hi there
your pendants look great!

it sounds like the difference between CUT and ENGRAVE.

eg. CUT = following a vector path, either on lower power/higher speed to mark a line on the...

thankyou Exlaser and Melody.

- mechanical - there does not appear to be any undue play in the mechanical system.

- Gap Optimize, thanks - we have now checked this option. it does make an...

Could it be something to do with one of the many door interlocks?
maybe one is barely making contact.
the laser will not fire if one is broken.

of course this does would not explain the...

hi everyone

just to confirm that replacing the 'suspect' L6203 IC has repaired the GCC spirit to full working order.

if anyone has such a fault with their machine ( dead X,Y,or rotary ) then i...

sorry its a 1200x900 not 9m!

good day all,

we have recently purchased a new chinese 1200x9000 120W RECI machine.
it replaces our old 900x600 60 watt which has run without major complaint for 3 years and is sold off to a new...

Ive had time today to get the probes on the main board....

"think" i have found the problem!

so the mainboard has 3no. L6203 chips fixed to big heatsinks.
in my laymans terms these are indeed...

Dave, thanks for this.
much appreciated you taking the time to make these enquiries!

spoke to grafityp and gcc mainboard is currently about 400+VAT gbp.
so maybe not quite as horrific as i had...

rodne,
had the meter on the sensors. all performing as they should.
0v when open
+5v when closed/interupted.

you got me thinking that maybe i had physically damaged the y limit sensor when the...

Hi Rodne,

have had a look at the sensors, but dont think that is the problem.
unless i somehow broke the sensor when it crashed home.

will try plugging in a sensor from elsewhere


i must...

Thanks Rodney,
have been into the diagnostic mode ( hold autofocus button on startup )

y motor diagnostic, gives readout on the servo position, so the motor is reporting its position, but no...

Hi Dave

thanks for your reply.

i'm maybe being thick but it looks like 'everything' is on the one motherboard.

im certainly not an electronics expert, or even approaching it - but the...

Dear All

i think i have managed to blow a servo driver ( Y axis ) in our GCC spirit.

i was using the rotary axis, when the Y axis started behaving erratically.
normally using rotary axis, the...

thanks all,

i think we are going to shell out the money and buy an OP Lasers pin table.
expensive but i think in the long run it will out-live many honeycombs...
and outlive our laser probably!...

Epolitodk - thanks very much for the tip - hadnt seen these guys. those tables look great if a little expensive. but then, it would last a lifetime. and you get what you pay for.


Melody, thanks...

Hello everyone.

does anyone know where i can purchase a quality vector cutting table in UK / Europe ?

they seem to be hard to find -

LITOGRAFA - do you still sell those beautiful pin...

true - as i say be careful.

spray on to the cloth rather than the machine


but it really does remove scorched marks on the aluminium bed where everything else has failed!



kind regards

see my actual post - i must have clicked 'post' too early.

cheap and available from supermarkets etc. you might have it in the house anyway


may be a...

Hello all,

its been a while since i have been on the forum - busy with two jobs and laser cutting!


My GCC spirit has started misbehaving - producing serrated cuts.
i recall reading ( i think...

Hello all

does anyone know if Rhodium plating metal will mark with CO2 laser?

i would think its unlikely unless thermark is used?

or do you need YAG, end-of-story ?

Hey dont hi-jack forum threads please.
Your beef with Litografa does not belong here!

Hi im just reading your thread and looking at the image...

Some of the other guys have suggested problem with encoders, and possibly with belt tension.

however, i have had the same problem...

Hi Nick - yes. im kinda resigned to this fact now!

I hooked up the parallel from the old PC again,...

it MUST be the pulse settings!

i dont think you can damage it by trying different values. ( at your own risk! )
just be close to the emergency stop button in case it tries to go past the X,Y...

sorry 66% , not 64% !

interesting to try,

if you make a drawing 100% size of table, send to machine - it will laser at 60% size with your current configuration?
