I was hoping some of you might be able to lend me a hand by running a simple test using the attached mpc file.
Basically, I've been having trouble with random X-axis motion when drilling holes. Around the new year, the machine made a return trip to Texas to address this problem and another problem related to Z-Axis misbehavior. Unfortunately, the random X-axis motion appears to be unresolved. So, I am wondering if this is a problem specific to my machine or a problem for CarveWrights in general.
My machine has exhibited this behavior from the get go (I ordered it last summer), and unfortunately my projects are dependent upon resolving it.
Here are some more details. Using the attached mpc file, the machine should advance the X-Axis (sandpaper drive) and then drill a row of holes. It should advance the X-axis again and drill another row of holes, etc.
However, frequently on my machine after drilling a hole, the X-axis will jitter back and forth rapidly, generating a random X-offset. This causes the next hole in the row to be grossly malpositioned (see figure).
Note: I'm using autojigging and I've tried a variety of boards all of which were smooth, uniform, and square. Also, the regular hole pattern was made using the Copy Offset command. In addition, I've been through a number of software versions. The attached figure and mpc design file were made with version 1.115.
Chris Rawls of LHR Technologies suspected this might be due to a problem with the Aux Sensor. Unfortunately, the good folks at CarveWright appear to be swamped with support problems. Perhaps, someone here might be able to help.
Any thoughts? Would anyone be willing to try the attached design and report back?
My thanks for taking the time to investigate this.
