Hello
First off i apologize if this isn't in the right forum/thread area,I'm new to this sight and still trying to find my way way around.
I like many of you have decided to build my own CNC system,jeeze i thought it was going to be simple,some stepper motors,a control board,a pc and bam! but nooooooooooo! its a lot more complicated as i have found out.
Ive ran into some major issues that i was wondering and hoping very much you guys could help me with.
I have settled on the following for my needs
Nema 34 step motors @ 1269 ozin of holding torque
Parker Compumotor E-AC series drivers.....
Parker Compumotor OEM300 AC power module.
Zent toolworks CNC carver or
Lumen Lab micRO-Kit......but modified for a custom size/ application.
That's as far as i have gotten,The only Parker compumotor E series is some I found on ebay @159.99 each+ shipping with 34 size motor with 8:1 ratio gear head and electro brake)and E SERIES AC powered driver....i want the DC version but just cant find them anywhere.(mainly cause AC confuses/scares the crap outta me)
I have been having a very nasty time trying to find a compatible controller board to go with this system as well
Thats why i have come to this wonderful sight to ask.beg and plead for someone who knows alittle more about what i have selected and what else i may need
,i know that i will need break out box for the drivers.
i will also need a controller board,still looking
right now i have the Parker Compumotor OEM300 power module chosen to power the drivers,but that in and of itself is confusing me. here are the specs on the engine
* Size 34 frame
* Static Torque: 1269.67oz-in. (8.97Nm)
* Rotor Inertia: 14.8oz-in2 (2.7gc-cm2)
* Drive Current peak/RMS: Series 3.13/2.21A; parallel 3.8/2.47A
* Detent Torque: 50oz-in. (0.35Nm)
* Gearbox Torque Rating: 50Nm
* Output shaft: 20mm w/ key
Whats confusing me is this
i haven't seen anything telling me if the 34 size motor is AC powered,is it possible that the E-AC micro stepping driver is AC in and of itself but converts AC into DC to power the Step motors?
Also if i use the OEM300 Power module does it have to be hardwired into my house's AC line by directly connecting it to the wires? some breakers will ineffably blow right?
As for the actual CNC machine i was going to use? well i was going to use something akin to the Zen Toolworks CNC engraver or LumenLab mIcRo Kit,but custom made by myself and on a fairly larger scale.(that is if i can get this Driver/motor,Controller,Breakoutbox problem straightened out.
i really like the motors ive selected because they have the highest torque Ive seen of any motor (baring the $230 each nema 34's) on ebay. i was going to use Vexta 5 phase steps but the drivers themselves are just outta my budget so i went with combo deals.
If anyone out there in CNC land is familiar with Parker Compumotor products ,especially their AC products,can you gimme a post i sure could use the help.
or if you have any better ideas how i can still make a high torque CNC table top machine or know of of better more affordable parts,please dont hesitate to drop me a line.
thank you in advance for any help,it is sincerely and greatly appreciated.
Keith.
