I have searched this site but not found a definite answer.
I need to use the M579 command to make time tiny scale adjustments to my X&Y axis on a Large Delta build.
I need to know where to insert the command with scaling factors.Is it in the config.g file or the starting script on my slicer(cura) ?
How is it properly done and saved?
Thanks all.

Thanks all the info..Sorry when asking about the STL for brackets I meant your lovely corner ones for the 3 towers not the ones back to the wall.
Oh and no you are not mad! Who can resist going bigger!
I have a WASPdelta 4070 which is now 6 years old but still going strong and a SEEMEcnc machine.Like you I am looking at taking the best bits of both and combining into a bigger machine.Don't really need an enclosure other than keeping dust out as I print mostly in PLA.Parts and sculptures that are than sandcast or investment cast in brass and bronze.
Is that what appears to be cork sheet between your glass and Ali plate?
I'm sure I'll be picking your brains over the coming months if that is ok?

Really impressive build..I am thinking of embarking on a similiar project in the new year.A large delta approx 700mm x 1000mm build height and have started the long hunt around for parts.I see you are using printed corner brackets and have opted for screwing the whole thing to the wall..Has this worked out? I was hoping to go freestanding.I could draw up the brackets and get them machined as I can't find anything really up to the job off the shelf.Would you share your bracket design? I too am in the UK.Have you gone for Nema23 or 17s with 0.9 on your towers?
Thanks.
