| All axis or a specific axis? How much does it shift? One revolution of the motor? If a marker pulse, used for homing, coincides with the home switch, variations in temperature can make home vary .100 inches as the switch may make just before or just after the switch. George

| Sorry G...... All axis or a specific axis? How much does it shift? One revolution of the motor? If a marker pulse, used for homing, coincides with the home switch, variations in temperature can make home vary .100 inches as the switch may make just before or just after the switch. OK been way to busy running parts to reply in a timely manner. Its x and y and I now understand what you ment by temprature change after reading your message more carefully. so if its a marker pulse , how do I correct it ?  |
