I first want to thank you for the descalling page on ECM Giotto – But one question, when you mention to plug the machine even with a completely filled boiler, isnt that dangerous, pressure would build internaly.
I am in Montreal Canada,
Many thanks again

Hi, i work in a machine shop using haas cnc milling machines, I have been wanting to have a small cnc mill at home, for hobby use but cant seem to find anything small enough and cheap enough, and after looking at your conversion of the mini mill to cnc controlled, i’m impressed, what was the total cost for the build??? Have you found a cam programe for it yet??? I use featurecam 2008, it’s a pretty simple cam programe, you can download copies of it from kickasstorrents.com for free, as cam programe’s cost a fortune. Alos what kind of feed rates will the motors provide? Hope this helps,

Do you have other parts providers? Service providers in FL?
Thanks for all the useful information on the ECM Giotto.

Hi, Just for the sake of information… saw the old 3axis controller, was looking for it for a while to refresh but couldn`t find the original, thanks for keeping it alive, found a few sources for the ucn5804b controller, Futurlec is one for the original part which allows up to 35v @ 1.25amps continuous, the other you might want to checkout the StepGenie product at the website of the same name (or plug it into a search engine). Only have to workout the rest of the electronics if one wants to increase the power .

When I first took the back and sides off my machine the first thing I noticed was and unattached ground wire and I could not even determine where it had been attached and I thought “how could a safety ground effect the pump?” I guess from the business I am in which is EMI shielding including often ESD grounding issues I should have had a better idea of the multiple meanings for “ground”.
At any rate that’s how I went off on the control board fix and whole latte love agreed that it was a control board problem but thanks to your email I took a fresh look at the machine and it all made sense. I added a nickel plated beryllium copper spring finger at the bottom of the reservoir and reconnected the ground to the tank box where I assume it was originally attached and put everything back together after cleaning and I am on my 3rd double this morning without a problem.
I wish I could do more than just say thank you. Your generosity of time and knowledge has saved me $300 plus and I am drinking espresso again.

I was reading your post on the Harbor Freight 44991 & I noticed you said it took “some tweaking” I want to know when u said that (cause I am looking to buy one) does parts on it get loose ?. The other thing I would like to know is can it mill metals like carbon steel.if not then is there a kit that I can install that will allow me to do so.

Hi, I have the same Giotto and decided to make the plumbing on it. Can I just put the water intake on the pump and what do I do with the OPV hose?

Im looking for panels for my ECM Giotto. I just purchased an older model, and i want to fix a problem with corrosion and peeling on bottom of machine. Whats the best way? buy new panels, or get it sandblasted and re-dipped or coated in chromoly? Im also trying to figure out which version of the giotto my machine is, and trying to figure out if i have the right reservoir. Someone said that the normal water tank has floats and levers and a complex system in it. My tank is simple just 2 handles at the top, so how does the machine sense when the waters low and shut it off? Can someone please help me or point me in the direction of where i can obtain parts for this machine. Im going to run through it, clean the boiler and the element, descale it and im sure that i will have to replace the gaskets and some other things, its just hard to find parts for this machine. I was also curious if this machine has a 3 way valve and can be backflushed? Below the infusion pistion i figured that was the 3 way valve but im not sure. If anyone can email me and give me a suggestion it would be greatly appreciated and im sure i could return the favor. I normally fix high end espresso machines with no issues and i own several but i dont know much about this machine.

Hi Can someone please tell me if they have a water tank/reservoir for a ECM Giotto that they would like to sell? The tank that came with my giotto when i bought it, i beleive isnt the original tank and i dont think it could sense the low water and shut off the boiler. If anyone knows a great deal about these machines and could give me a hand, id be willing to pay someone for assistance. I have valid paypal account

I came across your blog entry on the 1980 xs850 efi conversion using the megasquirt modules and some triumph throttle bodies… Did you get any further on that project and if so, can you provide any additional insights, notes or photos?
The reason I ask is because I am building an xs850 cafe right now and I’d like to consider EFI instead of the rebuilding the carbs.

I’ve just read your instructions on how to descale a Giotto machine. The information is most appreciated. However, I’m wondering if it is totally necessary to go to these lengths to complete the job? Is it not possible to do the same thing by dissolving a descale product in warm water in the water reservoir then running it through the machine and letting it sit for an hour or so in the pipes…repeat…and then thoroughly flush, using the reservoir again? (pretty much this method here: http://www.youtube.com/watch?v=SLQup1NKYb8&list=PL58EFCC3756C9B894&index=7&feature=plpp_video ). Your thoughts would be appreciated.
Also, an tips on how to properly lubricate the Giotto? – I’d like to know how to do everything that would be done if I was paying $300+ for a “service” on this machine! Cheers.

always i used to read smaller articles or reviews that also clear their motive,
and that is also happening with this paragraph which I am reading at this time.

This design is steller! You certainly know how to keep a reader
amused. Between your wit and your videos, I was almost moved to start my own blog (well,
almost…HaHa!) Wonderful job. I really enjoyed what you had to say, and
more than that, how you presented it. Too cool!

May I simply say what a relief to uncover a person that really
knows what they are discussing on the web.
You definitely understand how to bring an issue to light and make it important.
A lot more people have to look at this and understand this
side of your story. I was surprised that
you aren’t more popular since you most certainly have the gift.
