ok good morning YouTube just wanted to show you my latest set up here so I picked up this 20 by
4 liquid crystal display and controller for 3d printer and I was thinking I could add this on
to my series 1 pro printer which does not have a display so I found out in the Marlin firmware
that gets loaded into this rumba controller board that you've got to build in the support
for various controllers and enable the various definitions to get that code to compile so I've
been waiting for my rumba board to show up and it did and so I took the Marlin firmware
that Taipei machines released and compiled that except I enabled all the code for the
20 by 4 and I downloaded over the USB port and there we go there's the code running so you've
got your I guess that's the bed temperature the extruder and then you've got your XY and Z as
far as the hook up your SD card goes in here and then the liquid crystal LCD display goes
over in this position what I've got is a 12 volt battery supplying power right here and
you have to change this jumper right here if it's in the bottom two positions you have USB
power and if you have the upper two positions you have what they call standalone power and
that's what I'm running on now one thing I can do with this right now so I've got a
little 12 volt fan plugged into the controller so let's go over here again those control and
if we go temperature and speed and we'll go up like that now watch you got a fan running
all the way up to 255 down to zero so yeah I think everything's working there so this code
in here also has the auto bed level sensor code enabled for the series one Pro I've installed
the hardware but see I think my plan is I want to try to rebuild this Marlin firmware here and turn
off the auto bed level sensor code for now and then just see if I can get the display controller
working just by itself without adding the bed level sensor code so I found the sections where
the LCD an SD card code is enabled so I know how to turn that on and off now I need to find where
the bed level sensor selections are done so I can turn that off because what I like to do is
build a version of the Marlin with the 20 by 4 LCD but no bed level sensor be able to build
that upload it to the printer and make sure that this works and then I'll try doing the bed level
sensor update as I figure if I start trying to do two things at once I might not know what exactly
I'm doing but yeah the SD card works here if we go in here I can go down here and I've loaded a
file on the SD card and it picks that up yeah that's that's pretty neat got a fan so I guess
that's off a fam number one there so I've got all the stepper motor controllers and then this
kit comes with most of the connectors you need you know the two things I have to do one is I
have to figure out how to turn off the proximity sensor auto bed leveling code in here I'll test
that again I need to figure out how to get this firmware loaded on my printer that's up in the
attic I don't have a PC up there I can find my old XP laptop so I'll have to see if I can get
the arduino ide and the USB drivers loaded on XP which i've seen that it's possible so I just have
to go through the procedure to do that and if that works and I can just use my laptop to program the
rumble board in my series 1 Pro with the firmware that I'm running here this way it gives me a test
pad I can check it out make sure it works before I go and burn it upstairs and brick my series 1
pro I'll bite the bullet and try uploading this and then see if I can plug these two connectors
into my series 1 Pro and get this display working on that printer because I think that'll be pretty
neat just having a control panel right there on the printer because that's the one thing
the series 1 Pro does not have it doesn't have any sort of front panel there's a power switch
and that's it I wouldn't have to get a Wi-Fi connection and you know wait for the interface
to load and all that stuff because that takes a few minutes every time you turn the printer
on versus this is just right there you turn the printer on as soon as this thing boots you can
adjust things you don't have to wait yeah if you have any experience building the Marlin firmware
and know any neat tricks to do there you know post up in the comment section below and I'll keep you
posted any update videos I'll put over here on the left side and as always thanks for watching
