Aimtrak recoil not keeping up with trigger presses
« on: December 26, 2017, 06:53:42 pm »
I purchased an Aimtrak gun with recoil installed from Ultimarc, and just finished setting it up today.  Everything works but the recoil will only work every 2-3 seconds.  So if I'm playing Time Crises, the first shot will trigger the recoil but if I shoot 5 times in a row the recoil will only work on shots 1 and 4.  Does this seem right?  I'm using a 36v 3 amp power supply which is what Ultimarc suggests using so I don't think it's a power issue.

Edit:  I may have figured it out, if i turn down the recoil force it goes fast, it's when i have it turned on the highest force that it can't keep up.

The power supply is likely cutting out and taking time to reset and power back on. So this might indicate the supply is not the specification stated.

 Im no electrical genius...  but it would seem to me,  that adding a Capacitor to store enough energy in reserves,  would be the desired solution.
Which capacitor to use,  and where to install it... is up to the true electrical wizards.   I have a good guess about it,  but Id never trust ruining something of value over a guess.

Capacitor discharge was the first method I researched when designing the recoil but it doesnt add anything to the solution. The best way ended up with a power supply which is current-rated to be able to deliver full current into the recoil solenoid, limited by the resistance of the solenoid and the connecting wire, for an unlimited time. Then, limit the actual firing time to 40 milliseconds max, in order to prevent the solenoid from overheating. That gives the biggest "bang for the buck".

Interesting solution.

 I have a feeling that many power supplies Amp ratings are more based on maximum draw potentials... rather than a nearly continuous stream.

 I think you should offer the correct supply as a package deal.   Or at very least... give people a solid source link to specific model(s).

(Excuse me if you have done this already...  have not visited the site it a bit due to life being upside down,  and sadly, losing the encoder
in the move that I had purchased long ago.   :(   )

The rating of a power supply definitely should be continuous otherwise it is not a valid figure. Most examples of powered units such as laptops charging would consume a fairly even load.


We do have links to examples.

We dont sell direct owing to no liability insurance is available when selling AC powered units within the USA. We checked thoroughly!
