Hi guys,
After finishing my G540 powered Aluminium gantry design, and having a few teething problems, I feel I am making progress - but was wondering what realistic figures ppl are using for their rapids. or for clearing / roughing cuts.
My X axis ( single 380 Oz nema 23 stepper with 10mm pitch) I got up to 18,000 mm/min at 1000 mms accel - so I set the rapid at 12,500 and base acceleration at 1,500mm/sec^2
My Z axis - same but 5mm pitch - 3,000mm/min acceleration 1,500 mm/sec^2
My Y axis ( which carries the gantry ( around 70 kgs ) 2 x nema 23, 10mm pitch ) - uses 6,000mm/min with 1,500 mm/sec
Cutting wise, ( wood ) I have been using 2.2KW spindle at 50% speed ( 12,000 rpm) or 18,000 RPM, and around 3,000 mm/min 4-5mm depth of cut.
Any other guys out there with 2KW systems, or using Nema 23, could you comment on your rapids, and also you cut depth/speeds?
Here is a short clip of a Fusion360 spiral plunge, cutting at 3,000, with the above rapids towards the end.
