Hi,
does anyone have lasercutting files for the RCP control horns. Maybe also for the motormount (for 6mm foam)?
Cut out from plywood...

Thanks

Hi ... my system for producing Laser files :

From a plan or a drawing - I use a simple scanner .... my Canon or Epson 3in1 printers do a good job ... to scan the item needed. Then using Paint or any graphic editing program - I remove the unnecessary lines / bits so left with the item required. Save as JPG 

Another way is to use Paint to draw what you need ... 

For repairs and replacement of broken parts .......... I place broken part - even a fuselage on the scanner .... scan and then using Paint create the new part as a JPG.

My Laser cutter program allows import of JPG ... I then use the vector drawing tools in the Laser program to create the outline required by overdrawing on top of the JPG ... then unclick the JPG leaving the vector displayed.
Save as Laser file.

I then have a Laser file saved that I can cut as many items as needed.

I find creating these files super easy as they are in 2D .... unlike trying to create 3D for 3D priniting !!

thanks.

you could also save the page of the tiled plans with the control horns on it as JPG. So no scanner needed.

Reason I use scanner is to make sure I get the JPG in the size as original .... some plan saves to JPG alter the size or ratio if not careful.

Laser files also are proprietary to the program used. I use Moshidraw ..... which files are not suited to other programs.

ok, altering the scaling could be a problem.

Did you manage to create your files ??

no. don't have the cutter yet. just trying to get data files and knowledge in advance.

OK ... any ideas on what cutter you'll get ?

I just have a chinese K40 machine .. many said to stay away from them - but mines been absolute gold. Only niggle is the work area size. I wish I had bigger - but that's because I want to cut whole fuselages / spars etc. so need about 1500mm area ... 

But for bulkheads / ribs / fittings - the K40 proves brilliant.

When you get one ... remember : 
Don't go for a single pass full cut unless material is thin enough ... It's better to make multiple passes at lower setting to avoid burning / charring.
Second - make sure you have Air Blow system - this is good at preventing actual flames starting by cooling the cut material .... clears any smoke at the cut. You only need a relatively low volume air pump ... I use a laboratory air pump similar to an Airbrush unit.

For water cooling - I have a washing up bowl and I top up with about 5 - 8ltrs of cold water before start. The water is pumped by a Fish Tank pump - all it needs is a steady flow that returns back to the bowl. I can cut for reasonable period with that before water gets warm and needs to cool. I have a kitchen dual digital temp indicator ... about a fiver on eBay ... with settable alarm. I have it set at 50C. I rarely get close to that in fact. And if it does ... just add more cold water to the bowl !
There really is no need to be fancy with this ....

thanks for the tips. but no idea yet, cause i am far away of getting one. however a friend has one, but don't ask me details about it.

That's good ... he / she will hopefully help you in choosing / setup. I had no-one to help me with mine. I watched loads of Youtube videos and experimented. 

Same with my 3D printer .. I was alone with it ... 

Once things settle down - I hope to get a larger Laser machine ..... but its not cheap !! I also want a 3D Scanner !!

I drew up 3D files of RCP and FT control horns a while ago. I can convert them both to dxf real quick and post them if that would be useful

Just a note : dxf files are fine if you use software suited to it ... 

I use Moshidraw which has dxf capability - you choose the version because Moshi is written specific to each format so I have three Start Icons on Desktop. But same as many others I have communicated with - not only Moshidraw, but some others often crap out on dxf. I always now use JPG and vector myself avoiding this.

TBH - I avoid all dxf plans as well and prefer PDF format.

In 3D ... stl would be much better .. again for same reason.

My personal opinion.
