1. If you re running a MK 5 extruder enter a value of 255 maximum speed into the Motor Speed PWM field Tab away from it and ReplicatorG will now tell your motor what speed it should run at when you turn it on Move Your Motor Back and Forth Next press the Forward button next to Motor Control You should hear your motor turn on and if you visually inspect it from the front you should see the motor shaft rotating clockwise Click the reverse button and it should move in the other direction If your motor is rotating counter clockwise in Forward first double check that you have pressed the Forward button If the Forward button is pressed that means the motor wires are reversed Now you need to turn off your machine open up the electronics bay and switch the motor wires This fix works for both DC and stepper motors Test Your Conveyor Belt Motor Note On Mk6 Mk7 extruders this will turn the extruder fan on and off The conveyor motor is controlled by the extruder board on newer ABP If you are using the Automated Build Platform you ll want to test the motor that drives the conveyor belt Click the Build platform belt checkbox at the very bottom of the Control Panel The motor should whir into life and your conveyor belt should move with it The direction of the belt should be towards the front and the ramp at the front If itis not moving at all or moving in the wrong direction go back to the electronic2. Kp Decrease Increase Small change Decrease Degrade Kj Decrease Increase Increase Decrease significantly Degrade Kg Minor decrease Minor decrease Minor decrease No effect in theory Improve if Kg small Chart via Wikipedia The parameter chart describes howeach visual characteristic on your Temperature Chart wil be effected by an INCREASE in the P I or D parameter Labeled Kp Ki Kd The image labels howthese characteristics would be apparent in your Temperature Chart For example if you are not able to reach your set target temperature the image shows you ll want to decrease the steady state error and the parameter chart shows this can be done by either increasing P or increasing by a very small amount As another example if you are seeing temperature oscillations by more than a couple degrees above and below your target temperature you ll want to improve stability and the parameter chart shows us that this can be resolved in most cases by increasing D It is important to understand that this is very much a guess and check process yet you shouldn t need to tweak your settings very far away from the defaults After making a parameter change it is always required that the Extruder Board is reset for the changes to take effect Improving the Default Skeinforge Model Slicing Profile The default Thing O Matic Skeinforge profile that is packaged with ReplicatorG should produce some nice looking parts out of the box but you wan

17. Proper Belt Tensioning Tensioning Mechanism The tensioning mechanism on the Thingomatic is the motor mount Instead of holes there are slots where the motor is mounted This allows the motor to move in a direction parallel to the axis To loosen or tighten the belt loosen the bolts on the motor and slide it towards or away from the stage When you are satisfied tighten the motor bolts back down This may be a bit tricky on the X motor and you will need to take the top plate off the Y carriage in order to get access to the bolts Tensioning belts In general belts should be tight enough to minimize slack but not so tight that they start placing a lot of stress on the motor shaft or pulleys Once a belt is on turn the motor pulley with your fingers to gauge if there s too much resistance If the belt makes an audible noise when you pluck it with your fingers it is too tight The Thingomatic operation should be nearly silent If your motor makes a humming or buzzing noise your belts may be too tight To test if your belt is too loose rotate the motor pulley back and forth by hand If the stage moves back and forth in sync then you are okay If it lags behind the belt is too loose A more conclusive test is to print a cylinder from Thingiverse on your Thingomatic If any of the sides are flattened then the belt on the corresponding axis is too loose Testing Your Bot Connect to your bot Double check your voltage Th
