Help - Stepper Issues
Finally got around to building my V-Core 3 with Oldham Z system from BRS.
Crazy long build but I believe all square and I think I did IMO, a very good job on wiring.
Setup is BTT Octopus 1.1 407 version with 2209 steppers.
U2C Can board with EBB42 - this took time but all working great now....
IP Webcam via USB on rpi
Does anyone know how to access the IP webcam from a phone connected to the RPI via USB? After typing in ssh it shows
usb0 but the ip address shown in the application and in ssh does not work. After wifi works normally but of course on a different IP. I would prefer to do it via USB to be WiFi independent
Y-endstop Not Close Enough
Upgrading from a 3.0 to 3.1 V-Core 3 and my y-endstop isn't close enough when the rail bottoms out
4028 fan PWM control shutdown MCU
Hi! Yesterday i connected my 4028 fan to control it with PWM signal. I used this tutorial (https://os.ratrig.com/docs/guides/4028/) and because the fan was still working on 0% i had to connect GND from step-down converter to heater 1 - output on mainboard and add enable_pin to the fan section in printer config. The problem is that i keep getting errors in random moments while printing but i realised that it happens on layers when the part cooling fan has to be turned on so I suppose that it cau...
New RatRig v-core 3.1 high vibration at lower speeds.
Hello guys.
I have a problem with newly assembled Ratrig v-core 3.1.
After first calibration (flow, e-step) I tried printing regular benchy. It printed OK, but I noticed a lot of ringing on all the surfaces (ringing on corners, a lot of "noise" on straight lines). During printing that benchy tool-head was vibrating making loud noise on certain speeds (~50mm/s). Please look at pic of benchy's hull.
I am using Super Slicer with all default settings.
However when I increase speed (eg. +100%) all noise stops and printer produced very crisp and nice prints. I even increased speed up to +500% and it was printing very well (some ringing but that's normal at this speeds)....
There seems to be no relationship between default fan speed and the actual reported fan speed of t
There seems to be no relationship between "default fan speed" and the actual reported fan speed of the 4028 PWM (which is set correctly to 25hz in printer.cfg) is it the same for others with the 4028 fan? The only thing that seems to influence the print fan speed is the "max fan speed" for some unknown reason.

Belt problems
Hello I have a problem on my v-core 3.1 400mm my belt don’t go in the bearing but between the upper bearing and the frame I tried to go down the pulley but it doesn’t change. Can someone help me please? (I can print but It fells like it took to much torque to move on Y axis)
