I have been working with several customers that are using the Bend-Tech Dragon tube plasma cutter and running Mach3 to control the machine. We are discovering an issue where on the last cut of square tubing, the x-axis (length of tubing) is having a delay in movement when changing directions. This is causing the end cut of the tubing to not line up with itself anymore. This issue can be corrected occasionally by changing the Lead-in/Lead-out location for that cut. We have compared the g-code files for the two cuts, and the values are all identical. Are there any known bugs within Mach3 when working with 4 axis or using Inverse Time Feedrate that would cause a delay in any of the given axis commands?
