Alan, As long as message traffic appears to be light, I thought I would tap your electrical expertise, that is if you do not mind. I have a Ni-MH battery that...
Hi Jim, ... Well, voltage across the LED is 2.25v (I'll pick the smaller voltage because it gives the largest voltage across the resistor) That means that the...
... Thank you Alan and thank you Dave. I believe that I will be on the safe side with the higher values and then select a value which will suit me. The...
On Tuesday 02 August 2005 05:30 pm, ... Unfortunately, a simple resistor won't work. An ordinary (non-blinking) LED draws a constant current, so Ohm's law...
... Thank you Ed for the information. It seems that this topic is beyond the scope of this Group and I did not intend on getting this deep here (sorry Alan) I...
Hi Philippe, I think there's a pix in the photos. Limit switches are not really needed on a Sherline mill/lathe, although they would be nice! I've wired for...
Philippe, hi, I used limit switches on my Sherline mill for a number of months. Today, the switches are packed away. It's my practice to follow the lead of...
... I think you are confusing limit switches with Home switches. You never need to go to a limit switch, in fact, its an error if the machine gets to a limit-...
My cnc machine has developed a problem with backlash, at least I think its backlash. It does not have any problems milling holes/circles/round shapes etc. but...
Hi Devin, You should connect up a dial test indicator to you spindle and for each axis perform the following: Do an initial: g0 x.1 g0 x0 Now zero your dial...
... Hello Devin, Sounds more like a malfunction than a backlash problem. Backlash can give you some variation in size but it will not exceed the measured ...
Alan, how would I check for this? Thanks, Devin ... gibs. Maybe ... [mailto:SherlineCNC@yahoogroups.com] On ... think ... holes/circles/round ... layers and ...
Tom, Both the left and the right sides of the part have the stair step problem just on different sides of the cut. The front and back sides of the cut a fine. ...
Hi Devin, Dave nailed it, use a DTI to monitor your X (or Y) motion. See if it is affected by speed. It's a pain, but you might have to remove the stepper ...
We are pleased to announce that the new TS Engineering Quick Change toolpost set now comes with 5 toolholders. The set now includes: 3x turning holders 1...
Alan, Sorry I couldn't make it to the Tuesday night meeting you had last month. I was out tooling around the southwest on my motorcycle getting some much...
Ron, What can I say? I can do no more than call to mind that stunningly succinct response that one of our immortals would offer whenever facing a situation...
... This sounds more like you're either dropping or gaining steps somewhere along the way, probably in only one direction of motion. I think that I'd start by...
Just want to make sure. . . . I'm drawing a project with Rhino3D software (so I'll have art to illustrate my questions), and I'm not sure how to make a couple...
Hi Brian, ... I happen to have Rhino3D as well. Probably best to do a rendering and then save a JPG so everyone can see. ... Well the focus is Sherline, but...
Dave, hi, Yeah, I thought that you and Pete both use Rhino3D. ... and then save a JPG so everyone can see. < I would have screen saved then converted to JPG in...
< We all have to cut some parts without CNC once and a while. < Alan, no, without CNC? don't say that! <g This is a CNC project (sorry I didn't make that...
Guys, The polarity was backwards on the x axis so I changed it and it helped a bit but not completely. I did the DTI test and everything was perfect. It was...
HI Devin, A slow machine would just run slow. You wouldn't be able to get a high rapid speed out of it. You might check the polarity of the steps, that can...
Hello Devin, ... If you mean the step polarity was wrong then that certainly would make a difference. If you mean the direction polarity then the axis would...
