I managed paper cutting the other week thanks to the advice on this thread. My thoughts/findings below, but inspired by @Glennbo 's numbers!
I will post the settings I used, it’s saved as ‘JW Paper 130gsm’ or similar.
I found a lot of different profiles, my comments on speed:
- 10 - did work, but needed relatively high power to cut through. I did notice small wobbles in the outline when going round tight corners. There was a profile that had this speed setting.
- 5 - on the blue sheet on the wall. Probably a sensible top speed, but still had some wobble on tight corners, perhaps backlash in the mechanism or something else.
- 1 - no wobbles at this speed and still plenty quick enough
Number of cuts…
I found two was the sweet spot. The first pass would score deeply and maybe punch through in a few places, they the second would cleanly detach it. Full power on first pass would release the paper and sometimes curl up. For Islands (in my case actually sometimes) in thin paper it might be prudent to do them in a separate job first. That said I never had any fail.
Colour of the paper…
I found that a power setting for one colour was not always enough for another. Given it’s IR I hadn’t thought visible colour would make any difference! It might have been something else, but something I noticed.
Thanks everyone for your help on this thread!
