Github Bigtreetech Skr Mini E3
Maximilian Lozano
I checked. There is a printer-creality-ender6-2020.cfg and a generic-bigtreetech-skr-mini-e3-v3.0.cfg. I am merging them. But I was hoping to find someone who already had it working. This is my first Kilpper install. I have been using Marlin for the past 5 years.
I am new to Klipper so I decided to get the SKR Mini E3 V3 working with Marlin 2.1.1 first. It turns out the Ender 6 is actually a CoreYX machine, but I discovered this AFTER I got a working configuration.
AND I had to reverse the X and Y stepper plugs on the BTT controller. If I had specified COREYX it might have been easier. I had to flash the firmware about six times to get a working combination!
I got the same configuration, an Ender 6 with BLTouch installed using a BTT SKR E3 Mini V3.0 with BTT TFT35 V3.0.1 under Marlin 2.1.2 and have some trouble get it work correctly, maybe you can help me a little bit.
It took me about 2 Months to get the Marlin 2.1.2 firmware to work. Today I made my first few testprints, tried to print a Benchy. My issue is the writing on the first Layer of the Benchy is upside down. Maybe it is while I have other settings in the configuration.h as you.
Hi rtremmel,
I made now the changes, inverted the stepper cable of the X and Y axis, and got the printer to work again, but I have the same issue. If there is a writing on the first layer(s), it is printed mirrored, and so not really readable. I have been at this point before, without inverting the cable of the x and y stepper.
That said, the Ruida Controller for an RF fiber laser would be a known quantity. The manual for that model of controller may offer insights to all the power supply control parameters. A list of pin-outs and signal ranges would be a great way to start.
Looking at the bigtreetech github repo and quite optimistic about the SKR Mini 3.0. Klipper might present atypical challenges.
bigtreetech (BIGTREETECH) GitHub The pin-outs are published which is great. Another GRBL variant may be more accessible.
Karl here with a quick upgrade guide. The one complaint I had in the review of the SV01 3D printer was it was loud. Today we are going to look at resolving part of the problem by replacing the Creality board with the BigTreeTech SKR mini E3 V1.2 control board sold on Amazon for around $37. Fan noise at a later date. This board is ideal because the SD card, USB, and screws line up for nearly a perfect replacement. I did not bother hooking up the filament runout sensor. I have never found them particularly useful and always ensure I start with enough filament and bypassed it for the review. The board comes with TMC2209 drivers which significantly reduce the stepper motor noise as well as stop any salmon skin.
All the below connect is not necessary. The screen has an exp3 connection on it with the correct pinout for the SKR mini E3. Take the connection from the E3 on the screen to the 10 pin connector on the board. No splicing necessary.
While reading the article, I was thinking that I would have chosen to make an adapter instead of alter the motor wiring. I like to leave myself the ability to back out of any changes. Maybe from too many years as a sys-admin?
I have done some more tweaking and github is updated to reflect. All the advanced features are turned on now. It really does print amazing. Linear advance with a setting of .2 for my machine. If you think I should turn on permanently let me know.
While the modifikation of display cable is not necessary, I like the information as I intend to change to a skr touchscreen with 12864 emulation. It does not have the special Ender3 connector, so the description is very helpful.
One point for z:
As far as I know, two stepper motors should not be put in parallel if it can be avoided, but in serial. While on 12v there is nothing else than parallel possible (so parallel connecting is very common) in 24V you can connect the steppers in serial.
