Review on Threaded Backlash Elimination Kit by BIGTREETECH Direct by Arturo Reyes

Cr10s require an 8mm x 8mm T8 model. Two problems: The nut under the extruder is too wide when the extruder is installed. If you have switched to direct drive, this is not a problem. The second problem is that the holes are not wide enough for the shaft. You will need to remove the brackets on either side and use a dremel or file down some metal to give them the correct mounting spacing. They seem to work well, I upgraded my x and y stepper motors to the heavier 0.9 degree versions and the extra weight caused the gantry to tilt to the left every time the steppers ran out. This is one of the solutions. You can also upgrade the lead screws to the T8 2mm version and that seems to work if you increase the vertical resolution too. These 4 stars are only given due to a lack of detail as to which models apply to which printers and how many modifications are required to make them work. .
