Milo V1.5 CNC Bench Mill - Water Cooled - Casa Enclosure

[PFarm]

Coming from the installation/service industry I would drill into my installer to think about the positioning/orientation of the components and ask yourself if it is easily serviceable. My original location of the radiator was at the back of the Casa enclosure. With little room to spin the enclosure on the table, it was awkward to access the radiator should it need to be serviced for any reason.

I relocated it on top of the enclosure which is much easier to access. The only drawback is having to route hoses and wiring to this location.

 

I removed the 1/8" mounting plate I had fabricated for the tool-setter and drilled and tapped the Milo fixture so I could mount the tool-setter directly to it.

Casa is ready for the Milo Mill. Those are joiner strips that you see this way I could use the leftover 2040 that I had on hand.

Installed the enclosure LED's

The E-bay LED's as well

[PFarm]

I'm trying to set up the LEDs in the e-bay; this is what I have in the RRF system. I'm having no luck powering the LEDs. 5V comes from a separate power supply signal and ground connected to Neopixel port. Do you fellows use RRF or Klipper for your VZBot? I tried to get help on Discord but no luck there.

Update: turned out that the 5V—power supply when metering voltage to the neopixel ground pin was only getting 1.4V. Wire the 5V neopixel wire to the port 5V. and all is good.

Sorry am in outback Australia with limited internet connection. Glad you got it sorted.

@mvdveer All good! In the outback for work or pleasure?

Pleasure. Was time for a break and had to put the new Raptor through its paces. Will be back in civilization in a few weeks. 

[PFarm]

2020 hinges came in today so I could install them on the doors. Picking up the Poly for the doors this weekend. @mvdveer Raptor very nice ride! Enjoy your time off mod master!

Quick fitment test. Still waiting on rockers switches.

[PFarm]

All components on the Milo are wired except the 220V, Spindle Enble, and Spindle Speed. Should have the mill inside the enclosure tomorrow

Going great guns. Well done

[PFarm]

I'm seriously considering purchasing the BTT Rodent motherboard. I've researched Fluid NC and it seems easier to program slightly more complex functions.

The config file looks more like the Klipper config file which I'm familiar with compared to RRF.

Milo is inside the Casa enclosure. I need to complete a few electrical connections and plumb the water cooling system. Then ready for start-up and trimming. Measure the X travel to the right and the Milo needs to move at least 10mm to the left.

[PFarm]

The Milo has some movement, the z and y homes smoothly. The issue is with the X-axis the stepper is loud. I think I've set the backlash too tight. The other issue is not homing correctly. I'm going to reset the backlash and rewire the stepper.

The BTT Rodent was purchased and it was shipped today.

[PFarm]

Well, this sucks  the Mellow Fly CDY V3 board stopped communicating with the SD card. Tried a second SD card with no luck, and tried to re-install the firmware but this confirms the no communication it will not load the firmware.bin. I guess I'll need to wait for the BTT Rodent to continue testing.

An interesting tool changer works without changing your spindle. However, a rewiring would be required to use this with the Milo; an additional wire is needed for the spindle to run in reverse.

Looks interesting

LOL, it's barely almost-complete and already looking at mods.

Yeah, I have a hard time keeping anything stock  . I'm glad I ordered the BTT Rodent since the Mellow board bit the bullet, and I like what FluidNC has to offer.

A couple of plaque for the Casa.

[PFarm]

My side project for the Milo, since I'll be using FluidNC I'm building this pendant.
FluidNC Pendant

M5stack is only $50 CND and a couple of momentary push buttons are $3.50 from Aliexpress.

[PFarm]

I printed the pendant case. If you want to print this, note that the step files listed on GitHub are completely different than the STLs they're for CYD pendant. What I've printed here are modified step files the bottom base is extended to accept the 19mm switches and the top switch holes are to fit the 19mm switches. Coloured rings have been modelled. The momentary button switches I've ordered have coloured LEDs. With Canada Post on strike not sure when these two projects will move forward.

 

[PFarm]

Received the MS5Stack and programmed it with PlatformIO. 

I salvaged an old keyboard accordion cable that will fit this project perfectly. I need the momentary button switches to complete the pendant.

[PFarm]

I soldered the wires to the 4-pin connector for the pendant connection to the BTT Rodent motherboard when it arrives.

[PFarm]

I purchased the momentary switches and rockers switches for the Casa from an electronic store in Montreal, Quebec an hour drive from home. Use a 4 pin 2.0 JST for the wire connection on the MS5. I needed to remove lock tabs so the connector would fit. Once I confirm the operation of the pendant I'll glue gun the connectors in place.

I've installed heat shrink over the 4-pin connector. Momentary switches are wired and installed.

 

[PFarm]

I modelled a din rail mount for the BTT Rodent, Mellow Fly CDY V3 for size comparison.

[PFarm]

Since all the electronics have been transferred into the Casa enclosure, I've printed these two solid skirts from two different ABS leftover spools.
