Plastic experts help needed.
I have a DIY FLA CNC machine and works well. I made a vacuum box from MDF and sealed all sides but the top. Using a shop vac to suck vacuum. It seems to hold down my Styrene sheets (0.040') but when cutting the parts I loose vacuum. My question is what would you recommend to hold down the sheets as the vacuum system does not seem to work. I am using a upcut bit. Afraid that when using a downcut I get chips under the sheet and then also lift the sheet.
Would love to hear from all of you!
Thank you!
