Hello All,

My Handibot is having issues with cutting parallel lines. It will skew the lines so that a standard rectangle turns into an irregular parallelogram.

I have several pictures attached showing the issue as well as the sbp file. I cut a test piece with a simple rectangle to easily show the issue. I am using VCarve Pro and the Profile/Outside toolpath option.

Here are descriptions of the image files:

1: Picture of the simple rectangle vector on the VCarve software. Picture of the toolpath in VCarve and the preview of the toolpath. Note that VCarve expects a perfect rectangle to be cut.

Now I go to the Handibot and load the sbp file.

2: When I click the "Preview Job" icon this window pops up. "Be careful, some issues appear in this file. The machine may not do as displayed here."
3: This is the preview of the toolpath in Handibot. This is where you see the issue arising. It is clearly not cutting a perfect rectangle and is instead skewing every line. The beginning and end of the toolpath don't even meet up together.
4: This is the picture of what Handibot cut out of the blue foam I use for testing.

Here are the specifics of my software and firmware.

VCarve Pro - ShopBot Edition
Version: 8.517

Version: 1.7.1

Just to be sure, I'll mention what I have for the drivers. We played around with these values to try to get the rotary axis to work. However, I am pretty sure we put everything back to what it was.

Channel 1 is X, 2 is Y, and 3 is Z. Direction is Normal and Unit Value is 4000 for each.

Please Help!

It doesn't look like there is anything wrong with your file. It reads correctly--the old ShopBot simulator shows the curves--and the handibot I have on my desk here simulates it correctly. The only difference between my handibot and yours is that mine is on version 1.7.2 of FabMo (our most recent release).

I would recommend performing an update: [sites.google.com]
not so much because I think that it is an issue with the software version--but that I think the process of updating will correct whatever setting has gone awry on your tool.
