Hey all, I don't own a Pro 300 but I bought one for my friend. Does it have a shot counter so you can see how many shots you've pulled in total on the machine?

No, it doesn't

I just picked up a used Profitec 300 for a great price and happened to be the 2400W version. It will either be a backup machine for myself or for a friend starting out with espresso. Looking forward with playing around with it and comparing with my past machines. So far my impressions are that it's built very nicely and I have no issues with steam. I'm trying to dial in the brewing but I still need to re-buy a 58mm bottomless portafilter and precision baskets.

Just some questions:

1. I was looking to adjust the OPV and wondering where it might be accessed. Is it the brass screw located on the top when you open the lid?

2. Is there anyway to configure the PID behaviour? I find that it blows past the target temp after some shots, up to 7-10 degrees before cooling and settling down to the target temp.

Hi GMK, are you able to please share the file to 3d printer the handle for the water cover?

The pics look amazing!!
GMK wrote:Hi Pro 300 Users,

I would like to say thanks to everyone who has posted in this thread, your posts helped me to make the decision of purchasing the Pro 300 over some other machines. I really enjoy using the Pro 300! The quality is awesome and the fast warm up time is probably my favorite feature. I used it two weeks ago during a family vacation where we were 14 people total, and could crank out 10 cappuccinos one right after the other without it skipping a beat. If you are considering this machine alongside some others I don't think you can beat it for the price point. I'll also add to the aesthetic discussion and say I too was hesitant on the aesthetic of it compared to say a Rocket machine, but in person it looks great and It always gets compliments.

I would like to show some 3D printed extras that I have designed and printed for my Pro 300. The first is a tamper stand and the second is a handle that fits into the holes of the water tank cover. Not that the holes weren't easy to grab, but I kept some cups over them to keep dust out and the handle blocks those holes nicely and looks better than upside down cups imo. The tamper stand I also plan to re-print in black at some point in the future so that it matches everything else.

The handle ends are threaded and 3D printed nuts hold it in place.

If you have access to a 3D printer I would be glad to send you the .stl files for your personal use!

Hi everyone, I joined the 300 club getting a used one a few months ago. I had been looking for awhile and one came available. I've got it paired with a specialita. It's been a great machine so far. Really happy I went with a dual boiler. I've been making an espresso for myself in the morning and a cortado for my wife. Not having to switch or wait has been great. It's been fairly easy to pick up for my first machine, workflow is quite simple. Don't know if I'm missing preinfusion or not but I've found grinding finer and running more in the 40 second range for 1:2 ratio makes a good espresso for a light roast I was used. I know looking for machines the previous comments in this thread were helpful, hoping to add to that.

Did you find out more about this? I found a link on CliveCoffe
https://clivecoffee.zendesk.com/hc/en-u ... d-Settings
which explains how to set the PID parameters and the recomended values for some of them. But it does not explain the meaning of all of them (there are also more than the ones listed). I am particulary interested in knowing the meaning of the b-parameter.
Edit: It defines the proportionality band.

Hey Everyone, I just got a profitec pro 300. Really happy with the results so far. Wanted to gain some insight to see if anyone else's machine does this. When I turn on the machine and the steam gauge comes up to pressure (I set it around 1.4 bars,) after a couple of seconds the pressure gauge drops to 1.2 bars. Then the boiler clicks on and the pressure rises again. Then drops back to 1.2 bars. This oscillation is happening without the steam knob turned on. Just curious if this is the way the machine works. I thought the gauge should sit at whatever you set it to. Thanks all.

Pressurestats have a dead band. They turn on a bit lower than set temp, turn off at set temp, then the pressure drifts up a little bit as the rest of the heat leaves the element. 0.2-0.4 bar is pretty typical for the tighter ones.

Would that affect the way machine functions? Ie in my case it seems to cycle between the 2 pressure setting without ever settling on one. It'll hit 1.4 bars, then drift down slowly and then build up to 1.4 again. It seems to do this at least once every couple of minutes. Thanks for the help in advance.

well there isnt a lot you can do as the steam boiler is run off a pressure sensor. when it hits the low (1.2 in your case) the heating element turns on. when it hits the hi (1.4 in your case), it turns off the heating element. you can change these absolute values if you want but for a double boiler i would leave it where it is (if you had a heat exchange machine then we could move those values lower but thats for another topic :) ).

as this is only the steam boiler pressure (proxy for temp) then the only difference you will see is that you will get a high velocity of steam at the 1.4 setting than at the 1.2 setting, thus you might be able to heat your milk faster BUT it could be harder to control the texture. at 1.2 it will take a little longer (say 5-10 secs) to heat the milk but you might get better texture.

i hope this helps a little and you machine seems to be doing exactly what it should.
