Thanks for these explanation, I appreciate! I’ll try to give you more information and to be clear.
In attachment you can find a quick sketch of what it will looks like. I use aluminium profile 40 series and 20mm aluminium plate (6082).
It will mainly be used to cut wood. I would like to test cutting aluminium and acrylic too.
I use 4X KL23H2100-35-4B with a 48V PSU and a gecko G540. Here is the specs of the motor:
381 oz In. Holding Torque
1.8° /200 Steps Per Rev.
2.55V Rated voltage
3.5 Amps Current Per Phase
0.73 ohms Resistance
Inductance 2.8 mH
I try to calculate with your formula (from: http://www.engr.sjsu.edu/bjfurman/co...iaformulas.pdf) to calculate the motor inertia but I don't understand what is "motor armature". Is it the length of the motor?
I was expecting a speed around 600/700RPM ( I was thinking that it was a decent speed for the size.(It is?)), a resolution of ~0.01, an accuracy of a least 0.1mm.
The gantry including every parts will weight nearly (a bit less) than 40 kg. The screw length of the X axis is 1250mm.
If you need other informations don't hesitate plz.
Thanks.
