I'm hoping there maybe someone who van help me make a start on installing the firmware on my board which will be running a cnc mill please.

I love new technology but struggle finding supporting literature that makes for straight forward instruction.

If theirs anyone who can get me started be very much appreciated.

The print turned out pretty nice.

MGN15 rails, Nema23 motors, 5160 drivers.

Following the Voron ethos - all parts readily available. Kits - no full kits as I understand but kits containing the aluminium parts.

Here is a video:

The board is ordered and I'll update the process when it arrives.

Here are some useful links

Milo Pendant

They've done a nice job of making a single circuit board from all the components needed in this mod and flashed the Arduino with the pendant software.

I will change the cabling to the Scylla motherboard and add a strain relief to the pendant case. They could have made a better effort in that aspect. I'll also confirm the wiring to the Scylla I/O connector when I receive the pendant.

Safety interlock:

• One microswitch is wired in series with the enable wire going from the Scylla control board to the VFD. This keeps the spindle from spinning up with the spindle lock key in place.
• The second microswitch is wired to the Scylla Z-min endstop (input), so a message shows up in the GUI reminding the operator that the key is still in place.

3D printed the components for the mockup, found that I need to add 2mm to the top ring so it sits flush against the spindle.

I need to model a new mounting plate for my 80mm spindle LED's.

Now to machine these components in aluminum. 

Hello everyone,

When assembling my equipment with a NEMA 17 planetary gearbox, I found that the output shaft has several locking methods, including set screw locking, clamping ring, and keyway.

I'm using a synchronous pulley load, the speed isn't high, but it needs frequent starts and stops. I tried set screw locking, but it occasionally loosens after running for a while.

I'd like to ask everyone, what are the suitable operating conditions for different locking structures? Which one has higher reliability in long-term operation? Are there any installation techniques to prevent loosening? Is it necessary to use threadlocker?

I hope friends with practical experience can give me some advice.

Millennium Machine Milo V1.5 Mill is a relatively new and not much information is available for this mill. The purpose of this post is to provide information for the Fusion 360 tool library and end mills for new users like me.

The LDO Milo kit does come with a LDO CNC Starter Kit, which contains the items shown in the photo below:

Before getting into the end mill settings, here is some useful additional information for you.

Milo Z's column lacks the stiffest as your commercial mills. The workaround for this is operating the mill at a proper feed rate per tooth. Ideally, the setting should be 0.05. This can be accomplished by adjusting the Spindle Speed and the Cutting feedrate. Please take this info for what it's worth, I'm new to milling, and I know there's a lot more to this than I presently know, but I'm posting the settings that I've set and worked for me.

You can see below that changing the Spindle Speed and the Cutting Feed, the Feed per Tooth is increased.

Another important setting in the "Manufacture" section setup of Fusion 360 is that when using 2D Adaptive Clearing is necessary to set the "Optimal Load" at 10% of the tool diameter. In the example below, it's set for a 6mm end mill.

It's recommended that a proper tool holder be used in the tool library to avoid possible collision when milling a part. Here is the link I used to import my ER20A collet into Fusion 360. Keep in mind that I've installed a 2.2 kW water-cooled spindle on my mill, but the LDO comes with a 1.5 kW spindle, which uses an ER16 collet.

Two of the most used low-profile hobby vises are:

Inception is made in the UK - Inception Site Link

For USA/Canada West 3D stocks the vise - West 3D Site Link

The other is Saunders Metal Work made in the USA - available in two formats, 1/4" and M6, which refer to the size of fasteners and spacing of the hole in the fixture plate. There are two generations of these vises: Gen 2 sold before 2025, Gen 3 sold in 2025. Parts are not interchangeable; both the complete vise assembly can be used with either generation. SMW Site Link

Note: Both sites have CAD and CAM files available for download. I do not own an Inception vise, but plenty of hobbiests have installed them on their Milo. I do have the SMW vise and am very pleased with its function.

Features from the Milo V2 have been implemented into Milo V1.6. Purchases of additional parts have been kept to a minimum using the existing V1.5 parts. There is an upgrade to ballscrews if you so desire. 

Feature/Changes:

• Two mounting plates are used to mount the spindle to the Z column. This makes tramming much easier.
• Tramming aid tool
• New X/Y mounting plate
• A thrust bearing is used in the bearing blocks of the axis
• A new floating bearing assembly with the 608ZZ bearing
• Z motor mount is now direct drive
• New Z bearing block
• Drag chains have been routed from the rear of the Z column
• New Y-axis bearing block
• New Y motor mount
• Y Y-axis way covers
• New Y-axis hold-down printed parts
• Y axis homes toward the Z column
• New antibacklash nut assembly, still uses the brass TR8 inserts, and a spring washer is added to the assembly
• As mentioned, ballscrews are available

Watch Jake England on YouTube put a Milo V1.6 together for the first time.

I'll be upgrading my Milo to V1.6 and will document it in here.

Today, I spent some time learning CAM in Fusion 360. For the record, with the personal version of Fusion 360, the tool change requires a separate operation. First part is going to be the Fixature Clamps, a F3D file is available for download with the CAM operations. It's great to test your mill operation, but not much of a learning experience.

With my CAM setup, I wanted a different parts orientation in the vice, plus my stock was 25mm x 25mm instead of the 20mm x 10mm. Tomorrow I'll upload the files to the mill and we'll see how it turns out.
