Hey all,
New to the forums and new to operating a cnc.
We started creating a vacuum table and for some reason the channels are not spaced evenly like they should be. We cut this on multiple small trials on different material, mdf..etc and it is consistently cutting unevenly. In the mach3 preview window the spacing is perfect as it should look and every time we cut this happens
The weird thing is the spacing is exact between every other one but as you can see one gap in the channel is bigger than the other.
Excuse me if this is obvious but I've done a lot of searching and cannot really figure it out. We do have a "hobby" machine if you would call it that, it is not heavy duty but I do not think this is a deflection/backlash issue since the material is not very dense and we are running it smoothly... my understandings of those may not be entirely correct either but I really need to get this figured out as right now we do not need exact cuts to make this vacuum fixture work but we will need very accurate cuts soon. What is weird is that it is even in the error so it makes me believe it is a setting somewhere.
I also tested the motors to make sure they jogged the correct amount on the DROs with a measuring tape on the gantry so it seems like it isn't a tuning issue... help!!? haha
I attached a picture to show on a test piece of particle board what I am talking about.
If this thread needs to be moved to another section please do so. Thanks for your help
