A Better SEIG 7x14 Mini Lathe Spindle Upgrade | BLDC + ODrive

[@nickldominator]

3:08 VESC can most definitely run with encoders, even the exact one used here. Pretty sure Benjamin Vedder himself has videos dating back to 2015 or earlier demonstrating it. VESCs are rarely driven in 'open-loop' mode. Most of the motors you'd use often come with at least hall-effect encoders that it can take advantage of. VESC has recently introduced HFI, which adds sensorless position tracking at zero speed. It is pretty incredible to see and it rivals dedicated hardware encoders. You should take a look. Nice video on the upgrade :)

Nice video. I encourage you to make more. You have a good presentation style.

[@markosfraser3030]

Thanks Brian! I already have a lot more video ideas, I'm just trying to find the time to film them all 🥲

Well done Mark !

At 2:30, there are several other owners of 7x mini lathes that are using 750W, 1000W, and 1500W brushless servo motors as well as 3HP-3PH motors on these lathes... A different presenter -- Artisan Makes -- was using 3HP until he recently upgraded his entire machine. "The Custom Crafter" in Florida is making 2HP brushless bolt-on kits for these and other underpowered machines as well. ... AnyHow, thanks for making this video and presenting your idea(s). I would like to see it run with 1500 Watts of power available and compare the performance to the previously mentioned and unmentioned presenters projects here on KZbin.... If you want to know the other presenters just contact me.

At 6:35, what is the longest, continuous powered on, active machining project you have made? How is the thermal performance of the motor/power supply in extended operation? Thanks.

There's a guy who programmed in Arduino in order to make thread cutting super easy with the oDrive you can basically do the same thing but a lot better and easier.

[@classekaka]

That's neat! How will the motor stand up to wear? I guess it's not a professional shop but still it will pull more hours than in an RC toy.

Its nice to see young people whos not in mortal danger while handling something more dangerous than wooden spoon :D

Das ist ja garnichts ich pell mit meiner 3-4mm in stahl runter. Und hab nen billigen nähmaschinenmotor aus China eingebaut. Offenbar ist die Drehzahl bei dem Teil ziemlich gering. 12er Gewinde kann ich auch problemlos schneiden.

What version of SW are those cad files? It will be nice if you upload some drawings in pdf... not eweryone have SW...

[@markosfraser3030]

Hi, my modified CAD files are Solidworks 2022. I can try to create .step files if there is sufficient request for them

[@bmalovic]

@@markosfraser3030 Thanks for info. I think more like clasic, paper drawings in pdf format. Something like full assembly or few subassemblies, will be enough for someone who is interested, but use anodher CAD, or do not use it at all, or just want to take a quick look and maybe grab some idea for other project...

@@markosfraser3030 .step files would be nice! I don't use Solidworks. Great Project!

All these vids on youtube about how to improve the chinese mini-lathe. Best way is to throw it away and just buy something better and worthy of the name Lathe.

[@johnrussell6620]

That maybe the best way, but there is knowledge to be learned either in the upgrading, or the failure to perform. An informed decision either way. Not everyone can afford a 22" American Pacemaker, or a 14" Clausing, or even just a 9" Grizzley as a first machine.

Makos, I would like to contact you about a project that I am working on. May I have your email. Thank you Osny Fabricio
