At some point in the future I might purchase a G0704 and CNC it. At present I have a Taig Mill with a Deepgroove1 Gecko G540 control box which I would like to use in the conversion. I know that I would have to get a larger power supply for it but I am would like to know the best available stepper combination to use with the G540.
On this page
G0704 Electronics Hoss suggests:
"Bare Minimum Recommendation - This runs at 50 Volts but only 3.5 Amps
Should be easier for newbies to setup but is definitely weaker. Don't expect
to be able to hog as much metal with this setup.**
(1) Geckodrive G540 4 Axis driver - $249 (with other purchase)
(2) KL23H2100-35-4B 381 oz-in stepper motor (X and Y axis) $49 / $98
(1) KL23H2100-30-4BM 495 oz-in stepper motor (Z axis) / $59.95 *
(1) KL-600-48 48V/12.5A power Supply / $129.95
Total = $536.90
* Run with a 1.33:1 pulley ratio (24 and 32 tooth pulleys) for 658 oz/in output."
But on Keling's page
Page Title one of the packages is:
"G540 3 axis package (one G540 + one KL34H295-43-8B, 906 oz-in +
Two KL23H2100-35-4B (1/4” Dual shaft with a flat) 381 oz-in + one
KL-600-48 48V/12.5A 115V /230V
power supply): $581.95"
It would seem that the Keling package would not require the 1.33:1 pulley ratio that Hoss suggests. In fact it would allow a Z axis stepper larger than the 570 oz-in stepper Hoss uses now. I realize that this probably not the optimum combination but it would speed up the Z axis.
Bottom line question, is there a better stepper combination for the G0704 using the Geckodrive G540 4 Axis driver that would perform better than Hoss's Bare Minimum Recommendation?
