Re: securing a spoilboard
I just stumbled on this very old thread. I can explain what is going on with the Precix if anyone is still interested. It is a design issue.

Re: securing a spoilboard
Larger FT machines have the option of bolting it down. The machine comes preprogrammed to drill the holes in the correct spot on the board. It's then a case of bolting it down. Done.
Re: securing a spoilboard
I just joined the forum. Yes, I would love to hear what you know about Precix. I just purchased a used Precix 9100. First CNC machine. I honestly don't know what I don't know at this point. Any assistance would be great..!!!
Thank You..!!!
Re: securing a spoilboard
The problem is that those 1/16" holes do not allow enough air flow to work with a spoilboard. They'll sort of hold a piece right down to the plastic strips (if they are still there) but then you can't cut through without cutting into the plastic strips. The former head engineer of Precix has claimed in the past that this is how it should work and you just need to replace the plastic strips when they have been flycut too many times. It is no picnic to get those strips off........I know first hand. This was a terrible design right out of the gate.
The solution is to mill off the plastic strips and then cover all those 1/16" holes with 4" wide aluminum tape strips. Just make sure the surface is good and clean from all minute pieces of debris.
Then you can design and build a proper through vac hold down system that sits on top of the T-slot extrusions. Once the grid board is made and in place you just have to mill down into the air flow cores of the T-slot extrusions to transfer the air flow up to the spoilboard.
I worked this all out on the used 9100 I purchased in the summer of 2018. My new spoilboard system works beautifully and is removable in 2' x 4' sections so the T-slots can still be used if desired.
Feel free to contact me directly if you want to discuss this in more detail.
