Swifty Kerf Configuration

[Brad93]

does anyone know how to adjust the kerf allowance/correction in the swiftcam software?

i'm cutting a part that should measure 30.5mm high. it was coming out at 31.4mm so i tried adjusting the offsets but can't make heads or tails.

I had to make this parameter set for cutting 20mm steel which the swifty isn't set up for. It can be done and quite nicely with an edge start so i copied all the parameters for 15mm and then just slowed the feed speed as per hypertherm manual.

I wanted the part a tad smaller so i made the offsets 1.3 and the part came out at 26mm!

what am i doing wrong? never had to adjust the kerf before it's always cut +/- 0.5mm

Does the toolpath screen show the toolpath and the cut? If so, does changing the offset show up here? set it to something like 5mm to exagerate it maybe set the internal and external offset to different values and create a toolpath with internal and external features to make sure it is the correct setting.

How do you know its a kerf error? Are internal features undersize? or are you just using it as a work around? If its just a work around to get the external profiles the correct size you could try scaling part to 97% instead.

Sorry to state the obvious, there has to be a way to change the kerf width. In 'sheetcam' it is in the 'tool' section which has the Hypertherm settings saved. Do you not have saved section of the material type, thickness and cutting current to be used for your Hypertherm plasma cutter. These setting are also in the Hypertherm manual.

They use Libellula not hypertherm software.

Basically the two screens i've posted are all i can find.

nothing with kerf width anywhere

Libellula software sucks , at list the one used by swiftcut which is the cheapest cam on earth I think , still I don't understand how the hell to set up kerf and other parameters .

i played with the external offset all flipping day. got the part to measure 30mm which is good enough for my needs.

there is no rhyme or reason, it really is awful.

It's been 4 years since I've used one now Brad, but isn't cut diameter one of the things you can change on the new job page when you first start off... where you input the sheet size/trim dimensions etc...
