Continuing the discussion from Y-Axis Not Working, Lesson Learned:
So it jst takes off and randomly carves what ever it wants like a 3 year old drawing all over the nice carving. After it does so well the time before. Must be noted that all of them were brought over from Photoshop and svg file off adobe. Any ideas as to the random take offs?
try running the file with a pen or sharpie attached to your machine instead of the spindle
You should definitly try what Badwolf is suggesting,
you can also try “aircarving” that is, running a file with no bit in the spindle and the spindle turned off.
you may be getting electrical interference form the spindle crossing over to the stepper wiring.
which way is your fan on the arduino/gshield blowing ? Should be blowing cool air down or onto the sheild not drawing heat away.
Were the 2nd and 4th prints immediately after the 1st and 3rd? Possible over-heating of stepper drivers? I know my 3D printer will do stuff like this if the stepper drivers get too hot.
Thanks for the intel. And negative ghost rider. All issues suggested ran. No overheating. Fan was done correctly. Envioment is very very cool. Ect…just ran basic easel progam. And to no avail it did it again. BUT the ecentric nuts fell off. And three came loose. So…we left it loose and one wheel off to use this as a control. So we ran it again and the star went great. And to the 2nd star as a fail. With over one third of the wheels loose and off…so control for a base on the ecentric is not the case. Now what?
Ok. Take your fan off. And you will see white knobs. Aka know as pot. Thats abbreviated. For a word called potentioenter. This is located on the g sheild inside the ardeno unit. Go to the axis that is giving you challenges. Ours was the y axis. To see which one is giving you challenges. Run a dry test from one inch in one direction to 10 inches stepping up the inch as you go as not too lock up and hurt your motors. If it locks up or skips. Then you know that is the axis that needs to be adjusted. So, turn it clockwise one mark shown of several marks on the pot. Then test again. 1 inch threw 10. Stepping again not to hurt your motor.this will stop your random out of control unit. So in essence it is getting more current to the motor to adjust with your software thats telling it to go in that direction.
