Straight to the Public Announcement -

ARC PRO set for Digital Racing.

If you have a large track layout and you attempt to power up the ARC PRO using just one power supply, the ARC PRO will reset itself, similar to a power short.  Even if there are no cars on the track, the ARC PRO will continually reset just like a power short event.

Large Tracks MUST have BOTH power supplies plugged in before power is applied.  Use a power strip with a switch on it, plug both power supplies into the power strip and problem solved.

 

Now, How did I find this out, well, there's 6 hours of my life I'm not getting back....

I converted my Arc Pro for digital only, see forum thread here https://www.slotforum.com/forums/index.php?showtopic=169186 , I then installed power boosters from the Arc Pro base to strategic track pieces furthest away from the power base.  To test everything, I took ONE power supply, connected it up, and boom, continuous reset.  

Since I always triple check everything, couldn't understand what was going on.  Undid everything, grabbed my voltmeter, quadruple checked all my wiring, no idea what was causing it.  I then decided to only connect one end of the Arc Pro base to my track, leaving the other end unconnected, and it worked.  I then disconnected the connected end, connected the other end of the power base to the track on that side and powered up, that worked, tried to connect both ends of the Power Base to the track, reset.

Upon power up, I could hear the lane changer motors "clicking" right before the Arc Pro base would reset itself.  Hhhmmm, so I went around the track disconnecting each lane switch piece thinking there could be a short in one.  After removing enough pieces, I got a false positive, because, the Arc Pro started working, not because I removed a lane changer, just the fact I removed ENOUGH of them to where the single power supply wasn't getting overwhelmed.

After an hour of troubleshooting lane changers, then I had the idea that maybe, just maybe, the single power supply was getting overwhelmed because all the "Lane Changers" were energizing simultaneously.  So, I connected both power supplies to the ARC PRO and started to put my track back together, along with all the Power Booster track pieces, and whalaa, everything worked.

So, for anyone planning large track layouts with the ARC PRO, make sure both power supplies are connected to the Base and both go to a powerstrip so when all the lane change motors energize simultaneously, there's enough power supply to handle the surge.

Say I want 4 lanes of racing and say I happen to have an extra 1/4 straight from a turn lane changer, say C7007, which has IR sensors in it.  Could I just wire those IR sensors into the existing two on the ARC PRO base so that when a car transverses any lane an IR sensor triggers and a lap is counted?

Does the ARC PRO care which IR sensor activated or just that an IR sensor activated?

@Andy P.

I see you added a curved lane changer... you know that has to be modified to wotk in ARC PRO, right?

Ok, confused, I thought the mod to the Arc Pro power base took care of all issues, not just single lane and such?  I miss something?

Thanks everyone again for the feedback.  I went back and started to make some changes.  I merged many of the ideas back into my design.

I'm still just swapping out 1 piece of track, it's the pit lane piece (see arrow).  That piece comes out, the R1 connects up to it right after the powerbase and then the R2 connects up right before the large bank.  So, pull pit lane piece, connect up two more and I can swap between superspeedway oval (close enough) and road course.

I understand the debate about the inside lane being a racing lane versus being a dedicated off ramp for pit lane.  I went back and forth quite a bit on this, I have about 15 different variations on my planning software to attest to it.  In the end there were several factors at play, for me, for know, I'll go with it and try it out.

Yes, I like the sideswipes, it forces the racer to think about the racing lane, and the R2 crossings on the road course, there's a racing line through them hitting the apex, I wanted the racer to have to ACTIVELY think about where they are, whats coming up, and how to move around to get the fastest time.  I wanted to avoid the "stay in one lane and that's the fastest lap" layout.

So, here it is:

 

"As Andy said, the re-entry onto the oval won’t work. The re-entry must come out onto the same two-lane straight as the exit."

I guess I'm daft on this topic.  I've modified my Arc Pro to only run Digital, thus, all power is in phase.  So, I can't short out any combination, albeit, I can't run analog anymore but I never had.  Obviously I'm missing something still....ugh, any further clarification please??

 

I like your roadcourse (apart from the complete lack of lane changers and the unnecessary racing crossovers),

I have a ton of track, so for me, it's finding the best combination not so much do I have it.  When I design a track, I normally start out with just basic turns and straights, just to get all the "ends" to line up.  Then I go back over and swap out parts with chicanes, lane changers, etc.  I agree, I'll be adding a few lane changers in the road course as well.

 

And above all, thanks for the huge feedback and help on this, it is truly appreciated!!

 

Thanks for the feedback !!

 

I wanted to make swapping between oval and road course as simple as possible, and I was hoping Scalextric would make a turnout piece, aka model trains, wheras it's a mechanical manual piece, so you physically can move a lever to cause cars to go straight or turn, thus, you don't need to swap out pieces or force a racer to have to switch lanes, but i digress.  So, yes, I only swap 1 piece of track to change between the two, and that is an R1 immediately after the powerbase.  The highlighted GREEN straight is removed, the R1 put in.   

 

I see what you mean, about swapping out the lane change on the left straight, and that would work, but, I wanted to try to keep lane swapping as MINIMAL as possible and right now that is 1 piece.  Again, if Scalextric had a turnout, like model trains do......ah, there I go again....

 

I was planning on performing the Arc Pro Mod, https://www.slotforum.com/forums/index.php?showtopic=169186, thus preventing the "SHORT" condition.  I never run analog so it's no big deal.  I have plenty of Turn Lane Changers I didn't use, but with the mod, I think I can use them, which I may, not sure...still debating.

 

Looking at when the road course comes back on the super speedway, I'm missing the ability to get cars off of the inside track until almost the point you're going back onto the roadcourse.  That's a problem.  I think I'm going to need those turn lane changers.

Finished my superspeedway track.  It's deisgned to run a square oval type of track for the superspeedway, however, by replacing the straight piece next to the power base and replacing it with an R2, I can redirect racers into the center roadcourse when "more skilled" racing is deemed.  Racing is clockwise for both tracks.

 

My question tho with the Arc Pro, which I have that link somewhere, is how Arc Pro deals with single lane merging. I have two areas of concern.  I'm concerned about pit lane as I want it so the Driver has to swap lanes when trying to exit, otherwise they are just rerouted back into pit lane (I prefer my tracks to be driver intensive).  Also with the road course dumping back onto the superspeedway.  I'm going from two lanes down to 1, then that 1 lane merging back onto the superspeedway.

 

Suggestions Please!!

 

Oh,  Forgot to mention, I purchased a boat load of the bank support wedges awhile back when they could be purchased separately as accessories.  I was planning on using those to give me the bank angle, I think it maxes out at 10 degrees....

Thanks guys,   the track wasn't meant to reproduce any specific track, just a track.  I'm trying to utilize the space so it's basically a rectangle track with curved edges, of course the longer sides, 12', have a bit longer straights.

I also have a inner track for when people want to do road courses, and yes, I funnel 4 lanes down to 2 using pit lane pieces and have only one power base, this happens on one of the staights.  After the power base, I can physically remove a few pieces of track, and then connect the road course up and it remains a 2 lane road course that empties back onto the large outer track.

I already screwed up, as I had some C8296 and C8297 superelevated R2/R3 45degree turns thinking they were normal R2/R3 in my bins of track.  Ooof, and it looks like both have been discontinued.  I'm thinking the R3/R4, without the Magnets, would be a more fun overall experience and be able to "maintain" a more steady speed.
