alternative to gecko G320

[opl505e]

hello all,

Im in the uk and want to find alternative drivers that are similar to the gecko G320, gecko don't seem to be sold over here in the uk.

So im looking for

20A 80VDC
PID feedback servo drive
Quadrature encoder inputs
5VDC 50mA encoder supply
Opto-isolated step and direction inputs
20kHz PWM
Current limit settable 0 to 20A

Give us a list of suitable drives at the same price if possible.

I don't believe anything else exists in Geckos price range . Rutex would be the next option, slightly more expensive than Gecko. www. rutex.com

Umm am thinking of buying 2 geckos and getting them sent over for the X-Y, however do i really need a third just for the Z axis plasma gun positioning?

Is there any neat tricks to handle the simple z axis gun operation?

rutex.com drives . Price is the same if you count on buying a scope for gecko.
Shipping looks like 20 to 40 compare to size and speed.


I’m not a plasma guy but over on the mach3 boards there seams to be allot of people needing and using the touch height setup for the z.

I could guess it would do with how well you need it to cut and how large of metal you cut. The larger it is the more warped they seam to get.

We ship direct to the UK every day. The fastest shipping is UPS, takes 2 to 3 days and costs about $65 for up to 6 drives. Global Express (also trackable) takes 5 to 10 days, costs $28 for up to 6 drives.

You don't need a 'scope.:-)

"You don't need a 'scope.:-)"

but it sure doesn't hurt! The way I see it, Rutex has you beat on ease of tuning and max position error before fault, and you have Rutex beat on price and robustness. A pretty even match.

God knows I can't get by without a scope and I like even matches.

Mariss,
How big are the G320's in their delivery boxes + how heavy?
I have an aunt in San Francisco who I could get the geckos delivered to, she could then wrap them up as a present and I could avoid import duty.
So whats the price to deliver to san fran?

Thanks

Rutex also has differential encoder input.
