Thank You - Very Much - for this YT Video series, your website and your insight. I have done a very similar thing with a DynaMyte 3000 Benchtop Lathe with rotating tool turret - but with Gecko driver, and Mach3

I enjoyed every part, please keep up the good work ! I've had limited experience with CNCs and hopefully I can save enough money to get one!

[@uptimefab7412]

Thank you for the compliments, much appreciated! Expensive hobby indeed, but very rewarding.

amazing project!
tip: using cup saws in reverse leaves a much better finish in plastic. Just high speed and a steady hand and the hole will be perfect, no burrs or sharp edges.
i use this for cutting holes in those Blue plastic barrels and big ABS storage boxes.
keep it up!

Thank you!

Very interesting... why not go for a small GRBL CNC controller though? This huge box seems a bit overkill.

[@uptimefab7412]

Thanks for the feedback, a GRBL would probably work just fine. I prefer a standalone controller, since I don't want to have it connected to a laptop during use. I like that it has its own screen and keys which are better protected against dust than a laptop. It is all personal preference though, (at least for a hobby machine) if you like the GRBL approach better, that should also work fine for a simple router.

Pineline cleaner is very good for cleaning powder coated Emco. I use it on my emcos and it leaves it flat as intended.

[@uptimefab7412]

Thanks, looks like a good solution. Unfortunately not available where I live, but I am sure there is something available comparable to the Pineline brand.

Although you may not be able to find the safety door part, you can always make one by heating and bending a sheet of polycarbonate. You can always wet sand the pant to clean it up and use clear coat.

[@uptimefab7412]

Thanks for the tips! I hope I will never have to bend a new door, but that would would also be a nice skill to learn.

Do you happen to know or have the wiring for using the winnc from the pc to the machine?

[@uptimefab7412]

Hi, I did not receive the Emco WinNC software with the machine when I bought it, so unfortunately I have no experience with the program nor the wiring.

@UptimeFab one question - did you find the SZGH PLC manual is correct on their M-codes and descriptions? Working with a SZGH CNC1000 currently, and it is a bit of a mess...

[@uptimefab7412]

Hi, I have not gone though the PLC M-codes used in the controller beyond what was discussed in the video, so I am not sure if the codes in the PLC manual actually correspond to the ones used in the controller. I probably can't be of much help here. If you would like me to check something specific though, I can try to help.
