Hi, Bruce, Yes, that would reduce the maximum frequency, but at the cost of resolution.? As I am not sure how critical the resolution is to the application, I would tend to preserve the

I had a single y axis ELS system with a tachometer and a hall effect magnet for the encoder. The system worked alright to a degree but was getting skipping issues. So with a great help from Richard

Ralph, Regarding my ELS purchases… I bought the encoder pulleys from SDP in Hicksville, NY.? I do not recommend them.? They are quite expensive.? I ended up paying a total of $40 in shipping

Wouldn’t that be fixable by a larger gear on the encoder, reducing the ratio? Or would it require redoing the mount? -- Bruce Johnson "Wherever you go, there you are." B. Banzai, PhD

Hi, Richard, I ended up using an 600 PPR encoder that has identical specs to John's.? The mechanical speed is not an issue; maximum spindle speed with the gear reduction is 1250 RPM; at a 3:1 gear

Thanks John, have have a lot of Nema 23 motors on hand, I do not know the specs on any of them. If I ever get to my shop I'll start looking at mounting them. I have relatively speaking a lot of room

And while we are on the subject of 3D printing, here's a couple of useful and inexpensive projects for drying and keeping your filament dry. Food Dehydrator as filament dryer:

STEP and IGES files are pretty much universal among the CAD programs, with STEP being the preferred format, IMO.

Apologies for replying to my own post but to overcome the problem I outlined it is possible to buy an 1800 p/r encoder E6B2-CWZ6C via Aliexpress this unit is rated at 100Khz and 6000 rpm. Obviously

Hi Ralph. Playing catch up on e mails. Phew !!!! I used a 3:1 ratio,the 6 mm dia encoder spindle 10T and the driver off the spindle 30 T. 2.5 mm pitch and belts accordingly. I believe Charlie

Talking about DXF, DWG, STL, Iges, Parasolid etc etc. I use M Cam (old prog ) for drafting, does all I need but limited to the above to export files. Cheers John

John, that is indeed good news! Sharing and file transfers? I assume you are talking beyond the group's Files section. Do you intend to make this exclusive to all members, some members, or the public

Members, have we struck gold or what.? Robert Furmanak, we? have been friends for over 6 years. We lost contact as he moved from PA to FL.a few years ago. He was my mentor to allow me to move forward

Charlie, how did you get the timing belt for the encoder on the spindle? Ralph

Bear in mind that the 600 line encoder was used as I had one. Ensure you check how your top spindle speed relates to the lines, ratio and max encoder revs from its specification! Typically a 600 line

Hi Greg. Thanks for the post. In this first trial I am using PLA. and see how it all works out. ABS is stronger but can also become brittle ( I think) over periods of time. Heat will not be an issue

Looks good, and sounds like a good plan. What filament are you using? Is heat resistance or strength a major consideration? I have a MicroMark with the BLDC motor, and am satisfied with the torque,

Just preliminary working on a 3D plastic Real Bull motor bracket. I cannot see why it would not work, this would remove the process of machining from aluminum billet. The bearing bores x 2 would be

Hi John, yes thank you! Of course I have two lathes (4x12 mini and 12x36 Craftsman) to do plus I want to do my Clausing 8520 mill. As late as I am getting into any machining I think I am going need a

Oh... sorry, I should have explained... As I am sure you all know from your own experience, when a part is spinning at a fixed RPM rate, the surface speed of the moving part is greater the farther
