Ok i am still having issues with my machine not cutting a straight line, it keeps getting these wavy jogs, i have re calibrated more times than i can count, when cutting squares and rectangles the lines leading away from the machine are straight but lines running parallel to the machine have a wave to them, its in the same spot on top and bottom in the same direction any other suggestions other than re calibration ![IMG_1686](https://us1.discourse-cdn.com/flex016/uploads/arcdroidcnc/original/2X/0/0056139d8a8cd0cc8face6ecf4034f2f7a77e0f3.jpeg) ---

@Joelsams Could you lay the metal in front of the Arcdroid approximately where it was when you cut it and take a picture from above? I was having a similar situation, but don’t know if it is the same thing or not without pictures. Thanks ---

If you are standing behind the AD, is the curve in the cut on the left? If so then that is the same thing that mine was doing. Andrew and I were on the phone for over 2 hours, off and on, trying to figure it out. We tried everything! It was my dumb luck that figured it out! I had the AD plugged into an old power strip that was on the same circuit as a small air compressor. When I changed the power to a circuit that had nothing else on it, the problem went away. You said that you recalibrated the AD many times, make sure you go into settings and start from default. I hope this helps, it fixed my same problem. Thanks Henry ---

I can’t say enough good things about the service from Arcdroid. Andrew has been more than patient with me and my self inflicted problems. He might take a little bit longer to answer an email sometimes but I know from experience about being self employed. Sometimes you get way too many irons in the fire and time gets away. He has always responded to my emails! ---

Did you contact Andrew about this issue? If you can’t get him on the phone, you can always email. He has always responded. ---

Well it is a reverse curve, it starts out in and then out, it is also curved on the top side as well furthest from the AD, and the only other item i have plugged into that circuit is a chop saw that is not used while im using the AD, i always start from default settings when re calibrating, thanks for your help ---

Yes i am more than happy with service from andrew, he is a great person, this will all get sorted out ---

Not yet, i thought i would try the forum first, i know he is busy, sometimes he comments on the forum ---

Try a different power cord and make sure it is on the opposite side of the buss inside your distribution panel. How I figured out that I had a problem with power was, Andrew had told me to increase the amount of torque on the X&Y axis motors and when I would go back to that setting, the AD had reset the settings from where I had manually set. Andrew said that the AD would change this setting if it was overloaded. Hope this helps. ---

Well i had my whole shop wired by a electrician for specific things, so the plug is right next to my AD so no extension cord ---

Try mounting up a Sharpie marker to the head. Run your program and see how straight a line you have. This eliminates plasma interference, plasma cable influence on the arm motion, and distortion of the material due to heat. If it’s still not straight it really is a calibration issue…. ---

The things I have had cause this problem were: -drive belts getting loose but this caused more of a jerky cut -the torch not being square in the holder, this would cause cuts to be straight and then curved depending on the direction the torch was leaning and direction of travel. -I have also had thinner material move from heat expansion when it was pressed tight against the ARCDROID base. this would give me a cut that appeared to bend towards the ARCDROID because the material was growing away from the ARCDROID. you can test this with BobD’s sharpie idea ---

Hey @Joelsams Did you get this issue fixed? I have the same problem and nothing I have tried has worked. Like you, I have recalibrated many times, always from default settings. I’ve done the Sharpie test and it looks identical to my cuts. My calibration data shows good as well.
