Well, I got all my steel in. Now to cut it up and start welding.
I've also got to decide what to do with steppers.
I'm redoing my lathe at present also.
I'm going to use LinuxCNC with a mesanet 7i43 FPGA hardware step generator.
I need 4 drivers for the basic router movement, but I also want a rotary (4th) axis, so I need an extra driver.
I've got:
3x 387oz-in steppers (Voltage: 50V Max, Current: 3.5A, Inductance: 2.8mH)
A G540.
3x 280oz-in steppers (8 wire
http://www.probotix.com/specs/HT23-280-8.pdf) that I can wire bipolar parallel.
I need:
One more stepper - will get another 387oz-in I think.
One extra stepper driver
- Any suggestions on stepper driver?
- I have a 5amp 570oz-in stepper on my mill currently (under) driven by my G540, so I'm tempted to get a driver that will take full advantage of this stepper.
I'm looking very seriously at a CWD556 - it appears to be the exact same as a Keling 5056D, but is available quite cheaply. Does anyone have any experience with this driver?
So I'm tossing up whether to put 2x 280oz-in in dual drive to move the gantry on the router, and then use 2x 387oz-in on my lathe. Or use the 387oz-in on the router and the 280oz-in on the lathe
Gantry is likely to weigh 100kg (220lb) all up.
Dual driven with 20mm ballscrews.
(I'll be building an electronics 'cartridge' so that I'll use the same drivers and power supply for mill, lathe, and router. Just remove power and pull cartridge, plug in to next machine and plug in power).
