not much of a difference, at anything from 100 to 600 speed setting, as someone who has worked with electronic and mechanical devices all my life i’m tearing my non existant hair out…..

Last night I even removed the stepper motors and refitted them after turning them a quarter turn in case it was a bearing on the stepper…

for 2 days now the tech support woman in china has tried to send me their software, artcut 2005, I ‘have’ to use that to prove to them its not something with my software, today it did transfer in the time allowed so she has emailed it she says, i cant see it arriving as its 38mb and i think google will reject all above 25mb

Oh I also tried changing the tension on the carriage belt, it causes a change, but does not remove the fault

Once again this machine proves to be 100% consistent, consistently wrong…

Ok i’ll go through all the points in one post 🙂

The material is riterama ? I bought a few rolls in various colours off ebay last year when i got the cutter and have bought a few since to add more colour choices etc

the blade from the start was the default 45′ blade as supplied with the machine in a pack of 5

about 8 month old i saw a wobbly line, and being a noob just thought it was a dull blade, so i played with the pressure setting and it seemed to fix it so i thought it was just one of those things.

month 9, came back, but so slight i ignored it, I was cutting comedy stickers and political bumper fodder not art pieces and no one noticed at all, but i knew it was there and it irked me…

month 10 no cutting at all, oin holiday

month 11, it was worse so cut nothing..

month 12 got some work to do went to cut it, cant send any out as its terrible…

month 13 is where we are now, and i cut as a payinghobby not a full time job so i’m maybe 70m total cut? i have had to replace my 30m roll of yellow etc, only ro;; i have had to replace, i’m not high volume here!

I have taken the blade out and put the pen carrier in and let it draw my cuts, saves on vinyl and you can still see the fault…

Fonts? I dont have to convert the fonts to points/lines etc, but if i let it cut a letter as a font i dont know if its the software converting the font to a wobbly line or a staright one, by converting to point I can ‘see’ how its interpreted each letter.

on the letters with the wobble i even deleted the letter and drew it again by hand etc so i knew exactly how the letter was formed, its elimination of anything that could be a possible cause.

I know signblazer is the lowest of the low in some places/forums but it can cut a square failry well usually! (that and I dont have 200 quid to spend on a replacement software package)

ok so now the HW side of the issue….

I have got a ”tech support” on skype from HFLaser who are ‘redsail’, they make laser cutters and CNC cutters, using the same motors etc as in their vinyl cutters, they know a thing or two about steppers, and they are built like tanks the old way with very little plastic, thats how i like my things made, i’m the guy who would choose a 40yr old landrover over a porsch anyday of the week.

the tech support female is ”level 1” , seems she is a first line filter for people who may have installed the wrong driver or cant the the cables in the right holes, but she has agreed that my lines have ”fluctuations” and is taking the photos and videos i have sent her to someone more ”shop floor”

only issue is timezones, I send her this stuff one morning and get a rpely the next, our 9am is her 5pm so we have a 1hr window each morning to try things.

I am actually impressed they are bothering to even try, its not the kind of support i have got in the past from companies some even being in the uk….

my best guess is its a PSU issue or a belt thing. the ‘wobble’ in the lines I think is from the head/sled/carriage wobbling left to right like the belt is too tight or too slack. maybe its the cold winter coming in thats making the aluminium bed length shrink and slackening the belt??

I have looked at the psu, it has voltages, are they correct? who knows theres nothing to say what they should be!
I have 31v, well 20-40 is usually right for steppers, I have -8 ? I’m presuming thats to lift the blade up, I have 10-12v, I’m thinking thats the head pressure voltage (and the one i thought was to blame) and 4.99v which will be the 5v cpu line.

usually in cheap product capacitors are often of poor quality and ‘dry out’ then dont do the job intended, this leads to the popping and taking out other parts in the psu, I have replaced the capacitors in this, fitted better quality ones, no change in fault….

All I can do is wait and see if they know what it is, otherwise i’m out of the game.

I made them a video as they(she) requested, and as you can guess when being filmed it behaved better, not perfect, just better, but i did have one sheet of paper left from the night before where it was bad thankfully..

well I posted in there fb page and a you tech support person tried to use basic translated english to help me, but nothing cam of that, so she has asked me to make a video, and email it, and she will pass that on to someon in production(?) to watch.

I was warned about quality of cheap Chinese sourced cutters, but theres no technology in these things really, its two motors and a knife up.down, very 1970’s, which is why i’m ashamed i cant get to the bottom of this!

at least as I said its built like a tank, everything is really simple and thick steel or aluminium, only plastic is the end covers, even the bottom cover is zinc plated so it wont rust. I may one day even buy one of their laser cutters and cnc setups the toughness of this has been so impressive

now only if it would cut like it used to…..

quote Chris Wool:

probably find the knife holder is seizing up not alowing the knife to move free enough.

do you mean spin? or up down?

I will get the wd40……

this is how i cut the lines/text, if i can embed this image properly, pardon me for being less than knowledgeable with some of this…

But basically i convert all my fonts in the design to lines/points as i have in the past had fonts look ok that are not when scaled etc, so if i convert them to lines i can play with then to finetune spacing / size customize them

So the letter I is just a line, with 3 90’deg turns and a start/end point, it should have no wobbles…

Thanks everyone, the replies are kind of like i would expect, but as a mad inventor I had to try!

as *all* my outdoor work will be of upto 150mm square maybe I can get a cheap chinese UV type printer in an a4 format and use precut vinyl or 200mm wide rolls

theres probably some people shaking their heads about now, but my ”work” is in a different world, i just got an order for a ”shed load” of stickers in 6 colours, and the stickers are 15mm square, and the other order is for 10x18mm…..
(something to do with RC model cars etc)

If i ever had to print something as big as a cornflakes packet that would be a ”extra large” for me lol
