Very nice.

I think you need to change the title of this thread Bengt.

It does not look low budget anymore!

Thanks guys.

To me this is low budget as almost all parts are more or less to no cost. So far only stepper-motors, connectors, THCAD300 and PSU's have been thinning my slim wallet.

Next is to get all wired up and start testing the PC/MESA 7i90HD. Then it is time to have a look at PlasmaC and most likely I will need some advice from you guys.

Will probably shrink down my mechanical size to 500x500 as I do not have the space for the planned 500x 1000 that will be a bit heavy and cumbersome for an old fart like me to move from storage to cutting. More details to come but still same design.

Two hinges can do wonders ! Bolt it to the wall and bring it down only when you need it, otherwise it stays there kissing the wall and out of the way.

with 500x500 the Education cheep 700euro mashine jumps in at all costs including plasma s-cut50 with p80 nozzle
it is realy a low cost crap deal but it cuts the things as it shoudt
if you get all your EMI solved

If it was that easy, I have no wall space to to that ;) I will have to make a stand that will be outside all year around and the CNC-frame to be stored inside when not in use.

We will hopefully soon see what kind of EMI issues I will have.

Well mesaflash is telling you in a rather terse way:

ERROR: you must select transport layer for board

did you try mesaflash -- help ?
