working

Hello, There might be a bug regarding the apple ipad app for mainsail. It’s not requesting the keyboard by touching the boxes as shown. Maybe there is something wrong with the implementation. The normal mainsail for my Voron printer is working as expected....

Settings migration from 2.02 to 2.1

Hi, is it possible to transfer printer.cfg or at least parts of it from 2.02 to 2.1? Mine printer cfg is pretty long and fune tuned and I would be kinda sad to have to do it again. Same with sensorless homing. Thanks a lot

Solution:

not sure what you mean by that. I am saying, you need to go to 2.1, use the configurator and generate your setup. Then manually look at your old printer.cfg and move over anything you need to the newly generated config from 2.1

Best way to install Fluidd in RatOS?

A long time ago I used Fluidd on my Ratrig. The feature I liked to best was the realtime printer viewer. I had some bad experiences installing it with KIAUH as the really messed up RatOS and I had to delete everything and start over again. Are there any recommendations on how to install Fluidd without creating problems? Do I just follow the manual install procedures posted on their Github site? Suggestions or Caveats?

Temperature Preset dialog error

When I try to add a preset for the bed/extruder temps, I get strange behaviour: Sometimes it works as intended (mostly after a restart of the whole system), but most of the times when I click on "add new preset" and start entering the name, it displays the "preset already exists" message until the name differs from the rest of the presets. But when I then save it, it overwrites one of the existing presets. For example, let's say I have the following presets already saved: - Bed 80 - Bed 80 / Extruder 150...

LED Status Actions

Regarding the LED status control built into RatOS, can anyone point me to the portion of code where the status changes are triggered? I see the variables ( https://os.ratrig.com/docs/configuration/led/#status-colors ) which seem to be driven from the led_control.cfg ( https://github.com/Rat-OS/RatOS-configuration/blob/v2.1.x/macros/led_control.cfg ), but I'm not quite sure about those _LED* gcode macros... are they some type of default status changes that just happen in the background in Klipper? In case the big "why" question comes up - I'm running a VERY old version of RatOS (v2.0.0.8) and don't want to rebuild a new config from the ground up since I have so many customizations, and the printer is running very well as it is. I just added some LED strips and want to utilize them for some visual feedback, so I just want to understand how the event triggers occur and how I can tap into them....

Webcam Goes Offline, Crowsnest Restart Crashes RatOS

I have run into an issue. The USB webcam I use (Logitech C270) will spontaneously stop displaying images after a while. I am not sure when the threshold of time is, but usually after some time it just goes out. This is the first issue. To fix this, restarting RatOS always works. However, recently I have been experimenting with restarting Crowsnest. 2 out of 3 times i have restarted Crowsnest using the restart icon in the power menu, the whole RatOS goes down: the web UI stops working and I can not ping or ssh into the device. On the Pi, the green activity light stays unlit. The 1 time I restarted Crowsnest and it worked was during the print… not sure if that was luck or what. ...

IDEX head collision while warming up!

Hi there, I'd just finished my Vcore 4 400mm Idex and wanna print a dual color dice. After homing, when both heads "meet" in the bed center for heating up, the T0 moves a bit to the left and when T1 comes in, it bumps hard against T0 loosing some steps. The result is an offset in X of about 3mm!!! tried serveral times - always the same issue. 😦...

They're different for a reason

Sensorless homing not triggering

I seem to be missing something obvious. Am trying to set up sensorless homing on my VC3.1 to reduce the wiring complexity. It's configged for sensorless but behaves like it isn't; X and Y endstops are constantly triggered unless the physical endstops are plugged in, and the homing responds only to the physical endstops, and not at all to the virtual TMC2209 endstops. X and Y endstops are set to the virtual 2209 endstops in printer.cfg, and RatOS.cfg is set up with the wizard for sensorless. Can...

Option 'control' in section 'extruder' must be specified

Updated from RatOS 1.2.4 to 2.1.0, updates and setup all went smoothly, but somehow my Orbiter 1.5 doesnt work properly anymore. In the printer.cfg under the [extruder] category, I noticed that 'control' and the PID settings for the extruder aren't commented out anymore (no # in front of the lines anymore), this used to be the case in my old printer.cfg. If I put a # in front of those, I get the red error message as seen in the screenshot. if I dont put a # in front of those lines, my extruder wont extrude nor retract filament. it just shakes and sounds like its skipping all its steps. What am I missing here?...

Solution:

it was a faulty stepper motor cable
