Jigsaws can be made at rLab either by using the [[Tools/scrollsaw|scroll saw]] or the [[Tools/laser|laser cutter]]
== Scrollsaw cut Jigsaws ==
Line 10:
I've now got a couple of workable options for jigsaws made with the laser cutter. They are in no way 'hassle-free' but do result in usable jigsaws.
* The output from https://cdn.rawgit.com/Draradech/35d36347312ca6d0887aa7d55f366e30/raw/b04cf9cd63a59571910cb226226ce2b3ed46af46/jigsaw.html works great, as long as you remember to ungroup it before converting to DXF. Each vertical and horizontal line is cut as one.
* Choice of substrate is vital, some woods and MDF will create a very sooty jigsaw that is almost impossible to clean up. If the material isn't strong enough the lugs just snap off when against the grain.
* If you are etching as well as cutting, then the pieces will have to be at least 30mm in size. I tried 15mm pieces and you can't see the image due to the noise of the piece cutting.
* You will need to use 'dot' mode on the horizontal and vertical piece cuts or the jigsaw will collapse as it cuts. The degree of 'tab' needed depends on the media, too much and the tabs will get ripped off when you separate, to little and the pieces drop down and get singed by the laser.
* You shouldn't be tempted to cut your pieces on a thick bit of 'waste' board to stop them falling apart, it will be messy, and more importantly a HUGE fire risk.
My recommendations:
* Use a more laser friendly media to reduce ash/soot
* Consider using the paper tape to make clean up easier
* If you are combining laser etching for the 'image' with cutting for the pieces then use larger piece sizes 30mm+
* I suspect that a printed image, laminated onto either 1.5mm ply or 1.3mm mount board will create the best jigsaws with the minimum of dirt/mess/hassle
=== Substrates ===
* Quality mount board (cardboard) is a cheap option that has minimal ash creation, mine was from Hobbycraft
