Hello, I'm trying to fix this error and what I've done so far I cleaned (no scratches) measuring scale and swapped cards (gantry 1 & 2) and cleaned scale reader sensor. There are no spare parts, I'm just trding to narrow down the cause. Any suggestio

Hi, Procedure how to replace the x-ballscrew of CP642. 1. Before you remove the x-motor, remember the pulse of x-axis motor just it turn ON the zero set sensor. Pulse usually at 1000pls. +/-50pls. 2. Turn Off the machine. 3. Compress the two ballsc

What is the (initial position) ratio of pulse counts to home encoder pulse (relative to the home sensor). It should be 50% +/- 15% Run this test several times in between a warm up. I bet your numbers are all over the place. I bet you have a loos

you can not just take the motor off and change it. the motors have a home pulse singnial. the motor has to be in a certian position the home pulse position when the flag hits the sensor. When you remove the motor you have to mark the motor gear when

sorry. re-read your post. The problem is the home sensor relative to the home pulse. You're catching the wrong home pulse. a 10mm offset sounds about right for a 360 degree error. You need 50% +/- 15 % to ensure you always zero to the same phys

board input sensor sensitivity? maybe conveyor movement triggers it and because of that it sends pulse. conveyor moves few millimeters, how does machine act?

Thanks for the response Travis. I'd think the table would inch or move if it were stuck inching keys. The table would eventually trigger one of the overtravel sensors on this ancient machine. Much Appreciated, Steve

Tom, Mount one sensor at about 6 inch inside of the beginning of the oven conveyor and use its output as ready to accept the board signal. That 6 inch distance will give you timing and space between two boards entering in the oven. Tushar

Since you haven't received any useful advise I will throw my 2 cents in. I do not know this machine but in general what you describe is an axis that does not get it's home pulse in time. Many machines will have an in-range sensor that gets flagged

Thanks, I am extremely new to this, in fact it's my first board that I am attempting to put together. I just needed an out put that pulsed between 0v-.09v. I am using it for an oxygen sensor simulator and found this diagram. I will try that site that
