Sensorless ENDSTOP problem

I’m trying to use sensorless endstop on T0 and T1. On T0 I get the option to use sensorless but on T1 the option doesn’t show up. This is because my endstop of T1 broke, and I need my machine to be running but ratrig is taking too long to ship my endstop. ...

Notifications integration in RatOS >= v2.1 - telegram-bot, Pushover, MQTT?

I've been looking for a way to have notifications sent from my printer. I've been using OctoPrint for my Ender 3 Pro for years, and have acclimated to the abilities. In that same sense, as I've been looking for more options for my VCore 3.1 300 that I just upgraded to RatOS 2.1 RC3, I noticed that KIAUH support has been removed (temporarily???). To that, telegram-bot, Octoprint, Pushover, or any g-code shell command interfaces, etc. are no longer available for a more daring hobbyist to utilize on thier printer.
My intent is to send a notification for when the printer is paused so I can change filament. I am currently building an ERCF (may actually switch over to a BoxTurtle), but all filament swaps are akin to sneakernet checking when an internet/text message would be more appreciated from any of my printers. What then, are the plans for KIAUH support to enable other Klipper add-ons? ...

IDEX input shaper values not being set correctly

I had a heck of a time getting decent print quality out of my IDEX 500. It turns out that the input shaper values I set don't get applied on the toolhead switch. It's looking for a variable in the RatOS macro. I had to add the following lines to my printer.cfg in the RatOS macro: variable_shaper_x_freq: [52.2, 48, 52.2, 52.2] variable_shaper_y_freq: [42.6, 38.2, 42.6, 42.6] ...

Configuration Bug Einsy

Hello, I tried to configure an old Einsy board for Klipper. I've done the bootloader stuff, and it worked out. Upon starting the Ratos Configuration, the first issue, though a minor one, was Ratos not being able to query the board successfully, but since the usb-connection is known to work, and you can skip this, I didnt give it much thought. During the printer configuration, I specced a basically standard mk3, except for a triangle labs bmg 3:1 extruder. For the part cooling and hotend fans I chose Input voltage pwm. When I wanted to complete the setup, it threw an error, that i can't circumvent. Changing the board settings to digital pwm for testing did nothing. It's worth mentioning, that I also got an error, when I tried to set X and Y Accelerometer to "none", however switching to host connected accelerometer solved that issue for now. I did WinSCP into the pi to see if the Pins are specced in the configfile, and there was a set pin for the fan. ...

Nozzle expansion offset gets reset by an order of magnitude at the start of a print. VC4/500

I've gone through all the Beacon calibration and it comes back with a sane number. (e.g. T0 expansion coefficient 0.069375) and then when starting a print the Z offset will be wildly off either + or - by millimeters. So the prime blob will start in mid air, or in this case, it drove the nozzle into the textured PEI and the extruder was clicking because it was trying to extrude inside the PEI surface. I haven't tried setting the expansion to false yet. ...

Solution:

Doing the double "SAVE_Z_OFFSET" in the console while the print was going actually seems to have worked.

RATOS SSID keeps appearing after some time

I had a bad wifi reception so I bought an external access point -> ALFA Network AWUS036ACHM. In order to force the connection exclusively with the new interface, I added 'denyinterfaces wlan0' and now ratos only uses the new wlan1 interface. All works great after a reboot but after sometime , usually 30min, I loose the connection with the printer and the defaut SSID 'ratos' appears. Can somebody help me understand what is happening?...

Solution:

Yeah don't do that. Use the configurator to set the WiFi

Changes to Start_Print and End_Print

Hi, I would like to know what and how to make changes to G-code or printer config in order to accomplish a few things: 1) In End Print: keep bed heater on x amount of minutes after the print is finished. I often will start a print after one ends and have to reset the bed temp to make sure it's not losing heat before the next print. 2) In Start Print: Do not turn the hot end down to 150C prior to print if it is already at a higher temp (i.e. from a filament change between prints)....

Prime blow messing nozzle

I have just upgraded to the latest RatOS. I have always used my own Start_Print macro but I wanted to use the default one now as it is much better. The issue I have is the prime blob. The nozzle is too deep into the blob & when the prime blob is finished the nozzle is covered in plastic. Is there a way to adjust the height of the nozzle for the prime blob without messing up the whole start_print macro?...

Move exceeds maximum extrusion (0.2mm nozzle)

I'm getting this error after swapping to 0.2mm nozzle: "Move exceeds maximum extrusion"... The nozzle diameter doesn't seem to be set in the printer.cfg - it's 0.2mm set in the printer config wizard. All the settings used to be in the printer.cfg - but since upgrading to RATOS v2.1 things seems to be done differently - unless I have set things up incorrectly? I have set the 0.2mm nozzle in the slicer. Never seen this message before....
