This is on my Craftsman?101.07403 12x36 Lathe. I installed a Consew 3/4 hp Brushless DC Servo Motor (

Hi Charlie, The ELS was developed on the E-Leadscrew group as a collaborative effort and is 100% open source. In fact it started out with a surface mount processor and single axis control with built

Just to add my two cents worth... I think we are comparing two different systems here. RELS was designed to make it fairly easy for a hobbyist to construct, modify, and upgrade a system themselves

I cannot remember it was a long time ago as you say in the days of the parallel port. First the RELS does not use 7 segment LEDs and secondly both your system and the ELS need button presses to get

Since the ELS came with a built in programmer that just required free software and a parallel port connection I'm not sure why you'd have a PICkit. In the very near future my ELS will use the

We are not "re-programming" with new parameters we are loading the initial software for that particular machine. Once it is done it is done, and it costs nothing in software or materials. By the way

I still think that using a spreadsheet and then reprogramming the the processor with new parameters is so clumsy. That's why my ELS was designed with a screen and 35 buttons instead of a few buttons

Duh, thanks Richard, of course Duh, my mind is not working well! Ralph

It really is not difficult! If you have an imperial screw say 16tpi enter the pitch as 1.5875mm,10tpi 2.54mm as the pitch is 0.1in A PhD is not needed Richard wrote:

re: "ease of using the new design spreadsheets" There might be ease for those that know what the hell they are doing but for others like myself there is mostly confusion. Especially for converting to

Richard. Many thanks for your inputs to this forum. invaluable. Although I already have a RELS ( was # ELS) up an running,? I can immediately see the benefits of improvements to the electrical design

If you are not putting a stepper on the X axis then a left, neutral, right Joystick is adequate plus you do not need the forward and back limit buttons with led's. Richard

I have two steppers on my Gingery lathe. The cross slide is an old surplus size 23 with very low torque so it can't move very fast. The Z axis has 280 oz-in. Both run on 48V supply and external

I have a joystick to use on my wood lathe but want something more compact to attach to the front of my mini lathe, which will also be single-axis. How necessary will the up and down functions be?

John D, uses AC Servos. Ralph

Hi, Chuck, I just got mine working, and I am using steppers on a 7 x 14 Real Bull. -- Regards, Charlie New Jersey, USA *LAW OF ANNOYANCE: When working on a project, if you put away a tool that

I have put "RELS Parts info.pdf" in the RELS files folder. Richard

Only Steppers have been used to my knowledge. I would consider the expense of Servos overkill. Parts info in a separate post Richard

For those that have built a working ELS/RELS for the 7x mini lathe, are you using steppers for the lead screw or servos? If servos please reply with specs and source. Any progress on a parts list?

Thanks Charlie, that is what I thought but did not see the arrow to expand files. I seldom use a spreadsheet. I looked again and now see them. Ralph
