Recently converted my lathe to VFD and I think? am getting EMI interference on my RELS as the z axis motor judders and misses some steps.? I thought it may be the encoder cable picking up and I

My ELS starts at 0 for the X axis value and a thread is set up with a Total depth, depth of first pass and depth per pass plus a number of spring passes that don't change the depth. CNC requires

3D printed a encoder box and lid. Helps keeping the chips and coolant away from the encoder. It just sits on the top of the 7 x lathe headstock with double sided tape. Also I am currently making a

What would be nice for Xmas, with the experts on board this forum is a new RELS feature. The Arduino RELS firmware to be able to have a designated surface or face operation, using preset depths to

BTW, one of the nice things about castings and patterns is that if you screw up you can melt it down and do it again. Or if you decide you want a different motor cast another bracket. Brushed DC Servo

Bill, Thanks You've got a couple of years yet to catch up. I just went through one of those treadmill stress tests. They keep upping the speed and the incline while the 10 probes stuck all over the

I am so hopelessly outclassed! ;) When i grow up, I wanna be like you, John. Seriously! I guess I better start growing up soon, I mean, I'm 64, and would need someone else to do drawings for me to

I think because I made the Gingery lathe and a lot of other bits and pieces the practice has resulted in repeatable results. Like a musical instrument, practice, practice, practice. And I know

Lots of draft? The green sand was just the nice consistency. Rammed hard enough. Then tapping in all directions so that I could pull it straight up. It was done on the 18FEB2018 so almost two years

The acronym is FM, for "freaking magic!" It is gorgeous, isn't it? Last aluminum casting I did was pretty good looking until I started cutting it. Found out it was an aluminum sponge. My furnace and

John, how did you pull that mold so cleanly? http://www.autoartisans.com/mill/HarmonicDrive/Pulled-1.jpg Ralph wrote:

I'm working on that concept. I still think that it will be either a Raspberry Pi or a BeagleBone Black since running LinuxCNC (MachineKit) under the covers is the nicest solution to creating an ELS

The back plates were stamped and bent aluminium with some pressed in threaded inserts. They weren't overly expensive but even at about $12 with setup costs I was still holding onto over $1000 worth of

Good reference on the issues of micro-stepping. I believe that is one of the reasons why Gecko switches over to full step above the resonance point. But I've been trying to tell people for years that

I have a few of each of those. Now if I only had the time to play with them. John Sent: December-17-19 2:23 PM To: [email protected] Subject: Re: [digitalhobbyist] Step #1 Encoder The Mega

You obviously have a lot of expertise John. Is it possible you could adapt your design to the new possibilities that have emerged in the 14 years since your initial creation?? ?

I don't know what your backplates look like but talk of heatsinking made me think of aluminium. It is possible to do investment castings of aluminium using the lost PLA method. Like lost wax but you

The Mega with Ramps was the basis of the first On-Step design and it does still work and is still supported although rarely used in new builds unless there are country specific supply limitations. The

Whilst I didn't follow all of your explaination I did pick up on 28,000 rpm and had the impression that's some kind of upper limit you might aim for. So, whilst still not understanding, I'm guessing

Interesting. If you only assembled something once and done then simple bolting into the PLA itself is viable. The pull out force on the cheapest insert was low but potentially useful.? Lower than PLA
