on today's makers mashup an update to the
skr2 welcome makers so on today's makesr mashup we're doing an update video to the skr2 i've got
one right here and it's brand new in the box i haven't opened it but i wanted to do it first
for you guys uh what i've got here is an skr 1.4 on here and we're going to be taking this
board and putting it on the test bench now if you're not familiar of the skr2 issue there's
a card up at the top but basically i did a first look video big tree tech reached out to me they
said stop using that board there's a serious bug in it and that bug was that all of the tmc 2209
drivers in the board would completely fry had i turned that board on but i did not uh but i've got
the replacement board here it's brand new we're gonna put it on the bench we're gonna test it out
fresh and hopefully it won't fry my 2209 drivers so stay with me here we're gonna check that out
right here and hopefully i'll be able to give it a thumbs up so with all that said let's get to work
okay so here we have the skr2 and we're gonna open this right up here for the first time
cable and the duck and we've got this completely unopened we're going to open this up
all right so now we've got our skr2 open and i'm going to need to pull these jumper pins
off here so that way we can put our drivers in
all right so now we've got the skr2 set up we're going to remove our skr14 from our test bench
so here we have the 1 4 and the skr2 side by side
and these are the 2209 drivers we're just gonna take them off our 1-4
and now we're going to install these 2208 so we've got mixed drivers that we're testing out here
all right so here we have our board with the drivers installed i'm just going to
check that we're set for external power let's hook up our set up our leads here the board
and then i've got here on my sd card the firmware supplied by big tree tech
so we're just putting that in there remember these don't have the spring-loaded mechanism so we're
just going to push them in there and then we're going to hook up a couple of steppers then last
but not least we'll screw this in and install the display and we'll be ready to run our test
okay so we have our skr2 installed here and then we're just going to hook up the display
and then we'll turn this on for the first time and hopefully we're not going to let
out the magic smoke all right so power supply hooked up steppers our step sticks in the proper
configuration and we have our sd card and we're ready to turn this on for a unit test
and there we go we're getting the marlin firmware display here and it's asking to initialize the
eprom which we'll tell it to do and then let me pull this forward a little bit so you can
see the steppers let's try to move some of our steppers here and make sure that they are working
there we have it stepper here is moving just fine so big tree tech has indeed fixed this problem on
the board all right so as you can see we installed the skr2 successfully we were able to mount it
to the test bench and it did not fry any of the steppers and the steppers uh turned just fine or
i should say didn't fry any of the step sticks and the steppers work just fine so i also want
to go ahead and say thanks to big tree tech for sending that replacement board out right away it
was great you guys were able to see my video and let me know before i'd actually fried that other
board and i was really glad to do and a couple of update videos here just showing that you guys
do have that fixed now i do also want to say to big tree tech if you guys need more help testing
it would be much better if these things were tested a little more thoroughly out in the wild
i know myself i would personally like to test it and i also heard that uh thinky head did not
actually have an skr2 in hand when he was working on the marlin firmware so
that was uh in some notes in uh github so it would be really great if you were able to pass
those boards along a little bit more so that way people can get these tested in the wild so
we're certainly ready to help you guys with uh anything that you need us to test just got to
send those boards along so that way we can save a lot of makers a lot of frustration but thank you
again for reaching out uh right away and getting this done and uh restoring my faith in your
skr2 board so thank you i also want to say if you want to send that new octopus board over
i'm more than glad to test that one out for you too we can get that installed in an x301
and see how that's working as well so please feel free to send that over anytime uh and then if you
are interested in this test bench you can build one of these yourself
and i'll have a card at the top here that you can go ahead and follow the link to that video
it's really about din rails but it shows how you can make this test bench it's really
great for testing out new main boards and things like that and maybe some of the big tree tech guys
build one of these for themselves so with all that said i want to say uh thank you guys for
