Others will have more experience here, but have you tried a simple square?
Things I'm thinking - superficially, at least, it looks like you might be losing steps in the x-axis, but I don't know/can't rule out if aspire has a mach3 post-processor and/or if arcs could be causing an issue?, If you repeat the test with a simple 40x40mm square then at least you can start to understand if you're losing steps due to acceleration or max feed rate. When calibrating my machine I usually run a 40mm square with diagonals routed as well (a X in a box) just to get a visual on linearity, etc.

Hi
The project itself does have a rectangle section that it did cut out fine it's just not in the shot.
I also recently ran staight grid cuts that appeared to work ok.
If you have some gcode I could try in mach3 that's not dine in aspire that would be helpful. The circle is suppose to be 8mm in diameter.

Hi, if you go to my blog it gives all the mach3 settings. It sounds like some of the settings are ok and some aren’t, so just spend a bit of time going through them. If you’re still unsure pm me and I’ll go through them with you
