I opened the board file provided in the toolerator website in KiCad and then used the print command and printed the appropriate layers to files. I then sent those files to pcbgogo. The files determined all they needed to know to produce the boards.

How does it work sending the files to a pcb maker?
You have to solder all the components yourself I assume?


For PCB-only, yes. Some also offer a PCBA service ( including Seeed ) but this costs more, obviously. In the case of Seeed you need to select PCBA as an option and supply a bill-of-materials. I have never tried this, so don't know how it works.

Hello, and sorry for the Noob question!
I just got a Emcoturn120 and I like to convert the Controller as well.
But I used EdingCNC before together with a smaller Lathe, and I've much more skill in it.
That's the reason I would like to stay at EdingCNC.
Is ist possible to use other systems as LinuxCNC?

Thanks in advance and stay healthy
George

Great tool, just got it working lately on my EMCO 5 CNC, which is running on LinuxCNC 2.8.

The HAL-component is compiled as singleton. In my case this leads to failure during the building process (undefined parameters 'names' and 'numbers'. An easy work-around is to compile it without the singleton option. This requires a small change in the hal-file using this component.

Because my EMCO 5 CNC has 6 tools in the turret and the original DC motor has been replaced by the previous owner by a NEMA17 stepper, I wrote Arduino sketch for this solution. I named it the toolerator500. The number of tools can be changed easily in the code, by just changing the TOOL_COUNT definition.

I also changed the hal-component to accommodate the changes for the toolerator500. The hal-component is compatible with both the toolerator3000 (DC-motor based) and the toolerator500 (Stepper motor based).

The files can be downloaded at GitLab .

No, this won't work as EdingCNC cannot handle the HAL-file. The sketch can be maintained, but you have to roll your own communication class. I doubt it whether it is possible.

When you retrofit the turret with a stepper, you can assign it to be a rotary axis. I have a macro for EdingCNC for this use case.

The only thing you need is:
- Arduino Micro
- Stepper driver (maybe a Polulu DRB8825 will suffice)
- Turret with stepper motor

There is no design for a custom PCB, some wiring will suffice.
