Hi,

The latest versions of Polyboard and Optinest can now manage double sided machining either by flipping individual parts or the whole sheet .

Here's a link to a document in our new Help Centre that explains how to use these new features.

Hope this helps,

Yes. That seems better

Boole are doing a optinest hack for me at the moment to allow for full sheet 2 siding which is lacking on the program at the moment.

We have just started doing two sided fully and the accuracy has to be less that .5mm on a sheet flip to get perfect results.

Its definately the way to go to speed up the process and stop errors with the lateral thinking to keep fittings on one side.

Ill let you know how it works out.

The rotate on the offcut, im getting around by rotating the whole nested sheet on VCarve and just writing on the print out that it is rotated 180deg.

It does work, but im a bit OCD with the process and would like to get it totally automatic.

  

Yes we used to do that but the note on the sheet got missed a few times and we ended up wasting material. Found it better to also have a rule where offcuts are put on the machine so the home corner is intact and fix the error in software than righting notes on the nests.

We arnt doing anything 2 sides really, have done on the odd occastion but try to avoid it as much as possible and design it out if we can.

We have a 5mm offcut trim set up to allow for damaged edges or missalignment, which we dont then cut on the CNC so we end up with a diference sized offcut on the computer and in real life.

For each offcut I manually edit the offcut DXF coordinates from 5,5 and 5,1195 to 0,0 and 0,1220. If we then also need to rotate or flip the offcut in the software so we can relocate the offcut in the home position we edit the DXF coordinates from 5,5 and 1215,2395 to 0,0 and -1220,-2440 for example. Its not the end of the world but it is something that the software shouldnt be making us do I dont think.

Ive been taking off the 5mm trim.

But having a manual trim cut of 1215 x 2435 on the CNC memory.

Nesting with no trim cut, but a very accurate measure on the tool diameter (5.98mm)

Then when the offcut come out, it is accurate, but when cutting the outer edges are cut very tight with no allowance, but as long as the cutter diameter is perfect, it is ok.

What are you doing to get round it and are you two siding.

I dont know how else you are meant to use the program to not need to do this every once and a while. Would be interested to know if there is a better way of using the software to avoid this step.

Hi Ness

And again. Kerfworks and us must work exactly the same and this is an issue.

Being able to rotate the offcut is important too.

Hi,

No problem, thanks for the suggestion, I'll send this request to the development team.

We find ourselves having to edit the offcuts in optinest frequently. If we are left with a large "L" shaped offcut we need to rotate it so it is more accurate to locate on our CNC machine so it is like this "¬" for example.

Could we put in a request to add buttons that would allow you to mirror and rotate the offcuts without manually having to alter the -/+ of each of the coordinates in the offcut manager.

Cheers
