Milo 1.5 CNC - LDO Kit

[mvdveer]

Electronics and Wiring:

Followed the excellent guide from LDO for the electronic layout and wiring.

BOM:

  

Flashed a 64GB Samsung SSD with Millineum OS and RRF v0.3.0-rc1. Formatted the card in OSX diskutility and used ExFat (Choices were MSDos, ExFat) - Don't!

The Fly controller board does not like it. Flashed in command line with Fat32 and all was good again. (This can be achieved in OSX diskutility by choosing MSDos - will revert to Fat32 if disk is larger than 32GB)

Connected successfully, changed WiFi and continued to install the electronics.

     

Had to reprint the front skirts, as I chose the wrong panel to have the Emergency switch mounted as per LDO wiring.  The wiring took most of the day. Powered it up and "no magic smoke!"

 

Now to figure out how to configure this. It has a configuration macro that comes up with a spindle by default, which is not the one I have, and I cannot seem to select one. Have some reading to do.

Done all the prelim checks. All end stops working, All axis homing. However, got a problem when doing a home all - RRF through up an error. As this is completely new to me, will have to do a bit more studying prior to actually knowing what is happening. Now need to get the equipment to tram the work surface.

Watched some youtube videos from West3D on his build.

Updated the RepRap firmware and Millenium OS. Ran the configuration wizard and what can I say - pretty happy with myself.

And you guessed it - my probe is on the way.

Machine homing successfully:

 

 

 

Now I got to learn the lingo to get GCode generated in Fusion so I can make some CHIPS!

Congrats on the build awesome build guide! Can I ask how do you post a video within the post on this site? Every time it tried I'd only get the link.

Thanks Jack. You were the inspiration for this build.

I had to convert the video to mp4 format, then just uploaded through choose files, and inserted into the post. The you-tube video embeds itself when you copy the link into the post. Hope this helps.

I have all the BOM (self sourced) for the CASA enclosure, excepts the panels. Glad I did not order those as they have changed with the latest release.

I may start the build on this whilst waiting the probe for the Milo 1.5 to arrive (2 weeks according to Aliexpress). I

n the interim, I am trying to figure out how to install the post processing scripts in Fusion 360 in order to "slice" a file to mill. I have a source for some off-cut pieces of aluminum, so I am keen to give that a go. I know most folk do their first cut on wood, plastic or foam - but I am a proud "Friesman" (Frisian), so aluminum it is!

Will have to do a cut, and post a video in order to get a serial and who does not want a serial?

Nice! Congrats!

It's not for celebration.

It's so he can destress better when he is alone 'working' in the printer room

The fixated plate was sitting loose on the extrusions.  Searched high and low for the stl but could not find "clamps" to fix the table to the extrusions, other than ones that need to be milled.

So I put my limited Fusion skills to the test and modeled some.  The holes are offset on purpose to accommodate for the cable of the Long John tool-setter. They are fixed with M5x18 BHSC.

  

I have uploaded the step file and fusion file if you have a need for it.

Started on the CASA enclosure. Boy is this thing BIG! Had the frame assembled and then realised I got not get it out of the door. So building it into halves and will assemble in it final resting spot. Did the drawer mod on this. There is no manual, so the build is completely off the CAD. And.... it uses a hell of a lot of M3x10's (about 400) and an equal amount of M3 roll in nuts.

The panels are 3mm Aluminium composite and the parts are all printed in ASA. 

Progress so far on one half:

Electronics bay: (Unpopulated at present - awaiting delivery from RS-Online

  

Front with Drawer mod:

Basement and Chip trays:

Now for the other half............

 

[PFarm]

@mvdveer Nice! Is the drawer mods online, I like that idea. I'll need to extend the dimensions on X & Y for the additional length of my stepper motors. Plans are to move the water-cool components to the electronic bay on the enclosure.

Yes they are. Here is the link.

There is also a Rear Bay Mod which I have not explored as I won't have access to that part of the enclosure.

[mvdveer]

Did some more work on the CASA enclosure. Fitted all the ACM panels and completed the electronics bay. This is a build in two halves, as I am constructing it indoors and then moving it to its final resting place in the shed. (Has to be two halves as it won't fit through the doors otherwise). Did the rear bay mod to fit the air pump, now that it is going into the shed, and Will have 360 degree access.. 

Once the enclosure is transported to the shed, Milo will be housed inside. For now, being winter (and a miserable one here in Melbourne), I am content in just pottering along with the build in my study. (Just hate the mess in the study because of this thing)

Replicated all the electronics in the electronics bay and wired all up to the controller boards.

                        

The cabling will all be terminated into a connectors that I am going to install on the inside panel of CASA. Another set of connectors will be installed on a panel on the Milo machine as well. The idea is that Milo will be able to either operate inside CASA, or be taken out and operated independently outside of CASA, by just unplugging and plugging in the panel connectors. (Why? - just because!)

Aviation plugs for VFD power and JST panel connectors for endstops and motors:

                    

Electronics bay has a removable cover, so easy access to the electronics bay if needed. Very crude handles quickly designed, just to get the cover on and off for testing purposes. Will do a better job at these - more slimline one's to come.

 

Wiring from electronics to plugs to the inside of CASA (Where Milo will be mounted) completed.

Till the next episode...............

Nicely done! So you'll be disconnecting input and outputs from the "Milo" motherboard and splicing via JST connector into the existing wiring feeding the end stops and steppers? I see you've kept the VFD mounted on the Milo so the power source is fed to either the Casa or the Milo. Awesome work did you model the JST bulkheads in the Casa enclosure?

No I got them of printables - link here. you have to go into fusion 360 and "assemble the configuration you want" . Also just saw this on discord - similar idea.

Exactly. The same configuration that is on the Casa side panel will be on the back of the milo. So if I remove the Milo fro CASA, I just plug the onboard electronics into the connectors on the Milo and vice versa.

Did you drill the 2020 yourself using the drill guides? I'm assuming guides match up with the "letter" 2020 extrusions not much explanation in the assembly documentation.

I love this idea of being able to disconnect  electronics from the mill, I'll be using it in my enclosure thanks for the link and idea!

No, When I sourced the extrusions from Ooznest, (with postage was cheaper sourcing from the UK than buying locally)  I had the option for them to be drilled as well. Took the lazy man's way out and had the blind joint holes drilled and extrusions tapped. Still had to drill some holes, and used the guides for that. Just matched them up with the extrusion - Drill guide A1 - A4 for A extrusion as per the BOM, D1 -D4 for D Extrusion etc

I have a question regarding a few parts in the electronic bay file, I read through the assembly manual, and I can't find any reference to these parts. Did you install this in your setup?

Those are for installing LED lights if I remember correctly. Printed them but did not install them as I printed the diffuser in black ABS and could not be fussed to load the clear/transparent ABS and reprint.

Will look at a different solution for CASA lighting when I revisit the project. It is now housed in a shed and the Melbourne weather is terrible, thus have not been down to the shed to work on it.

[PFarm]

I've read that the VFD suck in aluminum chips into it. I found this LDO VFD Exhaust Hood on Discord. Supposing you're leaving the VFD in its original location. You may want to print this for your mill. I've modified the step file to fit my 2.2kw VFD.

I used the LDO LED clips and SK6812 from BTF Lighting for mounting in my Casa. I increased the size slightly in Super Slicer to 101% for a tighter fit into the 2020.
