Hi Neil, great work; now stop teasing us and show a video in operation, I know I will definitely get a thrill while watching, I might even get a little sticky! 
āAJAā
Neil, youāve produced something really special so kudos to you.
Regards Jerry 
Hi Jerry,
Thank you, here is a short(ish) video of chips flying from the 40mm cutter, although donāt want to push the plastic gears in the machine too much, they are only rated for 20mm dia milling max. Once the belt driven Brushless ODrive is on there it will unleash the beast from within 
The video is unlisted so wont show up on YouTube search and there is no audio for the first part as my children were super noisy (louder than the mill 
).
Kind regards,
Neil.
You are the cnc jedi Niel.
Iām amazed with your skills and design.
Take the compliment! 
Thank you Quintin.
High quality parts, I now get 
Very nice indeed, and I love the enclosure. Does it have a door?
It seems to keep most of the chips in, too! I bet your wife is āimpressedā 
(iām amazed that you havenāt been evicted to the shed! 
)
Whatās the contraption next to the air pump? Is that your battery/inverter for the solar stuff?
Are you using that like a UPS? How long can it run off the battery?
I bet it will be a lot more efficient when you replace that induction motor too! 
Iād be quite interested in buying some bits off you for my mill, when you have the time to make them! 
Hi @towen,
Yeah, the full front is a door, making a video at the mo of how I made it, should be out in the next few weeks.
My wife and kids love it, think my wife is a secret engineer as she suggested it came into the lounge to prevent it rusting
The device is a 1000W pure sine wave inverter from Bestek (not Bestech, edited), it uses 1A itself so does increase the drain on the batteries. The spindle motor, cabinet lights and chip blower pulls around 170W in total, where the Z and X axis drive pulls around 1A each when moving at full chat. So all in all on the 75Ah battery from full charge lasts around 4 to 5 hours, although Iām only getting a low charge from the 50W solar panel with the UK sun, so running the spindle motor from the wall at the mo (although I am with a 100% renewable energy company for home energy, so still green).
I have used it as a UPS on the computer when video rendering during a power outage, plus it was running our fridge freezer also.
What sort of parts are you after for your mill?
Hi all,
Thought Iād share this as it may be helpful for someoneā¦
Ok, I had a fun night last night with the following on axis0 only: -
ERROR_CONTROLLER_FAILED
ERROR_CONTROL_DEADLINE_MISSED
ERROR_OVERSPEED
Think I may have been getting some noise on the encoder lines 
I havenāt had this before, but I did change a few things recently that may have caused this to show up (increase noise).
I added 2 x 12v cooling fans to my spindle motor, this may be adding to the noise, although still happens when switched off.
Increased tension on the Gib strips to increase accuracy.
No.2 is where I believe the issue is coming from indirectly, where the motor is under slightly more load, therefore increasing the magnitude of the noise of the PWM signals and now interfering with the encoder.
I donāt yet have the motor cables twisted to cancel out the noise, nor do I have any shielding between the encoder cable and motor cables. In fact the encoder cable and motor cable are hugging each other for 0.5m up to the ODrive, (not ideal, but works ok with low current). The motors are only pulling around 750mA when moving and around 40 peak during acceleration from 0rpm, where the error only happened during a move.
I will be re-arranging my cabling, using cat-6 cable for the encoder and adding a twist to the motor cables, although just needed to get it reliably going again, so I did the following: -
Re-tuned both X and Y axis motors in accordance with the online the guide (due to the change in load). This reduced the frequency of the error, although did was not a direct fix.
Reduced the motor.config.current_lim on both motors to 10A. This did nothing to the error, I was just meaning to do this for a while and made sense to do it now. It may have reduced noise a little (not sure as have no access to spec anny).
Incrementally increased the velocity limit ratio under odrv0.axis0.controller.config.vel_limit_tolerance from 1.2 up to 2. I went through 1.2, 1.3, ect, and tested until it failed, where it was stable at around 1.8. So I set this to odrv0.axis0.controller.config.vel_limit_tolerance = 2
I have had no errors at all today with it running for the full day (touch wood). I still believe this to be a noise issue and will reduce this value again once I put some better noise control measures in place, especially when I attach the brushless spindle motor .
I hope this helps someone.
Happy ODriving,
Neil.
Edited: P.S. I have a 24v v3.6 board runing v0.4.11
Grab a couple of these ferrite rings https://odriverobotics.com/shop/n97xgxel6y0ufvunsxq70kih4p19nx
They make a huge difference.
Thank you @Wetmelon I will order a few of these today.
I may only be able to achieve 1 turn due to having 8AWG cable, but 1 turn is better than none .
Or that oneā¦
Either way I should have done this at the start. It will become more relevant when the spindle motor is active.
Just thought youād like to see my latest creation, purely machined out using my ODrive CNC machine with only manual Z-Axis movement every now and thenā¦ (Iām slowly making myself redundant )
Iāll be uploading a full video of the machine milling out all the parts at some point, hopefully in the next few weeks. The Z-Axis and spindle are coming along nicely too.
Hope you enjoy.
Happy ODriving,
Neil.
Hi Neil, hope youāve had a Merry and safe Christmas for all your family, and thanks for the nice little creative video for us all to enjoy.
Glad to see the spindle and Z axis is coming along.
So Neil, keep on staying safe and have a Happy New Year 
Regards Jerry 
Hi Jerry, we have had a great Christmas thank you, albeit a quiet one, but sometimes thatās nice too. Hope you and your family have had a good and safe Christmas too.
Happy New Year 
.
Kind regards,
Neil.
Awesome stuff! Merry Christmas
If you donāt know the scene: old school. You wanna see the movieā¦
Cheers Quintin, Merry Christmas.
Maybe this toy can re-enact the scene , although itās on its way down to my nephew as we type .
Hi all,
Hope you are all well, just thought Iād give an update.
Iām still doing things in the background, although have been very busy with my day job, will be changing jobs later this month and moving house (huge task when you have 2 littlenās). Still on track, the next house has a garageā¦ so the milling machine will move to there, this is good news as I can run it at max speed without worrying about swarf on the carpet, doh!.
So as the machine is packed up Iām getting into the video editing side again and planning the MGF build, where I now have a towbar fitted to my car and a twin axel trailer to transport the MGF.
What is next? Well I still have to finish off the Z-Axis and spindle, although this should be a lot easier in a garage, then itās directly on to the MGF build.
I want to do a lot more with the ODriveās in future and am now seriously looking to use them in the MGF. I may even turn up at the Birmingham NEC with it late in the year, that is my altimate short term goal anyway (charred or charging), watch this space.
Happy ODriving,
Neil.
Hi Neil, I wondered where you where, and hoped all was well in your part of the world, I guess Job, and moving would explain your absence.
Yes everyone need a shed/garage mostly for sanity sake, or at least that has been my experience.
Here is something that may interest you for MGFās future, that is you didnāt know already.
https://fullycharged.show/ let Robert know and Iām sure the show will have interest
Anyways just glad to hear you are still moving forward.
Regards Jerry.
Thank you Jerry, all is well here.
Looking forward to the garage.
I was a Patron of Robert for a good while and have mentioned it on a few occasions although think the team are really busy and I canāt get the MGF up and running quickly due to the day job 
.
Hopefully things will move quicker this year.
Kind regards,
Neil.
Very inspiring project Neil, it answers lots of questions to me which I consider in my cnc build, and sure interested to see your experience with BLDC spindle as I plan the same just with little bit more powerful 6384 120KV BLDC. One question, is 5065 powerfull enough for axes? Will it drive 2x bigger cnc?
For your car, might be better to look out at Vesc project? First of all it is more suitable for such aplications, and second there are several high power projects available to the public, you may order your PCB and build your self one which will cost you less then buying oneā¦
