If the parts you want are the octagons then lose all the other lines and separate each octagon by at least 2*kerf width. Adding to what Terry's said - you can't have objects touching - what about your kerf? and even if you intend to use the .DXF AS the path rather than have sheetcam generate an offset path, cutting over an existing kerf is not a good idea. Also the golden rule of "kerf to the left" is not possible if two or more objects share the kerf.

I found a wire to the motor that come disconnected which caused the problem with the motor hold torque.

Hopefully I caught it in time before any damage was done to either the motor or drive. It seems to be working fine now.

You're lucky - this is one of the most efficient ways to let the smoke out of a driver 

I'm going to contribute this to motors heating up

It depends on what you mean by heating up. Stepper motors are designed to withstand quite a bit of heat - some people say that intentionally running them hot is the way to get the best bang for your buck - I'll reserve comment - but if you can hold them without burning your hands, as I understand it - that's not too hot.

although it may speed the Output # ? switching time there is still a delay before the next line of code is executed when using M3 or M1001.

Hi Tweakie - The timings I've given in the thread (via scope) were between the edge of the ouput going active and the edge of the first step pulse on the next line that commanded movement. i.e. NOT the time it took the output to go active. Worked every time for me and like I say I got it down to ~ 0.05 seconds, but looks like one of those one's that don't work for everyone for whatever reason.

Cheers

Ian
