My machine is running nema 34 motors with Gecko 203 drivers. Sold by CNC Router Parts.
USB UC100 interface
I have recently installed a precision collet .
The machine cuts very well when it comes to larger items, but it seems to have a problem when it comes to smaller cuts.
Take a look at images below:
The first image shows a 0.5" x 0.5" rectangle cut close to the X / Y zero.
This next image is about 10" from the rectangle above, notice how badly it cut the shape. I even tried to slow down the fed rate.
Holes regardless of spiral ramping are not true, and it this case, the holes were drawn to be a specific distance from the edge, but they were cut at an offset.
Here is a circle.. notice how the top is deformed.
I am wondering if anyone has any idea on what could be wrong.
I have been told in the past that my machine could be loosing steps?
I have some questions:
1) are the nema 34 not adequate for small detailing work?
2) what causes circles to be deformed?
3) how can I fix this? / if I am unable to make these cut, these machine is useless to me and I need to look else where.
Thank you
