2.1 Installation stuck at ratos-configurator

After failing to get 2.0.2 running I was advised to try 2.1 but ran into some problems. I followed the Installation instructions with the latest RC2 image. Connected via Ethernet I did the ratos update and I am getting stuck on the ratos-configurator showing "###### Updating npm and pnpm..." for an hour now.

EBB42 flashing/setup via usb(data only) + 24v

Full rebuild of my v-minion, I only have data and 24v going to the tool head through my umbilical. Before i fire up ratos setup, is this wiring fine or should i use a usb cable to flash and then go back to my umbilical?

Solution:

And i just sent it at like 2am last night and that worked perfectly, all 3 boards flashed perfectly

Default Filter Fans Speeds don't meet Ratrig Docs

I recently bought and set up a Ratrig Chamber Filter. I got it working but there are a few discrepancies. The on-line docs state the that default fan speed is 1.0, or 100%; however it runs at 50%. I found this setting in a configuration file chamber_filter.cfg where it has this: variable_chamber_filter_speed: 0.5
One or the other needs to be changed to make them the same....

Pressure advance doesn't seem to get implemented

since i changed to a 0.5mm nozzle, i did some PA tests with Ellis' tool. However, the results afterwards seemed off to me. I printed this part 3 times, with PA values 0.045, 0.055 and 0.095 (to test), but the results are mostly identical. IN the PA testprint from Ellis the results do vary a lot, so i seems that the values in my cfg dont get implemented in the actual prints.. thoughts?...

"Must home Axis first" When trying to home after fresh 2.0.2 Install

Just updated to a fresh install of 2.0.2, made all the updates and did not have any errors in Mainsail anymore. I verified all end stops work and axis move correctly with "SET_CENTER_KINEMATIC_POSITION", the BL-Touch failed homing (my fault: triggered at a different height by me) and I tried rehoming all axis. But whenever I try to rehome all Axis I get the error "Must home axis first: 0.000 0.000 15.000 [0.000]". Happens also after a restart. I also added my old printer.cfg which I migrated some settings from....

Can report, its alive and working, now to the fun part.... tuning

Rat rig VAOC 3DO Webcam not working in visual calibration

My hardware: Vcore 4 idex kit, all the default parts. Camera is a VAOC 3DO Problem: the webcam works on my latop, and also works on mainsail but only through the settings screen using ustreamer. camera-streamer doesnt work in the settings, neither in visual calibration despite crowsnet conf being exactly as specified in the commissioning. The crowsnest log DOES show the webcam, its device name, that it gets loaded to /dev/video0 Attempted Fixes:...

DC slammed on Homing after Set Kinetic Centre

If you set kinetic center and then try to Home, the T0 will home fine however DC will get slammed at the end stop. The only way to avoid this is to restart firmware. VCore4 300mm nothing crazy in the config....

Solution:

that is what set kinematic center does. It says to the printer - ignore everything you are at 250,250,250 (assuming a 500mm printer). So then when you home, it tries to move 250mm in all directions as you told it to

MCU 'Toolboard t0' shutdown: Timer too close.

This error happened often on my v-core 4 500 IDEX, at first i thought it was my ssd, then the underpowered pi, so i switched the ssd and have given it a direct power supply. it's been more than a month, i don't know what to do anymore, please help me......

Solution:

i switched the usb to a new one and the problem didn't come back, probably the usb had gotten damaged somehow... I had one of the rat-rig provided ones with the nylon coating.

Wrong skew profile tries to load

I previously had a skew_profile made up (in printer.cfg) with the name "tuurke_skew". This worked fine and did not give me any errors. I recently rebuild the printer. I removed the skew profile as well as the reference in the variables from printer.cfg. I re-calibrated the skew, stored it in the printer.cfg as "borg01" (as per klipper refference) and made reference to that profile in the RATOS variable to load it. Now, with every new print, at the start of the print, my klipperscreen warns me that it can not find "tuurke_skew" profile. (I can not find that warning at the Mainsail interface, but it shows up in klipperscreen)....

Solution:

what's this cos_custom_macros.cfg? it is what is saying to load the wrong skew profile

issues with vcore 4 500 PEI flex plate

I have a I have other PEI plates for my other printers so I know not to remove petg when it’s hot. The ratrig PEI sheet that came on my 500 is just eroding away even on the first blob. It is way more than i have seen in the past with PEI sheets. Did they get a bad batch at one point or are all Ratrig PEI sheets going to have this bad of an issue?

toolhead variable_standby on print start T1 toolchange does not wait for T0

Just found out that when I use variable_standby for both T0 and T1 and variable_toolchange_standby_temp and start the print with T1, then ratos does not wait on toolchange for the heatup of T0 but throws the min_extrude_temp error (bot at the same second):
