AR4MK2 Individual Motors on Stepperonline

Hi there,

I've started 3D printing the parts for the AR4-MK2 and have been preparing to purchase the electronics, however I noticed that stepperonline does not sell the motors in the AR4 Upgraded Kit as individual products.

I was hoping to purchase the motors in batches over time so as to avoid import tax (the main bundle is AUD $1085 which will incur an import tax of $180), as well as to make it financially easier for me to purchase the parts. I'm sure other hobbyist looking to build the arm have considered the same approach to aquiring the parts.

I can only find one motor listed for individual sale (23HS22-2804D-YGS50-AR4), unfortunately none of the other motors from the bundle can be found on stepperonline.com (http://stepperonline.com/) when I search for them. Are there any alternate/compatible motors that can be purchased individually that will do the job for each joint?

Cheers,

Jacob

I'll reach out to my contact at Stepperonline and see if they can sell each motor individually.

Richard

What happens if we somehow burn a motor and need a replacement. Another reason why Stepperonline should sell these motors seperately.

Jacob

I see the motors are now listed individually on stepper online. Thanks Chris!

Thanks Chris, that would be awesome! Not the end of the world if they can't/won't, and I appreciate that this is all open source and you've already done a lot by having a bundle available from a reputable online shop 🙂

Andre Monthy

Is there a link to the Power supply?

Jacob

No the power supply isn't listed on stepper online unfortunately. I got a Mean Well LRS-350-24 on amazon instead: https://www.amazon.com.au/dp/B07VRK86SP
