Mesa 7i92M Support

First check the setings in aspire, and make sure the output gcode is correct, or even better write a smal gcode to do a square, and just repeat that square several times. Post a picture of it.

Your recent suggestions cured the stair-casing issue. Thanks.

You may be able to increase the acceleration (2X maxvel is very conservative = 1/2 second to full speed))
but you will lose steps with too much ( and run slower than necessary on small radius curves if too little )

Simple shapes work well. Today I ran a 3D carving and there were lost steps occurring on all axes. Ideas?

Increase the step timing to at leas 15000, make a round shape and a square and check dimensions.

Is that setting in the ini? Under?

In your .ini file for each axis/joint

What am I missing? Thanks
