Today’s SwiftCut Issue

[Hood]

Where the parallel port starts to fall down is when you are using servos rather than steppers due to the pulse requirement of servos. As an example my Plasma has approx 1700pulses per mm and a velocity of 20,000mm/min so that means I need a pulse rate of approx 567KHz which is more than 10x the reliable pulse rate (45KHz) that the parallel port can output. Yes you can do electronic gearing within the servo drive to reduce the requirements but that may or may not be ideal.
Another thing about the parallel port is it is 5v (more often 3.3v or so) and that can be problematic for noise, personally I much prefer to have everything , I/O wise, at 24v

hi hood i agree with all your points raised,we dont use servos that would be a completly different setup and increase the cost,and if you use a cheap branded parallel breakout board noise issue's can exist thats why we build our own parallel port boards in uk at our manufacturing site with our own assembled dedicated pc's

different setup and increase the cost

Not to mention the fault finding, god forbid something goes wrong . Since I have had a few issues with mine (Gecko 320 drives) I now realise the complexity of servos. I will still admit that I don't regret getting servos over steppers, it is something you have to learn about, it is just a shame that I have to deal with Americans, that at best will answer one question at a time, regardless of how many have been asked, and hopefully answer what you have asked in a way that you/ the user can understand. Very frustrating and not to mention you have to be nice about it or you won't get an answer. They are not all the same, but I can understand why they are not the most popular around the world.
I feel so much better now after that rant, you all have a wonderfull day

AC servos from most companies can be connected to a laptop/desktop with their software and can be set up and monitored/tuned etc. Makes things a lot easier than with the likes of Geckos.

That's crap Brad! Did you buy it on credit card? There should be a way to get your money back if you did, although Swiftcut if they gave a toss should be all over this as its pi$$ poor publicity! Hope you can get it sorted.

I don’t even want it sorted now just want to get rid

That's some carry on you've had with it, you must be sick of people like me commenting about the xtreme table. Today I've done some signs in 2mm, brackets in 3, 5 and 6mm and no issues, holes in the 6mm are spot on.

 

[Hood]

Not good to hear your troubles are continuing, I was hoping after they were there the last time that you had it fixed.

When I said get it sorted I did mean getting your money back, I'd be pig sick of it too!

"Ideal for small artists workshops to colleges right through to the manufacturing industry, the Swifty is the low-cost machine with big potential"

Taken directly from their website.......... hobby my ****..

I had my Pro table serviced by Welly Welding recently. Changed all the bearings etc and gave it a damn good cleanup, and tweaked some of the settings. It was like night and day, have done a fair bit of cutting , with great results since.
It appears you need to keep the rails etc extremely clean to help it to run properly. Bought some tarps to make sure its covered when not using it too. I still don't think I would recommend them though.

Well mine is just about to cut it's next big project, two pontoons for a house boat, in 6mm alli (6 only 1830mm by 6100mm sheets, about 1 ton of plate) . Total cut time for the dxf's is 18hrs, I believe it will be three days to cut, remove off the table, and reload new plate. I will expect 0, no, aboslutely nothing to go wrong. Anything less will be unacceptable. If we have **** happening then there is no point having these machines. It is then easier to get it done some where else and let them deal with the ****

Exactly Henry

Paying for a a day of totally useless service... No thanks
You're by no means the only one who hates swift cut, I saw someone complaining about theirs on Fb group this morning. Similar sort of thing - their table is an expensive ornament, totally useless.

Great hobby - spend a load of money for endless hours of frustration!

 

[Brad93]

What i am going to do is list out all the issues and send them a properly written out email today.
Once it’s gone I can think about something else to take it’s place but to be honest I don’t think it will be an extreme as I want to be able to cut 20mm really. It’s a pain only being able to do 15.

Why is the Extreme limited to 15? Is it that it can't carry the weight?

Safe to say you are less than happy with it then Brad

I noticed they have a lot of overseas customers on their FB site. I guess if the 'murcans have the same sort of problem with their machines as Brad ,then they would be suing for $$millions

Looking at the xtreme table, I'm not over smitten with the build structure, bearings running along section for linear rails is one thing. But the feedback regarding support and hassle free use is a big, big selling point!
