Need some help, Machine not carving straight lines

Postby rschaeffer83 » Wed Jan 01, 2020 10:00 pm

I will upload some pictures to give you a better idea of the problem. I thought maybe the angle of the cutter was wrong but when I tried this test it looks like each triangle has something wrong with it. Most of the lines are bowed in and some of the corners don't look right also there was some dog bones while carving a sign earlier.

I am tramming the spindle now and I see that it is .050 off on one side. Could this be the reason for it not carving straight lines or is it something else?

I am hoping you guys can help.

I don't think its a program issue this is definitely a hardware problem. I just changed the spindle out to a smaller one and also made a new and stronger bracket to hold the spindle in place. So as soon as the spindle and bracket was changed I noticed issues.

If this isn't that right section to post in please let me know.

It could also be that your cutter isn’t the exact angle specified in your tool set up. This is usually the cause of dog bone corners on v-carves.

Draw a thin rectangle and try changing the angle in your cutter set up until you get a perfect cut for the rectangle.
