mini Kossel Calibration using Repetier FW
HTML-код
- Опубликовано: 5 окт 2024
- This is a step by step process of calibrating your mini Kossel and other delta machines using Repetier firmware and host software. This is the initial calibration. If you are using Marlin, you can convert these instructions to work with Marlin, but using Repetier FW at least for the initial calibration will save you many hours of editing the configuration.h, saving, compiling, uploading, connecting with host software, testing, and repeating this cycle over and over.
In future videos I will show how to fine tune your calibrations, how to calibrate your extruder, and your hotend.
Omg this is the best video ever. Before I watched this my z axis wasn't even working. I have more calibrating to do but thankyou so much.
Josh Bragg You are welcome. I have some blog postings at reprapandme.blogspot.com too.
Great video, really helps understanding these delta printers!!
Outstanding.. Great work. I will be looking at this when I build my Kossel Mini. =)
you are the machine! thx a lot.
Brilliant video by the way.
Flatness can be done working on one axis only.
First make sure to calibrate the 3 axis so they are as level with the bed as possible.
Then choose one axis, measure the error in Z near your axis and at the center of the bed. If the difference
(Z reading near axis) - (Z reading at 0) > 0 --> increase ROD_RADIUS
(Z reading near axis) - (Z reading at 0) < 0 --> decrease ROD_RADIUS
You can use decimals and be very precise. No need to zero the bed between readings, as the machine is already even. You may need to repeat the operation many times. Set zero when done, use the printer height. Adding or subtracting the same values to all endstop offsets will keep the bed level, if you want a nice round value for the printer height.
+tikabass With due respect, the method I show works as-is and you are welcome to create a video of your process. It works so well, I have not had to recalibrate unless I changed a physical part of the tower axis.
Jay Couture No problem with your method, I rather enjoyed the video, and it was really useful. Thanks! I'm just pointing out a shortcut, which I found while using your method. It's much, much faster, especially if the printer doesn't have an eeprom, since each parameter change requires a compilation and download of the sketch.
I typo happens at 19:52 in the video with the G code command I show in the G-Code entry field. It should be G1 X-69 Y-40 Z10 F4800. I have added an annotation (if you have them turned on) to fix this typo.
Hey jay, thanks for tutorial, it helps me understand repetier firmware more, and i'm using repetier in my new kossel mini, but i still having an issue with the nozzle height when it moves along Y axis, when i move to X0 Y70 the nozzle still crashing into the bed, i've calibrated all the endstop,and the horizontal rod radius, do you have any idea what might be the problem? thanks :)
a copy of your configuration.h would be awesome.. last tree days trying to get right my setup!
Per your request I have added the most current configuration and EEPROM values here: github.com/Jaydmdigital/repetierfw_files
One other thing, that configuration.h does not have the LCD enabled (I don't have one on that printer). You can use that file and the Configuration tool I linked in my reply to gerol and select the LCD to add it.
Would doing this process in reverse work? Like get the correct centre height and then calibrate the tower endstop offsets?
Thanks for posting,
I'm on the last step where you adjust the horizontal radius from the center of the nozzle to the tower. I'm only off by.3 but no matter how much I adjust the number nothing changes. What gives?
Alvin Thai You adjust the number, then recalibrate towers X, Y, and Z and you are saying the center height does not change too?

Hi Jay, this video is really helpful. Thank you. Is it possible to send me the complete repetier firmware files? I am using different version that does not support offset correction.
www.repetier.com/firmware/v091/ and read my blog post reprapandme.blogspot.com/2014/02/repetier-firmware.html
Jay Couture Repetier configuration tool works like charm, thank you thank you!!
do I need arduino on my computer to use repetier software and EEprom is not highlighted can you help?
+David Crandell To burn the firmware (Repetier, Marlin, etc...) yes you need Arduino. Did your controller (I'll assume RAMPS) come with a firmware pre-loaded?
You do not have kossel_300.scad file in that link. can you post a link as soon as possible because i am too working the project i feel that your method is easier.
kushal penugonda From the github comments: "Removing the original calc file and replacing with one with 1515 in the name to make it more clear." Use kossel_1515.scad
Hi Jay.
I'm using Repetier V1.6.0 andIt seems very limited re the eeprom settings, I don't have most of the options that you have like diagonal rod length etc etc. is there another view that can be toggled?
+Motorwinter I have not used Repetier since v0.92. I primarily use Smoothieware on an Azteeg X5. However, I hve not use my mini Kossel in a year so I download the new Repetier and see what I can figure out what changes have been made.
+Motorwinter Ok, just installed ver 1.60. The Alt-E option is there in Repetier Host and all of the same variables are visible. Do you have EEPROM enabled in your configuration.h?
I do indeed Jay. So I press alt + E in repetier and it witt toggle that view of the options.
Your instructables are great. Thanks Jay.
no my ramps 1.4 board didn't come with pre-loaded firmware.
+David Crandell Ok, then you'll need to download the Repetier firmware, configure it, and then upload it using Arduino software. my blogpost may help with configuring it and keep in mind this was written 2 years ago. reprapandme.blogspot.com/2014/02/repetier-firmware.html
Just to clarify , you don't need to do all this manually when you have an inductive z probe for auto leveling Or do you?
Ideally you wouldn't. I never had much luck with a probe, and so I created this video (and others) to detail the process I use as a resource if others wanted to do the same thing. I only have had to calibrate once and until I changed anything physical (hotend, printer parts) I just turn it on and go.
How do i Get My Kossel To Auto Level It Self? i Have A Sintron Kossel Mini. And I Have Not Installed anything onto it. it has menus and stuff but, i dont know if i need to add firmware or software. I just Want to know if i can autolevel and print right now without adding any stuff on to it
Been away from the scene so I am not familiar with that model. You will want to see if that maker has a forum specific to their machine/controller. Hopefully they have a quick start guide too.
Jay Couture I Figured Out It Does Indeed Print When I Put In A Sd Card In With G Code on it, Now I Am Trying to install repetier firmware, but i want to use the auto bed level feature, with my z probe, but it asks me to define a pin on the ramps 1.4 board in the setup. I Have Everything Built And Wired, But I Dont Know What the pin number is or name i have the z probe plugged into. once i get the name of the pin i wil be able to define it then install the new firmware
good
Hi. Thank you in advance for this video. I calibrate the 3 points well as in your video. I came to the origin and saw the end of the hotend above the bed. I decided to change horizontal rod radius in EEPROM Settings but it does not have an effect on calibration. Why? What's the problem? Please help me :)
+Samet AYHAN Have a look at reprapandme.blogspot.com/2014/02/irst-tests-and-calibration-repetier.html
+Jay Couture Ok. I will look at it. Thank you for your rapid response :)
Same issue. were you able to solve it ? @samet ayhan
My kossel printer is not alive now :D I diassembled it. I am fed up with calibration stuff of it. I am going to build an cartesian 3D printer.
I think you are confused about one thing. After you calibrate the outer points and determine the center is too high or too low, you have to modify the delta radius then re-calibrate all of the outer points again. time: 33:51 states this.
Arduino: 1.6.0 (Windows 8), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Error compiling.
What do i do?
(the same error is repeated multiple times with other things)
What firmware?
Repetier
It should be the same as yours
please help i dont know whats going on! re installed the firmware and got this:

Actually, I'm using Arduino 1.0 and Repetier 0.95. Based on the errors Id point you to trying an older version of Arduino first.
