FoxAlien R57 Y-axis Rotary Roller Engraving Module for Cylindrical Objects Curved Surface for 4040-XE CNC Router Engraving Machine

Need to change wiring as does not plug and play, make sure you make sure that it will work with your machine

I returned it. Got discouraged with the lack of information, things like software setting changes etc

To get my unit to work without the motor stalling, I had to install bearings and shims on the idler rollers, and had to machine custom spacers to go between the bearings. 5x8 RC car bearings fit but wont work without proper spacers and shims. The pulleys on the rollers are too small (20T) - I swapped mine out with 40T pulleys and a longer belt. Without the bearings, its too sloppy when you loosen the belt enough to keep it from stalling. It would be a good value if you didn't have to spend an extra $50 to make it work.spacer: machine stock unit to length (0.463)backup washer (flat side towards shim): NAS620-C10 https://www.amazon.com/Finish-Stainless-Military-Specification-Washers/dp/B088CSGM97/ref=sr_1_14?dchild=1&keywords=nas620-c10&qid=1633908072&s=industrial&sr=1-14bearings: https://www.amazon.com/gp/product/B07SGRKBDG/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1pulleys: https://www.amazon.com/gp/product/B07K6BRL4K/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1shims (0.3mm): https://www.amazon.com/gp/product/B091YBHD43/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1belt: https://www.amazon.com/gp/product/B081NKJ56L/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1

I purchased this roller. Out of the box looked robust and well made, but I got so busy that it took me two months to use it. Here is the problem, first, FoxAlien does not supply the extra cable to connect to the engraver. You have to use the same Y cable of the engraver to connect the roller. The problem is that FoxAlien places the Y cable through the arm of the engraver; therefore, to use the roller, you have to remove it, which was a pain (had to use a wire to put it back)Second, it took me hours of trial and error to make it work with Lightburn. The owner's manual gives you no clue how to set it up. And finally, when I finally had it connected, the motor was slipping (yes, like a bad transmission). The roller could detect the software, but the motor skipped after 2 seconds of engaging. Luckily, Amazon customer service understood my problems and refunded my money.I still believe in the brand and quality of the product. I just had bad luck with the exceptional faulty one.

Disappointed. I ordered an engraver and this rotary. Rotary arrived on time but my engraver was damaged. By the time I received my new engraver and hook it all up the rotary motor will not spin it only vibrates. Now because I am past the 30 day return I don't have a return option. I guess I am out $135.00.
