Looks like it was the diode inside the encoder. Are getting a new printer instead. Did a short time fix, connected a power supply to the motor and controlled the speed that way.

Differant machines have differant types of control. smoe use pulse motors with encoders and are controlled by PMD pulse motor drivers. Most of these will have parameters to determine things such as fast over shoot, speed for certian tools and varati

Hi, 1. Take a multi meter and measure the voltage - I assume it is a DC motor(probably 24V). If you don't, check power supply,cable, relays and Driver for the motor. If you do have voltage, check sensors(sometimes sensor activated may stop your con

Problem is solved! There wasn't voltage on motor inputs (only 5-10V AC) when the motor connected correctly, but was ~210V AC without motor. Firstly, I exchanged the motor speed control relay (Panasonic G-series type), but the result was same. (the a

We had the same motor problem with our My12, whenever we would get the sound we would go through and slow down X accel speed in any packages and the placement accuracy as well. After doing this for quite a while we finally tried updating the motor c

Hey, Peter. back in the mid 90's I reversed engineered their drive system because of a dispute over print speed malfunctions. I prooved correct that they had made published claims about their drive topology that were not true. They agreed to redes

If you want to vary the voltage to control the motor speed, then this is not the correct way. Though you can use LM317 for reducing the votage (using a 5K potentiometer) which will sure reduce the speed but it'll reduce the torque tremendously. For D

I have an application I'm trying to solve which would allow me to vary voltage going to an Electric Solenoid at 24v ~3.0amps DC. What I want to do is create a device to vary the voltage going to the Solenoid using a pulsed digital input. I have a mot

Common problem. Start at the Encoder and measure the 5v square wave. Trace it back to the Frequency to Analogue converter, then to the controler. I assume that your conveyor is in good shape. i.e. With the motor disconnected, the chain should flow f

We have a couple of Zeva/Juki PM570L's. One machine has developed a fault with the z axis motor. It is continually 'buzzing', we have checked and there is 24VAC on it. Although even on the other machine there is AC voltage on the motor. We have sw
