Hi there,
I have a Syil AEX250 CNC lathe that I have been running for a couple of years now with only
minor, easily fixed, issues.
Running Mach3 R3.043.066, licensed. The computer CPU is 3.40Ghz, with 2Gb ram.
Yesterday I installed an Ethernet Smooth Stepper, and jumped through all the hoops to get that
up and running, I'm very happy with it so far.
1 problem I have not been able to fix is the tool changer motor now overheats. Yesterday, when I
discovered the problem, I measured the motor case at 98 degrees C. Until yesterday the motor never
even got warm.
Today I was able to listen to the motor with a probe stethoscope, I found that there was no noise from
the motor until I made the first tool change, after that the motor continued to hum and began to heat up.
I went into "ports & Pins", "Input Signals" and turned off Active Low on Input #1, which is set to port 1 pin 15.
When this was applied the motor stopped humming. Turning on Active Low and doing another tool change
caused the motor to continue to hum after the tool change was complete.
Jeff, from Soigeneris, has suggested that the motor is not being turned off after the rotation and lock down
of the tool post. My testing above would seem to confirm this.
I'm hoping someone can point me in the right direction to solve this problem. If posting any files will help please
let me know which ones you need.
Best regards
Mark
