Cutting mdf shapes with a Laserpro Sprit GX. Help please?

[Denise Goodfellow]

I don’t think it’s possible

[John Thomson]

Laser mdf or B & Q mdf?

Are you running air assist?

Depends on thickness , 40w should cut 6mm just fine.
The secret when doing wood is to set the PPI low , like 100 or so.
All lasered wood has char , unless you using a real high power laser
Settings should be something like ppi 100 , 100% power , 2-4 speed?
We actually use LDF (low density fibreboard) when doing this , its about 2x easier to cut than Mdf

hi

what does ppi mean?

PPI= Pulses Per Inch from what I remember.

I don`t think we have that on our software, its power and speed i think

[Rodney Gold]

if you use the laserpro driver , you will find PPI
PPI kinda works by drilling holes (treppaning) next to each other , the higher the PPI , the closer the holes will be to each other. Only active when vector cutting…

For wood , you need to reduce the ppi , so that the holes DONT overlap too much (putting heat into the substrate and charring it more) and you will get a much better edge finish …
You need a TON of air assist when cutting wood , the nozzle should be emitting an "angry Hiss"
A laser is not the tool for wood stuff , a small CNC router is better.. when you got a hammer in your hands , not everything is a nail 🙂

Hello Nick,

Just as Rodney says and you should be fine, if you get stuck with anything then feel free to give me call or our tech dept for help with any LaserPro model 🙂
