Beacon Z-Offset woes

Hi all. I am having issues setting my Z-Offset. I ran the BEACON_RATOS_CALIBRATE BED_TEMP=50 command for PLA. It ran all the way through and in the end I think it saved the config because it did restart. Went to perform my first print and had to step the head down -0.168. Stopped the print and tried printing a single layer 150x150 square. Started the print and sure enough, had to step down to -0.168 again. This time, before the first layer ended I ran a SAVE_Z_OFFSET followed by a SAVE_CONFIG. Started a new print and again, -0.168. ...

Layer shifts/clunking after 3.2H upgrade

Hey folks, I've had my RR 3.1 running great for years with a few minor upgrades; I was running stock + EBB42 toolhead board and dual (extrusion-less) linear rail. It's been rock solid. Recently a stepper motor died on me so I decided to upgrade to 3.2H since it came out recently. I switched from EVA to the RR toolhead with beacon and went back to using the original 2020 extrusion gantry (as the extrusion-less upgrade doesn't fit the new joiner printed parts)....

SAVE A SOUL and help me make sense of this!

Some history (from FB group): After a power outage, my printer began a job then stopped mid-print. I suspected the Raspberry Pi, so replaced it. Now I can’t get the software to flash the Octopus or toolheads. With everything disconnected, I can flash the Octopus via USB power from the Pi, but since the Pi can’t power the toolboards too, the install fails because it can’t detect them. When I power the Octopus from the PSU instead, the Pi no longer recognises it—so I can flash the Octopus on USB only, but not the toolheads; and with PSU power, not even the Octopus is seen....

Bed Thermistor is kinda moody

See picture - I've seen this before but never so clearly. The printer has not been moving for 14 days. You can clearly see dips in reported Bed temperature when compared to Chamber thermistor, that is on the rear frame profile. Any ideas what causes these dips?...

Ratrig V-Core 4 IDEX 500 error

I just started to get this error today. Not sure what should look for? Stepper driver warning: OTPW flag set The stepper driver 'stepper_z2' has triggered the OTPW flag and may stop working if it gets any hotter. This is an indication of an over temperature condition. This can be caused by a too high current. Please check the stepper driver settings and cooling....

Strange non straight parallel lines while printing

Vcore4 500: I can't figure it out - why are those lines not straight. I can't feel any binding on both Y and X movements. If I make a smaller print it doesn't show up. Also I am not sure I see the same defect on the opposite diagonal.

Solution:

And not sure why I didn't take into consideration your reply... It turns out it is over extrusion and lowering the extrusion factor this is issue is resolved... I should learn to read what it is actually written. Thank you for your reply.

Can't access my printer at http://ratos.local

Hi there good fellows. I am using windows 10 and happened that my browser can't access ratos.local Don't know why. First I connected my wifi to the ratOs Hotspot using password raspberry and everything fine... So I expected to connect via browser as well because it is the next step at the commissioning guide. No problem. Tried my mobile phone using android and exactly the same answear. Any guess how to solve this?...

BTT SKRat V1.0 V-minion X and Y endstops will not trigger.

i believe i am out of options on what to do for the title issue. i have arranged the wires for the X and Y endstops appropiately for the SKRat board and per the RATos documentation. signal and ground are hooked up for each, both have correct pin mapping, pullup's have been added to each endstop pin, and i have physically checked voltage and continuity for all connections, wires, switches, etc.... the only way i can see them "triggered" is if i add the ! in front of the applicable pin. below is m...

"No Beacon model loaded" after attempting to run "BEACON_INITIAL_CALIBRATION"

Hello all, I am attempting first time commissioning of an IDEX Ratrig Vcore4 500 printer. As mentioned in the title, I run into a snag when attempting to run "BEACON_INITIAL_CALBRATION". I get through homing all axes and print head T0 moves to the center of the plate and then "No Beacon model loaded" is output to the console 5 times. I've tried some light troubleshooting from the beacon documentation such as listing what models are available (there are none) and trying to generate my own default (unsuccessful). Does anyone know what I am missing here? I will continue to troubleshoot but I was hoping to find this is a somewhat common and easy issue to resolve. Thanks in advance!...

Solution:

I'g going to close this as I ended up finding a solution on my own. My problem ended up being that the beacon probe wasn't fond of one of the usb ports on my raspberry pi. I switched to an open port on the usb waveshare pi hat and that resolved my issues immediately.

Orbiter motor skipping steps

Hello. I have encountered a problem with Orbiter extruder motor. After a while, printing with enclosed RR, extruder starts to skip steps. It feels very hot, although I can not measure the temperature, but also I can not touch it for a few seconds because of the heat. Any ideas what to do?
