| I've decided I want to build computer-controlled CNC machines, like 5-axis mills |

| MadScientist:
I would echo the previous post Envelope and material are two big decisions From that flow cost and complexity. 5 axis won’t be cheap , so I hope you have a reasonable budget along with all that time You will need access to a machine shop |

Drivers like this: https://www.automationdirect.com/adc/shopping/catalog/motion_control/stepper_systems/stepper_drives/dm542e Motion controller like this: https://warp9td.com/index.php/gettingstarted/what-is-a-smoothstepper An industrial computer like this but much earlier version. It's running Win 7 I believe (haven't played with it much lately: https://www.onlogic.com/ml350g-10/ A 48VDC power supply like this: https://www.automationtechnologiesinc.com/products-page/switching-power-supply/48v-20a-switching-cnc-power-supplykl-1000-48 I put all of the electronics in a PC mid-size tower case. I had to add a swing-out panel to hold the PC because the driver stuff took all of the internal space. All of the links above point to things 'like' what I used but I'm too lazy to open the case to see the actual part numbers. If you go this way, do your own research. Bottom line: Everything was off the shelf and a simple bolt-on operation. Another bottom line: Pick a mill for which kits are already available. But... It's only 3 axis and 5 axis is a whole different thing. |

Take a look at Clough42 YouTube channel: https://www.youtube.com/channel/UCeKpbMimEGgLM_0tnghfoVw/videoshttps://www.youtube.com/channel/UCeKpbMimEGgLM_0tnghfoVw/videos He automated his Grizzly mill. He uses Fusion 360 to do his design work. You can search the videos for a instance where he states what software package he uses to drive the mill. I know he mentions it several times (and also describes doing calibration for each tool) but; I don't have time to look for it. It will give you a starting point at least. I don't think you want to attempt to write you're own software package. |
