limit speed

How do I reduce the max speed & accel. I have added the following to my printer.cfg file. The overall limits appear to have set OK but my bed mesh & Z-tilt are still trying to move too fast. The problem is I have changed the motors to LDO 2804s thinking that they had more speed but they simply do not have the power / torque for the VC-500. So I have to limit the speeds to be able to use it at all untill I get replacement motors. [printer] max_velocity: 300 max_accel: 3000...

How do I create a new printer configuration?

Hello. I want to create my own configuration in RatOS for my printer, which is not supported by the system as standard. Is there an instruction or short instructions for this? At the moment, the main problem is a misunderstanding of the overall picture of the dependence of some files on others (many parameters are specified several times in different files). When trying to create a completely new printer and specifying "template": "vostok-printer.template.cfg" in printer-definition.The error "Ca...

sensorless homing safe homing

Hello everyone, im having an odd issue, couldnt see anyone else thats had it and cant for the life of me figure out how i fxed it before. My V0 is doing sensorless homing and homing fine but when the toolhead goes to automatically return to centre it just buzzes like it doesn't have enough power to move, is there a different set of current settings that need to be changed for the post sensorless element of the homing process?

RatOS 2.1 vc3.1 and connected to internet

HI all. How to install RatOs 2.1 (I'm in the 2.02-36 ) on a vcore 3.1 to be able to use beacon contact? And do you know if it is possible to connect to the printer with the Internet to access mainsail from anywhere?

RatOS initial setup and configuration

I followed the steps for initial configuration and after that, I am getting an error. Since there isn’t much information about the troubleshooting, I hope to find the solution here. Where do I start?

X axis inverted after upgrading from 1.2 to last release :

Every thing went fine but when testing motion, x axis is inverted. I have tried all config of ! before dirpin in printer.cfg. Is it possible the motor wiring had changed in 2.0? And have only the problem on x motor?
Solution:
so looking carefully the picture, i think i was wrong : x homing = 0 , et y homing is ymax; so the right config is putting ! before each x and y pin; will try this

Cant get RatOS working on a Voron2.4 with Euclid Probe to Set Z height

I recently bought a used Voron 2.4 that had a Spider 3.0 board. My main printer is a Vcore3.1 running RatOS and I love the configuration and Software updates that go with it.
Since the Spider 3.0 is not supported by RatOS, I decided to purchase an Octopus Pro 446 to put in the Voron and set it up with RatOS.
I have most everything working; motors, fans, heaters, temp probes, end stops, etc; but I am stuck and having problems with setting the Z height and getting the Euclid probe to work. Whenever I try to home the Z axis, it first tries to do something the Euclid probe and then errors out when it doesn't see the probe. This might be the right procedure with a VCore but on...

Adding parameters to END_PRINT

Hi folks, just don´t want to change the END_PRINT macro or pull it out and add it to an own cfg. I really would like to move z to a defined hight like 200 before the motors are switched off. ...

RatOS 2.1 Manta M5P Missing motor configuration in RatOS Configurator

I am trying to install RatOS 2.1 on a Manta M5P board and at the very last step in the configurator I get errors because stepper configuration is missing. In the previous step I can choose the motors and then in the last step I cannot Confirm and Save since config for the Z1 and Z2 motors are missing. Error...

Adding more Z steppers to config

Hello, Im in the middle of doing a voron 0 pandoras box build, im using the voron 0 example config, The issue is that pandoras box has 3 point z tramming, How would i go about adding parts into my config to make these new 2 steppers work? im using the skr pro 1.2 so have enough stepper extruder drivers. Im thinking would it be easier to config it as a vcore 3 and just change the size and add sensorless homing?

RPI Cam and Screen

BEACON_INITIAL_CALIBRATION moves the head to incorrect place, crashing head

Vc4 400. v2.1.0-RC2-106-g8614d79e. Most of the time the BEACON_INITIAL_CALIBRATION works ok. However on two occasions it (or BEACON_RATOS_CALIBRATE) has now moved the head to x=400 before doing initial approach. First time was as part of BEACON_RATOS_CALIBRATE. The second time was when running it explicitly. The first time this happenend, I believe the y was also set to 400, since the head moved to the very back right corner. In that position there is nothing that beacon would detect, so the head crashed with the bed during the initial approach. The second time y was at 200, so perhaps beacon would have stopped, but i switched off the printer rather than wait and see.
What might cause this? An uninitialized variable somewhere? ...
Solution:
Missing G90. You're in relative positioning, so you've already homed and have moved the axis around with the mainsail toolhead dialog (which sets relative positioning)

4028 fan does not stop completely

Because my original 4028 died some days ago, I installed a spare ARCTIC S4028-15K fan and connecte d the PWM to the toolboard as normally. Now... I can set the speed as expected, but the fan does not stop completely. The fan is turning really slow but it´s turning even in Fluidd/Mainsail it´s set to 0. Any idea how to fix this issue?...

RatOS homing behavior

Hi guys, I recently swapped to RatOS, just wanted to ask what the homing behavior is supposed to look like, since when I homed last night, the probe was left hanging out of bed in the front left corner and the bed crashed like hell 😅
Solution:
thanks for the suggestions! Turns out sensorless homing was off a little, so sometimes it homed correctly other times not as much, so it was acting wonky.

Move exceeds maximum extrusion (2.673mm^2 vs 0.640mm^2)

Trying to print some basic stuff and getting the following message: Move exceeds maximum extrusion (2.673mm^2 vs 0.640mm^2). Nozzle in slicer is 0.4 as well as in RatOS.cfg file. The print stops during prime blob, so i think it is not related to sliced file. Any help are more then welcome...

RatOS 2.0 upgraded to v2.1.x - Custom V-Core 3.1 with Etched Foil bed heater w/ 3 combined sensors.

Hi everyone, I'm running a modded V-Core 3.1 AWD that was working great on RatOS 2.0. But after upgrading to 2.1.0-RC2-106-g8614d79, my custom bed heater setup stopped working because of a conflict with an existing parameter. The Etched Foil heater has double thermistors (named as "bottom_x") and the 12mm alumium plate has another one in the top. As the whole bed system/ arms are metal I am able to heat the heater to 180C (on the bottom) without problems, so that allows me to get the desired temperature in the top much faster than usual (usually 105C). ...

I'm confused about which version of RatOS to download.

I have the RatRig V-Core 4.0 kit with the OEM Raspberry PI 4 board. Which version do I download off of GitHub?

Beacon Rev H - Will not pass calibration. What is wrong?

Doing the configuration. Everything starts out fine.. passes then gets to the last part... throughout when it is outputing latencies, it is 1-3... all of a sudden at the end.. its now 4,5,6. It is doing the final sampling (from right top corner).. I get sample readings that are ridiculous.. I have went and checked the z rod couplers... if I am reading it right, I push them down and tighten to the stepper motor shaft... and there needs to be a space between the stepper shaft and the bottom of...

RatOs.cfg issu

Heyy i have the problem that if i change my ratos.cfg save an restart the canges are right If i turn the printer off and power new than the canges are gone. Did anyone know why?...
