Try 4-5m/min at 15,000 rpm.
Hi,

I set Aspire to profile cut a 400mm square at 100mm/s and timed how long it took to mock cut out the full 1600mm. This took 51.40 seconds. So at 30.9mm/s actual speed, clearly not the 100mm/s set in Aspire. The spindle speed is not set in Aspire but on the actual spindle.

I tried the test again using a faster speed but it gave exactly the same time to travel 1600mm. So it must be that motor tune setting are incorrect or inhibiting speed.

My config settings are 26 stesp- 2000 velocity - 1000 acceleration

(As as side note I recalibrated X and Y axis so they are scaled correctly).

lets say as a rule of thumb I wish to cut out 12mm plyood in forms less that A4 scale with a mixture of straight corner and curved shapes, 10mm slots and 8mm holes etc. So reasonable detail.

I'm a little bit stumped why I couldnt change its speed in Aspire and why 100mm/s does not translate to its actual speed. I'm missing something basic am I not ha!

Any ideas welcome

This is the gcode file.
