Sometimes there are issues with assembling your ShapeOko whether it be something that got overlooked or maybe it is something that is a common issue that people need help on ether way this is the place to go. If you don't see your issue then go to the forums and ask you question there.

Stepper Drivers

Stepper drivers are fragile. Never power on a driver that does not have a motor connected to it. If you do, the driver chip can be damaged or destroyed. Some of the TI driver chips are fairly resistant to this, but it is a good idea not to try. Pololu chips will be killed instantly, but can more easily be replaced. TI chips are soldered directly to the controller board.

Motors

Direction

If your motors spin the wrong direction, you can reverse the connections. Note that it is very important to disconnect the power to the motor drivers before doing this, as having the driver powered up while there is no motor connected can damage or destroy the driver.

Power Supply

It is recommended to use a power supply that can supply at least 4A, preferably at 24V (although almost anything between 12V and 36V will do). If your power supply cannot provide enough current, the motors may not function properly. It is also important to make sure that there is heavy enough wire coming out of the supply, as it can heat up if it is too fine.

Z-axis

Delrin nut too wide

Assembly Issue: Delrin nut too wide

Assembly Step Reference: Assembly step 6 Assembly step 13

Parts: SM-M08 Delrin lead nut

Forum Link: click here

Details

When mounting your Delrin lead nut it should have a gap on both side so that it can move freely in the channel between the v rails of the z axis Makerslide.

Some of the Delrin lead nuts were cut at 40mm exactly which is the width of Makerslide channel and this will cause binding between the lead nut and Makerslide.

Below is an example of what it should look like.

Solution

To correct this issue you can either cut, grind, or sand the lead nut.

Do not worry if it does not look perfect as all that matters is that it can move freely in the channel between the v rails of the z axis Makerslide. The important measure is the distance between the mount holes and the hole for the lead screw, the outside dimensions do not matter as long as they fit into the channel of the Makerslide rail.
