  1. Need Help Help milling alupanel

    My current formula for 3mm ACM is an Amana #51446 (1/8" O-flute) at 19,000rpm and 125ipm, conventional cut. I do one full-depth pass with a 0.005" offset, then a second pass with the same feed/speed but no offset. This gives me a good edge and ejects most of the chips that otherwise like to...
  2. Anyone put grommets in Acrylic signs?

    I'd use a rivet - that's how my off-the-shelf version is assembled.
  3. Feeds and Speeds help

    For 3/4" plywood, I use a 2-flute, 3/8" compression bit, 19,000 rpm, ~150 ipm. I do two passes - one climb cut, almost full-depth (leaving a thin onion-skin to help with vacuum hold-down), followed by another full-depth conventional cut. The climb cut is good for hogging out a lot of material...
  4. Small Parts shifting

    Josh, this looks promising for my shop - I've been imagining a product similar to this, but I didn't know it already existed :-) I just ordered one to test. I'm curious to see how it does with small (~2") letters vs the part in the video. I'm guessing the mat combined with a down-shear bit...
  5. Small Parts shifting

    Would you mind sharing what make/model of premask product you're using for this? I just do routing - no printing or finished signs, so I'm not familiar with those products. I normally use Super 77 as noted above for small letters, but I haven't found a masking material that I really like yet...
  6. Vcarve cuts are cutting too deep

    Agree that more info is needed, but just a few thoughts/observations: - That's a pocket toolpath, not a v-carve toolpath; however, the blue lines and the state of the preview appear to indicate a v-carve path is in use. Did you perhaps edit the wrong toolpath before taking this screenshot? I...
  7. CNC Router recommendation

    We're happy with our CAMaster Panther. I'd think you'd want vacuum hold-down and a spindle (not router) with speed control to dial in your feeds & speeds, especially with polycarb.
  8. Atlanta GA area suppliers?

    I've recently started using Laird Plastics for my sheet goods, and have had nothing but great experience with them so far. They have a location in Austell, about an hour west of Dacula. My rep's info: Drew Knight | Customer Service Rep 8110 Troon Circle, Suite 100 Austell, GA 30168 Ph...
  9. Do you have a card?

    Good idea. Also enter yourself as a contact in your phone with all the details you'd want to share on a card. Then you can share that contact via text and your customer can immediately save it into their contact list without having to retype (or mistype) any of your numbers, etc.
  10. I broke my signs101 and then fixed it (I think)

    A quick "view source" shows that the site references a font called Roboto-slab. I'm guessing your browser normally substitutes something else, but once you added a font to your system by that name, it started using it.
  11. Anyone else went from crazy slow to crazy busy?

    I have a small supply of 1/4" clear extruded acrylic. I can supply you with cnc-routed blanks, sneeze guards, etc. - maybe even full sheets, if you don't mind a trip to South Ga. Shoot me a PM or email to james @ moultriemade.com, and I'll get you a quick quote. Thanks!
  12. Question Can't find...........................

    Looks like the navigation links on that page ignore the "begin" parameter. Clicking the "G" in your example takes you to https://signs101.com/members/list?begin=G You can go to subsequent pages by manually adding "&page=x" to your URL, so https://signs101.com/members/list?begin=G&page=5...
  13. need signs cnc'd my local sign supply wont do it for a few months

    I'm nowhere near you, but, if you can justify the cost of shipping, I'd love to help. :)
  14. What bit should i use to cut corrugated plastic on cnc?

    I have had good results using a Donek drag knife with X-acto blades for 3mm coro. I edit my cut file to soften any inside corners. This eliminates the need for the knife to raise up in Z to make a sharp turn. I do the same for outside corners, or add loops if I want them to stay sharp. I'm...
  15. Question Face Sheields

    I just ordered 5 sheets of 0.02" PETG here: https://www.professionalplastics.com/PETGSHEET?prrfnbr=125159&child=156814&qty=1&calc=calc29 About $213 including freight.
  16. LDF spoil board

    My last purchase was $29/ea for 4x8x3/4 "ULDF". This was from Hood Distribution out of Jacksonville. Delivery was free, but they have a minimum order of about $400 I think. I'm about 200 miles from them, but they have a truck here every week serving the local cabinet shops.
  17. LDF spoil board

    3/4" should be fine, assuming you've got a reasonably strong vacuum. I've always used 3/4" in the past, and replaced it when it got down to 3/8-1/2 or so. As it gets thinner, the exposed areas become more leaky and it's harder to maintain a good seal. Just this past weekend, I decided to try...
  18. LDF spoil board

    I've used both LDF and MDF and I found that any difference is minimal. With either, be sure to skim cut the bottom side to remove the smooth/pressed surface before flipping it over and attaching permanently. I've been doing some experimenting with this lately, I tend to think that your...
