I need help. My system has been running and stable for a while. I just completed the Meticulous Z upgrades and all was running well until two days ago.
Not sure how to classify or summarize my problems more concise then the following.
My system was running, in the middle of a program (cutting a simple circle near the middle/right side of the sheet about 12" from top of sheet), when it just stopped moving. I received the dreaded sled not keeping up warning. I am happy I was closely watching or it could have been a fire. I shut off router and worked to raise the Z up to Zero position. I had to restart GC completely to gain control of the Z axis to be able to move the sled or get any reaction in the program. I ran the motor test and it failed in the first direction on both L & R motors (Z worked fine). I checked (disconnected and reconnected) every connection, restarted everything and upgraded to the newest latest software versions.
I checked for any thing on the cutting surface that could cause the sled to stall (Nothing). My sled has a full sheet of HDPE under it so it is as friction-less as I can make it. I re-ran the program with the vacuum turned off (I thought maybe it was “sucking” the sled to table causing it to stall) and it still failed in the same manner in the exact same physical location.
I removed the sled and my counterweights and ran the motor test again with the chains slack. All motors passed in both directions. I re-attached my sled and then moved it around the work surface in all directions and it was perfect. I decided to run a “simple” program (a circle) in the exact same location I was cutting when the first stop happened without the vacuum on.
The exact same problem happened when cutting the circle. It stopped in the exact same physical location as all other times. The motor test again showed both L & R motors fail in direction 1.
Is it possible that I have dead spots in my motors? I can not think of anything else to do, change or check. I don’t know if there i a problem with the motors, the Arduino, the Maslow card…?
