I've not cut mdf on my machine as of yet and started doing a little reading on the subject. Is sourcing MDF an issue, as it relates to resin used, formaldehyde, other possible toxicity/production issues? Looking for a reliable source for 1/8 and 1/4 inch material, which could be the Lowes down the street unless you point me in another direction. Thanks in advance for your comments and any thoughts you have on cutting and settings.
