X and Y axis drift RESOLVED!

X-Carve Troubleshooting
1

Please help this problem is new for me. i only get to use my machine on the weekends due to work. so last week it was working great. i keep it in a tool shed out side.I just installed a new ACME rod that inventables sent to me due to the last one being bent, decided to do a test square to check performance. square should be 2 inch x 2 inch and .250 deep using a 1/8 inch bit you can see the drift in the picture.

Did you check your pulley setscrews?

3

do you mean the set screw? for the drive pulleys on the stepper motors? if so yes and they have lock tight

4

Check your grbl parameters and make sure that $1=255

You may need to increase your stepper motor current limit on X and Y.

So far, it seems that all drift is a result of…

  • Loose belts (they do not need to be extremely tight, just take the slack out)
  • Loose pulley set screws
  • V-wheels too tight
  • Current pots not set correctly (too high or low)
  • Noise from stock spindle dying

problem resolved! stock spidle was dying causing to much amp draw to keep it spinning causing the noise that gets sent through RFI to the steppers thanks guys!!
