Interface PCB for the ELS project

Hello Phil, good evening.

Components arrived safely in yesterday’s Post.
Thank you Phil.

Best regards

Good News!

Thanks for letting me know.

Best Regards,

Phil

PCB arrived safely yesterday, now to source the components - most are somewhere in the parts bin!

Thanks for the kind offer of the PCB, Doug. Much appreciated.

Anthony

Hi Phil, component kit arrived safely,

many thanks

Gray

Great, good luck putting it together, any problems with missing parts etc. let me know.

While I chickened out from going ahead with the electronic leadscrew project, I have been using a stepper motor drive on the leadscrew for providing the feed on my lathe for a number of years. This is an excellent half way house for those like me who may have baulked at the complexity of going the whole hog.

With a relatively simple set up you can have variable feed rate without any change gears and I have also included a feature that has proved to be invaluable. This feature is an automatic stop which stops the leadscrew instantly when a microswitch is activated by a variable position control rod fixed to the carriage. This makes things like boring a blind hole a doddle. The microswitch is simply connected to the inhibit input on the stepper driver.

Clearly this is not as good as the ability to screwcut but has proved to be extremely useful in practice.

ps. Glad to hear the pcb arrived safely Anthony.

Hi all,

I've set up a new thread Electronic Lead Screw Project for the builds and for any help/ advice needed on the way.

Hi,

I still have a few people who asked for a PCB and are on the list for the last batch but haven't responded to the PM I've sent, maybe because they didn't tick the box to receive notifications of PMs?

If you've requested a PCB and I said you were on the list for the third batch but haven't heard from me then please check your inbox.

Cheers,

Phil

Hi Phil

Can you confirm the order of the screw terminals on the PCB please? I imagine they are the same as Clough42's but I'd like to make sure, I've blown up too much kit this past year getting power connections wrong!

Cheers, Roy

Roy,

Here you go

Hi Phil

Thanks for confirming the pinout, I see the markings on the board now but I wanted to be sure. Good news that it's all working on the bench. Now for the bigger job of engineering the installation. I wonder if anyone has finished their ELS yet and how they got on?

Cheers, Roy

HI Phil , have I totally missed the boat or is there still availability of PCB and components ?

Regards

Jim

Hi Jim,

I think I have some PCBs left but not sure I have all the components, I'll have a look and let you know.

Phil
