Oh yes, the motors used are from the 3d printing world too. Neema17 is a popular size although there are larger and smaller. Ant?

I follow a forum called On-Step where similar technology is used to point telescopes at specific parts of the sky and follow the apparent motion of the stars for astrophotography. The same issues

When I converted my South Bend Heavy 10L I wanted to maintain the historical (1942) operation of the lathe. I wanted to keep the gear cover. I can post some pictures of failed attempts. Ultimately I

Hi Richard, Interesting about the servo steppers. I'm using DC Brushed Servos (or the Bergerda AC Servo) with a 3000 RPM constant torque rating of 1.6Nm and 3:1 reduction on the X axis. The Y has 4:1

Just for info here are some (poor) photos of the encoder and stepper mount on my lathe. Just remove that 32 tooth gear and replace with a pulley. Note that I mounted the stepper on the banjo and drive

I CNC'd my Seig X2 because I could! Just about all of my projects seem to be about making or enhancing tools, actually very little in the way of making anything else! The Seig is simple to CNC in my

Hi Charlie. Thanks for the post as I am sure many forum members are thinking the same as "is CNC mill conversion worth it." ? So iIf I may throw in my 10 cents worth.then here i go. My Weiss mill was

Hi Charlie, One thing I might mention. Almost from day 1 I've had a Shumatech DRO-350 and scales on the quill and X/Y axis. With a touch probe it's easy to find the center of a hole. Same with

Gears have way more "slop" than the steps on your encoder. If the gear rattles a bit, your encoder could go crazy trying to discern speed and direction. Regards, Rex wrote:

Ralph, I agree with Richard.? The bearing on a small, inexpensive encoder of the type we can source easily from China would simply not support the radial load of a gear that size.? (Personally, I

John, Many thanks for the examples, explanations and links!? It seems to me that "following the curve" and such otherwise extremely difficult tasks are the biggest benefit. -- Regards, Charlie New

Many thanks, Bruce... Sounds like the CAM component must be compatible with the CAD element... -- Regards, Charlie New Jersey, USA *MURPHY'S CONSTANT: Matter will be damaged in direct proportion to

Just saying I could disengage, who knows why. I could put a flat belt on the two gears, if you really want a timing belt. I am really looking for feedback and help since I do not know what I am doing

There is no way I would run an encoder for the ELS via a gear. I would suggest that with an encoder with a shaft you only consider a timing belt drive. Also why would you want to disengage the

Actually I will be using 1:1 I have a 32t gear to match the 32t gear on the end of my spindle: [image: IMG_20191209_153625804.jpg] I will have to come up with a shaft but gee isn't that why we have a

Note these are readily available for free, by picking up dead inkjet printers. The encoder needed is on the left-hand end of the platen and the sensor circuit is usually a simple U-shaped board

The original RELS software was based upon using an 1800 line encoder disk taken from an HP printer, therefore No Cost! That option is still available to you if you can get hold of a disk, read head,

Hi Bruce, I've been doing a similar project for the last 10 years or so. It started with adding Power Feed to the knee since the cast hand crank didn't fit very well and it was a pain to move the knee

Hi, Ralph, The existing RELS Arduino sketch is set up for 1800 pulses per spindle rotation, though that can be changed.? Have you thought about how you will affix the encoder to the spindle?? It

I am just about done with my Must Do's and will be headed to my shop for the next two or three months. I want to do ELS (#RELS) on my Craftsman?101.07403 12x36 Lathe. I also have a Mini Lathe 4x12
