ELS is great but want to make some very simple code mods

[SteveMaxPerry]

I don't have a real problem per say other than I'm not a good programmer. I see so many other uses for this system other than driving the lathe leadscrew, which is what my first ELS has been doing successfully for three years.

But now I'm adapting one to a Chinese mill-drill to drive the mill's X-axis from its spindle. This allows for some great potential for simple power-driven feeding or driving a rotary table or even creating gears via hobbing. James has expressed some interest in hobbing previously.

But for now I want to A: Remove the lockout feature that prevents mode changes and B: Prevents reversing and C: Inhibits power on-off whenever the spindle rotation is being read. Being able to have on-the-fly control over the mill table at all times is different than doing threading or turning on the lathe.

Also, instead of the default feed rate of .005", I'd much prefer to start with the minimum feed of .001".

These changes must be super easy to do for someone that knows code, that's not my specialty.

Thanks!

if you dont need to sycronise your feed to the spindle speed you may want to look at one of these motors avalable on Amazon and Ebay. I had the same thing in mind for a poower down feed for boaring o0n my Grizzly G0705 mill. I ended up using this motor
. It has full torque from zero through yh operating range. I run it with a 1 to 1 ratio with a toothed belt to the slow feed wheel. Its free turning enough to still alow hand feeding for mill work. aalso much les exxpensive than the entire ELS system. https://www.ebay.com/itm/186315950355?itmmeta=01J0NZDEA5HN3NGGPTJ8R2HZS0&hash=item2b614bc913:g:jGsAAOSwGCtioBDW&itmprp=enc%3AAQAJAAAA8PG0gYxIeSmWWv4QkFz2HEX%2FXUFBXEDEX8IIEPoW%2BDZfiPyUj%2Bl9t7kSNYWIQM%2FRC8VWUiVrRtZdorjrSBbd1NX6sp8B105nahI1sUizmYtoU7nPjUhUJ4BbMYEzwqsG26VpvLGS%2F4sggkZfR%2B%2BIBQzNy6A1mwo9pJU1HPopBRK7X1gbE7f8sTgszn%2B%2BQUKzGBAfNeD2MoEltSjIRuCNxV7NAF6hqRGIcAcUpzVmM5tjWYk%2FhauicH%2Fm1h1w2Tof%2F%2Bu5YRaCANizilS4PCsM5h7HwsRJqDRdiqsVtjjQ%2BeYKIHNQPJ5HZZst0E6CKGUOmg%3D%3D%7Ctkp%3ABFBMmuW1v4Vk

Thanks but I'm already committed to the hardware and future plans for it. I just need the changes as requested in my post. If you read my post again you'll see I do want to be able to program a fixed relationship between the spindle and stepper motor rotation. I'm already over halfway there.

The motor you have there would be ideal for driving a welding turntable though. I'll look deeper into it later.

Thats fine, I intended to do the same actuall I have a second complete ELS less th stepper motor. I didnt need to track with my spindle speed for any reason. so i went with this alternative motor and controller. Just thought I would offer my find. I wish i could help you with codes, but thats way beyond my paygrade! LOL! Im 75 years old and far from computer literate lett alone righting code. I do love the ELS on my Atlas lathe though, have had it for several years now. I had an inital issue shortly after i installed it. I had an encoder go bad and take out the first input of my launch board. but after finding a much better incoder all has been fine.
Good luck with your project!!

My current ELS has transformed my 6" 1950's Craftsman lathe into a threading monster! I'm a few years younger than yourself and have owned this lathe since 1980. Made many upgrades to it such as an entirely new cross-feed dial (think Hardinge) and trued up the misaligned compound components. In parallel to the ELS is an Arduino-controlled rotary index for the spindle and to go along with that is a brushless motor milling/grinding attachment that bolts to the tool rest on the compound. This lathe will be with me "forever" if possible.

I also have a nice cabinet style Atlas 12" lathe that's going to receive an ELS even though it has a good quick-change gearbox. I need ready access to metric threads so it's Bye-bye quick change. ELS is super-quick change! Thanks.

Good morning James, I know you're busy but I don't know anyone else that's more qualified to help me other than yourself. My requests aren't to correct a problem but to customize the software a little for a unique application. I wouldn't bother you if I could figure out the needed changes on my own. I've tried a few different changes and either the control panel buttons quit working all-together or nothing changes that I can detect. Issues #289 could use a little review too if you please. Adding the ELS hardware to my mill is opening up interesting options to manual machining. Thank you very much, SteveMaxPerry
