Hey everyone, Just wondering if anyone has a broken CW4000 chiller unit that still has a working temp control unit? Mine has burnt out and HPC dont have the replacement part unfortunately. I could get one shipped from china but would rather get a donor part locally. (make do and mend) If you have on...

Just thought id post some pic showing what happens when you cut styrene.

Results -
edge quality - poor.
fumes - probably deadly.

Conclusion -
dont waste your time... it'll kill your machine... and you... the spiders web does look cool tho

now onto ABS......

Cheers man, much appreciated.....

Got any recommendations of a safe acrylic type material to cut thats between 1- 2mm thick that doesn't thicken at the edges when cut?

Any thoughts?

Cheers man,

i'll do that next week when im back in the workshop.

Hi there, Does anyone know if there is a way to reset the datum position? At present the laser head sits about 12mm down from the top of the 400x680 bed. I've looked at the runners position and it could move up about 6mm. Its a problem because when i cut a full 400 deep sheet the laser hits/fires at...

Hi, Id just like to second the recommendation for "DraftSight". Ive used many versions of Cad over the years when i worked in architecture (with AutoCAD being the main program) but when i tried "DraftSight" i found its virtually identical to AutoCAD and its fully compatible with ...

Does anyone else find that when you delete a large file that the machine hangs and says something in chinese? (LS6840) I work with large files all the time (140mb) and have tried deleting thru the software and on the panel and get the same result. Just wondered if anyone else had the same problem an...
