I'm wondering what hardware software combination to use. the original ELS project seems a bit long in the tooth. There are 3 or 4 on github and a Russian lead screw design.The options are almost endless. What exactly are you looking to do?
I’ll be interested to see how the Launchpad works for you. I used an Arduino Mega and pretty much the same parts you have, and have it working quite well but keep thinking up “one more” improvement. I suppose I should start participating in this thread and put up what I’ve done.
found his site - nothing re ELS there! Searched Youtube under his name - couldn't find it. Are U referring to the expensive but slick Rocketronics.de ELS4?There's a nice ELS from Germany that they call an Electronic Lead Screw - Stefan Gotteseinter did a review of it on his youtube channel. They will have a complete English manual available early this year. It leaves manual operation untouched and is DIY for the home machinist.

You found me. I don't have any backlash compensation because it's not CNC, just a programmable "gearbox". The number of pitch selections is arbitrary. I've implemented every pitch that I could find in online pictures of lathes, and every tap available from McMaster-Carr. I stopped short of having an arbitrary programmable option, but it would be possible. I did limit it to 4tpi just because I have a small lathe. That's getting to be some serious depth of cut, and I have already noticed some "hiccups" cutting an 8tpi Acme thread in 1144. I'm waiting for more timing pulleys and belts so that I can gear it down from the current 4:1 ratio between the stepper and the screw. I'm planning to test it at 5-, 6- and 8-to-1.Am new to this forum, found this page & joined.. Am trying to find Jon Bryan, & more details other than the youtube clips re his amazing touchscreen ELS,
Can anyone assist please? (I am very keen to load the f/w into a Arduino Mega & test it, but need much more detail first, like backlash compensation, electronic gearbox steps, range, etc).
Yes, a bit of a learning curve here but not sure it's more than doing an ELS.Thanks Dabbler Admin., converting EU to Oz $ plus freight, might as well use Mach3! But yes its slick as, best bit is X axis motorised.
ELS4 Pro even slicker / dearer, when released.
Jon Bryan's also very nice but no X axis drive.
I am hoping to rotate spindle slowly as well for cutting long curves, so an electronic indexer, married into Z feed, all as a standalone, for those oldies who cant use mach3 or PC's, with stored settings,memory. Probably too hard..
For sure there are challenges with homebrewing any of these systems and the Rocketronics stuff looks like it will be good and it should be available any day now.The issue for me isn't just learning Mach3. there's the entire toolchain to learn. I programmed at all levels for 40 years, and -for me- those days are over. So I want a nice, pre-programmed solution that will up my game without retooling my brain for Fusion360, mach 3, dealing with feeds/speeds and other minor annoyances of CNC. The ELS feels more like what I do manually, but reducing the operator-error possibilities.
I am following the various ELS threads on youtube as well as here. It may be I can home-brew my own, but right now I'm leaning toward Rocketronics ELS in their largest size (My target lathe is 15" LrBlond).
Well, the Clough42 "product" will only be a small board that combines several functions that several separate off-the-shelf products already perform. The CPU, display board, servo, driver, encoder, and power supplies are also off-the-shelf products. I have it running now as a cobbled-together mess, just to prove it runs. The idea is to get his board when it's done, but all that will do is eliminate a couple of the individual boards; it doesn't really do anything new....Neither product is actually available for purchase right now so there's time to do more research before laying down your hard earned dollars/euros....
