It's in the "Alibre Atom3D Exercise Manual" dated 2018. Problem is on page 40 to 42. I've tried several things but, if I can't get it to work, if I have to I'll just draw the circle/hole in the correct spot. Thanks Ray

I thought if I use Alibre I didn't need a slicer such as SuperSlicer. Mind you I don't know the total functionality of a slicer is. I guess I need to learn more yet, ah nuts. I watched a video on upgrading the bed on the Ender 3 V2 to a much larger bed but, I can't remember what the size was. I...

It took me awhile but I found a forum thread about how to do it in Alibre. Slice it in the planes and save the parts like A, B , C and so on. So Ender-3 V2 and Alibre to start with, thanks guys.

I've been doing some research and I've pretty much settled on buying a Ender-3 V2 3D Printer and use Alibre Atom 3D. Since this will be my first 3D printer and 3D software I don't want to spend too much to learn 3D design and printing. I know I can get upgrades for the printer to extend it's...

mrehmus, abby, and creast, thank you for your comments. It's been several years since I looked into investment casting, things sure have changed. Last time I went to one of our local commercial casters here to get a quote on getting some work done and they advised me to look into doing my own...

I saw on line a guy in europe that had made his own lost wax molds to make small glow engines for line controlled fighting planes. In that competition they try to cut the ribbon off their opponents tail, needless to say sometimes they take more off and destroy the plane and engine. But he has...

2 stroke air cooled engine oil Not water cooled engine oil i.e. 2 stroke marine oil. As for the ratio it depends on the engine size and type of oil. Generally the smaller the engine size the greater the oil ratio. Oil ratios can go from 16:1 to as high as 100:1 but once again it depends on the...

Cool

Is there something one can do with a 3D printer that is like lost wax? Ray

Dave I really don't mind your constructive comments at all. Besides it shows I'm human like everyone else LOL. But yes I do need to slow down and concentrate on what I'm doing. For years I always had someone double checking my work and I double checked theirs. It's only the last 5 years that I'm...

Ok Dave, I see what your talking about, I thought you meant the LED. My bad, I had the drawing wrong but, the bread board is correct which is why it didn't blow up. K new schematic. Oh power supply is 22 amps, I should limit the current. I need to slow down and check myself. Since I'm including...

This is the new circuit running like it was using points. YouTube link below. LS1 coil and points Cheers Ray

Your right Dave I should know this better. I just recently lost my step-father and I guess my mind isn't fully focused. Anyway, I switched the LED to the high-side so it comes on when the Hall goes to ground (magnet on) and coil fires when the LED goes out (magnet off). The LED is fine. You...

A little more about the 'smart coil' circuitry. The coil fires when the LED goes out. This is because I'm using a PNP transistor which, kind of makes things look like they are working backwards. When the magnet is near the Hall-effect the Hall goes to ground or negative potential this turns on...

Ok more on this 'smart coil' thingy. So I finally biased and connected things up properly instead of just throwing it together. I went back to the 2n4403 PNP transistor tried different biasing to get things closer to where they should be, note this circuit is not optimized, that will come later...

Yup, as I mentioned above I just threw it together but, I will need to sort this out before the coming spring. I'm going to use a decade counter that will reset the count in/after the 8th count and use an 'AND gate' with the cam & crank signal as a lock-out to keep the sequence in time, I hope...

Yes it would. On the LS engines it is a coil near plug setup so they use 8 coils. But I guess only one could be used. I'm going to use 8 coils for my car next summer with a cam & crank signal to keep the firing order correct. Sometime this winter I'll put it on my distributor test bench and see...

Your right the biasing is not correct but, I just threw it together with what I had laying around. I really didn't think anyone would be interested in it because the coil is 12v and expensive to buy compared to other coils. If there is enough interest maybe I'll further research the use of this...

The only problem with them is they are expensive. For Pro cars MSD wants $1,000 USD for a set of 8, I can get 8 used ones for $75 at the wreckers. Mind you I can get the Ford coils for $10 each new. Or from Rock-Auto new from $18 CAD plus shipping. I've seen a lot of people in the old days, not...

Ok so here is my first video showing how easy it is to get a LS1 or 2 smart coil to fire with a Hall-effect. I forgot too mention that the coil draws a quick 6-7 amps when firing and is why I changed the 2n4403 PNP to a MOSFET and IGBT but even these will get hot and the spark will fade, best to...
