Re: SERIOUS COMPRESSOR PROBLEM

You maybe running the compressor in reverse. Try Switching the leads.

Re: SERIOUS COMPRESSOR PROBLEM

Does the compressor keep running, or does it shutoff?

Can you post your code?

In MPLab you would use:

Code:
realy1_fwd = !rc_dig_in06;

Re: SERIOUS COMPRESSOR PROBLEM

well i use easyc pro, i got the compressor working, turns out i just had to turn the knob, but it still seems like its not sucking as much as it should be it can hardly even pick up the tube, but how do i get it to stop sucking so itwill let go of the tube, i have the side of the sleinoid valve thats going to the suction cup hooked up to a spike andi have the spike insideof digital output one, so howwould iprogram it
(IN EASYC PRO) to stop sucking?

Re: SERIOUS COMPRESSOR PROBLEM

Answer to question 1 (Why doesn't my suction cup suck very well?):

You may have the secondary regulator turned down to low, or if you used a flow control valve, it may not be in the fully open position. Set the secondary reg. to 32 psi for maximum effectives. Also, try using more than one suction cup (we did) and it might work better. Also check for leaks.

Answer to question 2 (How to stop the suction?):

Turn the spike off, just like you would with any other solenoid or motor (or the compressor for that matter), the suction should stop within several seconds.

The secondary regulator is a hardware device put in series with the solenoid in the line, before it. It has a physical knob you use to set the pressure. That should be in the Pneumatics manual.

You shouldn't have a solenoid valve hooked up to a digital I/O pin; it should be on a relay output. Then to turn on the vacuum cups you do something like

relay2_fwd=1;
relay2_rev=0;

And to torn them off you do something like

relay2_fwd = relay2_rev = 0;

I hope this helps,

Ari.
