needed a 5-min clean-up/service out of the box to re-seat the blade and clean the adjuster threads. Blade could benefit from a hone but otherwise produces a decent shaving as-received. Good value for the price.

Purchased to run a GRBL build as a CNC router controller. Beware the pin alignment between the UNO, CNC shield and A4988 boards - i had to re-align some of the rows of header pins / sockets to allow the boards to assemble. Tested the UNO board - connects to the Arduino software and have downloaded a test program without issue. Note this board uses the CH340 USB-to-serial chip which is known to have an Rx buffer over-run issue with GRBL. On the CNC shield, the EN/X/Y/Z/A/5V headers (blue - top left) are not inserted all the way and are misaligned with the matching yellow headers - in my case a jumper won't fit to these without re-soldering. These headers are only used for development so i don't think it will matter initially. The shield is stamped as v3.00. The latest GRBL build (v1.1) and genuine Protoneer CNC shield (v3.51) have swapped the mapping of spindle enable and z-axis end stops; if using this shield with the latest GRBL the user needs to consider the implication of this. Solder quality seems fine across all boards. Entering into this project i was unaware of the specifics regarding the genuine vs. clone boards. I'll try these to see if they will work (i expect that they will) but i do so knowing that if they don't i'll be purchasing genuine boards to finish the build.

No identifying marks on the motor body, so no way to tell if the motors supplied match those ordered. Product ID's on packaging do not correlate to anything published on the product description. There are some battle scars on the body and mounting flanges which appear superficial and shouldn't affect performance. Mounting flange and overall dimensions are as described. Shaft is slightly longer (24mm) but flat face remains 18mm, potentially affecting pulley / coupling location relative to mounting flange. Wiring is completely different. Body is fitted with 6pin socket (description is hard-wired 4core cable). 4 core cable provided (approx 1m long) with 6pin & 4pin connectors terminated. Terminations do not match description. By testing, my winding pairs are Red-Green and Blue-Black, not as described. Connectors seem easy enough to rewire. Winding resistance (measured at the socket on the motor body) is 1.7ohms (+/-0.5ohms using my meter) which is out of spec (listed 1.4ohm +/-0.14ohm). Unable to accurately measure other properties. All 5 motors ordered were each tested and found to be as described in this review. I'll be connecting these up to my CNC controller as soon as i get a chance to identify any other issues. They otherwise seem to be fine, and i should be able to work around the issues listed above.

I purchased the 200mm lead screw. The thread-form on the lead screw seems very good (surface finish and dimensioning). Appears to have been parted off to length on a lathe (rather than with a saw) leaving a clean cut. One end of the screw has a burr which prevents the nut from threading on, but the other end if fine. The burr looks easy to clean-up so i'm not concerned. The brass nut is a little loose-fitting to the lead-screw. Very little play axially but a noticeable amount radially; difficult to measure but i'd estimate about 0.25mm (0.01") which is likely intentional so the threads don't bind. Seems very good and i don't expect any issues using this for the z-axis in a CNC machine.

Seems quite good. The first finger is a little less flexible than the rest (because its shorter). Some flashing around the edges from where the mould seams would have been which 'might' transfer a score line onto softer timbers, but nothing a small file / sandpaper cant clean up. Otherwise they seem quite good. They grip a standard 19mm (3/4") miter slot very securely.

Using as a PSU cable on a Raspberry PI. Tested OK.

Bore & tooth profile seem dimensioned correctly. Surface finish is very nice. Two grub screws at 'boss' end, 90 degree opposed. Grub screws are a bit short - would prefer them to be longer (and i'll probably replace them on assembly) to provide more engagement with the pulley and less likely to strip-out.

Its a tube. 1.75mm filament fits up the bore. Had a few kinks from how it was packaged for shipping. I believe these will straighten out sufficient for use.

Cloth / fiber reinforced belt (unable to tell which). Not steel reinforced, so suitable for most CNC / 3D printer applications and exactly what i was looking for.

As described. Packaged in a light-weight soft plastic tube with oil film for corrosion resistance. Dimensionally OK, and all of the bearings i tested (tested 4-5 of 60 ordered) spun fine.

As described. Input / output bore dimensions are OK. Machining and surface finish all appears very good. Two grub screws at each end (90 degree opposed). I'd prefer if the grub screws were a little longer (approx. 4.5mm long as supplied) so there was more engagement within the coupler, but i'm sure they're probably fine as-is.
