3D Printer Kit RAMPS 1.4 Control Board 5Pcs 4988 Driver With Heat Sink
A part of the review has been auto-translated.
Product (as always with Banggood) arrived well within the stated delivery times and was well wrapped and protected which was lucky as the packet had obviously been dropped in the post as one of the corners was dented, but minimal damage (a couple of bent pins that were easily sorted) occurred. The stepper drivers were all well soldered and the heatsinks applied well without causing shorts across the pins (I've seen some poor quality ones on ebay that do!). Mine came adjusted almost perfectly but maybe that was just lucky, although I obviously had to adjust one of the them for the z-axis which uses two motors on my build. The only slight gripe I had with the steppers is that the plastic around the pins had not been cut away cleanly so I had to cut these down a little in order to be able to fit them end on end into the ramps board. The ramps board itself is great. All the soldering is well done, all the jumpers set correctly (do make sure you check yours though!) and the quality of the components looks good, especially considering the very reasonable cost of the board. Like all ramps boards however it uses screw down connectors that are not rated highly enough for the potential 16amp draw. I've not had a problem with this but have seen a few melted ones so if you are running a high draw setup it might be worth soldering the connections direct to the board instead of using the connectors/ Overall a great board, with good steppers, at a fantastic price.
Hi I bought 2 sets of these and they came in due time. The problem is that the heatsinks are missing the special heat transfer adhesive and I can't use them. Why did this happen? Also one set was completely different that the other, especial the drivers. Is it possible for banggood to send me the heat transfer adhesive ASAP ?
